Can you tell me the coverage of a 20lt drum of 3M Scotchkote Poly-Tech 665? I have a roof area of 24m², it is a felt and bitumen roof, would I require primer?

Ian Edwards from Liverpool (UK) - 06/01/16


Your roof should first be cleaned with a proprietary fungicidal wash such as Rust-Oleum Mathys AMW Moss Killer. Then the roof should be primed with 3M Scotchkote Poly-Tech BP Primer 656. Once dry, 3M Scotchkote Poly-Tech 665 is a two coat system incorporating 3M Scotchkote Premier 100g Reinforcing Mat 050 in the first coat. Scotchkote Poly-Tech 665 should be brushed/rolled through the reinforcing, keeping the thickness of the coating as even as possible and no thicker than is required to wet down the reinforcing. The second coat of Scotchkote Poly-Tech 665 should then be applied using a good quality brush or roller a minimum of 2-4 hours after the first coat. Adjacent widths of reinforcing should allow 1-2cm overlap. You will achieve around 20m² per 20lt on the first coat with reinforcing and approximately 60m² per 20lt on the second un-reinforced coat.
