GRP Repairs

JWS Marine Services has earned an excellent reputation for performing boat fibreglass repair and fabrication. The key to quality marine fibreglass work is preparation and quality materials.
With over 22 years of marine fibreglass experience, we produce consistent high-quality work. At JWS Marine Services, we are constantly working with manufacturer reps to stay abreast of the newest marine fiberglass products and processes.
The combination of high technology materials, extensive preparation and years of experience results in high-quality and competitively priced services for our customers.
We are not just limited to boats, we carryout a number of repair to jet-ski and even a couple on caravans.

Work Process

Different depths show different colours, therefore to provide a seamless finish, new gel coat must be colour matched at all levels.
Surface scratches can be buffed out of gel coat, using a polishing compound, but deeper scratches must be filled.
When the gel coat surrounding a scratch is in good condition, the filler of choice is gel coat paste, which provides both filler and finish in a single application but not in a single action. This is because the surface of cured gel coat will be uneven therefore sanding/polishing is required to smooth the repair and to blend in the rest of hull. The filling and fairing of the damaged area is the easy bit, colour matching is another story.

Colour Matching

Colour matching the gel coat is the hardest part of a gel repair. Professionals who carry out this work on a daily basis still have difficulty in getting a perfect match and in some cases even the ‘factory’ colours don’t match exactly, if the boat has been in the sun for a few years and fading generally occurs over time. White gel coat has a significant advantage of being fairly easy to match once a small repair is buffed out, shading differences are unnoticed. Matching coloured hulls is somewhat more of a challenge. 

Here at JWS, we will continue to colour match until we are 100% happy with the hull colour match.

With an array of colours to choose from including not just 1 but 5 shades of white JWS are confident we can match your colour.
