The general method of using polyurethane foam cell openers is as follows:
Preparation: Make sure the work area is well ventilated and wear appropriate protective equipment.
Clean the surface: Before applying the cell opener, make sure the foam surface is clean, dry, and free of oil and dust.
Spray the cell opener: Spray the cell opener evenly on the polyurethane foam surface, paying attention to even coverage.
Wait for penetration: According to the product instructions, wait a few minutes, usually 5-10 minutes, for the cell opener to penetrate the foam.
Cell treatment: Use a knife or other tool to gently remove the foam, paying attention to controlling the force to avoid damaging the underlying material.
Clean up and post-processing: Clean the work area and trim the treated surface if necessary.
