Rated 4.5 out of 5 by 64 reviewers.
Rated 5 out of 5 by Easy to Apply Water Isolation Barrier Not much simpler than this to apply a water barrier for showers. Oh sure the fabric membranes are nice but are you really sure you have 100% adhesion? With Red Guard there is no question if you have a good attachment of the water barrier because it's painted on directly to the concrete board. I seal the seams with fiberglass tape and Red Guard for a perfect water barrier. For now I've only used it for bathroom tile jobs but will be trying it out on a tiled floor job next week. Want to have an isolation layer similar to what tile under layment membrane would do but for less time and money. Oh yeah, got to love the bubble gum pink when you first apply it but the results speak for themselves. July 22, 2014
Rated 5 out of 5 by Awesome Product - (also providing clarification on a wrongful 1 Star review by another customer) I have used REDGARD on walls and floors, had excellent results. Even after a year with only using 7/16" OSB on top of 3/4" subfloor, my tile is still flawless. No cracks, no issues, lot's of foot traffic. I also wanted to comment on a misleading review - 'Bill from Florida' gave this 1 star review "$675 Shot. No where on the instructions or website does it say "wait 28 days for new concrete to cure". So after 4 good days we put down the Redgard and now its peeling up. And Redgard says "you should have waited". How are you to know if you don't tell me" It is known by those in the construction industry as a rule of thumb to always "wait 28 days for new concrete to cure", before applying any type of sealant. In the manufacturers defense, concrete can cure much faster or slower depending in the mix and weather. If you are going to seal concrete, see what the manufacturer or mix plant says. REDGARD or any other manufacturer can not know your variables. December 18, 2013
Rated 5 out of 5 by Easy to use Simple to use. If you can use a brush and roller, this is the stuff for you. October 18, 2014
Rated 4 out of 5 by Smelly but easy to apply Product was extremely easy to apply. I applied it to 3/4" Concrete Board . Applied with a roller from top to bottom. let it dry (turns a slight reddish pink) and applied the second coat from left to right. When dried It turns red. After it dried I inspected the surfaces for air bubbles or gaps where it didn't cover completely and went over those areas again.... After That it was just Thinset and tile until done. The only downside to this product was the smell it puts off.. Make sure the room is well ventilated. After about 24 hours the smell is gone. October 15, 2013
Rated 5 out of 5 by Easy to work with Easy to work with. 4" paint roller works right inside the pail and spreads easy. coats pretty fast and dry's quick too depending on coating amount June 20, 2013
