Step 1:
Choose the appropriate volume for your project. The type of fiberglass used will determine the amount of resin needed.
Step 2:
Make sure to agitate or stir the product thoroughly before use.
Step 3:
Mix 1 to 2.% MEKP, in resin solution thoroughly. Please refer to the Catalyst Concentration Chart for Quantities.
Step 4:
Thinner fiberglass can easily be wet through. To thoroughly wet out heavier materials, apply resin first to one side, then flip the glass over to wet out the other side. Use paint-style rollers to distribute resin quickly.
Step 5:
Roll each layer with a glass roller to remove air. The fiberglass will go completely transparent when it is adequately wet.
Step 6:
Add Sanding Aid (Product #123833 must purchase separately) to the final coat to allow a full cure and a tack-free surface. Refer to the Sanding Aid Chart for quantities.
Cleaning General Purpose Polyester Resin: Use Acetone to clean brushes and rollers. A small bucket of solvent can be used to clean tools.
