Redgard Waterproofing | Troweling Vs Rolling | Tile Tub Surround

[@jayb9543]

I am so glad I came across your page, I'm a big DIYer and have learn a lot more than I thought I knew about various techniques for building out, water proofing, tiling etc, thank you so much for all the work you and your wife are doing and please keep the videos coming!

[@andrewlupton2120]

As a DIYer doing a 2 wall basement shower for the first time, I used Kerdi board (Schluter) and found it really simple and only a bit more in price that the Red Guard/cement board. Factor in mess, drying times, fumes, etc and I can't see why you wouldn't do with Schluter. The boards are light, can cut with a knife, they are waterproof (of course you have to cover seams and screw penetrations). When I demo the upstairs shower I'm going to use Kerdi board again and this video (which was great by the way) just clarified that decision for me.

[@BathroomRemodelingTeacher]

😊 exactly 👍 way easier ways to go these days. The fumes are insane with Redgard 😆 thx

[@richeyrich2203]

[@NotRiansLuke]

This is a GREAT video! I wish I'd found this a month ago, before I started ripping walls out. Still hanging cement board (which I'd have done slightly differently had I found your video sooner), but this is great info for when I get to the Redgard stage. In our master bathroom. Ugh, lol. Luckily I used Hardie's upgraded waterproof board for the entire long wall, so only need Regard on the two short walls (and over the screws on the Hardie waterproof board). Anyway, this deserves a lot more views and likes -- you have one of the best tub surround videos out there, and I have watched plenty. Thanks for this!

[@Cello69.]

DIYer here. Redgard is an amazing product. I use it all the time. Turn on the vent and stick a fan in the room.

[@map2hvn808]

I rolled three coats of Regard in a bathroom job about 7 years ago. No problems so far, works great. But it can kill some brain cells. Were a respirator.

[@hightide-mcknotts]

I'm also not a fan of RedGaurd - I prefer to use Hydro-Ban - Much easier - less time consuming process (application and drying time) and almost odorless - Plus I believe its a better waterproofing liquid membrane. I actually prefer to use waterproof Foam board and just seal the joints and screw/plates with Waterproof sealant, and not have to cover the whole wall with a waterproof membrane. I use a 12" wide waterproofing of Hydro Ban on the transition from Wallboard to drywall areas. Thank you for your excellent and very informative and honest opinions videos!

[@hemidesign]

You're correct, Hydroban and AquaDefense are the best for waterproofing! Ardex8+9 and RedGard are pure junk products!

[@Skooterboy0610]

Doesnt the cement board need to be 3/4" above the tub deck? Wont there be weeping issues when water eventually penetrates the tile and grout from the deck?

[@erichutchinson4831]

I see a lot of hack tilers on youtube. When someone starts quoting TCNA, NTCA, ANSI standards and recommends following manufactures recommendations, they have my attention.

[@StormyTuesday5108]

Nice. My shower started falling down after 12 years. Taking it apart. Mistakes found: mold due to no waterproofing, used regular sheetrock on the shower, no blocking and no framing on one wall (still trying to figure this part out)

[@ABobsLife]

I know i'm late to the party. But excellent video. Been watching your channel alot. I'm working on my MB remodel and your channel has been a Great Tool. Thank's.

[@Marbind]

You need to prime a cement board with a diluted mix of redguard + water. Text from the redguard instructions. Prime all surfaces to receive RedGard® with properly applied manufacturer's sealer or with a primer coat of RedGard®, consisting of 1 part RedGard®, diluted with 4 parts clean, cool water. In a clean pail, mix at low speed to obtain a lump-free solution.

[@loukovanda5539]

You spilled at least a gallon of red guard in the tub lol. Glad I found this for a good reference before I used this product. Thanks.

[@AnthonyClark177]

Thanks for the clip. I saw some contractors who strongly suggested putting thin-set on cement board directly without the waterproof membrane.

[@quartqwertbudisgood]

Wild, you can do that and if the tile and grout are sealed it might last upwards of 10 years of nothing ever gets cracked, I just pulled apart a tub surround that was glued onto regular drywall with no problems (no shower in tub)

[@Gibran1517]

40 years ago there was no cement board or water proofing. My old house has tile directly on drywall. Its fine. Everything is overkill today because of lawyers and liability.

[@connicrow9463]

​@@Gibran1517Yes as I kid I helped my uncle retile our shower 30 years ago in '95, w green board and paint primer. It's been bulletproof w so many rental families daily use. The new water proofing products are available for those with money, or for diy folks to reduce margins of error, and also make sure an expensive custom shower will last a very long time.

Do I need red guard if I use the red cement board that is supposed to be water proof

[@repp181]

very helpfull! I'm enjoying your videos a lot these days

wouldnt it dry faster and maybe finish faster if you did more thinner coats to get the same coverage? they claim it drys in 90 min if u roll it i imagine.

[@trisa9625]

hey bud qs how come it says the max pro is recommended for window exterior and siding, not recommended for bathroom? can I still use it for sealing my bathroom cement board

[@julyd.9201]

I don't like when you install the bathtub first and then you tile the floor up to the tub.Then the tub is below the tile. When I do my bathroom I want to tile the floor first and the tub will sit on the tile floor. Is that the wrong way to do it. Back in the day I used to see the tube sitting on top of the tile

[@kirkstaggs9773]

Is it important to use the seem tape for the wall to ceiling corner/transition?

