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.

If you are looking for a marine varnish in an aerosol form, please see our Yacht Varnish Spray. We also have a range of other varnishes available here. These include internal, floor and tinted varnishes.

Colours Available: Clear

Pack Sizes: 1 Litre, 2.5 Litre, 5 Litre.

Coverage / Drying Times:

Surface Dry: 3 hours

Hard Dry: 24 hours

Overcoat: after 16 hours
Keep coated areas dry for a minimum of 24 hours following application.
Please note, drying times will be extended at low temperatures. Do not apply when ambient temperature falls below 10ºC

Theoretical Coverage: 12 – 14m² per litre.

(Coverage rate can be affected by such variables as type and condition of substrate, type of application equipment and individual method of application.)


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.

Why does condensation form in my home?
Condensation forms more easily on cold surfaces in the home, for example walls and ceilings. In some cases, those surfaces can be made warmer by improving the thermal insulation. In many cases, thermal insulation is not possible due to house configuration or cost of refurbishment. An efficient way of combating condensation is to cover walls and ceilings with a specially formulated anti-condensation paint and TruTherm anti condensation paint has been formulated using the latest technology of additives.

What is the difference between anti condensation paint and thermal anti condensation paint?
Anti-condensation paint and thermal anti-condensation paint both aim to prevent condensation issues, but they work in slightly different ways:

Anti-Condensation Paint:
Purpose: Anti-condensation paint is designed to stop damp problems caused by moisture from inside the property.
Function: It creates a layer of insulation on surfaces, reducing the formation of water droplets on walls. This type of paint is particularly useful in areas prone to high humidity, such as bathrooms, kitchens, or basements.
Effect: By improving the thermal performance of surfaces, it makes them less likely to retain moisture, preventing condensation and mold formation.
Limitations: While it helps reduce condensation, it cannot completely prevent mold growth. Good air circulation, adequate heating, and ventilation are still essential12.
Thermal Anti-Condensation Paint:
Purpose: Like anti-condensation paint, thermal anti-condensation paint aims to prevent condensation, but it focuses on thermal insulation.
Function: It absorbs and holds heat longer than standard emulsions. By doing so, it prevents condensation from forming on the surface of the wall, as the heat evaporates any moisture.
Effect: The improved thermal properties keep the wall warmer, reducing the risk of condensation.
Application: Use it in areas where standard paints might struggle due to constant high humidity and moisture levels.
Note: While it helps prevent condensation, it’s essential to address root causes (such as ventilation and heating) alongside using this paint for optimal protection32.
In summary, both types of paint serve similar purposes but approach the problem from different angles. Consider your specific needs and the environment when choosing between them. Remember that no paint can completely eliminate mould growth, so proper maintenance and ventilation remain crucial.
