Regarding this, what is best to put under vinyl flooring?
No Thick Underlayment Under Vinyl Flooring However, if you are installing vinyl flooring over a concrete sub-floor, you will need a very thin vapor barrior, such as Visqueen Vapor Barrier underlayment to protect your flooring from moisture.
One may also ask, how do you install vinyl flooring on an uneven floor? There is no need to use an underlay with our vinyl flooring. If your sub floor is uneven we recommend you use a good-quality latex self-levelling compound, alternatively smaller uneven spots of more than 3mm can be filled with a rapid-drying deep-fill compound.
Then, what is the best underlayment for sheet vinyl flooring?
Vinyl Underlayment The preferred underlayment for vinyl flooring is 1/4″ plywood. Some installers will lay vinyl over existing OSB or plywood subflooring if it is in excellent condition.
How do you prepare a concrete floor for vinyl flooring?
Clean and smooth the concrete. The slab doesn't have to be level for vinyl, but it must be smooth and relatively flat. Fill large cracks and dips with a floor-leveling compound designed for concrete. Sweep and vacuum the entire floor thoroughly before rolling out the vinyl.
