Reseal Your Asphalt Driveway
Wash and Clean the Driveway
Rinse the driveway with the stiffest stream of water possible; pressure washers are preferred, but the brass nozzles from the garden department are acceptable. Wash all the dirt, dust, and debris off the driveway. Get rid of all the grease and oil spots/stains as these will "bleed or bubble" through the new coating. Scrub them with a stiff wire brush and the asphalt and concrete cleaner.
Fill Cracks and potholes
Use asphalt driveway crack filler to fill cracks less than 1/4" wide and deep. Fill the crack to level with the driveway. For splits and holes over 1/4", please use pothole filler (holes over 1" in depth and/or 8" in diameter need to be allowed to cure completely 30 days in sunny hot July or 90 days at other times before the application of the sealer). Fill the hole to level with driveway, pack or "tamp" down as much as possible, and refill to level. This will minimize shrinkage before you topcoat with the sealer.
Mist the Driveway
After the cracks and potholes have all been filled and the oil/grease spots have all been scrubbed, (usually 8 24 hours depending on temperature and humidity level), lightly mist the driveway immediately prior to applying your driveway coating. This will help the product bond quickly to the driveway, and dry an even colour.
Apply the Driveway Coating
Ensure driveway sealer is well mixed, using a wooden paddle or drill mounted mixer. Starting from the highest part of your driveway, apply a thin coat of driveway sealer using a roller for acrylic-based products and a squeegee for asphalt-based products (rollers are not the correct applicator for asphalt-based products as sand catches on the roller and will not adhere to the driveway. Warranties are voided when rollers are used with asphalt-based sealers). Apply sealer no thicker than a dime per coat. We recommend pulling the sealer with a squeegee while applying steady down pressure (you don't want a thick coat as it may track). For a more durable finish and even colour, once the first coat has dried to the touch (usually 2 hours), you may apply a second thin coat at a right angle. Do NOT apply sealer if rain is forecast in the following 24 hours, if the temperature will drop below 10°C in the same 24 hours, or if the surface of the driveway is still below 10 °C. Please read manufacturer's instructions prior to applying.
