Excellent tips! Thank you!

[@bobscaping]

Keep up the great work BRT! 🎬👏👏👏👏👏👏👏

[@LucasXL1995]

Love your content. excellent teacher and your content is enjoyable to watch.

[@boomdizzle87]

Would Hydroban be enough if you are waterproofing the transition from bathroom floor to a curbless shower using a schluter shower pan? Trying to prevent having a bump since i am doing the exact tiles as this video

[@SKOKMKJK]

I am not sure how high I can do at tub bottom for the waterproofing. Should I make same height with tile top elevation? Thank you!

[@timothytomei4303]

Thank you for this.

[@GeneralSeptem]

Is there any risk or benefit to waterproofing before the tub goes in (i.e., under the tub)?

[@rollogic2988]

Do you always roll two coats of Hydroban? And do you think RedGard or the Mapei Aqua Defense is just as good?

[@REGDORTNARG]

good info. thanks

[@TheIrishboy99]

How long is it recommended for floor leveller to dry before waterproofing?

[@meldlew]

We have a vent on the floor next to the toilet, any suggestions on how to keep water out of it? We’ve had issues with water from the toilet or splashing from the tub, going down the vent and running down the wall on the floor below

[@OldHeapOfProblems]

If you use the feather finish in the joints, such as between the tub and floor, doesn't that create a problem for expansion? It's essentially removing the expansion space, no?

[@user-ks4er2ew3e]

Can I waterproof the same way before sheetrock goes up? Put the board over the mesh

[@odugudes]

Thanks for this! Would you recommend this for creating a wet room for a 110sqft bathroom on a second floor? I was hoping to avoid anything that requires mechanical joints that might be vulnerable or that might cost more.

[@meldlew]

We build a wet room for our handicap son and they attached boards at an angle to the floor joists to raise the floor up on one side to drain…

[@mitcheroni8117]

Hey man!! Ive got a bunch of ditra because i was intending on laying tile in the bathroom. However i am now using the waterproof Laminate tile . What do you think about using the ditra under the LVT? should i line the floor in kerdi roll? red guard? what would you do? Thanks man LOVE your videos!

[@mitcheroni8117]

i have plywood by the way

[@dannyv5175]

What kind of mesh is that?? Is it possible to use a kerdi band interchangeably? Thanks, your videos are awesome

[@BathroomRemodelingTeacher]

It’s a mesh for liquid membranes. And kerdi band can not be installed this way with it 👍 amzn.to/3XkgCUN

[@SKOKMKJK]

What do you think about using Red guard instead of Hydro ban? I have a lot of red guard left over from tub area.

[@BathroomRemodelingTeacher]

That works too 👍 I don’t use much red guard now that I use hydroban. Hydroban is a lot thicker and drys faster

[@SKOKMKJK]

@@BathroomRemodelingTeacher Thank you so much for the reply. I am learning from you every day - in fact, I see your face more times than checking on wife lately!

[@PhillyPianst]

Great video! Are you going to use an inside flange on the toilet? If so, do you find them cause clogging issues due to narrowing the opening? I have 3 " and am trying to decide whether to go inside or outside type flange

[@BathroomRemodelingTeacher]

I’ve never seen it happen. But I’ve always used American standard toilets which I think work better. The outlet of toilet trap is less than 3”, so in my mind it’s not restricting anything 👍

[@PhillyPianst]

@@BathroomRemodelingTeacher awesome. I'll go with the inside flange which allows me to waterproof to the outside of the pipe since I don't have to slide the hub on the outside of the pipe. Thanks!

[@seanlavery6477]

My problem too. I'm going to go with the outside flange and scratching my head on how to waterproof it

[@danemiller4724]

What if you're not tiling the walls? How would you deal with the mesh at the sides?

[@BathroomRemodelingTeacher]

Hold the waterproofing below wood trim 👍

[@philroz3080]

I’m using Ditra before installing the porcelain plank tile, but I’m really concerned about the area in front of the tub/shower. Would you waterproof the OSB floor with this before installing the Ditra ? I just want to be certain that everything is extremely waterproof !!!

