How to Seal Laminate Flooring

Author: Staff Writer
 Laminate flooring is a very popular choice in homes because of its variety of choices and installation that even those not experienced with home repair and maintenance can complete. It is important that it is sealed, however, to keep water from leaking into the area between the flooring and the subfloor, which will damage the floor and cause mold and mildew to grow. 

Seal the Joints Around the Plumbing

Identify the joints near the plumbing and apply sealant to them. Make sure the sealant you are using is formulated to prevent mold and mildew. Your laminate flooring manufacturer may specify a brand of sealant to use. If so, be sure to use that brand.

Seal Around the Appliances

Use sealant to prevent water seepage from appliances in the room. Run a thin layer of sealant along the edges where the appliances meet the floor. If you are sealing laminate flooring in a kitchen, be sure to seal under and along the edge of the refrigerator and dishwasher, and under the sink.

Seal the Room Border

In laundry rooms and bathrooms, it is important to seal the border of the entire room due to the moisture that these rooms can be subject to. Make sure to fill all of the expansion joints in the doorways as well.

Install Transition Strips

You may need to add T-molding transition strips in the doorways bathrooms and laundry rooms as well to complete the sealing process. These strips function to provide transition in a house between different kinds of flooring. To install these transition strips, use nails or screws to install the track in the doorway. Make sure the strip does not buckle. If necessary, the transition strip can be adjusted to fit the space by making cuts in the strip. If the strip feels rough, it should be sanded down. Use a hammer to lightly secure the transition strip.

Expert Opinion 

Quote:  "To install flooring around pipes, drill a hole in the plank that is ¼ to ½ inch larger than pipe diameter. Cut the plank across the center of the circle, position on the floor, glue plank pieces back together and clamp (do not glue laminate to subfloor). Cover expansion gaps with molding or pipe rings when the floor is complete. Water pipes require silicone sealant."
