  • Aiding the Paint Trade
    Time-Tested Performance

    There are a number of factors that cause concrete surface coatings to fail.

    1. Water flow within the porous concrete before, during or after the coating has been applied is one of the major causes of problems associated with concrete paints.
      SEAL-IT Concrete Sealant decreases the absorption by 25% ASTM-C-67 SEAL-IT Concrete Sealant decreases the suction by 35% ASTM-C-67
    2. Concrete dusts naturally. This creates a surface that is unstable for most coatings to adhere to. SEAL-IT Concrete Sealant resists dusting to abrasion by 100% *ORF Method
    3. Poor surface preparation. This may include insufficient removal of oil or wax from previous coatings or contaminants, surface salts already present or forming from inside the structure, or moisture on or inside the concrete.
    4. Surface is too smooth for paints to adhere to. The battle for the most part we believe, is moisture being carried to the surface. Moisture not only carries alkali and lime to the surface causing a reaction in the paint, but moisture is a major problem to the paint itself often causing bubbling, cracking or peeling.

    Oil and acrylic latex paints were not designed as a sealer or waterproofing agent. Best results are achieved when these products are used only as a topcoat to SEAL-IT Concrete Sealant.

    We recommend SEAL-IT Concrete Sealant as a necessary first step for any concrete surface prior to painting. SEAL-IT Concrete Sealant not only prohibits water flow to the painted surface, but provides a surface that is stable from dust, alkali, salts, and provides an etched surface that easily enables paint to bind to.

    Because the concrete is properly prepared for the paint to adhere to, customers can expect an increase in the life of the paint, as much as 300%. Needless to say, maintenance costs can be greatly reduced.

  • An Effective Concrete Sealer
    Time-Tested Performance

    SEAL-IT Concrete Sealant's compatibility with the components of concrete will not alter the color, texture, or any other physical characteristics of the masonry surface to which it is applied. It leaves a clear natural finish and no film or membrane, of any mil thickness, shall remain on the surface.

    For waterproofing, hardening, increasing density, and dust proofing of most concrete and other masonry surfaces. Seal-It Concrete Sealant preserves and extends the material's life, as well as extending paint life up to 300%.

    Prevents Seepage/Capillarity - SEAL-IT Concrete Sealant holds a hydrostatic head, stops seepage, dampness, molding, pitting, rutting, dusting, and protects steel within the concrete from rust and corrosion.

    Helps in Concrete Curing - SEAL-IT Concrete Sealant helps new concrete cure uniformly, resists spot-drying and hair checking, and provides a prepared surface for better bonding of concrete toppings, mastics and paints.

    SEAL-IT Concrete Sealant maintains the concrete's ability to 'breathe', yet prevents the penetration and flow of water, grease, oil, acids, and other destructive materials. Environmentally safe - SEAL-IT Concrete Sealant can be used safely indoors or outdoors since it is a non-toxic, non-flammable, fumeless, odorless, and colorless.

  • Atmospheric Pollution
    Time-Tested Performance

    Modern times have brought modern challenges - even when working with age-old materials such as metals and concrete. Deterioration of building materials is becoming a serious problem for cities and towns. The effects of weathering are more severe due to pollutants introduced into the atmosphere. Buildings, roadways, curbs and sidewalks are all subject to this new phenomenon. Atmospheric pollution is a major cause of concrete deterioration, especially in industrial areas. Sulfur dioxide in the air combines with rainwater to form sulfurous acid. This reacts with lime compounds in the concrete, forming Calcium Sulfate. Calcium Sulfate is only slightly soluble in water and is deposited on or near the surface, forming a skin. The Calcium Sulfate then crystallizes behind this skin, and differential movements between it and the concrete underneath, loosen the concrete and cause disintegration.

    The highest concentration of sulfur dioxide in the atmosphere is in industrial areas. Polluted air causes erosion, and surfaces are weathered away, leaving coarse exposed aggregate highly susceptible to deterioration. Spalling due to corrosion of the reinforcement can also occur.*
    *Compression strength (surface coat only). Results: +15% at 8 days; +23% at 31 days

    SEAL-IT Concrete Sealant fills the pores in the concrete over an inch deep forming a barrier. This stops the rainwater, which carries the sulfur dioxide, from penetrating the pores of the concrete and prevents the formation of Calcium Sulfate.

