Product Description

Palatine Hull Blacking is a bitumen based coating designed to be applied directly to the hull of a boat. The coating provides protection from water and weather, preventing the hull from becoming worn and damaged from everyday use of the boat.

Palatine Hull Blacking is suitable for narrowboats, cruisers and other types of inland waterway vessels. Please note that as this is a bitumen based coating, it can only be overcoated by other bitumen based products. The bitumen based hull blacking will bleed through standard oil and water based paints.

Our friendly technical team are available to contact by phone or web chat during our opening hours, where we can answer any questions you may have. This includes topics such as surface compatibility, preparation and application. Outside of our opening hours, you are welcome to send an email, which are checked each working morning.

We also have a range of other marine coatings available, such as our Marine Satin and Gloss topcoats. These are available in a variety of colours and are suitable for use on a range of different surfaces, including wood, metal, concrete and GRP.

We also supply an Marine Anti-slip Paint, suitable for wooden, metal and concrete floors, step and ramps. The textured surface makes areas safer for foot traffic, especially in wet weather or areas near the water.

Coverage / Drying Times:

Theoretical Coverage: 7 – 10m² per litre depending on surface to be treated. It is recommended to apply 2 coats.

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

Surface dry: 2 – 5 hours.

Drying time will vary according to temperature and humidity e.g. the drying times quoted will be significantly longer in cold, damp conditions.

Storage: Stored in good condition and in original un-opened containers has a shelf life of 12 months

Thinning and Cleaning: Use Palatine White Spirit.

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


Proper surface preparation is essential for the success of any protective coating system. Before you begin ensure the area is free from any dust, oil, grease, old coatings and surface contaminants.

For maximum protection prime bare surfaces with Palatine Zinc Rich Primer or Palatine Metal Primer.
For non-ferrous metals use Palatine Fast Dry etching primer.
Rub down previously gloss painted surfaces with fine waterproof abrasive paper and rinse thoroughly.


Best results are obtained in warm (minimum 10°C), dry conditions.

It is recommended that 2 coats of Palatine Hull Blacking should be applied by:

Conventional or HVLP spray.
Roller, Brush or Dip.

Mix thoroughly for approximately 2 minutes using a drill stirrer. A wooden batten at least 25mm wide is also ideal.
Apply an even coat using a brush, short to medium pile roller on smooth surfaces and a long pile roller on textured surfaces.
For spray application by either airless or conventional spray a dilution ration of no more than 10% is recommended with Palatine White Spirit by volume.
A minimum of two coats is recommended.

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.
