A black, thick, heavy duty asphalt primer applied before Heavy duty roof Coating or Aluminium Roof Coating on dry asphalt & felt roofs. It penetrates and revitializes the asphalt and replaces some of the waterproofing oils lost by exposure to the sun. It provides a better bonding surface for the roof coating and insures that the coating stays otop of the surface for greater protectioand long lasting waterproofing.


Tin size: 25 litres.
Coverage: surface dependant - between 0.31 litres per m2 and 1.22 litres per m2.
Equipement: brush, broom, airless spray equipment  (we prefer 9” deck scrub broom).
Curing: Can be applied in almost any conditions, but dry is always best for optimal results.
Finish: black.


Applied straight from the container with standard roofing brushes, squeegees, rollers or airless spray equipment. Requires no heating, thinning or mixing.

Curing time

Drying time depends upon temperature and climate. Allow to dry tack free before application of heavy duty. Usually dries to touch in 12 hours or less. Must weather a minimum of 30-60 days before application of SWEPCO aluminium roof coating.

You may also require a Heavy Duty Patching Compound & Patching Fabric to repair any large cracks/splits in the roof surface as well as a SWEPCO Roof Coating System. If you are unsure what products you require please feel free to contact us on : 01752 692760 for further assistance.