    SEAL-IT Concrete Sealant provides denser, stronger concrete that will resist chemical attack at the surface, protecting the more vulnerable concrete inside.

  • Capillarity and Seepage
    Time-Tested Performance

    "Seepage is one of the most costly and counterproductive problems industries have with concrete and up until now, solutions were usually expensive and the results were poor."

    Capillarity refers to the migration of moisture and water in masonry. Capillarity enables water to travel in any direction. The result of capillarity is seepage. Seepage is one of the most costly and counterproductive problems industries have with concrete, and up until now, solutions were usually expensive and the results were poor.

    Seepage leads to efflorescence problems, peeling or bubbling of painted surfaces, or attack and disintegration of adhesives, which hold down floor coverings. This will lead to damaged floor coverings and the concrete.

    Because concrete is porous, water will migrate from the water table up, or take in moisture from the surface and migrate down. Moisture will not only cause deterioration of the concrete, but will also cause equipment and inventory damage, unusable areas of production, and safety risks resulting in lost revenue.

    SEAL-IT Concrete Sealant will chemically react with the alkali inside the concrete. SEAL-IT Concrete Sealant becomes a permanent internal seal with a protection depth of 1 to 11/2 inches inside the concrete. This internal seal stops the migration of moisture, thereby stopping the costly damage of seepage, efflorescence, and the disintegration of adhesives and paints. SEAL-IT Concrete Sealant will hold a hydrostatic head.

    *ASTM-C-67-Section 25. Results: 35% decrease in suction.
    *ASTM-C-67-Section 13. Results 25% decrease in absorption.

    Concrete is allowed to breathe or transmit water vapor. Allowing the concrete to breathe is vital in maintaining the integrity of the concrete; however it is not characteristic of many sealers in the market today.

    Seepage situations have many variables and are often an involved and specialized procedure. Seal-It can determine the procedure needed to solve seepage by looking at each situation and assessing the best solution.

    There are 3 important factors when dealing with seepage problems that SEAL-IT can alleviate:

    1. The concrete can be treated when it is wet (which is usually the case in seepage situations)
    2. The sealant can be applied from either inside or outside of the structure. Excavation work is messy and expensive, and can be avoided with the use of SEAL-IT methods.
    3. SEAL-IT'S proven methods of application will give you long term results with 100% customer satisfaction.

  • Chlorides and Concrete
    Time-Tested Performance

    Calcium chloride has been the most widely used accelerator in the past because of its low cost and predictable performance. However, the use of calcium chloride also comes with these disadvantages:

    1. Corrode the reinforcement steel within the concrete, (particularly if the dosage is large and if it is not properly controlled)
    2. Reduce the concrete's resistance to sulphate attack.

    The presence of chlorides in the concrete, changes the protective quality of the environment of the steel, and is a serious cause of corrosion of the steel reinforcement. The corrosion of steel is a process where ions react with water and oxygen to form rust. The rust formed can occupy a volume over twice the original volume of the steel with internal pressures as high as 30N/mm2. This force is many times greater than the strength of the concrete and is responsible for the cracking and spalling that occurs. The severity of the damage depends on the concentration of the chlorides present in the concrete, as well as the variation of the chloride from one point to another. Soluble components of the rust may be leached through the cracks and appear as rust stains on the surface of the concrete.*

    Chlorides can also be carried into the concrete through water migration, therefore keeping chloride penetration to a minimum, is a major factor in controlling the integrity of the steel within the concrete. The chlorides already present in the concrete from admixtures and raw materials are there to stay, but you can do something about the additional chlorides that migrate to the interior of the concrete through water migration. SEAL-IT treats this problem from the source - water migration. SEAL-IT Concrete Sealant penetrates 1 to 1.5 inches into the concrete, chemically reacts with the alkali to form a permanent internal seal. SEAL-IT Concrete Sealant retards the penetration of chlorides, acids, and alkalis from entering the pores and causing irrepairable damage. The service capacity and the safety of the structure will be significantly increased by reducing the damaging effects of chloride penetration.

    Rebar that has rusted resulted in costly repairs to the concrete.

