Thank You for taking your time to teach the right way.I am a 60 y.old female trying to put a tub or shower pan in a single wide mobile home.I have fiberglassed many tubs built in ,it’s mostly the drains.You are a true professional. I am not Abel to find a metal 54” x 27” tub to replace the one a person took out and there’s copper waterlines right on the floor.If you have any ideas please let me know.Mom is 83 and on home dialysis,No One will take time to tell me the stuff you have again thank you,Red Guard is going to be a must.

To anyone saying that sheetrock is not adequate for a shower . For one its water resistant board he was using then applying redgaurd in 3 coats its completely waterproofed . So what exactly is the difference in a waterproof board you buy. Once you have a complete 100% waterproof rubber membrane over your surface, and the motor tile then grout and sealer is applied correctly. There will never be a issue of there being sheetrock the only way the tile will fail is, failure to maintain it and seal it correctly which most people dont . So this man is a professional and obviously has a good reputation and knows this is a good application probably because hes done more than most of the people on here commenting on it being wrong or a fail . I dont think you would be the guy getting calls to come fix the tile job we just had done because you do it wrong . Just saying .

i use hardibacker because it is a cementous product, Redgard says its meant for cementous surfaces. always read entire label.. :)

Hey Great video and lot's of information here.. I'm in the middle of a bathroom renovation and was wondering if the following steps I'm about to take are correct? (Tub and drywall is installed and Greenboard is installed down to tub lip). Would the following steps be correct? - Use 100% silicone adhesive in the seams and corners, including the shower niche - Use 100% silicone in gap between the tub and greenboard - Use fiber/mesh tape on all seams and corners including where drywall and tub meets - Use hot mud on all corners and seams and screw holes (but not where tub lip meets green board). - Redgard two full coats on flat surfaces and three in the corners, including 3 coats in corners of the shower niche. **Also I noticed a bow or two on the walls where the drywall dips into the middle/bottom of the wall which may cause the 6x12 tile 'not to clear' the tub lip (Only noticed once the drywall was fastened down tightly).Is there any way to skim those dips with hot mud and still have the Red guard stick to it or would I instead use modified thinset or something similar?** Thanks for your help!

Can you tell me what year cement board was made. My home was built in 1962 and they only used dry wall in the tub and shower area. I got the house in 1995 and my hand went through the wall in the shower. Water had gotten behind the tile and ate out the dry wall. Had to install cement board to fix it. Great video.

[@jamesthompson8778]

Good video. Thanks. I just finished backer board...moving on to mesh and covering screwheads, then red guard...

[@TONY-nl6yv]

Red quard great product . I actually did my own test 2 coats on a sneaker cardboard box. Filled up with water left it on my kitchen counter top for days never went through cardboard. That convinced me that it works. As far As me yes all my bathroom s I do use wonderboard or backerboard. But that was the way old timer teach me. As far as green board inside shower if it has red quard on it I don't see a problem. This stuff is great and it water proof . I be done foundations with sealing window leaks with it . I would see why it wouldn't work on drywall when it worked in a cardboard shoe box for days . Great video I enjoy watching . On all my job s all I do is renovate bathrooms n kitchen under all my tiles there's red quard . Great vid

Did my first bathroom following your tapes. I made couple of mistakes.Didn't level the sub floor and even with quick pitch it sloped. Tried to level ti again and hope doing thin set thick will give me the slope I need. My other issue was redgard membrane tape.

[@1erat]

Thank you for your quick response! I appreciate your videos and respect your opinion, as everything you say seems to make good sense. I am on a concrete slab and was planning on doing my pre-slope and pan all in one shot. I was going to slope from about 2 to 2-1/2” at the furthest wall to about 1-1/2” at the drain, cementing right over the bolted ring, allowing only enough of the edge of the drain to accommodate the tile and thin set. Then paint everything with several coats of redgard, including the outside edge of the drain and filling the basin with water over night to test. I intend to do the Durock seams, as well as the seat seams with fiberglass waterproof tape, lined on both sides with redgard. Do you think I also need to thin set these joints first? Thanks so much for your help.

