Questions and Answers: Condition of Factory Gelcoat Coating Is Important for the End-Result
Why do you need a good condition gelcoat surface on a yacht?
Factory gelcoat coating and its condition is important. Composite materials, such as fibre glass with an exterior layer of gelcoat are used in manufacturing of boats and yachts. 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 maintained. Preventing cracks or refinishing a cracked gelcoat surface will also protect the yacht or boat from salt, filth, mould, and excessive moisture.
What is the difference between gelcoat and clearcoat coatings on yachts and boats?
The difference between gelcoat and topcoat coatings is in the thickness. Gelcoat is harder and provides more efficient protection of the surface from the harsh conditions at sea.
Topcoat also protects the surface, but is sometimes used for more aesthetical reasons. In the boat or yacht production process a gelcoat consists of a coating of resin that is poured into the mould before doing the lay-up.
Clearcoat is a very thin layer of varnish that is applied to the part after it has been demoulded.
Steady grip. Less than 3.2 kg. High flexibility.
Mirka® Leros-S. Reach Closer.
The Mirka® LEROS-S features the well-known abilities of the LEROS, but in a shorter, even more easily handled length. That makes it perfect for sanding larger areas faster, such as on yachts and boats. The LEROS-S has two dedicated grip points for full control.
Thanks to its lightness, balance and easy manoeuvrability, the LEROS-S makes it possible to sand large areas faster and easier. The large sanding pad with its 5mm orbit works especially well in levelling filler.
It features a highly flexible sanding head to make sanding easier and more ergonomic. A better working position makes sanding more effortless and improves the end result as well as productivity.

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.
Solvent-based polishes may be effective in the short run, but they are more damaging and harmful.