  • Concrete Curing
    Time-Tested Performance

    The chemical action which results in the setting and hardening of concrete is dependant on the presence of water. Although there is normally an adequate quantity for full hydration at the time of mixing, it is necessary to ensure that the water is either retained or replenished to enable the chemical action to continue. A significant loss of water due to evaporation may cause the hydration process to stop, with a consequent reduced strength development. In addition, evaporation can cause early and rapid drying shrinkage, resulting in tensile stresses which are likely to cause cracking unless the concrete has achieved sufficient strength to withstand these stresses. Methods of curing are therefore designed to maintain the concrete in a continuously moist condition over a period of several days or even weeks. **

    Improper curing can easily reduce the strength of even the best concrete by half.

    Many other properties of hardened concrete also are affected by its moisture content. These include elasticity, creep, insulating value, fire resistance, abrasion resistance, electrical conductivity and durability.

    SEAL-IT Concrete Sealant penetrates into the pores of the concrete, chemically reacts with the alkali within the concrete, to become an internal membrane below the surface.

    The concrete is not only aided in the curing process, but ultimate protection is provided in one application.

    Due to its chemical reaction, SEAL-IT Concrete Sealant forms a silica aero gel, which maintains optimum moisture levels in the concrete throughout the curing process. This helps in keeping the integrity and consistency of the cement gels constant throughout the concrete. After the curing process the concrete is denser, harder and permanently sealed. This results in a higher quality concrete.

    SEAL-IT Concrete Sealant allows the concrete to continue to hold enough moisture throughout the curing period in order for the cement to hydrate. Moisture loss, due to temperature and environment during the curing process is also retarded, therefore the concrete will not spot dry or dry unevenly.

    *ASTM-C-156. Results: Significant improvement in curing against hairline checking and spot drying.

    The concrete is not only aided in the curing process, but ultimate protection, in one application.
    Properly cured concrete provides improved durability. Well-cured concrete has better surface hardness and therefore is more watertight.*

    *Compression strength (surface coat only). Results: +15% at 8 days; +23% at 31 days
    Less downtime and not time restrictions, when curing and sealing concrete, is a major benefit to trades-people and building owners. Other sealer applications must be delayed for a minimum of 28 days after the concrete has been pored.

  • Concrete Dusting
    Time-Tested Performance

    Test results indicate that abrasion resistance is closely related to the compressive strength of concrete. Strong concrete has more resistance to abrasion than weak concrete.

    *As shown in the picture, even 'strong' concrete is damaged as time takes its toll on unsealed, untreated concrete. *Compression Strength (surface coat only) Results: +15% at 8 days; +23% at 31 days.   

    SEAL-IT Concrete Sealant delivers 100% improvement against dusting due to abrasion.

    Concrete Dusting (small particles of surface grinding away) can be caused by vehicular, foot, or machinery traffic over the concrete surface. It is a costly enemy of efficiency due to the damage it causes to machinery, merchandise, and environmental health.

    SEAL-IT Concrete Sealant causes a chemical reaction to take place with the alkali and lime inside the concrete to form an internal seal. This internal membrane increases the compression strength of the concrete by as much as 23% and surface abrasion is eliminated 100%. Costly floor coverings often used to control dusting, can be eliminated by the use of SEAL-IT Concrete Sealant.

    SEAL-IT Concrete Sealant will not wear, chip, or peel like most surface coatings, because there is no membrane to chip or peel. SEAL-IT Concrete Sealant forms an interior seal with a protection depth of 1/2 to 1 1/2 inches inside the concrete.

    If the concrete freezes just after it is poured, it will powder and dust exceedingly. Too much water in the concrete mixture will cause dusting and powdering. SEAL-IT Concrete Sealant prevents powdering and dusting by "binding" the concrete components.

    In factory or warehouse situations where equipment is dragged and tools dropped on the concrete, it is an economic necessity to use a product that does not chip, peel, or wear off.

    429 STUF is a non-slip sealer available in gray, clear & silver. Epoxies, polyurethanes and other specialty coatings will not do for you what 429 STUF will. Most other specialty coatings flow into the pores of the concrete and dry to a rock hard finish. However, problems start happening as the surface is damaged. Other products don't bind into the pores of the concrete; they sit in the pores and chip off easily.

    429 STUF, penetrates into the pores and expands as it cures, therefore locking the product into the concrete. 429 STUF is versatile in a wide range of environments including salt, chemical, acid and alkali.

