## Questions & Answers

**Q: Will this still allow efflorescence to come up in pavers? I don't want to trap efflorescence in the stones, but I want to protect them immediately.**
A: This product appears to meet its description, it's absorbed into to brick & nothing appears to go in or come out. It seals well. I've had it on the walls for one year. You're welcome.

**Q: Beyond sealing does LastiSeal bring out the color of my concrete pavers? Gloss??**
A: Very little gloss. I don't know if it will bring out the color of your pavers as I just on the  concrete garage floor and driveway.

**Q: does it have a gloss finish**
A: No. The intention of the sealer is penetrate into porous building materials (hence the word porous) without changing the look or friction of the surface.

**Q: Will this product turn white/cloudy when exposed to water?**
A: Not at all. It's a milky color in the bottle but it doesn't turn anything white that I applied it to. What I did notice was the mortar between the bricks feels differently when I run my finger across it. Little grains that used to rub off before don't now. And the water seems to run right off
