How to coat your asphalt driveway

Preparation

• With new asphalt – simply ensure surface is clean with no contamination.
• With old asphalt – first clean by high pressure washing and simultaneously rinse off thoroughly with plenty of clean water.
• Allow to dry completely.

Small surface repairs using abe®.cote SF 356 mortar (not larger than 300 x 200mm and 20mm deep)

• Prepare mortar mix using a 2 litre kit of a.b.e.®cote SF 356 and 7 to 8 litres or +/- 13kg of a.b.e.®silica sand No 1 (approx. half of the 25kg bag)
  (Note: Thoroughly pre-stir the a.b.e.®cote SF 356 base and activator components separately, before blending them together. Never use the same mixing paddle when stirring the base and activator individually.)
• Mix the a.b.e.®cote SF 356 base and activator thoroughly for 5 minutes using a flat mixing paddle Introduce the clean dry silica sand and blend in until thoroughly wetted out.
• The desired outcome would be a stiff, yet workable and trowel compactable repair mortar (this mixture would yield approximately 6,7 litres and would be enough to repair 4 number 200mm x 300mm size holes of approximately 25mm deep).
• Once all holes have been filled, allow to cure for approximately 12 hours (timing is temperature dependant). After this proceed with coating the entire driveway.

GOOD TO KNOW:

The product is initially shiny but eventually dulls to a matt black which is easy to clean, resists oil and many other substances which are potentially damaging to normal asphalt.

Coating Asphalt driveway

• Mix a.b.e.®.cote SF 356 for 5 minutes as before (but no addition of sand this time).
  (Note: Thoroughly pre-stir the a.b.e.®.cote SF 356 base and activator components separately, before blending them together. Never use the same mixing paddle when stirring the base and activator individually.)
• After the base and activator have been mixed together pour the product into several paint trays to reduce bulk volume and thereby avoid exotherm (heat generation and accelerated setting).
• Then immediately spread, roll out onto surface using squeegee or roller. Spread rate and consumption will vary depending on surface profile and thickness desired (approximately 0,5 to 1,0 litre /m2 consumption is average).
• If a slip-resistant surface is preferred, this can be obtained by broadcasting a dry silica grit of desired coarseness into the still wet coating.
• When working on asphalt surfaces never dilute the a.b.e.®.cote SF 356.
• Driveways longer than 6 m would require a separation break in coating continuity at maximum every 6 metres centres. This break can be as narrow as a 6 mm wide strip.
• Protect coated surface from traffic and allow curing for 3 days. Curing of the surface at 25 °C normally could have foot traffic after 24 hours, vehicle traffic after 3 days, and full cure is reached at 7 days.
