Gelcoat Mould Sanding and Polishing
Preparing and Finishing Moulds in Boat and Yacht Production
Facing harsh conditions with salt, water and wind, marine surfaces need to be built to last. It all starts with the hull and for that, you need a plug and mould to construct a frame that gives the boat or watercraft its shape and strength.
One of the keys to success in mould construction is proper surface preparation of the plug. Any imperfections on the surface will be transferred to the mould, and then to future parts made from that mould, meaning corrective work and a high standard of finish is more important than ever. In addition, a smoother outer surface on the mould will require less work on the finish.
With Mirka’s net and multihole abrasives, ergonomic sanders and efficient dust extraction, you can work faster and more efficiently while improving work safety.

Process steps
Prepare for Success – Why Surfaces Matter When Creating Moulds
Why do you need to have a consistently smooth surface on a mould?
There are two types of moulds, male and female. Male moulds are faster and cheaper to make. Each part produced will have a rough outer texture that will need more work on the finish. Female moulds are often more expensive, but they require less work on the finish because every part gets a smoother outer surface.

Water-Based Polishes
All polishes that Mirka produces are water-based and produced in Finland. There are many benefits of choosing a water-based polishing compound.
- Effective permanent removal of scratches - Water-based compounds remove scratches permanently. Solvent-based compounds can lose gloss after cleaning the surface with a degreaser and in some cases, they may only temporarily hide the scratches.
- Safer for the operator - No hazardous chemicals
- Sustainable - Water-based polishes are better for the environment and do not contain benzene or similar hazardous chemicals.
Solvent-based polishes may be effective in the short run, but they are more damaging and harmful.
