With the rust addressed, it’s time to patch any holes in your lawn mower deck using the Fastglass Glass Fibre Kit. Cut strips of glass fibre from the kit and place them over the holes, ensuring they cover the entire damaged area. Apply the provided resin to the fibre strips, using a brush to evenly distribute the resin. Be sure to build up layers if necessary, allowing each layer to dry before adding the next.

Step 4: Allow the glass fibre to harden

Once the glass fibre and resin have been applied, allow them to harden completely. This usually takes a few hours but can vary depending on the temperature and humidity in your area. Check the manufacturer’s instructions for specific drying times.

Step 5: Sand down the repaired area

Once the glass fibre has hardened, you can begin sanding down the repaired area for a smooth finish. Use sandpaper with a medium grit and gently sand the patched section, blending it in with the rest of the deck. Take your time and ensure the repaired area matches the surrounding surface.

Step 6: Prime and paint the deck

Finally, it’s time to protect your lawn mower deck from future rust by priming and painting it. Apply a high-quality primer to the entire deck surface, following the manufacturer’s instructions.
