Fiberglass Surface Preparation

Fiberglass substrates require thorough cleaning and sanding to remove mold release agents, wax contamination, and oxidation. Proper sanding profiles ensure strong adhesion for epoxy primers like Awlgrip 545.

Gelcoat Surface Preparation

Gelcoat surfaces must be degreased and sanded to remove gloss and provide mechanical adhesion. Proper preparation prevents fisheyes, adhesion loss, and coating failures in Awlgrip topcoat systems.

Previously Painted Surfaces

Existing paint systems must be inspected for compatibility, adhesion, and stability before recoating. Loose coatings should be removed and sound surfaces sanded to the proper profile before primer application.