[@BonBon770]

I barely made it through the whole video, the reason it's still wet the next day is because you're putting it on too thick. I understand the jug says what it says, but putting it on in thin Coats 5 Coats with a roller in one day, the 2nd day after the 1st day you hang all the concrete board tape and see all the joints with alkali resistant concrete board, seam tape and thin set like you mentioned. Let it dry and then put 5 Coats on the next day with a fan with a respirator. And I'm using exactly the same amount you are. it should end up being credit card thickness so you're doing it in 2 days and I'm doing it in 2 days, but I'm doing it with a roller, so it's the same, im just using ardex s1k..... Also different municipalities call for different distances on concrete board screws. Where I am it's six inches on edge , Is and eight in the field...... Good video man!

[@BathroomRemodelingTeacher]

Guess only difference is 2nd day I’m done in 45 minutes verses messing around every hour to apply more. If I had other things to do, I agree rolling is easier. But this is the last time for me anyways 😆

[@splanzza]

Great vid by BRT. Finally to see someone do it this way. I have done my first bathroom loooong time ago the same way and relied on common sense. Now watching you do this Steve I got the idea and wonder what if we redguard cement boards prior to installing them onto walls? 👀 Would be much easier handling the trowel on a flat (sawhorse plywood table) or even on the floor and definitely way less messier. Then it would left only to embed the tape over the seams and corners. Hmmmmh And for the smell, if I remember correctly it was strong ammonia based odor that after two hours working in confined space definitely gets to you. Never used hydroban. Does that smell strong as well?

[@BathroomRemodelingTeacher]

That’s not a bad idea at all. Less work than in the field. I’d still go with a foam board any day 😆

[@splanzza]

@@BathroomRemodelingTeacher Hahaha, of course. Foam board is superior in so many ways. Great work. Saw a finished Barbie & Ken bathroom on insta. Looks dope. 👍💪

How come you didn't use "green/purple board" drywall in bathroom? I am asking before i finish the video so you may have answered.

Do you have to plan using furring strips when you set the toilet flang? I assume this could be a problem if you are doing a remodel where the flange is already installed?

[@biblgrl6563]

Is it necessary to use the mesh tape with the goboard sealant because you're using durock? Goboard install only needs to just use the goboard sealant with no mesh tape.

Go go board, no. Simply use sealant 👍

As a virgin bathroom re-modeller, and trying to balance budget vs idiot-proof, I'm reluctant to try using Schluter simply because I expect to screw up. RedGuard seems easy enough for us newb's but is Ardex or HydroBan just as forgiving? Budget wise, you made a great point about being budget comparable.

[@danielwagoner]

I’m currently doing a full house remodel that includes two bathrooms where I’m building custom showers. I’m definitely using cement board and a liquid membrane. You mentioned a couple other products and I know there is also mapai aqua defense. Of all those products, which is the best and/or easiest to work with?

[@BathroomRemodelingTeacher]

Easiest is hydroban. Best I’d say is Ardex 8+9. It’s like a rhino liner.

[@cjg7346]

[@margaretbear]

I agree about the smell. It's awful. I have never used Redgard as my primary waterproofing method. I use it as extra protection in corners, around windows, anywhere i think might need just that extra bit of insurance - especially with Schluter since i don't trust their method of using thinset after watching some of Tile Coach's stuff. I trust the poly sealants much more. I may never buy anymore of it since i can get Hydroban locally now.

[@eunicom]

Love your trowel method and it’s friendlier to drywallers like myself. Would you know if this method can also be applied to other liquid membrane products like Hydroban or AquaDefense? And how do you clean your tools so you can transition to drywall? Just let the redguard dry and peel off?

[@BathroomRemodelingTeacher]

I feel aquadefense is pretty much the same consistency as Redgard. So wouldn’t be a bad idea to do it with that. Hydroban goes on thick. So normally not needed. But is helpful troweling the seams and corners

[@BathroomRemodelingTeacher]

To get the best cuts you've set up. Saw horses outside with a fan and check the wind and make sure the dust goes down wind. Or you can put a little bit of water on the board and it'll keep the dust down but cutting. With a grinder outside is still best for cutting concrete board. gives you the best edge most accurate.

You don't have to install cement board to build a waterproof shower, you can use moisture proof drywall and apply 2 coats of Hydroban or AquaDefense (avoid this crappy RedGard or Ardex 8+9) You're done and ready to tile!

Agree. 30 years ago I was 13, and helped my uncle re-tile the walls of our bath (which has a 60's cast iron tub still in near perfect shape). We used green sheetrock, and liquid nails tub surround sealant + mesh tape over the seams & corners; and then rolled on 3 coats of Zinsser paint primer (1 gallon) giving extra attention to the first 4 feet, before tiling. 3 decades later, after daily use by mulriple rental families -- it's been bullet proof. Not a single issue, and I feel it's easily good for another 2 decades.

Nothing wrong with this contractor's method of building a bath shower, which will likely outlast the homeowners lol.
