Paint smoothing over marine varnish and top coat

Maintenance of varnish and top coat on yachts and other vessels

Building and maintaining the perfect yacht or other vessel takes time, effort and knowledge. At the manufacturing stage, Mirka marine solutions can increase the productivity of surface finishing processes and ensure a better end result.

A better quality of surface finish and coating can be achieved by sanding, polishing or removing minor imperfections such as orange peel effect for even more shine.

Marine topcoats can be applied after surface preparation to ensure adhesion to the substrate and provide a long-lasting, weather-resistant finish. Mirka offers solutions for both fresh and fully cured topsoil.

Q&A: Clearcoat and Topcoat for Boats

Can the top layer be used on a yacht or other vessel?

Topcoat is a marine finish that can be used above and below the waterline. Marine topcoats should be applied after the surface has been well prepared to ensure adhesion to the substrate and to provide a long-lasting finish that will withstand a wide range of marine weather conditions.

What is the difference between gel and clear topcoats for yachts and other boats?

Gel and topcoat coatings vary in thickness. Gel coat is a layer of resin that is poured into the mold before casting. A clear coat is a very thin layer of varnish that is applied to the part after it has been formed.

For Finnish yacht builder Nautor, high-quality finishing is a tribute to the company's roots and heritage, and requires the best power tools and abrasives.

A better choice for you and the environment. Water-based polishes.

All Mirka polishes are water-based and manufactured in Finland. Water-based polishing compounds have many advantages.

• Effective long-term scratch removal - water-based compounds remove scratches permanently. Solvent-based compounds can lose their luster after degreasing the surface, and in some cases only temporarily hide scratches.
• Safer for the user - no dangerous chemicals
• Sustainable – Water-based polishes are more environmentally friendly because they do not contain benzene or similar hazardous chemicals.

"Solvent-based polishes may be effective in the short term, but they are more damaging and damaging." - Kim Rönnholm. Portfolio Manager, Mirka.
