Laminate flooring is popular for use in kitchens, bathrooms and in other parts of the house. Because laminate flooring is less expensive than true hardwood or tile and is easier to install, it has become the choice for do-it-yourself homeowners. Laminate must be sealed while it is being installed or shortly thereafter to prevent moisture from penetrating it through the subfloor. If left unsealed, the laminate could become discoloured or buckle.
Things you need
Open the end of a tube of silicone sealant with the poker attached to a caulking gun. Load the tube of silicone sealant into the gun. Depress the plunger and pull the trigger to get the silicone to the tip of the tube.
Dampen a clean cloth and begin to squeeze a bead of silicone between each laminate plank while laying the flooring or just after installation. Wipe away excess silicone sealant with the damp cloth.
Apply a border of silicone sealant around the perimeter of the laminate flooring, leave no edge or joint untreated. This will be a large prevention measure to keep moisture from penetrating through the tongue and grooves as well as the border edges. Let it dry as long as directed by the manufacturer.
Apply the first coat of water-based polyurethane to the laminate flooring with a polyurethane brush. Start in the corner furthest from the room's entrance and work toward the entryway. Let dry for three hours and then apply a second coat of water-based polyurethane. Brush on a third coat, if desired thereafter.
Allow the water-based polyurethane to set into the laminate floors to seal them for a period of 48 hours after the second coat or third coat has been applied.
