Well today due to lack of knowledge, many home owners are cheated by dealers and retailers. They often hand over commercial ply as waterproof or marine ply at the cost of waterproof plywood.

The Test
1. Place a piece of given plywood in pressure cooker with sufficient water level (the plywood shall sink inside).
2. Let minimum of 5-6 whistles to blow. Turn of the stove knob.
3. On cooling, open the cooker pan and check.
A good quality waterproof plywood will have no effect or changes on performing this test. Whereas a low quality waterproof ply or commercial ply will show changes like deformation, a bend, veneers come apart, or similar on performing this test.
