Questions and Answers: Restoring Old Gelcoat Surface on Boats
Why do I need to maintain the gelcoat surface of my boat?
Composite materials, like fibre glass, having an exterior layer of gelcoat are used to make boats. The gelcoat surfaces are made to be long-lasting, with resistance to UV damage and hydrolysis. And it's not just about how the surface looks when it's restored. Fixing cracked surfaces will also protect the boat from salt, filth, mould, and excessive moisture.
Can you restore gelcoat surface on a boat?
Yes, you can, by regularly waxing the gelcoat surface you can prolong the lifetime of the gelcoat on your boat for 15 years or more. Keep your boat looking great for a longer time by using quality products.
What is oxidation on a gelcoat surface on a boat?
If the surface on a boat is not maintained properly, it gets a chalky, porous appearance. The main cause of oxidation are UV rays which slowly break down the surface and damage unprotected gelcoat.
I recommend Mirka’s Polarshine marine products to anyone who really wants to take care of their boat. The result is amazing, 42-year-old Emma looks new again. I was surprised by the ease of work.

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.
