Is it paintable?

Asked by: Spatt
You should not put paint on top of this product, it will just peel off. It's meant for being behind tile installations only.

Can this produce be used on Denseshield since I am using this product as a backer for a tiling? Second question, is it low odor? thanks

Asked by: lincoln123
It is low odor. I am not familiar with densesheild. This product is really good and when I used it on my concrete board I got it on plastic and some drywall and it adheres well on those as well.

can this be used with drywall?

Asked by: raul
I would not recommend using this on drywall. It is for grout only.

Can I apply mortar and tiles directly onto this?

Asked by: Mike1999
It was designed for exactly this purpose. Just remember to put some a few coats and if using a roller to apply, switch directing on each coat. For example, 1st coat is put on using a top to bottom stroke, 2nd coat would be left to right. This is to avoid missed spots especially when applied to a semi rough surface like cement backer boards.

Wondering if this can be used over existing drywall pryor to installing tiles

Asked by: cool_moss
Tehnically yes, preferably no. Water penetrating into gypsum wallboard should be avoided at all costs if possible, but this is technically spec'd for that type of application.

we would like to use this on a concrete, exterior porch which allows water to seep into our fruit cellar which is below the porch. what do we need to do if we would like to "cap" the porch with wood now for a different look?

Asked by: judij
Concrete by itself is not impervious to water and would need to be "waterproofed", but I would be hesitant to install anything wood over it that will be subjected to the elements over time. Have you thought about tile or stone veneer over the concrete if it is in good condition? A tile underlay like Schluter Ditra would prevent water penetration as well. There are several YouTube videos outlining the processes involved. Cheers.

3.79-L Liquid Membrane is rated 4.7 out of 5 by 69.
Rated 4 out of 5 by from Great product, but dark I originally tried a more well-known product that is red, you know which one it is. Surprisingly that product is to odiferous I had to stop using it. It literally takes your breath away. I then moved to Aquadefense. Still some odor, but oh so much better. It applied easily. Provides a nice dark green when dry. This however does complicate things when you try to put measuring marks on it. That would the only downside I saw to this product. I used it on the walls and the floor. A gallon does provide a respectable amount of coverage. Sorry that the uploader keeps turning my photos sideways.

Rated 5 out of 5 by from Works great Awesome product. The smell is not as bad as some competitors' products. It reminds me of perm chemicals, but not nearly as strong. It also dries very fast so the smell quickly becomes tolerable. The fast drying actually was a bit of a problem on the seams and corners, because I had to slap down a quick coat and get the fiberglass tape on before it started to dry. You will have maybe 30 seconds to do this from the first brush stroke before it starts to dry. Overall, it's a great product and I'm confident it will hold up for the life of my home. I still used a PVC liner underneath everything because I'm paranoid like that.

Rated 5 out of 5 by from Covers a lot of area My local Lowe's guy told me that a bucket only covers 33 sq. ft., it covers *so* much more. I applied four thick coats to our tub surround and cubbyhole, I have more than half a bucket left. First coat gets sucked into the concrete board, but following coats go on easier. Also, I was prepared for a noxious odor, but was pleasantly surprised that it wasn't that bad. The PVC glue was 10 times worse than this. Keep wet paper towels nearby, as it is very easy to clean up when wet, but very difficult when dry.

Rated 5 out of 5 by from This stuff is AMAZING I learned about this product on Youtube and thought I would give it a try as an extra barrier when re-tiling my shower since it's upstairs and I really didn't want any water leaks. It goes on very easy and covers quickly, It holds up fine when applying the mortar and tiling and doesn't show any signs of being scratched or the membrane damaged during this process. I live in Oregon and will probably use it for other weatherproofing as long as it's covered by another barrier if it's walked on or needs mechanical protection. The price is a little high but it goes a long way and covers really well so I think it's probably worth the cost. The only issue I had is the odor (like rubber smell) lingers for a few days so continual ventilation is needed.

Rated 5 out of 5 by from Defies belief. I tested this on a cardboard box by painting the inside in two coats and letting it dry for about a day and a half. The box held water for over a week and would have probably held longer but I got tired of a box of water on my back patio.

Rated 4 out of 5 by from Easy application We used Aqua Defense as an insurance, in our shower. We used the liner for the shower pan, up the walls 15". Then we used the Aqua defense to seal the seams of the cement boards. Using 4" roofing fiberglass mesh and aqua defense as the binder on seams and joins, instead of the mesh gray tape . We coated the entire stall, all the walls and seams twice including the dry mix on the floor. Making sure everything was dried completely before we did this. Lot of extra work, we are in our late fifties and don't plan to do the showers again. We hope this way the shower won't leak for the rest of our life. The only problem is when you first apply the Aqua Defense that thing has some heavy duty fumes, FAN AND OPEN WINDOWS is a must. Once it skins over the smell goes away in about two to three hours. This might be overkill but, we can sleep good knowing we did a good job. The time to rebuild and expand the shower was about five days. Good luck with your rebuilds done DIY. You got two good and helpful employees there, Moke, and Jeff. Keep them around!

Rated 5 out of 5 by from Easy to use and recommend Purchased this to add another water barrier while installing a custom made shower. There are fumes associated with it but not overpowering with an open window. Applying product is very easy. Rolled on walls just like paint. First coat took an hour to fully dry and second coat close to two hours. Coats very well and gives reassurance to water penetration.

Rated 5 out of 5 by from Works Great Easy to apply and fast waterproofing system. Even a novice can waterproof a bathroom or floor with this product.