  • Concrete Protection
    Time-Tested Performance

    The life of concrete is limited by a number of disintegrating factors:
    Weathering by rain and frost action is chiefly a function of water-tightness or impermeability, since leach and attack by the carbonic and other acids present in rainwater, and disruption by frost action, depend on the penetration of water into the surface.

    Chemical attacks such as industrial chemicals and wastes; sewage, animal and vegetable oils, fats, grease, milk, and sugars. Wear by abrasion from foot and vehicular traffic, by wave actions, and by water-borne and wind-borne particles.

    Concrete has the tendency to be porous due to the presence of voids formed during or after placing. It is usually necessary in order to obtain workable mixes, to use far more water than is actually necessary for chemical combination with the cement. This water occupies space, and when it later dries out, it leaves behind air voids.

    Gases such as sulphur dioxide and carbon dioxide in damp situations, attack concrete. Sulphuric acid also attacks concrete, but the attack from sulphuric acid is likely to be accompanied by abrasion. Sulphates of sodium potassium, magnesium and ammonium may cause serious damage to Portland cement concrete in the presence of moisture. This begins by expansion within the concrete, which may be enough to cause general expansion in the member.

    Cracking and disruption follow. Cracks provide a path for soluble chemicals to migrate into the interior of the structure causing deterioration of the concrete. Fertilizers often contain ammonium, potassium and magnesium sulphates. Generally, inorganic acids are destructive to concrete. These may also be released from some salts such as ammonium chloride and ammonium nitrate by interaction with lime. Leaching then follows. A number of fertilizers are soluble in water, enabling the chemical easy pathway to the interior of the concrete. Although petroleum oils are not known to cause extensive damage to concrete, they do penetrate into the pores and cause unsightly staining, with subsequent high maintenance cleaning as well as possible contamination of the soil below leading to environmental issues. Organic acids such as stearic, oleic, lactic and tannic all attack concrete. Lactic substances which are derived from dairy product have a most destructive effect. Vegetable oils, molasses, sugar, syrup, glucose have a fair degree of attack, acetic acid which occurs in vinegar and tartaric acid which occurs in some fruit juices all attack concrete.

    Sewage normally has an alkaline reaction and is harmless, but it may become acid by contamination with factory wastes and will then attack concrete. The concrete along the top of sewers can be severely attacked as the result of hydrogen sulphide gas being evolved from the stale sewage. The hydrogen sulphide is oxidized by anaerobic bacteria to form sulphuric acid which condenses on the walls of the structure. The attack may be rapid particularly in warm conditions and where ventilation is poor.

  • Efflorescence Protection
    Time-Tested Performance

    Efflorescence is a white crystalline deposit that can form on surfaces of concrete, stucco, brick or masonry. These deposits are water-soluble salts that come from the ground. For water to carry or move the salts to the surface there must be channels through which to migrate in a process called capillarity. Porous materials enable the salt to be transported with greater ease. When ground water, containing salts reach the surface of the structure, the water evaporates into the air, and the result is efflorescence.

    Any building materials in direct contact with the earth are potential sources for efflorescence. Low absorption is the best assurance against efflorescence.

    Ninety percent of your problem is moisture and capillarity. The moisture carries the salts to the surface through channels in the concrete. Without moisture as a carrier, the efflorescence would remain unseen below ground. Seal-It's Concrete Sealant provides a barrier to the migration of moisture, because it penetrates into the concrete, where it reacts with the alkali and forms a hydrostatic head. The moisture, or carrier, of the alkali is stopped, preventing the efflorescence from surfacing and causing deterioration of the concrete.

    Efflorescence and seepage are situations with many variables; therefore we recommend the advice and services of SEAL-IT when dealing with these and similar conditions.

  • Fertilizer & Sulfate Attack
    Time-Tested Performance

    Sulphates in solution attack concrete and cause expansion, deterioration, and eventual disintegration. In the early stages of attack there is little visual evidence of any change in the concrete, although there may be some reduction in strength as the chemical action proceeds. This is accompanied by slight expansion, which may not be apparent in the concrete itself, but may cause trouble at points of restraint. As the attack proceeds there is usually some change in color from the normal cement grey, and cracking or spalling occurs, starting from the surface in dense concrete, but penetrating much deeper in more porous concrete.

