Just wanted to let you know that I am impressed with the performance of your wood cleaning and sealing products.
The building in the pictures was built about 12 years ago. I used a pine tongue and groove, installed vertically, as siding. The siding was coated with a “urethane” product at that time.
The wall you see in the pictures is about 5 or 6 feet from our gravel back alley. Water lays in this alley near the building, and, over the years there has been a lot of water splashed on the wall, plus any rain.
In the pictures you can see 3 distinct bands of color, the top of the wall seems to have some of the urethane coating still hanging on, below that the wood is quite “bleached”. The bottom 4 feet or so is black from rot. I hadn’t decided what I was going to do to with the wall, but expected to either have to replace the pine or cover it with vinyl siding.
I would say after seeing what your products have done, I won’t have to do either.
