## Questions & Answers

**Q: Can it be used on a garage floor.**
A: Yes I suppose you could, although it stays tacky for quite a while.  We used it on our basement walls and about 2 inches of the floor where is met the walls.  We used about 6 coats.  It went on very easy.  I would use it on a floor if I were coating it with some other layer- seeing as it is tacky and even when dry it is still rubbery in a way that would not be easy to sweep.

**Q: Can you paint over this?  How about applying stucco finish over it?**
A: i,m not sure if you can paint over it,i didn,t have good luck with this product,applied over concrete wouldn,t stick,water leaked right through.

**Q: Can you use this for a liner of a stock tank that I turned into a swimming pool?  And does it feel like rubber on your skin?**
A: It's noy recommended for use in pools but we have had customers do it.  It does end up with somewhat of a rubbery feel.  If you do use it, keep in mind everything above the waterline must be top coated because it is UV sensitive.

**Q: does this product work well on brick? -- I have seepage in a basement that has brick wall (seepage is not to bad)**
A: Yes, it will adhere to brick just fine.