[@kpriemer4]

I kept the cement board above the shower pan like you have said and I have put two coats of redgard on everything so far but the redgard doesn't seem to stick very well to the shower pan liner in that gap between the walls and the shower pan floor. Do I just need more coats of redgard? Or how do I fix that and make sure it's waterproof?

[@StarrTile]

I screed out thinset on mortar bed at the gap area as well as around drain prior to redgarding...I find redgard sticks to thinset better than mortar

[@curtiscole8213]

There are a lot of nay sayers out there about using this product. I'm currently remodeling and installing a tiled shower. I used cement board only because I wanted a more solid structure. I bought a pail of Redguard for $98. It's a small price to pay for ease of mind after tiles go on. What's the sense of cutting corners for something as small as a shower? Glad I stumbled across you vid. Thanks

I think it proves / disproves many myths or misunderstandings how a product can be used in a variety of ways, applications

[@eviltrain24]

That mesh tape is not a redundancy. Per the Redguard manufacturer's website installation instructions, installer must apply tape at seams and corners and apply a layer of reguard over the seams prior to general application over the whole surface. I forget if one coat is adequate but the recommendations outline in detail that the final dried redguard product needs to be so many mils thick and within a range. Too thin, and potential water barrier failure can occur. Too thick and the mortar may not stick properly to the redguard.

[@grega.5498]

Why do you need to put cement over the screws if you’re going to cover them w redgard? Is it just extra redundancy?

[@ghostghost6268]

Hi we are remodeling our bathroom, we have a fiberglass tub with the walls which leaves us waterproofing the shower surround only.its framed out, so we just need to install the geeanboard then paint? This is the first remodel we have done. is the green board like installing sheetrock? I mean you have to tape it mud it sand it then paint it? Correct? Any help is greatly appreciated! Thank you in advance!

[@StarrTile]

Greenboard is gypsum ( sheetrock ) with a chemical on it that resists mold/mildew. Because you'll be Redgarding it then I don't think it matters anyway, but I feel better about using it. I mud in the seams & recessed screw heads, but taping is up to you...if you tape then best to use fiberglass self sticking tape. The point is to fill any voids, let dry & waterproof, then tile.

[@kevinrenn9123]

In preparation for a remodel, I have been watching a bunch of videos on waterproofing a shower but still have one question no one has addressed.

[@chrisegglesden5192]

Custom building products does not approve red gard for use on green board. They only recommend using it on hardi at a 4-1 mix ( 4 parts water- 1 part red gard) as the primer coat. Hardi is thirsty and has to be primed first, and then an additional coat or 2 of red gard. Also apparently green board does not pass code for shower or tub walls anymore, at least not in KY.

[@SVETOGOR1]

Please tell me the best mold proof compound to cover the gaps between wall's tiles and finishing? thanks!

[@StarrTile]

Mold only grows with air/moisture...if you introduce no moisture then you're good. In the tub enclosure I use sheetrock mud, in a shower I use thinset.

[@SVETOGOR1]

StarrTile "In the tub enclosure I use sheetrock mud, in a shower I use thinset." why not use sheetrock or thinset for both? how one better than another? I guess thinset better as anti mold? there are alot of moisture in my bathroom (humid weather)!)

[@StarrTile]

You can do what you like, but I use the material match...greenboard in a tub, begets mud, backerboard in shower begets thinset...either way you waterproof it so doesn't matter in the end

I've come across this stuff when tiling showers also know as tanking when it is dryed out sometimes you can peel it off like wallpaper and a few times I have I found it very dodgy to tile onto I would never use it myself a good sand &cement wall and waterproof tile adhesive you will never have a problem

[@StarrTile]

And exactly how would it be dodgy? If you haven't ever used it then you would not know how durable it is, taking it off as you have mentioned as a whole whole different ball of wax all together.... your method works also but is antiquated, you should work smarter and not harder

[@kilts4u2]

I was wondering about that greenboard. While it is moisture proof for painting, I've seen quite a few tile tub surrounds crumble with that medium. Why not just avoid it altogether?

