10 Quick Tips for Fibreglass Matting

The thought of working with fiberglass matting can seem quite intimidating, and can get messy if not used correctly. However by following clear, and simple directions, working with fiberglass matting can be made simple, and efficient.

Below are some simple tips for when using fiberglass matting once you have prepared your mold:-

1. Firstly prepare the fiberglass matting by cutting it to shape, and suitable sizes to cover your form. *always allow for overlap where you need to join at corners*
2. When mixing the fiberglass measure the appropriate amount of resin then add the hardener.

*Use a metal container to mix in and always go by the manufacturer’s directions (most kits will have a premeasured ‘can’ or bucket of resin and a premeasured tube of hardener).

1. Thoroughly stir the resin and hardener together *always ensure you get the sides and bottom of the container not just the middle - a paint stick is ideal for this
2. Lay the fiberglass matting on or in the form and spread the mixture with a disposable brush, the matting will appear to melt into the resin as it spreads. *Use a brush to build up the layers of the fiberglass to the desired thickness up to ¼ inch.
3. * Make sure you apply to all corners of the form – failing to cover all corners may result in weakness developing in these areas.
4. Work the mat and resin completely over your form until it is completely covered *continue working until you have used all your material.
5. Clean up all the tools and any spills before the mixture hardens *use a solvent containing acetone this is most effective as it is strong and evaporates quickly.
6. Repeat these steps until the desired thickness is achieved. *Dependent on the project this is usually 3 layers thick – no more than 10.
7. When applying new layers, try laying these in different directions, this will help make it stronger.
8. To finish apply a gel coat or smooth coat resin.
