How to Waterproof Laminate Flooring

Updated February 21, 2017

Waterproofing your laminate floors may assist in keeping the flooring looking like new. Laminate floors are often installed in kitchens and bathrooms; both spots are vulnerable to water damage. When a flood occurs, the laminate may be ruined. Avoid this issue by properly waterproofing the floor prior to a water disaster. Before beginning this project, make sure the flooring is dry underneath and around the edges. Use towels or fans to dry the area if needed.

Clean the laminate floor according to the manufacturer's recommendations. Make sure that all dirt, dust and debris are cleared from around the edges and in the corners.

Pull the edges of the laminate floor up around the walls. Apply a line of epoxy glue to the outer edge and press down, sealing the outside. Allow the epoxy glue to dry for at least 12 hours.

Apply floor sealant, using a paint roller. Go in one direction with the roller for a smooth finish. Cover the entire floor, including the edges. Allow the sealant to dry for 24 hours.

Apply a second, and then a third layer of the sealant to the floor. Allow 24 hours between coats.


Floor sealant is available from most home improvement outlets. Consult a professional for the best sealer for your particular laminate flooring.


Epoxy glue emits fumes. Make sure the area is well-ventilated.
