So technically if you are installing vinyl plank flooring onto concrete you already have a subfloor.
Wehen installing vinyl tiling do you use cement board.
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.
And the best part.
If you don t want to use cementboard install another layer of plywood before using an uncoupling membrane.
If you have a concrete subfloor then you should not be contemplating installing cement board over it.
Drywall screws spaced every 6 in.
Place the first cement board sheet.
To install ceramic tile over wood the wood surface must be structurally sound enough to support the weight of the tile.
It can be constructed from wood plywood plastic or concrete.
The cement board is not smooth.
However some people prefer to add another thin layer of subflooring between the concrete and vinyl.
I have since decided to install vinyl sheet flooring.
Fasten the first sheet.
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.
Do not use an uncoupling membrane if the floor squeaks or has any give when you walk on it.
Trim the last panel.
Unlike wood or drywall sub surfaces cement backerboard will not rot warp or grow mold and mildew when exposed to water.
As long as the subfloor is 3 4 in.
This guide will teach you how to properly lay cement backerboard and use mortar to secure and level your subfloor before installing tile.
Never install new tiles over existing tiles or onto an unprotected wood or plywood floor.
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.
Thick cement board instead of the usual 1 2 in.
To smooth the floor i covered screw.
You can however use an uncoupling membrane over a single layer of sheet vinyl or vinyl tile.
Installing cement board over a concrete subfloor.
Installing over wood.
Do it yourselfers can use it too.
Cement boards that some in sheets.
Apply the mortar bed.
Mix a batch thinset mortar following the manufacturer s directions using a bucket and margin trowel or putty knife.
Here is my concern.
