Which is the Best Waterproofing System for a Tub Shower

💥Waterproofing System Comparison💥
Its a question I get all the time, "Which is the best waterproofing method out there for a tile shower?"
It comes down to 3 main factors:
Availability (Can I pick it up now & get to work 😄)
Time of Installation (if you are a contractor, time is money)
Price/Budget
Foam board is no doubt the easiest & fastest system to install
Especially the sealant application type systems
Not all are price friendly though...
Kerdi board for instance can cost upwards of $80 a sheet!

Foam boards like WEDI can be quite costly too!

Hydro-Blok Foam Board is pretty much an identical type of product as WEDI

One of my favorite foam boards is Go Board - bit.ly/48gdL40
Readily available
Fast & Easy

Most sealant application type systems can be installed easily in a couple of hours 👊
Another popular method is sheet membranes like Schluter Kerdi
This method becomes very cost effective if you use drywall as a backer board 👍

GURU Membrane is a very similar membrane product
Biggest issue about membrane application is the mess.....Its not a very fun method to apply
Then you can't forget about a traditional method with cement board 👍
This has been a method used for decades
For a tutorial on installing cement board check out this section of the Home Office Bathroom Course - bit.ly/47iDBDX
Cement board is not waterproof on its own though
A liquid waterproofing must be applied to be waterproof
Ardex 8+9 is one of my favorite liquid membranes
Check out this section of the Basement Bathroom Course for tutorial on Ardex 8+9 - bit.ly/47iDBDX
Redgard is probably the most popular liquid membrane used over cement board
I would argue primarily for its availability

Thank God for this dude my own boss won't even show me any of these things he thinks I am going to take his work away

[@stephengranzeier5828]

You have the wrong boss.

[@garrettpatten6312]

Isn't that pathetic? I never understood that, the better & more knowledgable everyone around me is the easier the day goes.

[@ChristianErnst-bb4xg]

Fantastic video that not only goes over the options, but shows the install. Best video I’ve found thus far.

[@tracybrooks215]

I've tried topical and kerdi membrane and foam boards I prefer foam board over them all because light weight and no dust cutting the board

[@willyscreation]

Great video! Thank you for your experience

[@New_Czar]

Really good info 👍🏾

[@rezanyc]

Most people prefer the foam board for light weight and convenience, but that aside - which one is better? Foam boards or cements board with waterproofing membranes?

[@fittekowner]

What do you think of Densheild ? My tile contractor swears by it as it is wateroroof and cuts like sheetrock.

[@mqass7677]

Whats the white material you used for the 1st cement board clip? I'm doing my bathroom and decided cement board was the best choice and now wanna make sure its water proof besides jus sealing the seams..

[@RodrigoSilva-ys7zp]

Sikaflex from Sika is the best selant

[@billsnyder6945]

I haven’t seen you install a tile redi system. Have you done any and what are you thoughts? They seem bulletproof where it counts.

[@shesuniversal38]

My tile goes up from the tub, to 41". If I want to tile all the way to the ceiling, do I need to bust out the upper walls and apply insulation and cement board?

[@copiapoa]

Which method lasts the longest?

[@royalblood2405]

Whichever was installed correctly according to manufacturer recommended methods

[@copiapoa]

@@royalblood2405 that goes without saying

[@matthewrick]

Red guard gets a lot of hate. Have you compared it with the other big membrane products like hydro ban or aqua defense? Do you have an opinion on the various membrane systems? For a novice like myself they seem affordable and forgiving, but I could be overlooking a cheaper board system.

[@BathroomRemodelingTeacher]

I have not created a video on the differences. But I definitely have the opinion that hydroban is a much better product My opinion on liquid membranes from best to good: Ardex 8+9 Hydroban Aqua defense That being said, I’d choose a foam board like go board or hydro blok over any other system. Overall the easiest fastest method 👍

[@BonBon770]

The equivalent for hydrovan or aqua defense is ardex S1K. Not 8 +9, But 8 + 9 is good.

[@BathroomRemodelingTeacher]

@@BonBon770 I’d argue 8+9 being better

[@BonBon770]

@BathroomRemodelingTeacher I agree, but it's 2 different materials. S1K is equivalent to aqua defense. Or hydro ban.... Which are straight liquid water proofing, just like red guard. 8 + 9 is a mixture of 2 things. More like an epoxy.

[@discalt6489]

I was under the impression GoBoard was waterproof all the way through also.

[@BathroomRemodelingTeacher]

Yes it is 👍 I recently learned that, didn’t realize the foam has the same qualities as Wedi

[@taylo2tl]

Steve. Thoughts on Laticrete Hyrdoban system?

[@jamescolton1085]

Have you considered or used 100% silicone roof paint as a liquid membrane substrate? Why would you select or avoid it?

[@kyleaguiar3413]

I can't imagine it would spread very easily or uniformly, and aside from that I don't think thinset would adhere to it properly

[@kurtismoeller1512]

I stopped adjust my methods because the client can’t afford them. There’s to many jobs out there and they can use someone else. I use to aquadefense everything until I used Wedi. Then I realized I was breathing that shit in all day. As far as the membranes go. I only use Wedi subliner dry with 620 because there’s an actual waterproof sealant used not just thinset that will definitely wick.

[@kurtpearson2793]

My friend, please upgrade your screws on the go board. They make coated “GoBoard” screws that have a big flat top that is less inclined to countersink. They are great to use and covers their requirements for install.

[@BathroomRemodelingTeacher]

Yeah this was an older go board installation. And the are not required btw 👍

[@kurtpearson2793]

[@johnle231]

What’s that white stuff over cement board at 4:15?

[@rairequena8981]

Swimming pool paint.

[@sevendust07660]

Hi Steve, would you say Aqua Defense if better than Red Guard or are they pretty much the same?

[@BathroomRemodelingTeacher]

It’s not a whole lot better, but I would choose over Redgard 👍
