Review on 🔒 Seal It Green Xtreme Heavy-Duty Grout Sealer - Odorless Stain Block Technology. Water-Based, Non-Toxic & Zero VOC's. Seals & Protects. Easy Spray-On. Incredible Coverage of 100+ SF. Ideal for Indoor & Outdoor Use. by Frank Garahana

This sealant is amazing. No strong chemical odor like other sealants that require a gas mask to apply. It does NOT change the color of the tile, I can't believe it! It is very easy to apply and there is no mess. I sprayed it on a sponge and rubbed it into the tile. Does not smear and absorbs quickly within minutes. It definitely works. In the photo I applied it to a small section of the tile. You can see its beads in the bottom corner where the sealant is. Much better than other brands that require you to apply cloths and tape and these other brands darken the tiles and sometimes don't even work. This is life changing, I plan to do my whole house!
