Creating a simple box shape with GRP fibreglass in a melamine mould

For fibreglass moulding projects you will, in most cases, need to have a fibreglass mould. However, if the project is of a simple shape made of mainly flat surfaces such as a box, hatch lid and even projects as large as a boat wheelhouse, it is possible to manufacture these without a fibreglass mould. Fibreglass will de-mould easily from a melamine surface, so it is ideal for constructing simple moulds. This is an excellent way also to make a one-off use mould without the expense of making a master/plug and then a fibreglass mould. We have linked the products used throughout the following step by step process.

Takes longer to let 1st layer cure, when each layer is just as easy as the first

Hi, Great video, thank you for posting. I'd like to make a fiberglass box for my boat. What is the name of the board you use to add thickness to your construction? Thanks a bunch.

Was that 1 layer of 1oz and followed by 2 layers of 1 1/2 oz mat ?

What did you do with the rest of the catalysed white gelcoat, that you didn’t use in the mould ?

How can I get some of your tools in Ghana west Africa

Shouldn't the resin be tacky rather than fully cured between layers?

Hi
What is the aprox material cost for this project, not counting the mold

Many thanks

Hi guys, just wondering do you change the resin for the final coat. I take it you use a laminating resin and gelcoat to start off with. Do you add wax to the final coat to allow it to fully cure? Thanks

WHITE RESIN LOOKS MUCH BETTER THAN YELLOW RESIN.

Unusal technique, looks like you used gelcoat or pigmented resin for the bulk of the layup.

How harmful is it to human health Wax, PVA, Gelcoat and polyester resin, and is there any problem in working without protective mask ever.

Fibreglassing good but having a solid unvented door with a gas meter behind cant be legal. Also any gas leak will fill the wall cavity. Yes, they are not made to leak. And ships are not made to sink are they? Glad I don't live anywhere this.
