## Questions & Answers

**Q: What is the difference between the MAX and the regular?**
A: The max is a slightly different white color. Different color than spray too. Which ever you choose stick with one or you will have multiple shades of white.

**Q: What's the best roller nap quarter inch or three eights to apply this with**
A: Product is super thick compared to regular paint. Shortest to no nap the best. Takes practice to get used to products viscosity. Try to apply thick and in one coat for best results. Product will self level as well and can also apply with trowel.

**Q: Will this work on a fiberglass swimming pool ?**
A: I'm not sure how long it will last because it is not reccomended for underfoot applications

**Q: Will this work to waterproof bottom of window sills?**
A: Yes. This will work well
