Step 1: Underlayment (Recommended) Do you have to use an underlayment with glue down vinyl planks or tiles? Technically LVT and LVP can be installed directly on previous vinyl, concrete and smooth plywood, but I DO NOT recommend it. The reason is because if you ever want to change the flooring, removing the adhesive is going to be a MAJOR pain. Floating vinyl plank floors are a great choice for bathrooms, kitchens, laundry rooms, and bedrooms. If you are laying floors in a large and expansive area, a glue down flooring application can provide more durability. Of course, glue-down applications are appropriate for smaller rooms as well.
