HOW ARE BRUSHES AND ROLLERS USED?

Woven glass fibre sheets are strategically placed in a mould. A bonding resin which is usually polyurethane or epoxy is then applied. Brushes and rollers are used to apply the resin to the fibreglass layer by layer until the correct depth is achieved. Brush bristles are constantly used during the procedure to expel air by prodding the viscous applied resin.

The resin itself is highly viscous and has a short open time. (Dries quickly. 5-15mins.) Brushes and rollers are soon rendered ineffective due to the fast drying resin. This means that many brushes and rollers are used in the fibreglass process.

BRUSHES AND ROLLERS DESIGNED FOR GRP PROCESSES. (FIBREGLASS.)

Paint Brushes.

 In order to manage costs a range of economy wooden handle brushes with natural bristle are most commonly used. These are available at BARFI in 6 sizes from 1in – 4in. A slightly more expensive range of bristle brushes with plastic beaver tail handles are also available in all sizes from BARFI. Brushes can be cleaned using acetone but this can be more expensive than replacing the brush.

Resin/Gel application roller.

Resin can also be applied using a roller. For this specific function we have created a crimped nylon roller with 13mm nap. This nylon fabric is thermo fused to a plastic core and is designed to take a good load and perform very well with highly viscous resins. It also works more effectively for longer than all other products in this field bringing good value for money. This product is available in 3 sizes from 100mm, 150mm and 25cm. Nylon rollers can be cleaned from resin using acetone.

Top Coat Roller.

Finally when the product is manufactured it is finished off with a gel-coat otherwise known as a top-coat. Velour rollers are the most common, effective and efficient way of applying a top coat leaving a good finish. The velour natural wool fabric is applied by thermo fusion to a plastic core. The nap length and density is ideal to apply a thin even top coat with an excellent finish. It should be noted that felt and microfiber can also be used to apply this final finish.
