My last purchase was in September of 2000 and I couldn’t be more pleased with you products. I used the 429 S.T.U.F. in my automotive repair garage.
The garage was built with an 18 foot “grease pit” which I had coated with “429”. I had searched the internet for protective coatings when I came across www.seal-it.ca. I wanted to prevent automotive fluids from penetrating the concrete and also to make clean up any grease, oil, antifreeze, etc. easy and thorough. 429 S.T.U.F. has proven very durable and meets or exceeds your website claims. Nothing gets through 429.
I used Seal-It Concrete Sealant in 2000 also. This sealant was used on the driveway leading to my auto repair garage. Vehicles waiting for repair frequently leave oil spills. But on the treated concrete, when clean up is done soon after the spill, no stain remains. It is an excellent barrier to moisture.
