Fibreglass Boat FAQ'S
Click a question to reveal the answer!
A: No, I am afraid that you cannot use gel coat to enhance the finish on your boat. Gel coat is very difficult to apply smoothly and burnish up. The best product to use is a 2 pack polyurethane (which you can purchase from a chandler) or a 2 pack acrylic which can be purchased from a good car paint supplier).
A: To create a "smooth finish" on your repair I recommend that you use flow coat. This is gel coat with a wax additive that can be used on the surface of your boat to blend in the repair. Flow coat is available in numerous colours (we have stock if you would like us to send you some).
A: I would recommend that you use a 2 pack polyurethane paint or a 2 pack acrylic paint which can be purchased from a good car accessories/paint shop.
A: We would recommend that you use fibre glass tape and epoxy resin (tape is available in various widths - 25mm - 150mm and the epoxy is available of the shelf in packs from 500gms to 6.0kg (all available from our factory shop). In extreme weather conditions you may have to put a heater in the garage while doing the repair.
A: Materials that you would require are: Resin and Hardener, chopped strand mat, laminating brushes, buckets, acetone, metal roller (if you pass me your email address and mailing address I can send you a price full list of materials available at our factory shop). To start work: Abrade and wash the area to be laminated. Cut the glass fibre to the required size. Mix resin and hardener (you will need approx./ 1 litre resin to 1 square metre mat, Paint over the area to be patched with the resin. Lay 1 layer of glass fibre over the area and wet out with the resin. Lay 2nd layer and wet out. Roll the area with a metal roller to consolidate and allow to harden.
A: No this will not be caused by release agent. The possible cause could be rust from a support frame or the gel coat has been repaired in that area. Rub down with 800 or 1000 wet and dry paper and compound the area infected.
A: Prout Catamarans started in this way and built the first catamaran in the UK. I can't see any problems with your idea.
A: There is no "normal" moisture level in glassfibre boats. If you have a moisture reading of any description this would normally dry out when the boat is taken out of the water each season. If this is not the case I would say that there is a possibility that osmosis is present (this means that the water has penetrated through the gel coat into the fibre glass matting).
A: My apologies but I would need to survey this type of problem before suggesting any solutions.
A: Yes, this sounds like osmosis. If you break a blister it will taste and smell like horrible vinegar. This can be repaired at a cost of approx. ?100 per ft. You need to consider 2 things: Is the boat worth spending this kind of money on and how many more years do you want out of the boat!
A: The best type of paint to use is a polyurethane 2 pack.
A: I cannot answer this question fully, I would need more information, please call our offices for an informal chat.
