Product Description

Carbosil Marine Varnish is a hard wearing gloss varnish designed for use in marine environments. It protects wood and other surfaces from damage such as scuffs and scratches, as well as long term exposure to weather. Varnishing wood on boats and marine surfaces is important, as it can otherwise quickly deteriorate from exposure to water and weather.

Palatine Paints are a manufacturer of paints and coatings, not just a supplier. This is a product we have formulated and made internally, giving us an in depth technical knowledge of the varnish. We have ensured that this varnish is tough enough to withstand the conditions expected of a marine environment.

Our technical team are available by phone or web chat during our opening hours to answer any questions you may have, including queries on surface compatibility, preparation, application or the amount of varnish required for your project. You can also contact us by email, where overnight messages are checked each working morning.

On previously painted surfaces, ensure it is sound and non-flaking. Abrade the surface preferably by mechanical abrasion to provide a “key” and maximise adhesion of the subsequent coating. For metal surfaces the standard grades of cleanliness for abrasive blast cleaning in accordance with BS EN ISO 8501-1[1] are:
Sa 1 – Light blast cleaning
Sa 2 – Thorough blast cleaning
Sa 2½ – Very thorough blast cleaning
Sa 3 – Blast cleaning to visually clean steel


Stir the paint with a drill stirrer or wooden baton at least 2” wide. Continue to stir during application to avoid thickening of the product.
Apply by brush, roller or spray and work well into the surface. Avoid applying the paint too thickly to avoid delaying drying times. The second and subsequent coats can be applied as soon as the first / preceding coat is dry usually after 12-24 hours, and should be applied within 5 days. If more than 5 days elapse, the first coat should be lightly abraded before the second coat is applied. Avoid power washing the surface for 7 days.

Thinning and Cleaning: Use Palatine White Spirit.