    Fertilizers often contain ammonium, potassium and magnesium sulphates. Generally, inorganic acids are destructive to concrete. These may also be released from some salts such as ammonium chloride and ammonium nitrate by interaction with lime. Leaching then follows. A number of fertilizers are soluble in water, enabling the chemical easy pathway to the interior of the concrete.

    1. Form in which the sulphate occurs.
      Easily soluble sulphates such as those of sodium, potassium, magnesium, and ammonium, react more vigorously than calcium sulphate or gypsum.
    2. Concentration.
      The higher the concentration of sulphates in solution the more serious the attack. The severity of attack is increased in circumstances in which a flow of sulphate- bearing water brings a continuous supply of the salt into contact with the concrete.
    3. PH value of the soil or groundwater.
      Its temperature may also be a factor at ground level, the activity of sulphate solutions increase with temperature. If the pH value is below 6 in acid soils, the rate of attack is likely to be increased.
    4. Permeability of the concrete.
      Permeable concrete, particularly if one side is in contact with moist soil containing sulphates and the other side is open to the air so that evaporation occurs, is attacked throughout its thickness resulting in an overall expansion and complete disintegration.
    5. Formation of cracks.
      Attack proceeds along the lines of cracks particularly when the movement of moisture along any crack is encouraged by one-sided water pressure of evaporation from a free surface.
    6. Sulphates.
      Sulphates of sodium potassium, magnesium and ammonium may cause serious damage to Portland cement concrete in the presence of moisture. This begins by expansion within the concrete, which may be enough to cause general expansion in the member. Cracking and disruption follow. Cracks provide a path for soluble chemicals to migrate into the interior of the structure causing deterioration of the concrete.

    Sulphate salts attack concrete only when they are in solution. It follows that attack is most severe when the soil conditions allow a free movement of ground water.*

    Because concrete is porous, and any foreign material can penetrate into the concrete as water-soluble, the solution is to stop the penetration of these chemicals by stopping the capillary action. SEAL-IT Concrete Sealant provides a permanent internal seal, which forms a hydrostatic head, barring the migration of moisture. SEAL-IT Concrete Sealant provides a water barrier so moisture as well as water soluble contaminants sit on the surface instead of penetrating and destroying the concrete.

    SEAL-IT Concrete Sealant also increases the strength of the concrete at the surface. This will retard attacks of harmful chemicals at the surface, protecting the vulnerable interior of the concrete, thereby increasing the life-expectancy and safety of the structure.

    *ASTM-C-67-Section13. Results: 25% decrease in absorption.
    *Compression Strength (surface coat only). Results: +15% at 8 days; +23% at 31 days.
    **Concrete Materials and Practice Fifth Edition

    Field tests with fertilizers containing primary sources of Nitrogen, Phosphorus, Potassium, and Sulphur have shown that SEAL-IT Concrete Sealant performs exceedingly well in protecting the concrete from the fertilizer attack. The life and integrity of the concrete have been dramatically increased by protecting the surface with SEAL-IT Concrete Sealant.

  • Fixing Alkali Problems
    Time-Tested Performance

    Alkali is never pure and rarely stable. It is made up of a combination of elements and almost always reacts with other elements.

    We start with hydrogen, then lithium, sodium, potassium, rubidium, cesium and francium. Francium is radioactive with a half-life of only twenty minutes. The other five are very active alkali metals. Each element has electrons and molecules, which are always eager to take part in chemical reactions with other elements. The two most important alkali metals are sodium and potassium. We find a hint of them in potassium carbonate and sodium carbonate. Sodium makes up 2.6% of the earth's crust and potassium makes up 2.5%, yet we never see them. They are always found in combinations with other elements. Neither of them could remain pure in air or moisture.

    The increased use of concrete subfloors in direct contact with the ground makes more important than ever, the complete understanding of moisture and alkali inherent in these subfloors and their effects on paints and floor coverings. Well known as the "alkali problem", this condition is primarily a problem of moisture. Alkali is present in every concrete slab and is more detrimental with moisture. On adequately ventilated, suspended concrete, subfloor moisture is not present in troublesome quantities.

    Where the slab is in direct contact with the ground or a poorly ventilated air space, moisture is brought up through the slab by capillary action. It dissolves the alkaline salts in the concrete and appears at the surface as a destructive alkaline solution causing spalling and efflorescence.