[@StarrTile]

Extremely rare to have gypsum crumble, when it does it's due to operator malfunction...no waterproofing, grout too runny or too thin, no grout additive, poor homeowner maintenance, etc...the backer is irrelevant if proper installation is lacking.

[@kilts4u2]

While it may be rare for gypsum to crumble, even with waterproofing prep, why use it to start with when concrete backing board and Hardibacker board are available? I read the comments from Custom about not recommended application of RedGard over greenboard. That's my point. I spent 40 years in the remodeling/building business. All in Atlanta--retiring 7 yrs ago. Did a lot of shower pan replacements for insurance repair companies. That's where my experience in observing bad construction comes from. . as I tore out quite a few bad ones. Agreed, waterproofing is essential before installing tile. The industry and its products has come a long way since I started out.

[@StarrTile]

Yes I allowed custom building products to post that comment as they are the experts on their product. But Denshield is gypsum with waterproofer on it so using hardi or durock isn't the point, it's the water proofing. So while cbp doesn't think it's a good idea on sheetrock, I've used it for a dozen years without any issues.

[@garygano2719]

What is your experience using Red Guard over greenboard when the tile installation does not go all the way to the ceiling? Will the Red Guard coating present an issue when painting the section of the wall above the tile line? Or should I ignore the Red Guard altogether and just concentrate on using a good paint when covering the exposed greenboard near the ceiling?

[@StarrTile]

You can skim coat sheetrock mud onto any excess redgard

[@thomascurtin9714]

I"m a DIYer renovating two bathrooms (common wall re complex plumbing) simultaneously, and the job involves RedGuard application and a hyper-concerned wife. So, for all my research and YT video review, I've found that one can RedGuard wallboard (in my case, the untiled ceiling within a shower/bath area) and subsequently paint it as long as a quality primer is the first pre-paint application. It's arguably a crap-ton of overkill, but the wife's anxiety is mitigated. For me, it was a rational/reasonable accommodation.

If greenboard gets wet, it will get soggy and attract mold/mildew. There is no way to get it wet using a topical membrane, so it's a moot issue what the backer is.

[@amomentwithanimals7429]

I find it odd that you know not to use mastic in a shower (a lot of tile guys don't know that) yet your using green board in a shower. Green board is for bathroom walls but not showers, it's only a moisture protection. I used only durock. Reason being is , even if you're waterproofing the shower,if there is a leak in the pipes In the future then the entire shower would possibly have to be removed and replaced rather than just fixing the pipe and a hole in the drywall from the other side of the wall.

[@StarrTile]

Yes I suppose anything in life could occur, leaks of pipes inside of the wall would be extremely rare and rectified rather quickly...but assuming it COULD happen in a year or 20 years down the road isn't something I'm thinking about EXCEPT adding in an access panel on the back wall which I do whenever possible.

Not true, drywall is throughout your whole house & doesn't get "soft". Now if it gets wet, that's another issue. But Redgard or any other topical membrane insures it'll never happen. I could build a shower out of 1/2'' cardboard and waterproof it and it'll last as long as Hardi.

[@GilBatesLovesyou]

I don't know if you still use Greenboard or not for showers, but one thing I thought about if you were to use it again is for seams and corners and screwholes, instead of using all purpose taping mud, use a hot mud like Durabond 90 or Easy Sand. Hot muds are essentially plaster and don't break with water contact, whereas normal taping mud turns to mush again. Plus in general they're stronger and less likely to crack, you can mix them to your own consistency you like like thinset, basically everything about them is better except for convenience. In my own test, green board breaks down outside after 2-3 months, but I've had a Hardie sheet outdoors for over 3 years and it's been fine. So I still think cement boards are better, but strangely in UK "tanking" over drywall is 100% approved and endorsed, as in, applying liquid rubber wateproofing and tape. I still feel the $20-30 or so extra material cost for cement boards for a tub surround is worth it, though.

[@birisutilemarble]

I will never install tile on drywall no meter how much you water proof dose walls .. that’s just me 👌 I always use Cement Board ( Durack brand ) or HardieBacker 👍

[@StarrTile]

If you use Kerdi Schluter or any waterproofer then the backer does not matter, even Kerdi Schluter allows for sheetrock behind their product, if you are only using a cement board then I hate to tell you that it is porous and will Wick water... but of course I'm sure you know that, same as I know my products

I'm also a little leery about Redgards what looks to be foam floor piece as I would think a heavier person would crush the foam slightly and ruin the tile job on the floor. Thanks in advance.

