Plywood underlayment is a thin plywood material that is most commonly used under resilient flooring materials such as vinyl and linoleum sheets and tiles.
Installing carpet on plywood.
Carpet tiles can adhere to concrete plywood or particleboard subfloors.
Use two sided tape for lower grade carpet and indoor outdoor adhesive for higher grade.
Both items can be attached with nails.
Before you can install carpet tiles you must prepare the existing floor.
Apply the carpet adhesive to the plywood in an even layer with a sprayer brush or trowel.
It can also be used under hardwood laminate and carpet but this is much less common these days because subflooring is typically smooth enough for these materials many of which are installed with a different type of underlayment or pad.
Coat the back of the carpet with adhesive if so directed by the adhesive manufacturer.
In some cases you can also install carpet tiles over existing wood tile or vinyl flooring so long as the existing flooring is no more than an inch thick.
Add baseboard or trim to the walls.
Install a metal strip or transition molding over the carpet edge in any doorways to protect the carpet.
For the best results install carpet when the temperature is between 55 f and 95 f and the humidity is between 10 and 65.
