If glued osb is going to expand swell with the first coat of ardex so then you need another coat.
Can i put down fake tile floor over osb.
Ceramic tile is a very popular upgrade for kitchens bathrooms patios and foyers.
Still should sand flatten the joints first.
The osb i always see has raised joints from being glued to the joist.
Direct gluing vinyl sheet and tile to osb subfloorsinstalling a glue down vinyl floor sheet or tile directly over oriented strand board osb subflooring has become a hot topic for me of lately.
First of all ivc says the osb must be an underlayment panel and must be underlayment grade as specified and warranted by the manufacture not subfloor grade which is used in new home construction.
While this is not a definitive guide to hardwood installation over osb panels there are some important points to ponder.
We ve installed a number of ceramic and stone floors.
Ivc says you can direct glue down to oriented strand board osb all others say no.
I have had people asking about installing sheet lvt and vct directly to the osb subfloor without the use of an underlayment most flooring vinyl flooring manufacturers do not allow direct glue down.
The job isn t difficult when it s done right.
Hardwood can make for a durable and beautiful floor but small mistakes in the subflooring or installation can wreak havoc and buckling squeaky uneven floors can all result from poor installation.
There is an advantage to sheeting with 1 4 plywood over the osb but it wouldn t be the complete solution.
It is resistant to water and scratches making it more durable than hardwoods or vinyl tile for these areas.
So i researched this.
The ridges on the osb seams should be ground down with a belt sander to minimize the variation between boards.
I just sand them down and go for floating floor.
The cement board must have a layer of thinset under it use a 1 4 square notch.
How light can i go with the thickness so.
You would still need to build up the low spots and take down the high spots.
The underside of an osb subfloor must be properly protected from.
Going to put down cement board.
But done wrong it can leave a homeowner with a feeling of defeat.
Manufacturers generally recommend that the deflection of the subfloor system be limited to no more than span 360 under total load.
Osb must be protected from water or moisture exposure during shipping and throughout the installation process.
You can use 1 8 door skins cheap and plentiful here but ymmv or a similar product to build up the low areas then sheet over with 1 4 plywood.
Tile can be safely installed to the redgard coated osb with one of custom s polymer modified thin set or medium bed mortars.
