Suregrip Anti-Slip Deck Paint
Teamac Suregrip is a ready mixed anti-slip (non-slip) paint which contains special coarse aggregates which gives an anti-slip coating to a wide range of surfaces.
Suregrip can be used as a safety coating in areas where a sure foothold is required.
It is suitable for wood, metal, concrete and glassfibre surfaces.
Once applied Suregrip dries fast to give a glossy bonded surface which is both durable and decorative.
Suregrip helps prevent slips, trips and falls.
Ideal for use by fishermen, yachtsmen and all seafarers on boats, pontoons, marinas, quaysides and ramps etc.
Teamac Suregrip anti-slip's theoretical coverage rate is 6 - 10 m2 per litre.
