- Which boat lacquer to choose? -
Top coats are divided into one-component and two-component lacquers. 1-component boat lacquer is cheaper and easier to apply, but must be reapplied more frequently due to its consistency. 2-component boat lacquer consists of a base coat and a hardener. These components must be mixed before use. Two-component lacquers are much more durable and keep their gloss for 6-8 years, which is better than one-component products (approx. 2-4 years).
Never apply 2-component boat lacquer to 1-component paint! If you are not sure what type of boat lacquer is on your hull, we recommend soaking a small cloth with 2K thinner and placing it on the hull somewhere out of sight. After a few minutes, check carefully whether the paint can be easily removed (e.g. with a spatula or a pocket knife). If so, one-component lacquer has been used. Make sure you only use 1-K boat lacquer again!
If you are going to apply boat paint directly to the gelcoat, a 2-component lacquer is recommended due to its hardness. A compatible 2-component primer should first be used. If it is not a new boat, be sure to remove any unevenness before applying the lacquer.
If your existing boat paint is still intact and only needs to be refreshed, you can simply reapply with another coat. It is essential to repair deep scratches and damage beforehand in order to obtain an even coat of paint. The old layer should be lightly sanded for better results.
If the old boat paint can no longer be used, it must be completely removed. The best way to do this is to use a hot air gun and scraper. Start painting again from your boat's gelcoat.
Corners, edges and small parts should first be painted with a brush. Large areas are easiest to paint with a roller. When applying boat paint, always work horizontally with the roller in order to reduce the risk of dripping and to achieve better coverage. Be careful with 2-component lacquers: Never use foam rollers!
