About Us

Tuffblack Ltd is an owner-run business based in Herefordshire and sells 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 the same 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.

They 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 £1.00 per square meter per application.
