Today most professional tile setters back their tile with cement board instead because it offers almost the same durability with a lot less work.
Wehen installing vinyl tiling do you use cement board.
The cement board is not smooth.
However some people prefer to add another thin layer of subflooring between the concrete and vinyl.
Hi i expected to install tile on my bathroom floor so i installed cement fiber board.
Trim the last panel.
And the best part.
Tongue and groove material screw the underlayment down right through the vinyl with 1 1 4 in.
Thick cement board instead of the usual 1 2 in.
Installing over wood.
If you don t want to use cementboard install another layer of plywood before using an uncoupling membrane.
You can however use an uncoupling membrane over a single layer of sheet vinyl or vinyl tile.
Do not use an uncoupling membrane if the floor squeaks or has any give when you walk on it.
Chipboard cushioned vinyl flooring particle boards of any type oriented strand board osb interior grade plywood tongue and groove planking and hardwood floors are unsuitable substrates for direct installation of ceramic tile.
To smooth the floor i covered screw.
So technically if you are installing vinyl plank flooring onto concrete you already have a subfloor.
Apply the mortar bed.
This guide will teach you how to properly lay cement backerboard and use mortar to secure and level your subfloor before installing tile.
If you lay vinyl over it the vinyl will conform to all the imperfections in the cement board and your vinyl flooring will appear dimpled not smooth.
I know it seems like a smooth surface and it seems like it may fix some of the issues with the concrete floor but don t do it.
Installing cement board over a concrete subfloor.
If you have a concrete subfloor then you should not be contemplating installing cement board over it.
Unlike wood or drywall sub surfaces cement backerboard will not rot warp or grow mold and mildew when exposed to water.
Never install new tiles over existing tiles or onto an unprotected wood or plywood floor.
Here is my concern.
Cement boards that some in sheets.
As long as the subfloor is 3 4 in.
Place the first cement board sheet.
Fasten the first sheet.
It can be constructed from wood plywood plastic or concrete.
I have since decided to install vinyl sheet flooring.
Do it yourselfers can use it too.
