How-To make a fiberglass panel

Materials & Tools Needed: Epoxy resin and hardener Pre-cut fiberglass cloth (woven or mat) Mixing containers and stir sticks Paint rollers (foam or solvent-resistant) Aluminum bubble roller (a.k.a. consolidation roller) Clean flat mold surface (glass, melamine, or waxed form) Mold release agent (optional but recommended) Protective gloves, goggles, and a respirator Utility knife or scissors Plastic spreaders (optional) Sandpaper (for prep or finishing) 🪚 Step-by-Step Instructions: Step 1: Prepare Your Mold Surface Clean the surface thoroughly. Apply mold release agent if you want to easily remove the panel later. Make sure the mold is level and free of dust or imperfections. Step 2: Cut and Lay Out Fiberglass Pre-cut your fiberglass to the shape and size needed. Lay the fiberglass dry onto the mold to check the fit. If layering, set each layer aside in order for easy access. Step 3: Mix the Epoxy Resin Mix the epoxy and hardener according to the manufacturer’s ratio (e.g., 2:1). Stir thoroughly for at least 2–3 minutes, scraping the sides and bottom of the container. Step 4: Wet Out the Mold Surface Using a paint roller, apply a thin layer of epoxy to the mold surface. This will help the first fiberglass layer stick and reduce air entrapment. Step 5: Apply the First Layer of Fiberglass Carefully lay the first pre-cut fiberglass piece onto the wet epoxy. Use your gloved hands or a plastic spreader to gently pat it flat. Step 6: Wet Out the Fiberglass Use your paint roller to saturate the fiberglass with epoxy. Roll in multiple directions to ensure full saturation. Avoid overloading the fabric. Step 7: Remove Air Bubbles While the resin is still wet, use your aluminum roller in overlapping strokes to: Press down the fiberglass into the resin. Work out trapped air bubbles. Consolidate the layer and improve resin distribution. Step 8: Repeat for Additional Layers If doing multiple layers: Lay the next fiberglass sheet. Wet it out with resin using the paint roller. Use the aluminum roller again. Repeat until all layers are applied. Step 9: Let it Cure Leave the panel undisturbed in a dust-free area. Follow the resin manufacturer’s cure schedule (usually 8–24 hours). Step 10: Demold and Finish Gently pry the panel off the mold after it has cured. Trim edges with a utility knife or sander. Optionally sand and coat with UV-stable clear coat or paint if used outdoors. ✅ Pro Tips: Work in a well-ventilated area with proper PPE. Keep your tools and rollers clean—use acetone or a designated epoxy cleaner. Use a heat gun or hair dryer lightly if stubborn bubbles appear, but don’t overheat. Avoid air drafts and temperature swings during curing.
