How to Patch Dents in Fiberglass Decking

Fiberglass decking is one of the best choices you can make for your home. It is constructed from fiberglass, a highly versatile material for various indoor and outdoor applications. Fiberglass consists of extremely fine glass fibers, combined with resins, to produce one of the most durable construction materials. Pools, roofing, decking, doors, flooring, insulation, automobiles and boats are just a few of the items that utilize fiberglass for product manufacture. A fiberglass deck is one of the modern trends in outdoor home installations. Although fiberglass doesn’t rot or warp like  traditional decking materials, it may develop dents with time. Should dents occur on your decking, it helps if you know how to repair them.

Step 1 – Clean the Surface

Wipe the area to be repaired with a damp cloth. You want to be sure that you apply repair materials on a clean surface. Dirt and debris tend to hamper an effective bond.

Step 2 – Prepare Filler and Hardener

You can get a fiberglass epoxy kit from a home improvement center or hardware store. Be sure to ask for a kit that is suitable for fiberglass decking. Various fiberglass kits are available on the market. Some may be used for general fiberglass repairs while others are produced for specific items. The epoxy kit contains a filler and hardener. Prepare the filler and hardener for application in a small container. Be sure to mix well until you obtain a uniform color.

Step 3 – Test Application

Just to be certain you have the right fiberglass kit, it is best to apply the filler to a small section of the dent first. This will enable you to see how it works and confirm if it is compatible with your decking. Allow the filler to work for the specified duration. If you notice any adverse effects, it is best to go back to the store and obtain a more suitable fiberglass kit.

Step 4 – Fill the Dent

Spread the filler carefully over the dent with your plastic putty knife. Apply in small portions and press in firmly so that it compacts well within the dent. Spread the filler in one direction only, so that bubbles do not develop on the surface once it dries. Apply enough filler so that the dent can fill up to the same level as the rest of the decking. Allow about 10 minutes for the filler to cure.

Step 5 – Sanding

Use a piece of sandpaper to sand the repaired area to the desired finish. This will help smooth out the area and make it level with the surrounding decking.

Step 6 – Apply Gel Coat

Be sure to obtain a gel coat that matches the rest of your decking. Mix in some non-slip additive. Use a nap roller to coat the repair area with gel coat. Stir the mixture continuously as you apply, so that the additive doesn’t settle. Allow the gel coat to dry completely before you walk on the deck.
