You can install your laminate, LVP, LVT (Luxury Vinyl Tile) over your existing floor. The existing flooring material needs to be adhered to your sub-floor by nail, staple, or glue. This can be hardwood, sheet vinyl, or tile. Additional preparation may be necessary to ensure the surface is smooth and leveled.
If you plan on installing the flooring material yourself, we recommend carefully following the manufacturing installation guidelines to ensure you don't void the manufacturer's warranty.