[@BathroomRemodelingTeacher]

This section of my ditra install video should help 👍 kzbin.info/www/bejne/sH_VeKeumc6IgLc

[@philroz3080]

Thank you

[@Alphasig336]

If your removing tub/shower I’d extend Ditra under and beyond tub. If it’s a drop-in tub you can run Kerdi up corner

[@IRSavage303]

What if im putting lvp in the bathroom? Can i use the same system or i dont need to use that system

[@BathroomRemodelingTeacher]

Yes 👍 liquid waterproofing before the lvp is a good idea 👍

[@Jubileejones]

Would I need to use a waterproofing if my subfloor is concrete with self-leveler over it? My bathroom is in the basement.

[@davidtalavera2462]

I would. Concrete and cement is still porous which means water will eventually seep down… it’s just for peace of mind lol

[@growermo940]

Did yo remove the spray foam around the wall and tube or did you just put the water membrane over it

[@BathroomRemodelingTeacher]

Yes, I just cut and removed what I could and waterproofed over. The area near tub I filled with feather finish an hour or so before apply the liquid membrane

[@growermo940]

@@BathroomRemodelingTeacher well I could see that spry foam being a problem when doing the trim

[@BathroomRemodelingTeacher]

Stay tuned for next video then 👍

[@danemiller4724]

For the sealant at the tub, do you put this down before or after tiling? Or both?

[@jamesfinney8841]

Would you water proof like this if you're going cheap and putting laminate or vynil flooring in a first floor bathroom?

[@nmatthew7469]

Purple board works 👍, only sold at Lowe's, not the depot.

[@JustinMentionedIt]

Same as green or blue all does the same

[@nmatthew7469]

@@JustinMentionedIt actually, you're correct, since 2006 there is no difference.

[@nicolesherrod2579]

How would you waterproof an upstairs floor, without concrete underneath? I’m trying to waterproof our upstairs bathroom and my boyfriend keeps saying you can’t. Can you use this method on plywood? Kids keep getting water out of tub and sink. Went through ceiling.

[@BathroomRemodelingTeacher]

Yes 👍

[@nicolesherrod2579]

​@@BathroomRemodelingTeacher Awesome, going to give this a try! Let you know how it goes, appreciate the step by step videos. I’m new to remodeling diy projects, especially as a woman trying to go room by room and remodel the entire house by myself. Can’t afford to hire contractors.

[@vannguyen3251]

Thám 😊

[@ADUSEI6111]

So could you technically use Hydrro Ban as an uncoupling membrane for concrete?

[@BathroomRemodelingTeacher]

Uncoupling is a whole other theory (created by Schluter, supposedly) This is just a traditional crack isolation membrane that provides waterproofing

[@ADUSEI6111]

@@BathroomRemodelingTeacher Oh That's great then..I have a 5 gallon bucket of Hydroban.... I'm glad i can use it for more than jus the shower walls... Thank you for the reply.

[@Alphasig336]

Why not Install ditra heat or Ditra on bathroom and then float over Ditra after cable is installed. You only need 1/8 - 1/4. Same end result.

[@BathroomRemodelingTeacher]

4-5 times the cost

[@josekacv0420]

Paused the video and zoomed in, that floor was not level... did you mean what mater most is to be flat with no high spots??

[@FlylightD]

Hahaha!!! GTFOOH!

[@TheDuckSquash]

I don't think 15-22mm per coat is correct, you would be hard pressed getting that with 4 coats let alone per coat

[@BathroomRemodelingTeacher]

Each wet coat should be 0.015 - 0.022 inches (0.4 - 0.6 mm) thick. The combined dried coating should be 0.020 - 0.030 inches (0.5 - 0.8 mm) thick.

[@TheDuckSquash]

Found the technical data sheet for HydroBan in Australia and says very similar thing 0.6 - 0.9 @@BathroomRemodelingTeacher

[@madirishchef]

The best tip for waterproofing your bathroom is to get a professional to do it.

[@roddeloach1]

If you have a plywood subfloor, can you use hydroband or regrad before leveling?
