You might also like Wedi or KERDI-BOARDs because you don’t have to use RedGard on them (which can be stinky). I’d be happy to look at the shower and transition via email. I am in the same spot. Required fields are marked *. 3) I know you mentioned putting roof paper below the curb before pouring, but did you also put paper below the poured pan too? Dirk Haagenson Hope to learn! For a project like this, if you end up doing the concrete wrong you can bust it out with less than an hour of hammering with a sledgehammer or deadblow hammer. All the videos I have watched don’t use both, I just was curious if it was a good idea to use to water proof barriers instead of one. Are you going to do a glass door or just use a shower curtain? I’ve got some “make stuff with my hands” goals for the new year, but this is probably a little overly ambitious for me. Saw video some guy used acrylic latex primer before applying says works better. June 6, 2013, 10:05 pm. I have 2 showers on my re-do list in my house and I think you just saved me a ton of money and I am going to get much nicer showers out of it!! But how should I make the transition seamless and ready for paint? We just had to have someone reinstall 2 windows we tried to do ourselves. We used blue tape along the edge of the tub where it met up with cement board. I just like to go overboard sometimes since I’ve seen a lot of circumstances where water has completely destroyed walls or ceilings. We are wanting to tile over a concrete pad (26 years old) and have stained and then painted over the years. This will provide a nice 3/4″ slope to allow water to flow down into the drain. To create a uniform slope, use a ruler or level to draw a line all around the perimeter of the showerpan that is about 2.75″ off the floor. After researching, I noticed that the cement backer board is the preferred method, however, the builder put up blue board sheetrock. Next, run a bead of silicone caulk or specialized shower liner sealant under the cut edge of the shower liner at the cutout for the shower drain. Don’t get RedGard on the tub. The black material at the bottom is roofing paper – just to isolate the concrete from the plywood so the moisture from the wet concrete would not wick out into the floor. I just can’t grasp the concept no matter what videos I watch! And it’s information that I truly appreciate. I have already chalked the 5’ piece and end piece. I like using a semi-gloss sheen so that if there’s any moisture it will wipe off the wall. Well done. Two questions — one, it sounds like you’re installing this over a slab (I’m assuming a slab floor in a former carport); what if any are the implications of the weight of the concrete in other contexts? And the new space is 6″ higher than carport. The detailed video tutorials are super helpful and focus on getting professional results. The latter is feasible if the studs are bumped out using scrap plywood. My question, what about the concrete bottom of the shower? Which view is correct? You could either sand or float the area. I don’t want to go back to replace seams etc. Reasons? I’ve seen soaked drywall behind tile walls several times in my limited experience. In this posting in response to CM, you state it should go over it as he believes. Dan, Your email address will not be published. Then let that concrete cure, and add your Redguard, over all the concrete and extending right over the edge of the plastic. Are you saying to apply the RedGard to the corners and seams then embed the alkali resistant mesh tape? I literally just finished one in our rental and it looks great. So, you should be fine using any polymer modified mortar that meets those specific standards. The contractor will have to buy a 1 gallon bucket and follow the directions for your particular situation. I like the look of glass but have had a terrible time keeping it “clean” or keeping the calcium deposits off of it in every house I have had glass before? I think they look pretty nice – and you only need one in theory, where you join the final drain from your whole house, into the output to the street.. if you re-do everything else, that is. No membrane to back you up. Two, I’m hoping any future remodels I’m involved with will employ the principles of accessible design, which would lean toward no curb. Great article, However, I’m wondering why you didn’t mention priming the cement board? Put mortar additive to concrete and very top layer of concrete put some layer of mortar.while concrete is still wet to tight em together. 2) There are also some specialty drains by Schluter/Kerdi and Laticrete which are made to be used with liquid membrane, i.e. December 23, 2012, 10:09 am. The walls are all painted with eggshell paint. do you silicone the drain ring down to the tiles? Look into low cost and free homeowner workshops in your area.

Kerdi serves as a vapor barrier of sorts but no matter what you put up as a vapor barrier there will always be a certain amount of vapor that penetrates the tile and goes into the stud bay. It was a “luxury shower” built almost 20 years ago, but it didn’t even experience 20 years of constant use. My glass tile supplier recommends filling the corner voids with silicone in order to provide a good expansion joint for the glass. MMM, I had a couple of follow-up questions after reading this article 3 times over, as I’ve never poured concrete or tiled, but feel confident that I can give it a go! This is such a great method. So we added the cement board then RedGard and that was it. Note that for extra strength in this case, I put some large 4″ screws into the floor at each joint, and ran some steel reinforcing wire along the length of the form’s center, to create more tensile strength (and thus crack resistance) in the finished form. in favor of a tiled space. Really awesome. IMHO the biggest issue on showers like this is keeping the grout clean. This is a great site and thanks for providing all the steps to install tile.

And for this shower we only needed one gallon. I decided on to use hydro ban instead basically the same stuff but should I use the latter primer first? Unfortunately, we had someone install our bathtub and they put Wonderboard behind the bathtub, not floating it at all. I noticed the same on the wall waterproofing. Today we’re going to share how we made the cement panels completely waterproof using RedGard (1 gallon costs $50). IMO, the best option here is to continue the Redguard all the way up the walls (exactly as recommended by the manufacturer). Especially if you live in an area that gets extremely cold or hot. No waterproofing or cement board in sight. There is how-to’s regarding a divot method and these drains, but I was hoping to use your exact method…and drain. Do I need to use mesh tape for this transition? This took about 1 to 1.5 hours. Jeff, Thank you for the write up, it has been VERY helpful.

All seams should be sealed with alkalli resistant mesh and embedded in thinset mortar. Great info on your site! Thanks Adam for asking about the tile. Yep, complete tear out, walls tile floor etc… 😑. The thing is, the old method has not been updated to reflect a more recent invention: trowel-on waterproofing materials like Redguard and Aquaguard. You mention you isolate the contretemps from the plywood with the roofing paper. Others are not so good in my view. However the wife wants the walls painted now. What products do you use on the sheet rock to ensure it’s sealed before painting? I think your ‘old way’ diagram is wrong, the liner goes behind the cement board, and a 6 mil sheet of plastic is behind the cement board because it is still permeable enough that water will wick through it. We paid close attention to applying a good coat of RedGard to all the corners and spaces adjacent to the tub since these are the areas that water likes to penetrate the most. This goes right over the concrete, over the plastic edge of the drain, and up the walls a few feet.
