When laying EVP flooring, do you need to use backer board. I am installing over a hard wood floor and have LVP Underlayment
Go to the manufacturers website. They have installation instructions and video. This will get you started.
EVP are thicker than luxury vinyl planks and click together while LVP are glued down. They have a built cushioning layer so they do not need an underlayment. They are a cheaper and great alternative to laminate. And they are waterproof.
Engineered luxury vinyl (EVP) can go on top of concrete, plywood and tile. It can even go on top of radiant heat.
