How to Install Tile Backer Board

You should add to the title - ...to wooden sub floor.

You’re forgetting the step of applying thin set or glue to the back of the board
This will ensure that the tilies have the proper substrate for a lasting finish

Can I install two layers of 1/4” hardie backer boards one over another with use of mortar between?

Do have a video on working on concrete foundation

I found your video very educational. I had my kitchen floor tiled with 12x24 tiles about seven months ago and I remember the installer setting backer boards but not sure if he laid a thin layer of thinset before nailing the boards. Now as we walk over the floor we hear popping sounds all over. what could be the problem?

I bought 20 sheets of 1/2" thick sheets, recently had 2 pros give me estimates, both commented that I could have gotten 1/4" thick sheets, is this correct and what advantage is there using 1/2" thick?

On the toilet flange, would i need to raise the flange and tile under it, ot just butting the tile to the flange would be ok? Thanks.

Why Hardie board on floor and Durarock on walls?

Nice Video. Our House is coastal and is up on Pilings. The subfloor is Plywood, and the House flexes a lot.
I'm pulling out Carpet and laying down floating Vinyl Plank. The Kitchen Tile is staying (because it's still perfect after 15 years), and is set on top of 1/2" backer. I need to bring the elevation of the Subfloor up to match the Tile, so I'm planning to use 1/2" backer board for this.

My question is, if I'm just putting floating Vinyl Plank over this, do I need to Mortor the Backer Board, or is just Screwing it down enough?

Maybe I missed this but what backer is that? I have not laying tile in 15 years but I had used Hardy cement board back then yours looks more flexible and not as rough?

And do you have any experience using the new Curti board for any of that kind of stuff versus cement boards? Do you have a preference

Old boy tough not wearing knee pads

good

You mention nothing on the screw spacing, the spacing between the backer sheets or how close to the edge you should place a nail/screw...not very thorough!!!

When taping the joints,is it bad if the thin set is three times wider than what you put?

Thank you for the tips. How much space do I need between walls and boards? and between boards?

Thank you for your great videos! To the point and easy to follow for beginners like me!

Great video! Thank you for keeping it low key & easy

How much space should you leave between the wall and the edge of the hardy board

Thank you for this video, I am just learning it. May I ask you what type of mortar did you use to attach the backer boards to the plywood floor?

Looks like you guy don’t know about what side of the hardiebacker board is used for ceramic tiles and what is for painting the wall.
The trouble will happening after 7

AYE devil, where are you located lol I would love to hire ya

I did it myself thanks to Woodprix.

How long do you have to wait to put the tile down after you lay the BB?

I like to get a sponge and some water to smooth out the thinset when taping the joints. Makes it look nice and blended together.

great vid thx

What is the purpose of putting mortar under the backerboard?

Hi Sgt, When you use the “mortar” to stick down the Backer board, is the mortar the same as used for bricks or is it cement based tile glue or rubber based glue ? Not sure if there’s a subtle translation difference. Nice Video too. Cheers

Question: If I have Vinyl Tile on my floor now, which is as solid as cement- can I install hardibacker board on top of that so I can install porcelain Tile? I tried removing the vinyl tile but its extremely difficult, even with heater guns/torch. I have 400 sq ft to do and don't think its logical to kill myself on the removal of vinyl tile. Never came across this before after 30 years of tiling.

donot you need another layer of plywood before you screw the backerboard

Can’t you put a rag down in the register before you lay it ?

next guy who has to remove that is going to be pissed

There are special circular saw blades for cutting backer board. They have like only 4 to 6 teeth, and keep the dust down. Great video. I"m going to use this method for my small bathroom tile job. Is it highly recommended to put mud below the backer board?

👍

How do I install the backer board onto wooden floorboards?

Whenever handling or cutting / hammering these sheets, i would strongly recommend a silica-standard mask i.e. not just when you are grinding it. As the chap states, Silica is nasty stuff and you definitely don’t want it in your lungs. Even cleaning up afterwards, keep the mask on.
You can’t get hold of such masks at the moment, due to people buying them for CV or to sell-on at x10 normal price.

Simple, step by step, straight to the point. Great video, Thank You

Just ripped out bathroom floor. It has no floorboards and previous owner used a thick chipboard and tiled over them. What shd i do from here. i was thinking to lay plywood and then cement boards and tile over it. Or is it just as good to layne the plywold and brush on Aqua defense water proofing solution. Also i understand u leave gap at edge of wall for expansion of cement boards but doesnt that leave a weak point

Knowing that my bathroom floor needs leveling, I was wondering if I can use a gypsum based SLU to eliminate the need for "backer board", as it can be applied up to 1 1/4" thick and the nominal thickness would be 1". What do you think ?

Will the coated nails react to the mortar mix?

You OG with that hammer!

This board is so heavy, with screws, why do you need mortar? If, God forbid you have to remove the flooring years later, won't the mortar be a major clean up problem?

Can I use these over floorboards

I've got a floor with 2 layers of vinyl tile, one is 10% Chrysotile asbestos, so instead of ripping them up I'm going over it with 1/4" HB.

What if the floor wasn't perfectly level and your planning on using 12 x 24 inch tiles? Is the mortar under the hardy backer sufficient to fill those gaps and level the floor? Or do you need to use floor leveler? And if so, do you use floor leveler on the subfloor or on top of the hardy backer? I'd assume you'd use floor leveler on the subfloor if required.

is that 1/4 in backer board youre using ?

Sgt. Donovan, My floor decking is 1/2" plywood and there are definitely some spongy spots in areas of medium to high traffic. Should I use 3/8ths backer board or will the regular 1/4" be sufficient? Thank you for this video and especially for your service.

Thank you! Good video. Simple and informative.

So what do you do at the floor and wall joint ?

Great video, thanks for this! I’m tackling this project in my bathroom this weekend. So far I ripped everything out and dry fit the backer board. I have a question though. I’ve watched a lot of video and it seems some guys use thin set and screws and some guys just use screws. Is there a big difference? Thanks

Thanks for the video. I pulled up three layers of flooring being vinyl sheet, vinyl sheet, and the top layer Pergo boards. The bottom layer was a large glued down vinyl sheet. Most of the glue layer didn't come up. It's very thin to the point it can't be measured. Does that need to be removed or can I thin set over it and screw? Also, wont applying thin set directly to the subfloor or that glue layer ruin the subfloor? What do you think about putting down tar paper/roofing paper over the old vinyl glue layer, putting thin set on the tar paper, then screwing it down?
