Pic 1. Sanded plywood receiving a coat of epoxy.

Pic 2. After the first coat of epoxy cured, it was sanded and this is the 10 oz fiberglass cloth being applied with a squeegee and rolled with a lamination roller.

The glass cloth is used not for reinforcement but to maintain an even epoxy film thickness. Without the cloth, it would be difficult to maintain an even thickness of epoxy during coating and sanding.

The other reason for the glass cloth is to make the top surface puncture resistant from dropped sharp tools.

The cloth is layed dried and the epoxy squeegeed on and rolled with a laminate roller to press the cloth down. Excess epoxy is squeegeed off to prevent the cloth from floating on the resin. The goal is to end up with a lamination that is not resin rich.
