It didn’t come with any instructions, only the msds. I don’t know if it’s applied full strength or mixed with water, so I applied full strength. I couldn’t find anything online that instructs how to use this product. I got this to use in my lake cottage because it gets so humid and there is always mold growth on any unfinished wood surfaces. I applied it to tile in the bathroom, wood planks on the bunk beds, and the window frame. So far it works but only time will tell. I’m hoping this keeps the mold from coming back on the wood. This can also be used on decks, roofs, shower curtains and liners. The brochure I found online mentions 10 year warranty but what does it mean? Once applied it lasts 10 years or what? I wish this company had more information on their brochure and a phone to contact them for questions.
