Polyester resin is the most widely used and the cheapest type of resin. Resin is a thick fiberglass liquid that when mixed with 2 percent catalyst turns solid. You can use more or less catalyst to change the amount of time it takes to set, but don’t use much less than 2 percent. Polyester resin adheres to almost any surface, including metal, wood, foam, plastic, and ceramic. When used on porous materials such as wood, the resin will not penetrate the wood and will form a strong bond unless diluted. Polyester resin is also used for the gel coat, which is fiberglass paint that must be thinned for spray application. Polyester resin can be thinned using no more than 10 percent acetone. A little more and the fiberglass won’t fully harden.

Step 1: how to dilute resin

Put on a respirator and a pair of rubber gloves. Fill a small bucket 3/4 full with polyester resin using a measuring cup. Keep track of the amount of resin you poured into the bucket.

Step 2: dilute polyester resin

Add 10 percent acetone to the resin or 10 parts resin to 1 part acetone. Stir the acetone into the resin well until completely mixed.

Step 3: how the resin is prepared

Add 2 percent catalyst to the bucket of diluted resin and stir well with a stir stick. The fiberglass will harden within 30 minutes of adding the catalyst. Apply the resin to the surface of wood or other porous material with a felt roller. Spread the resin as evenly as possible in a thick layer and allow the resin to harden.
