Do I Glue the Edge on a T&G Engineered Floor?

Tongue and Groove Flooring

• Each plank of a tongue and groove floor has a groove on one of the long sides and on one of the short sides of the plank. On the two remaining sides are tongues that fit securely into the grooves. The floors are called "floating" because the planks are secured only to each other and "float" over the subfloor. In addition to easy installation, floating floors are said to be quieter and warmer than floors that are nailed or glued down.

Subfloor and Underlayment

• Floating floors can be installed over any hard, level surface, including tile, concrete or vinyl. Lay a thin sheet of high-density foam under the floors to provide a cushion and to help dampen sound. To prevent moisture damage to floors laid over a concrete slab, lay 6 mil plastic between the concrete and the foam.

Adhesive

• While you don't glue the edge of the plank to the subfloor, gluing the tongue in the groove can help extend the life of your floor. Use a thin layer of adhesive and wipe off the excess as soon as you fit the planks together. Check with your floor's manufacturer for suggestions regarding adhesives to ensure your project is successful.

About Engineered Wood Floors

• Engineered wood floors are made of thin strips of wood glued together to provide a strong, durable plank that is less prone to warping, bending or cracking than solid wood. The top layer of each plank is a wood veneer treated with a durable finish. Unlike solid wood flooring, engineered wood can be installed in basements. According to This Old House, engineered wood is available in a variety of wood types and will outlast most solid wood flooring.
