Step 3: Prepare the Resin and Hardener

Follow the instructions on your chosen resin and hardener carefully. Typically, you'll mix the two in a specific ratio to create a strong bonding agent. Stir the mixture thoroughly to ensure a consistent consistency, avoiding any lumps. Allow the resin to sit for a short period, as this can help it become more workable.

Step 4: Apply the Patch and Resin

Lay the fiberglass patch over the damaged area, ensuring it covers the entire affected zone. Use the brush to gently spread a thin layer of the mixed resin over the patch and the surrounding area. This initial layer, known as a 'gel coat,' provides a smooth surface for the patch to adhere to. Allow the gel coat to set for a short time, following the resin's instructions.

Step 5: Secure and Smooth the Patch

Once the gel coat has set, carefully lay the non-woven glass cloth over the patch, ensuring it is taut and smooth. Use a rolling pin or a similar tool to apply firm pressure and adhere the cloth to the resin. This step creates a strong bond between the patch and the existing fiberglass. Smooth out any wrinkles or bubbles using the back of the brush or a putty knife.

Step 6: Allow for Curing

After securing the patch, leave it undisturbed for the recommended curing time, which can vary depending on the products used. During this time, avoid any pressure or impact on the repaired area. Once cured, the patch should feel firm and integrated with the surrounding fiberglass.

Remember, this process requires patience and attention to detail. Take your time to ensure a clean and effective repair. With proper application and curing, your fiberglass boat deck can be restored to its original strength and appearance.
