DIY Waterproofing Tub Shower Walls - Mapei AquaDefense (Mudroom & Bathroom: Episode 2)

Mudroom & Bathroom Episode 2: DIY Waterproofing Tub Shower Walls - Today I am waterproofing the bathtub shower in the mudroom bathroom. I am using Mapei Aquadefense and XFasten Fiberglass Membrane Fabric Tape. Before waterproofing, I taped and mudded (with modified thin-set) the joints of the cement board. All the studs around the shower were furred out with ¼” strips to allow me to install the cement board over (in front of) the bathtub flange. Then I caulked where the bathtub meets the cement board and where the bathtub meets the Ditra floor underlayment. I then applied the fabric tape embedded in Aquadefense on all the cement board joints and corners. After all the joints were done, I rolled two coats of the Aquadefense on the cement board.
This is a DIY project. I am not a professional!!!!

Love seeing women doing things like this, gives me hope that I can do it also. Thanks girl!!!

[@CountryGirlLiving]

You can! There are so many good video tutorials out there. Just watch a few of them and then give it a shot.

What a joy to see another capable woman! Most women doing DIY are such airheads. You make me proud, gal! Also very glad to see this MAPEI product. I did not know they made a waterproof sealant paint.
MAPEI is an Italian company. I love their Polymer for Thinset Mortar and Grout Maximizer sealant for grout that rubberizes both and ensures no cracking, no water leaks which is especially good for an RV application. I have to do my RV bathroom and here comes MAPEI to the rescue again! None of the tiles I installed have ever popped out of my RV despite the vibrations.

Very cool seeing a woman that’s handy doing this. I’m currently redoing my bathroom and at the same point you are at. The only thing I did different was putting the cement board on top of the tub lip instead of shimming all the 2x4s. I fiber tapped and cemented the space at the bottom. This way my cement board meets up evenly with the sheet rock.

[@juancastellanos4598]

Never sit backer board directly on bath rather on lip to prevent durock from getting wet , tile then goes on bath minus grout line to caulk

[@emilyemily1308]

It appears to be 1/4 off the tub and thus the sealant was pushed into that seam. Looked like it was done right to me.

Good job 👍

Thank you for making this and sharing! You're awesome!

Thank you!

[@brandont9916]

I’m not 100% sure the membrane material for the seams is required with this product. I’m sure it wouldn’t hurt anything though.

[@dwsolberg]

Love this. Awesome job and good filming.

[@CountryGirlLiving]

Thanks!

[@johng9562]

Absolutely excellent work.

[@BathroomRemodelingTeacher]

Nice 👍

[@gbsk12]

Where do you get the fabric?

[@paulstephens9274]

What did you first use filling joints

[@RandomUser1668]

Nice job! I wish my wife could have done it for us XD. Question: is necessary to put fabric tape over waterproofing layer?

[@CountryGirlLiving]

I am sure there are several different ways to do it. After researching, this is the method I settled on.

[@nonamuss9991]

Can the liquid waterproofing cure properly underneath the fabric tape?

[@vanessap8717]

Hi, I’m gonna do this on Monday. Did the aqua defender stick well to the silicone? I’m debating between silicone and polyurethane sealant for my wall to shower flange gap.

[@CountryGirlLiving]

It will not stick to silicone. The Lexel caulk that I used isn't silicone. Honestly I am not sure what it is, but it is paintable, and the waterproofing did stick to it. Hope that helps.

[@vanessap8717]

@@CountryGirlLiving oh ok, good to know. I used a poly and it all went well. LePage 2 in 1 seal and bond for any Canadians watching:)

[@PeaceAndMeditation]

Did you use both of those buckets of the Mapei for that shower?

[@CountryGirlLiving]

I think I used one and a half. It has been about two years, so I can't remember exactly.

[@cemmusabak]

No primer before Aquadefense?

[@vanessap8717]

I don’t believe it calls for a primer, redguard does though I think.
