Question: What is sealcoating?

Answer: SealMaster® pavement sealers are designed to protect and beautify your asphalt driveway or parking lot. Sealcoating prevents oxidation of the asphaltic binder, prevents weather damage, reduces maintenance costs, and adds years of life to the pavement.

Question: When should an asphalt sealer be applied?

Answer: New asphalt should cure a minimum of 30 to 60 days. Once the asphalt is free from oils and sufficiently cured you can apply the sealer.

Question: At what temperatures should seal coat be applied?

Answer: You must have 50 degrees and rising for a 24 hour period.

Question: What other weather requirements are needed when sealcoating?

Answer: You should not apply sealcoating if rain is imminent within a 24 hour period.

Question: How long should we keep vehicles off the surface after sealing?

Answer: Please give the seal coat 24 hours after the final coat to cure prior to opening back up to traffic.

Question: How should the asphalt be prepared before sealcoating?

Answer: Surfaces must be clean and free from all loose dirt and material. Pavement surfaces should be repaired with a suitable hot or cold asphalt mix. Cracks should be filled with SealMaster® hot or cold applied crack fillers. Treat all gas, oil or grease spots with SealMaster® PetroSeal™ or PrepSeal™.

Question: How is asphalt sealer applied?

Answer: Pavement sealer can be applied by brush, squeegee, or specialized spray equipment. Equipment shall be capable of spraying sealer with sand added.

Question: What are the coverage rates for SealMaster® sealer?

Answer: Coverage rates will vary based on the product. Follow the specification sheets for application rates. Apply two coats of sealer. A third coat may be applied to high traffic areas such as entrances, exits and drive lanes.

Question: What are the benefits to using additives in sealer?

Answer: Additives can assist in speeding up the dry time for additional coats of sealer, as well has help with sand suspension and reduce power steering marks.

Question: Is sand required for application?

Answer: Yes, clean silica sand should be included in the mix design. Sand provides slip resistance, helps with drying, and adds to the durability of the sealcoating material.

Question: Are SealMaster® products safe for anyone to use?

Answer: SealMaster® offers water‐based asphaltic products and acrylic products that are environmentally and user‐friendly.

Asphalt pavement, to keep in simple terms, is primarily rock and/or stone and gravel, along with a binder. The rock, or aggregate, is held together with this binder also known as asphalt cement.

The binder is created from the distillation process of certain crude oils. Maintaining this binder is essential in prolonging the deterioration of asphalt surfaces. Rain, U.V. rays, and chemicals, as they are introduced into the asphalt, will degrade the binder and thus begin the degradation process of the asphalt. This will continue and create a surface that turns brittle. To reduce the effects of these elements, it is important to implement a maintenance program that utilizes sealcoating to extend the life of your parking lot or driveway.

Sealcoating will provide a layer of protection blocking out the elements: water, oils, and U.V. damage. In addition, when applied to manufacturers’ specifications, sealcoating provides a slip resistant surface with a deep black finish that beautifies the parking lot or driveway. SealCoats are typically bituminous based products or acrylics. The sealcoat is in a liquid formulation of one of the above emulsions, mixed with water, silica sand, polymer additives, and other proprietary fillers and solids. These products can be applied by brush, spray or squeegee. A regularly scheduled sealcoating program will more than double the life of the asphalt, saving you significant dollars down the line. Instead of having to pay thousands of dollars for new pavement, it is more cost effective to spend only pennies on the dollar per square foot to maintain.

When applying a sealcoating product, follow the important steps referenced below to get the most protection and optimum performance:

  1. A minimum of two coats should be applied.

• Temperatures must be a minimum of 50 degrees and rising for a period of not less than 24 hours. Do not apply when temperatures are forecasted to get below the 50 degree mark.

• Do not apply if rain is imminent within the same 24 hour period.

• Once finished with the application of sealcoat, allow to cure 24 hours before allowing vehicle traffic back on the surface.

To summarize, sealcoating every two to three years will certainly extend the life of your asphalt pavement for minimal cost. When applied appropriately and at the right time, sealcoating prevents oxidation, sealcoating stops weather damage, and sealcoating beautifies pavement.
