Applying fiberglass or tape to a surface is an essential step for reinforcement and abrasion resistance. Fiberglass application Malta boat builders and repairers rely on is widely used across marine, automotive and construction work. That’s because the finished result is both durable and protective.
When Fiberglass Cloth Gets Applied
Fiberglass cloth typically goes on after fairing and shaping, and before the final coat. It can be laminated in multiple layers, and combined with other materials, to build strong composite parts rather than a single thin skin.
There are two main application methods: dry and wet. The dry method applies cloth over a dry surface. The wet method places cloth onto an epoxy-coated surface instead. Since positioning is trickier with the wet method, the dry method tends to suit thinner cloth applications better.
Dry Method: Applying Fiberglass Cloth or Tape
- Surface preparation: prepare the surface as you would for epoxy bonding generally.
- Positioning the cloth: cut it several inches larger than the intended area. On a large surface, overlap multiple pieces by about two inches instead. Use masking tape, duct tape or staples on vertical or sloped surfaces.
- Mixing epoxy: in practice, that’s a small batch, typically three or four pumps of resin and hardener.
- Applying epoxy: pour a small amount at the centre of the cloth and spread it with a spreader, or use a roller or brush on vertical surfaces. Properly saturated fabric turns transparent; white patches mean it’s still dry.
- Avoiding air bubbles: excessive squeegeeing traps air in the epoxy, so it’s worth going easy on the pressure.
- Trimming excess cloth: once the epoxy reaches its initial cure, trim excess fabric with a utility knife. In particular, overlapped areas can be trimmed and re-wet for a seamless finish.
- Final coating: apply additional epoxy coats to fill the weave of the cloth before final sanding.
Wet Method: Applying Fiberglass Cloth or Tape
The wet method places fiberglass cloth onto an epoxy-coated surface. It’s not always the preferred approach, but it suits specific applications well.
- Surface preparation: ensure the surface is clean, and pre-fit the fiberglass cloth beforehand.
- Applying epoxy: roll a heavy coat onto the surface.
- Placing the cloth: unroll it over the wet epoxy and position carefully. In particular, thickening the epoxy with a filler helps with adhesion on vertical or overhead surfaces.
- Removing wrinkles: smooth them out using a gloved hand or a squeegee.
- Second epoxy layer: apply a second coat to fully wet out the fabric.
- Trimming and finishing: once the epoxy reaches initial cure, trim excess cloth and re-wet any raised edges. Then add further coats to fill the weave before final curing.
Clear Epoxy Finishes Over Wood
For a clear finish, use a short-bristled brush and apply epoxy in light, even strokes. Avoid overworking it, since that traps air bubbles too. If the epoxy turns milky from high humidity, lightly warming the surface with a heat gun or hairdryer usually clears it.
