BLACK DOG BITUMEN

A high performance full- bodied bitumen paint formulated for the anti-corrosive protection of the underwater hulls of canal boats, drying to a mid-sheen finish. Bitumen is often known as “blacking” and is commonly used for canal boat maintenance. Our Black Dog Bitumen paint gives protection in both salt and fresh water to maximise longevity of the finish and provide the ultra-durability. The finish has abrasion resistance and high flexibility to minimise the risk of damage and cracking, and has superb weather resistance for those areas exposed to above water.It is resistant to low concentrations of alkalis and acids, and can withstand prolonged oxidation.

FEATURES

• High build application to reduce time and cost

• Produces a hydrophobic, elastic membrane for below the water line

• Very strong adhesion to most types of substrates

• Excellent mechanical and chemical resistance properties

• It is ideal for application onto vertical surfaces with no running or bubbling

PREPARATION

Preparation of the surface is of great importance and will influence the adhesion attained and the life of the coating. All surfaces must be sound, stable and thoroughly clean and dry. Metal surfaces should be wire-brushed to remove rust. Where long-term protection is essential, an initial treatment of a rustinhibitive product should be used. Loose or blistered paint should be removed, as should tar-based paint systems. New galvanised surfaces should be roughened with a wire brush or treated with a proprietary etch primer. Porous surfaces should be primed beforehand.

APPLICATION

Black Dog is ready for use and should not be thinned. Stir thoroughly before use. Apply by brush, roller or spray. A minimum of two coats should be applied. The first coat should be allowed to dry (normally 2-4 hours depending on weather conditions) before the second coat is applied. Concrete and some stone surfaces may be porous so an initial primer coat should be applied
