Using Patching Compound with Plywood Underlayment

Using Patching Compound with Plywood Underlayment

Quarter-inch lauan plywood is the top material for underlayment among home renovators and contractors. It's quality is unsurpassed, and it is extremly durable and long-lasting. Amoung Manufactuers of Vinyl Flooring, Hardwood Flooring, Tile Flooring, and Laminate Flooring, the choice is clear, and Luan is the top pick. Of course before you proceed with any home improvement product, you should check with your flooring manufacturer before you proceed with installation to confirm.
There are two types of Luan:

Luan Type 1 with an exterior glue, is the more resistant to delamination, and should be installed under very durable flooring

 Luan Type 2 with a water-resistant glue.

The type is normally indicated on the panal edge. Usually on the 4 foot edge, on the 4x8 sheet. There are three possible standards of Luan, which are

BB -  the highest grade and should be used whenever possible.

APA’s installation guidelines for 1/4-inch plywood should be followed when installing lauan plywood, but installers BEWARE: Lauan is made under a wall-panel specification of the International Hardwood Products Association (IHPA). No manufacturing specifications support its use or gauge its performance as an underlayment.
