Sealcoating

Sealcoating is the ‘sunscreen’ for existing asphalt. In the same way that sunscreen serves to protect, not cure, the skin from sunburns, so too does sealcoating protect your asphalt surfaces instead of curing any superficial cracking or damage. The gray, oxidized look of an asphalt surface is an eventuality due to time and harsh environmental factors like rain and prolonged extreme temperatures. Sealcoating restores the asphalt’s appearance to the fresh, black look of a recently paved surface.

What is Sealcoating?

Sealcoat is an asphalt emulsion which is mixed with water and an aggregate (usually sand) to create a lightly textured surface and help the emulsion be absorbed by the asphalt. Depending on the last time the surface was previously sealed, the ratio of water to sealer can be adjusted to ensure the proper coating is achieved. Sealcoating leaves an asphalt surface looking like freshly paved asphalt

How is Sealcoating Applied?

Sealer is applied in either a spray coat or a squeegee coat, depending on which method best serves the area to be sealed. Regardless of which method is used to apply the sealer, the process is the same:

  • If any Asphalt Repairs are necessary, they must be performed first and allowed to fully cure before sealcoating
  • Barricades and string line are used to cordon off the area where sealer is going to be applied to prevent disruption to the surface
  • Large blowers and brooms are used to clean the area of dust, dirt, debris and other detritus
  • In areas where there are oil stains that have not penetrated deep enough to necessitate repairs, a petro-bond is applied to the surface to ensure the sealer adheres to the oil-stained asphalt
  • Sealer is either sprayed or squeegeed onto the surface. Intricate areas such as around car stops, curbing, or non-asphalt materials such as paver bricks always have the sealer applied via squeegee
  • On projects that require a second coat, the first coat is allowed to dry (usually 3-5 hours) before the second coat is applied
