We are proud to be designated by GuardTop as a Preferred Applicator. We have determined that GuardTop is the best parking lot seal available. There are less expensive seals, but the old adage “you get what you pay for” applies.

“GuardTop is proud to be a Leed Certified U.S. Green Building Council Member.”

“GuardTop is free of carcinogenic materials and is nonflammable - made with the environment in mind. With pavement preservation as our goal, we use recycled materials there-by reducing the environmental impact and preserving asphalt surfaces for generations to come.”

Parking lot seal, while thinner and containing less aggregate than Slurry Seal, is another effective way to protect asphalt- and may be a better choice given the specifics of your project. We use GuardTop Seal coating products to help customers protect their asphalt surfaces from moisture penetration, heat , cold and even ultraviolet damage. GuardTop is a great choice for parking lots and a cost effective alternative to Slurry Seal.

There are a couple of different ways to apply GuardTop; spraying or hand application. Hand application by squeegee and horse hair broom leaves more material on the parking lot. This type of application takes a little longer and does cost a more.
Spraying uses less material and requires less man power. Normally the spraying leaves a more even look with less material. G. Scott Asphalt can do either application depending upon the desires of the customer.

A good maintenance program for asphalt should include a means to protect the asphalt in a durable and cost effective way. One of the questions that we often get is “Which seal is right for our particular project?”
The answer: This depends on many factors, but there are general rules of thumb.

Many government agencies, including the military, port districts and public utilities, have determined that Slurry Seal is the only seal material that meets the specific demands of their roadways and parking areas.

Slurry Seal is a blend of asphalt emulsion, 1/8" - 1/4" aggregate, water, and Portland cement. These materials are proportioned, mixed together in a truck-mounted machine and immediately spread on the asphalt surface at a thickness of 1/4" - 3/8". As with all seals, Slurry Seal has no structural strength and will not prevent asphalt from cracking or breaking from deteriorated sub- grade conditions or traffic that exceeds the structural integrity of the existing asphalt. However, Slurry Seal possesses effective crack-filling capabilities, covers rough and raveled surfaces, raises existing elevations a minimal amount, and provides a 3 to 5 year wearing surface. Property managers, HOAs and other private sector entities are also seeing the benefits of Slurry Seal. It is important for board members/owners to see Slurry Seal projects to determine if they approve of the surface texture. Parking lots with tight turning radius’ may not be the best application for Slurry Seal as the seal tends to flex and tear due to power steering.

SLURRY SEAL PROS:
Contains 1/8”- ¼” of aggregate which creates a durable barrier against asphalt surface wear. Lasts up to 5 years depending on traffic and weather conditions. Accepted by most government agencies as the de facto asphalt seal product.

SLURRY SEAL CONS:
The seal may tear due to power steering turns. The seal will give up some aggregate as it wears. Sweeping maybe needed.

Parking lot seal, while thinner and containing less aggregate than Slurry Seal, is another effective way to protect asphalt- and may be a better choice given the specifics of your project. We use GuardTop Seal coating products to help customers protect their asphalt surfaces from moisture penetration, heat , cold and even ultraviolet damage. GuardTop is a great choice for parking lots and a cost effective alternative to Slurry Seal.

PARKING LOT SEAL PROS:
Deep, long lasting color that is pleasing to the eye. Right around half the cost of Slurry Seal Lasts 2-3 years depending on traffic and weather conditions.

PARKING LOT SEAL CONS:
Reflective cracking- cracks under the seal will show through. Power steering turns wil scuff the seal Parking lot seal is thinner than Slurry Seal.

Parking lot seal spread on 140,000 S.F. of street surface, uses approximately 22,000 pounds of oil, silica sand, and water. Slurry Seal spread on this same area uses approximately 233,000 pounds of oil, rock, water, and Portland cement. Slurry Provides 10 times the material, with added durability, at only twice the cost.

Both seals depend upon some heat to dry. Cooler weather and shade covered asphalt areas slow drying times. Either seal can remain wet for several days keeping home owners/renters out of their garages and parking areas until the seal dries. Delaying seal work until warmer weather causes less inconvenience to home owners/renters.