    Although moisture and alkali conditions may vary greatly, there is always sufficient moisture in the ground to come in contact with the alkali in concrete to present an "alkali problem" on subfloors affected by ground moisture. It is never safe to assume that a concrete slab will always by dry because is has been dry; moisture content may be small. When paint or floor coverings are applied, the moisture and alkali collects under the coverings. This often results in coverings buckling, warping, or separating from the concrete surface.

    Seal-It recommends SEAL-IT Concrete Sealant to alleviate this problem. Seal-It can seal and waterproof the concrete to eliminate spalling and efflorescence, leaving clean pores to which paint, mastics or adhesives for floor covering can effectively secure a better bond. The destructive moisture attacking problems, which causes deterioration to adhesives and paints will also be eliminated.

    Efflorescence becomes a problem when moisture is introduced. Moisture transports efflorescence through the concrete, thereby destroying concrete and the steel holding it together. 90% of the problem is moisture; SEAL-IT Concrete Sealant penetrates into the concrete, reacts with the alkali and forms a hydrostatic head, barring the migration of moisture.

    *Seal-It recommends certified and trained applicators for alkali sealant solutions.

  • Floor Covering Trade
    Time-Tested Performance

    Time constraints and budget limitations often leave construction projects overlooking moisture levels and soil PH when pouring concrete. A complete understanding of moisture and alkali inherent in these subfloors and their effects on paints and floor coverings is important.

    As the concrete is setting and commencing through its long curing process, water evaporates from the concrete. When this moisture is gone, it leaves voids and pores in the concrete. The pores in the concrete allow for moisture to migrate from the ground. The moisture passes through these voids and mixes with available alkali.

    When mastics or adhesives are applied to bind floor coverings to the concrete, the drawing action of the moisture is increased. When this moisture is drawn to the surface of the slab, it comes in contact with the adhesive. When alkaline water meets with the adhesive, the adhesive emulsifies or begins to deteriorate, resulting in bubbles, blistering, warping, cracking and peeling. The end result is the replacement or re-application of the adhesive. Floor coverings often fail due to one or more of these reasons:

    1. Moisture
    2. Alkali
    3. Hydrostatic Pressure

    SEAL-IT Concrete Sealant prevents moisture from coming in direct contact with covering adhesives or mastics. This will alleviate moisture and alkali collecting under the coverings which result in buckling, warping, or separating from the concrete surface. SEAL-IT Concrete Sealant causes an internal chemical reaction with the concrete, to become a permanent part of the concrete surface, and eliminates problems associated with floor coverings by its ability to hold a hydrostatic head.

    SEAL-IT Concrete Sealant will leave clean pores, similar to "etching" on the surface to which paint, mastics or adhesives for floor covering can effectively bond. It will also eliminate the destructive moisture attack which causes deterioration of the adhesives and paints. On surfaces where no covering is used, SEAL-IT Concrete Sealant will prevent foreign matters such as oil, grease, and acids from penetrating and causing spalling, pitting and overall deterioration. SEAL-IT Concrete Sealant enables easy clean-up and maintenance.

    Sealing with SEAL-IT Concrete Sealant is an aid in the floor covering trade and a 1-step process for curing and sealing. This is why for quality and efficiency, floor covering specialists count on Seal-It.

  • H2SO4(Sour Gas)
    Time-Tested Performance

    Sewage normally has an alkaline reaction and is harmless, but it may become acidic by contamination with factory wastes which will then attack concrete. The concrete along the top of the sewers can be severely attacked as the result of hydrogen sulphide gas being evolved from the stale sewage. The hydrogen sulphide is oxidized by anaerobic bacteria to form sulphuric acid which condenses on the walls of the sewer. The attack may be rapid, particularly in warm conditions and where ventilation is poor.

    In 1993, North American companies spent $1/2 billion in water treatment chemicals alone to fight corrosion and fouling. Reduction in chemical use, safety, and cost effectiveness are major concerns for the sewage/water treatment facilities.

    SEAL-IT Concrete Sealant fills the voids and pores in the concrete creating an internal seal that inhibits the growth of the bacteria.

    Because concrete is porous, and any foreign material can penetrate into the concrete as water-soluble, the solution is to stop the penetration of these chemicals by stopping capillarity action. SEAL-IT Concrete Sealant provides a permanent internal seal, which forms a hydrostatic head, barring the migration of moisture. SEAL-IT Concrete Sealant provides a water barrier so moisture as well as water soluble contaminants sit on the surface, instead of penetrating and destroying the concrete.

