Asked by: DJF89
I think so. I would suggest applying on dry surfaces. And I did it on the external wall under the grade 3 layers I'm amazed at the quality and application. Only time will tell for the waterproofing in the long run.

I want to use this in our bath/shower combo recessed cavity (all three walls and ceiling), on top of cement board. We plan to use a tub/shower surround (3 panels). The panels are only 58" high, so my question is can we paint overtop of this product?

Asked by: Blakeley
No. It is rubber, and on top of rough cement board. You are going to have to drywall (or drywall mud feather on top of the cement board) where it is visible above the surround panels for a smooth paintable surface.

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.

Mapelastic AquaDefense 3.79 L Dark Green Indoor/Outdoor Liquid Membrane is rated 4.6 out of 5 by 108.
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 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 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!
