## Questions & Answers

**Q: Does it give a wet look?**
A: No, not a wet look on how I used it.  It was absorbed . . . at least it was into flagstone.  Other stones may be different

**Q: Does it give a wet look?**
A: no

**Q: How much coverage per gallon**
A: I believe it varies based on what type of tile and whether it is the first application. I had 3200 square feet of brushed and chiseled ivory travertine tile installed in my home. The installer had me order 6 of these bottles of sealer and there was about one half bottle left after they sealed the tile. The travertine tile is very rough and porous. I imagine a smoother tile would require less. Also, the installer told me that when I go to reseal the tile, I would only need about half as much.

**Q: Whats the difference between the heavy duty vs. regular bulletproof sealer?**
A: this is a very good product I do not know the regular bulletproof sealer product

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by B***T on February 11, 2018*

I bought 6 gallons of this product to seal the 3200 square feet of travertine flooring I had installed. I was afraid that 6 gallons would not be enough, but I ended up with a half gallon left over. The installers applied the sealer and they did not have any problems with it. As can be expected, there was a strong chemical smell as it dried and for a little while after. It was smelly, but not overwhelming and it went away after about a day. The sealer brought out the colors in the travertine without making the tile appear wet. I am happy with this product.

### ⭐⭐⭐⭐ Stone sealer for granite, marble, etc.
*by P***. on October 9, 2017*

Granite and Marble sealer works well

### ⭐⭐⭐⭐⭐ Ease of application
*by T***H on October 27, 2023*

I just sprayed it on the old brick walls so don't know yet about how well it will seal them but it was easy to spray and cleanup.