[@StarrTile]

I have not ever used the foam pieces.. just like you, I do not trust them. And yes, Custom Building Products who manufacturers it says that it can be used as a pan liner... although I would never take the chance, because I have customers to answer to

hi there, i live in upstate ny, companies around here wont waterproof your shower stalls before tiling, not all the companies, also i know many mexicants who dont know what redgard, or other waterproof solutions are, kerdi or waterproof boards, i do use redgard every time at my tile jobs, it is cheap and works well, it is just sad many people dont waterproof before tiling, they believe tile and cement board are enough, great video

The home owner should never under any circumstance ski this tiller to use wonder board!! Ohh but he use red gard so what !!!!pendejo!

[@joaquinsuarez6090]

No need to mention contractors or workers nationalities. Very few contractors waterproof walls before tiling and don't even know they should and if they do it will charge you around $500 or more extra for an extra day will take them to apply 2 or 3 coats, most of them are lazy and want easy quick money. I am buying it and applying it before the contractor starts installing the tiles and I am sure doesn't have a clue waterproofing exists and is highly recommended.

[@famousforever8556]

Just to help out the "You're not supposed to use it on drywall, even Redgard says so" story tellers: "Redgard is a liquid waterproofing and crack-prevention material that dries to a flexible membrane. For interior and exterior use, Redgard may be applied to surfaces such as concrete, exterior-grade plywood, decks and gypsum-based materials. It also functions as a moisture barrier beneath all kinds of floor coverings. Redgard comes in 1- and 3.5-gallon sizes and may be applied with a roller, trowel or airless sprayer."

[@angry-white-men]

Sounds good, I'll use plywood for my shower walls then instead of drywall

[@StarrTile]

@@angry-white-men or even half inch cardboard if you could find some... it's funny you mention plywood though, I had an inflatable boat years ago and I did not like the rigidity of the hull so I cut out a huge piece of 3/4 plywood for my hull and painted the entire thing three times with redgard, proved to be waterproof👍

[@gr8gracefreight986]

Isn’t drywall a gypsum based material. They call em gyprock in Australia.

[@Damien59]

Drywall is a panel made of gypsum plaster sandwiched between thick paper. It is used in the construction of interior walls and ceilings as a replacement for the traditional lath and plaster method. Other names for drywall panels are plasterboard, wallboard, gypsum board, gyprock, and Sheetrock.

[@VVVV-yr4tp]

Why do you use thinset or mud underneath the redgard. I would imagine the redgard would sufficiently cover all screw holes and such, or not? I love everything I've read about redgard,

It wouldn't matter if you use 1/2 in cardboard or 8 in cinder block, you're waterproofing surface so therefore it's irrelevant what the backer board is.... but of course you probably don't waterproof anything so your failures may be about missing that key thing.

They slop it on the tub ..when that dries it's a nightmare...breathing it sucks. So...HERE IS A MIND BLOWER... And I'm the only one that I know that does it. And when other tile guys see it they go..wow.. how I have not thought about it...ready?????? Roll the waterproofer on outside on saw benches.. then install the boards.

I recently bought a house with two baths. One bath has a stand up shower the other has a tub with tile halfway up the wall, greenboard and wall paper on the rest.

Eventually we're going to remodel the whole bathroom and I hate to go through the time an expense now of tiling when I'm going to be placing a new shower in a couple of years.

I built the pre-slope out of quikrete mortar mix (even though I know your opinion of those) Installed the Oatey liner per your videos and as you say some common sense. I have installed the mortar bed ( although I would have liked to done a little better job sloping/leveling) Is there a product you recommend to tidy up that level and slope? I did the best I could. My next step is walls (right?) doing the proper gap at the bottom. Then after that comes my question. Lots out there about redgard... don't use a premix thinset for the tile (which I love) I hate mixing when I can buy the right consistency ready to use... only the stuff you mix yourself will provide the bond needed for the tile... don't coat the motarbed... coat everything... only coat the seams on the walls .... coat the entire walls... thoughts please....thanks !