    The seal extends 1 to 1.5 inches inside the concrete, and is permanent. Reducing the breeding environment of the bacteria, hindering the formation of sulfuric acid. Sulfuric acid is the corrosive by-product of the reaction between the bacteria and hydrogen sulphide.

  • Preventing New Barn Syndrome
    Time-Tested Performance

    Historically, veterinarians have described New Barn Syndrome as affecting the sows, growers, and finishers.

    Sows: Hip, ankle, and hoof problems. The noted cause of these problems is the caustic nature of new concrete, causing a skin reaction on the bottom of the foot pads.

    Small cracks in the pad occur allowing bacteria to enter into the animal's body causing joint infection in the knees, ankles and hips.

    With this lameness, producers suffer losses in terms of increased sow culling rate, breeding problems, and other management difficulties.

    Growing and Finishing Hogs:

    New Barn Syndrome has been reported to also cause tail biting, and ear biting in growing and finishing hogs. Producers suffer losses from New Barn Syndrome in the growing and finishing stages due to increased culling of animals because of tail biting, ear biting and lameness.

    Experts are not sure why the chemicals in the new concrete may cause ear biting and tail biting in growing pigs. The lameness in growing pigs is caused by the same reason mentioned earlier with the sows.

    Existing gestation barns can be washed and sealed with SEAL-IT Concrete Sealant to help prevent bacteria buildup in the pores of the concrete thus preventing lameness problems.

    SEAL-IT Concrete Sealant seals off this caustic chemical from contact with the footpad skin, which gives protection against lameness.

    Concrete surfaces may be damaged by frost action either before or after the concrete has set. If the temperature falls below zero before the final set, the expansion of water while freezing exerts a force sufficient to destroy the cohesion between particles of the green concrete. The surface of concrete frozen before the final set has taken place, scales badly and becomes pitted. The imprint of frost crystals may often be seen on the broken surface.

    Disruption of set concrete by frost is caused by the expansion of water in the pores during freezing. Pressures are developed within the material progressively as ice formation continues. Scaling and cracking occur when the concrete cannot withstand the stress of the expansion and contraction associated with freeze/thaw.

    As liquid changes to ice, there is an expansion of approximately 9%. When ice changes back to liquid, stress is released. When salt is added to the equation, the rate of expansion is doubled.

    The use of de-icing salt exceeds 10 million tons in the US each year on roads, and about 3 million tons in Canada.** This salt use, increases the expansion rate, thereby increasing the damage done to concrete surfaces. SEAL-IT Concrete Sealant is the ideal preventative solution for freeze-thaw damage. SEAL-IT Concrete Sealant fills the voids and pores in the concrete and provides an internal seal, which will prevent the moisture penetration, thereby retarding deterioration, cracking, spalling and other damage caused from the stress of freeze-thaw conditions.

    *ASTM-C-666. Using 5% NaCl. Results: Improves resistance to salt attack during freeze/thaw conditions in presence of moisture.

    Concrete exposed to damp conditions such as road surfaces, reservoirs and dams, has a greater potential for damage from frost and freeze-thaw conditions. SEAL-IT can significantly reduce damage associated with freeze-thaw with their specialized knowledge and experience.

  • Wall Sweating Problems
    Time-Tested Performance

    The surfaces of most common concrete buildings have an affinity for water molecules. This molecular fill is proportional to relative humidity. At saturation levels, all voids, pores and capillaries can become completely filled. When the atmospheric condition, inside or outside, which causes the excessive moisture in the first place, is alleviated, the porous wall may become filled to the saturation point with moisture in liquid form.

    This condition then provides an excellent opportunity for vapor travel within a wall. In its travels the vapor may contact a cold area or “dew point”, and condense in sufficient quantities to reach the interior wall surfaces, to appear as wall “sweating” or “bleeding”. Both sweating and condensation can be greatly affected by temperatures, humidity, wind velocity, soil moisture conditions, etc.

    These conditions, if allowed to go unchecked, can cause peeling of paints, spalling, formation of mildew, and efflorescence resulting in heavy maintenance costs. All porous masonry materials can experience these problems unless proper steps are taken. Due to its unique formulation, SEAL-IT Concrete Sealant can stop this type of wall sweating.
