Installing Laminate Flooring On Plywood Subfloor. After vacuuming or sweeping the subfloor to clean it add a plywood layer if the subfloor is in very bad shape but do not overlap the sheets. A breathable foam-type underlayment is generally used when installing laminate flooring over plywood or OSB subfloors.
The smooth finished side goes up when you install OSB as a subfloor. Sometimes it also comes with an attachable formula. Before installing a tile floor a subfloor and underlayment is necessary.
A plywood layer is not necessary if you are putting down wood laminate.
A subfloor is the layer at the very bottom of your shower pan. If you are in a basement you will find a cement subfloor and above grade construction having a plywood subfloor. This is to connect in the bottom of laminate flooring. Unlike laminate flooring most vinyl floors are designed to lay directly on top of the subfloor.
