Sealcoating Benefits



Sealcoating Facts

Sealcoating should only be performed under the proper weather conditions.

The recommended air and pavement temperature should be at least 55  degrees Fahrenheit and rising during sealer application and for 8 hours  afterward.

Traffic should be kept off a newly sealed surface for a minimum of 18  to 36 hours to allow for drying (curing) time. If this time frame is  not practical, L&L Industries will perform or coordinate application of sealcoating in separate  mobilizations to maximize convenience. It is also important to refrain  from using sprinklers near the area, hosing down, or washing the area  for 48 hours before and after work is completed.



When covered with a dark black sealant,  pavement looks and wears like new. Parking lot sealcoating helps to  project a positive image of the company, facility, or residential  complex.

Slows oxidation and water penetration

Sealcoating fills surface voids, which  reduces exposure to oxygen and UV rays and reduces the depth to which  oil or gas can penetrate the pavement.

Sealcoating acts as a waterproofing  agent, minimizing the rate at which water enters pavement. Without it,  water can permeate more freely resulting in freeze/thaw expansion and  contraction of the pavement.

Sealcoating resists oil and gas spills

Gasoline dripping from a topped-off fuel  tank during hot weather can soften and break down unsealed asphalt  pavements. Coal tars used in sealcoat are impervious to gas and oil  spills.

Asphalt sealcoating is easier to clean and maintain

Sealcoats fill surface voids while  coating the pavement surface. The resulting smooth and even texture  makes the surface easier to maintain year-round. For example, snow is  easier to remove from a smooth surface, and sweeping is far more  effective on a smooth surface.

Sealcoating increases pavement flexibility

Sealcoat brings a dark black color to the  pavement. The blacker it is, the more heat a pavement draws from the  sun. And, the hotter it gets, the more pliable it becomes, which helps  it to withstand traffic without cracking.

Protects asphalt from pressure washing

Restaurant parking lots often extend to  areas near dumpsters, where food-processing machines are pressure  washed. Food waste near the dumpsters may also need to be washed away if  it can’t be swept away. Sealcoating protects asphalt cement from the  high-volume water pressure and detergents used in pressure washing.

Asphalt sealcoating is cost effective

The price of asphalt will always be  affected by crude oil prices, which fluctuate when supplies vary.  Sealcoating preserves asphalt for pennies per square foot.

Preparation and Application

Prior to pavement sealing, any structural failures or cracks on the  pavement must be repaired. All potholes must be removed and replaced,  cracks must be cleaned and filled, and oil spots cleaned or primed.

Once the pavement is ready, the application can proceed as outlined  in our service agreement.
