When can you Sealcoat a Parking Lot?

Sealcoat is beneficial for several reasons: aesthetics, durability, maintenance, longevity, waterproofing, and more. However, as we have said before, sealcoat can only be applied if certain conditions are met.

When can you Sealcoat a Parking Lot?

  1. Temperature: We have addressed temperature several times, but here we go again. Sealcoating should only be applied if both ambient temperature and pavement temperature are above 50°F and below 85°F.
  2. Asphalt Defects: Any cracks, pot holes, or other forms of asphalt damage should be properly repaired before sealcoat is applied.
  3. Clean Surface: In order for the sealcoat to bond properly to the asphalt, the surface must be cleaned, removing dirt and debris. Just remember this old saying: “a coating is as good as the surface that it is applied on.”
  4. Oil Spots: Sealcoat will simply not bond correctly to oil spots. Because of this, spots should be addressed before application.
  5. Asphalt Age: It is recommended that you wait at least 4-6 weeks after laying fresh asphalt before sealcoat is applied. To ensure the pavement is ready for sealcoat, perform a a Water Break Free Test. Spread a gallon of clean potable water on the pavement. If the water sheets out, free of rainbow colored rings or beading, the pavement is ready.
