KEELBLACK is the hardest single-pack bitumen blacking available - anywhere
Protecting steel hulls against abrasion and keeping your hull smart
KEELBLACK has been demonstrated in laboratory tests to outlast 2 pack epoxy at a fraction of the cost
TECHNICAL INFORMATION
Non-toxic, water-based bitumen emulsion – environmentally friendly when dry
Fabricated from the hardest bitumen that can be emulsified, completely inert once cured
Protects the underwater parts of your boat from corrosion
Proven to outlast 2-pack epoxy, abrasion-resistant, easy to repair minor mechanical damage and
significantly less expensive than other quality bituminous paints
Deters marine growth
KEELBLACK contains no biocides but fresh water barnacles seem to dislike the super-smooth surface and weed is not attracted to the KEELBLACK coating, improving fuel efficiency and maintaining your hull appearance. Any weed that may adhere is easily removed with a brush
Reduces time in dry dock
KEELBLACK used as part of your maintenance regime shortens preparation time in dock on average by one to two days by reducing power washing, scraping and wire brushing requirements and drying time; hulls can be over-coated in the same day and relaunched as soon as dry and cured
PRACTICAL INFORMATION
Easy to apply with paint-pad, roller or brush
With a viscosity of close to 1, KEELBLACK goes easily onto primed or previously coated steel, in almost
any weather or temperature. It can flow behind any flaking previous blackings, filling voids and helping to re-adhere original bituminous coatings to the steel
Adheres to almost all previous coatings and does NOT need the surface to be completely dry
This is a huge cost saving advantage. As a cold-applied bitumen emulsion, KEELBLACK can be used on damp surfaces, eliminating the need for time-consuming drying and expensive artificial heat. It adheres to light surface rust and to most original hull coatings including bituminous paints without requiring any costly
preparation other than thorough removal of dirt and loose material
Rapid application. Three full coats of KEELBLACK can be achieved in one day
Provided THIN coats are applied, KEELBLACK can be over-coated as soon as the previous coat is
touch-dry, saving significant dock time and labour cost. Three coats are recommended. KEELBLACK
must be allowed to cure before re-launch. Dependent on humidity, 36 to 48 hours is recommended
Tough, abrasion-resistant finish and easy to repair
KEELBLACK is derived from the hardest grade of emulsified bitumen and was originally developed
for repair of worn-out tarmac roads. KEELBLACK is long-lasting and, if damaged, simple to repair,
even at the waterline with excellent UV resistance to ensure good colour-match
Reduces future dry-dock preparation time
KEELBLACK makes subsequent hull maintenance programmes faster and easier by accelerating hull
cleaning time and reducing incidence of flaking paint
Non-Toxic and odour-free
For dock labour or live-aboard application, KEELBLACK has virtually no odour and, with nil VOCs, emits
no fumes. Wet product washes off the skin and makes equipment cleaning simple
ENVIRONMENTAL INFORMATION
Environmentally safe
KEELBLACK contains no biocides and once dry has no effect on the environment. The super-smooth finish is unattractive to barnacle and weed growth
When dry, KEELBLACK does not harm fish, aquatic life or plants
It conforms to EN7375 European standards on leaching into water courses and, when dry, is inert
Inert and harmless to aquatic life when dry
KEELBLACK does not harm skin and is virtually odour-free. Extensively used by national conservation organisations in water courses and sensitive areas of special scientific interest
Solvent-free
KEELBLACK contains no solvents and can be applied to damp surfaces. This reduces energy consumption
and labour costs by eliminating much of the preparation time required for solvent based products
Non-biocide formula resists marine growth
Fresh water barnacles are not attracted to KEELBLACK coated surfaces improving engine performance and reducing scraping and preparation time in dock. Any marine growth which can occur in in heavily polluted waterways easily brushes off
ABOUT US
Tuffblack Ltd is an owner-run business based in Herefordshire producing and distributing the world's hardest bitumen emulsion and the only water-based bitumen blacking specifically designed for inland waterways craft.
Manufactured to exacting standards and to a secret formula, KEELBLACK, like so many great products was discovered by accident. It was first developed as a road surface treatment for worn-out tarmac; proof against the aggressive wear and tear of high volume traffic as well as providing a strong, non-skid surface but then found to have similar strength and abrasion-resistant qualities when used on steel. With some alterations to the formula for application on ferrous and non-ferrous metals, KEELBLACK was quietly launched in 2015 and, following the 2016 Crick boat Show, has been enthusiastically taken up by the canal and river-boat community.
Owners and Operators have found KEELBLACK to be the toughest available bitumen-based blacking for steel - equally suitable for applying over old bitumen, degraded 2-pack epoxy, primed bare steel or on a new build.
KEELBLACK combines ease of application with longevity and excellent coverage at economical cost. Applied by the DIY blacker KEELBLACK costs less than £0.75p per square meter per coat. Three coats recommended
