Paint Rectification on Marine Clear and Topcoat

Clear and Topcoat Process for Yachts and Boats

It takes time, effort, and knowledge to build and maintain the perfect yacht or boat. At the manufacturing stage, Mirka's marine solutions can make the surface finishing processes more efficient and with a better end result.

The quality of the surface finish and coating can be taken to the next level by sanding or polishing, or removing smaller imperfections such as orange peel, to get an even better lustre.

Topcoat marine paints can be applied after surface preparation to ensure that the topcoat paint adheres to the substrate and provides a long-lasting finish that can resist a variety of weather conditions. Mirka provides solutions for both fresh and fully cured topcoat surfaces.

Questions and Answers: Clear and Topcoat for Marine Applications

Can you use topcoat on a boat or yacht?

Topcoat boat paint is a marine finish that can be used both above and below the waterline. Topcoat marine paints should be applied after extensive surface preparation so that the topcoat paint adheres to the substrate and provides a long-lasting finish that can resist a variety of rough weather conditions on the sea.

What is the difference between gelcoat and clearcoat coatings on yachts and boats?

The difference between gelcoat and topcoat coatings is in the thickness. A gelcoat is 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.

A better choice for you and the environment

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.
