Application Tips for Gilsonite Sealers

• Apply in dry weather above the minimum temperature
• Clean surface of dirt and oil
• Prime oil spots
• Apply two thin coats rather than one thick coat
• Keep traffic off until cured
• Avoid application on new asphalt until it has aged enough

Best conditions

• Air and surface temperature above 10 °C and rising
• No rain expected for at least 24 hours
• Low humidity for emulsions

Preparation

1. Sweep and blow the surface clean.
2. Remove vegetation from cracks.
3. Treat oil spots with a primer.
4. Fill cracks and repair potholes first.

Application

• Stir sealer thoroughly before use.
• Apply with a squeegee or spray in thin, even coats.
• Work in sections and keep a wet edge.
• Allow the first coat to dry before the second.

After application

Barricade the area and keep vehicles off until the sealer has cured – often several hours, longer in cool weather.