[@glockshooter7089]

Greetings again... Love your vids... question on wall board: I noticed in this vid that you are applying tile over gypsum instead of durock. I get that nobody is walking on it and flexing shouldn't be a problem like on a floor. Many other tilers I see using durock on walls. Is it your opinion that durock is overkill on walls and your typical wall board should suffice?

[@StarrTile]

+Glock Shooter Thanks for the question. First off, this is a tub/shower combo so a "hardier" wallboard isn't as important...secondly it has Redgard on it so the wallboard make-up doesn't matter. My feelings & belief is that on full showers the same logic holds true, if it's Hardibacker, Durock, Wonderboard, it STILL should be waterproofed so for that reason the make-up of board doesn't matter. I would however entertain an opposing opinion ( backed up with logic ) from other tile guys.

[@glockshooter7089]

+StarrTile I agree with your assessment. I haven't asked any other tile vid guys why they use it. Maybe I should. My thought on the matter is that my bathroom floor will need the support of the durock I'm sure as you need the added support to prevent floor flex from popping up tiles. I don't see this happening much on walls, even if you occasionally lean on them. I'm certain there is not much impact movement on shower walls. Just my two cents ... thanks for the reply. Just trying to learn before I attempt to make a mess of my master bath.

[@StarrTile]

Floor is different animal, of course I use proper board on them to prevent issues. Walls I'm never too concerned with, it's EXTREMELY rare I see walls falling apart/rotting/water...vertical tile & grout dry quickly. The bowing or flex as you call it happens more with Durock and Wonderboard than gypsum, greenboard is more rigid between studs and coated with anti mold chemicals.

[@themrmoy40]

Your right, your instinct is telling you different you should use cement board then use red gard, don't do a double water proof. By putting plastic or felt on the studs . Just do one .

[@skipcercelletta6659]

green board is not for tile, EVER, it's a cheap way of doing things 1

[@StarrTile]

You are 100% incorrect. Not only is it used in bath shower combos all the time, but a topical membrane like Redgard makes the backerboard a moot and irrelevant issue

[@ozzstars_cars]

Green board in any wet area where tile is used is against code where I live. A cementitious board must be used.

skip cercelletta You have heard correctly. BUT... Things have changed over the last 15yrs. It can be a hard sell to experienced contractors (who think they know it all) but current waterproofing methods alow us to use drywall in showers. It's a common practice, yielding much better results; both in mold prevention, and MUCH longer warrantys.

[@snowblind5151]

It's all in application of product.Like screws penetrating paper .I remodel grocery stores , the green board behind the FRP totally saturated with moisture and mold . They used tubed glue in swirls not covering the green board. This is in the butcher area ,we usually go four feet up with durarcock then green board . But we have just used green board as long as you cover every ares with the correct adhesive works same with tile .

I'm preparing to tile my bath alcove and have new DenShield installed and would like to know what did you fill in the seams/gaps underneath the tape and between the tub and wallboard? thinset? silicone caulk? first home and first attempt so I am trying to gather as much info as possible

[@StarrTile]

+romejas Denshield is waterproof, but I still redgard it, corners, screw heads, etc., however I don't always use tape since redgard is liquid rubber so "cracking" in corners is a moot issue. Caulking ( in my opinion ) is not needed either. Having said that, you can overkill if you like, denshield, caulk, tape, redgard with 3 coats, etc....but do the tile & grout right and seal the grout...that's what keeps water off you wall to start with.

[@romejas]

+StarrTile thank you for the advice!.. I was wondering if you have a brand of grout and sealer that you recommend for a shower bath alcove? Installing 6 x 6 porcelain tiles probably with 1/8 spacer

[@StarrTile]

For me grout is grout, but Lowes brand seems to repel water when trying to mix it...then use an admix instead of water to make it stronger, then seal with just about any grout sealer after waiting a few days. OR use an epoxy grout, nothing will get in that & no sealing needed.
