Fiberglassing a deck is a great way to protect it from water damage and wear. Here’s a straightforward guide on how to do it:

Prepare the Deck:
- Clean: Ensure the deck is completely clean, dry, and free of any debris or loose materials. Use a broom or a blower for this task.
- Repairs: Fix any cracks or damages in the deck with wood filler or similar products and sand smooth once it’s dry.
- Sanding: Sand the entire surface to create a slightly rough texture. This helps the resin to adhere better.
Apply the Fiberglass Mat:
- Cutting the Mat: Measure and cut the fiberglass mat to fit your deck. It’s better to have the mat in large pieces to reduce the number of seams.
- Positioning: Lay the mat on the deck, ensuring it extends to all edges. If your deck has edges or unique shapes, press the mat down into contours and corners.
Mix and Apply Resin:
- Mixing Resin: Follow the manufacturer’s instructions to mix the fiberglass resin. It typically involves adding a catalyst or hardener to the resin.
- Applying Resin: Use a roller or brush to apply the resin over the fiberglass mat. Work quickly and ensure the mat is thoroughly saturated. Avoid leaving any air bubbles or dry spots.
- Adding Layers: Depending on the product and the desired strength, you might need to add additional layers of mat and resin. Always allow each layer to cure as directed before applying the next.
Cure and Finish:
- Curing: Allow the resin to cure as per the instructions. This can take several hours or overnight, depending on weather conditions and the type of resin used.
- Sanding: Once cured, sand any rough areas to create a smooth finish. Be careful not to tear the fiberglass.
- Topcoat: Apply a sealant or topcoat if desired. This can enhance the appearance of the fiberglass and provide additional UV protection.
Maintenance:
- Regularly check the deck for signs of wear or lifting of the fiberglass. Clean the surface and apply a new coat of sealant every few years to maintain its durability.
Fiberglassing requires precise work and sometimes special tools, so if you’re not confident, it might be wise to hire a professional. But if you’re up for the challenge, it can be a rewarding DIY project that extends the life of your deck significantly!
