The flooring associate at the home depot canada suggested using vapour barrier with tuck tape to seal the concrete.
What can i put under vinyl flooring on concrete.
The first move in installing vinyl plank flooring over concrete is to determine the area that needs to be covered.
However you ll want to use one in every other application including covering existing hardwood floors vinyl flooring that isn t cushioned and concrete floors.
Done we had both on hand.
The most asked question is on whether you need underlay for vinyl plank flooring or not.
If you are installing your vinyl plank flooring over a concrete subfloor you may want to use an underlayment for three reasons.
The underlay adds an extra cushion on your floor and makes it softer and increase the floors insulating capability thus keeps it warm even during winter.
The hardest part of the job is often cleaning and leveling the concrete base.
For the case of concrete floors an underlay is necessary for your sub floor.
Repair any holes or cracks.
If you re laying the lvp over an existing cushion backed vinyl floor or a below grade tile floor then you won t need to use an underlayment.
You can lower high spots with a grinder.
Any minor bumps can be removed with a masonry chisel and small sledgehammer.
First it will give you some added cushion to help make the floor softer to walk on.
Vinyl flooring is very durable and fits over most surfaces including concrete.
Fortunately concrete floors can be covered with a variety of more attractive materials including vinyl tile which is simple to install.
Moisture will get through so even if you don t add an additional underlay you do need to seal the concrete.
Although the flooring comes in a variety of forms planks are installable with a minimal amount of tools and measuring.
However some people prefer to add another thin layer of subflooring between the concrete and vinyl.
This additional layer can improve insulation and should make your vinyl plank flooring warmer and less resonant.
Second you may want an extra vapor barrier above the subfloor to reduce any risk of moisture.
So technically if you are installing vinyl plank flooring onto concrete you already have a subfloor.
