Sealers Used for Sealcoating Asphalt Driveways

During winter, sealing in windows helps ensure that heat doesn’t escape. This method, however, requires a proper sealant to work. For instance, silicone caulk works well for glass and metal surfaces, yet does not adhere to wood surfaces. The same principle applies when sealcoating asphalt driveways, for which only certain types are recommended.

Coal Tar Sealers

These sealers consist of refined coal tar mixed in with several chemicals. The latter help make the surface resistant to the harmful effects of heat, snow, and rainwater. Aesthetically speaking, these sealers score high as they create surfaces with shiny or glossy finishes.

Asphalt Emulsion Sealers

There is no question that this type of sealer complements asphalt driveways rather well because they basically have the same composition. However, for this type of sealer to work, application must take place on days when temperatures are at least 50 degrees Fahrenheit.

Acrylic Sealers

,  are considered ideal for both indoor and outdoor applications. Acrylic holds up well to any element that can harm any surface, making acrylic-based sealers a smart choice for protecting asphalt driveways. In addition, these sealers come in a variety of colors that make for an attractive finish, from earth hues like terra cotta to light green.


A Close Look at Seal Coats for Asphalt Surfaces

In the art world, a seal coat is an important element applied by the artists to their paintings before hanging these on their walls or turning them over to art gallery owners for display. A seal coat basically protects the artworks and maintains its texture and color. The old paintings you see in museums are likely preserved with a seal coat.

In parking lot maintenance, a seal coat serves the same purpose as well. Applying a seal coat to the surfaces mean adding a layer of protection, thereby increasing the parking lot’s strength and resistance to elements like harmful UV rays, heavy rainfall, and oil or gas spills.

Seal coat for asphalt surfaces typically come in two forms, namely coal-tar emulsion-based products and asphalt emulsion-based products. Coal tar sealers contain refined coal tar with a mixture of several chemicals. This combination of ingredients is similar to the ones often used in flat roofs to offer protection from the elements.

Meanwhile, asphalt emulsion sealers are asphalt-based which consists of a soap-like emulsifying agents. Most of the time, special chemicals and pigments are added to this type of sealer for optimum strength and durability. One thing to keep in mind about asphalt emulsion sealants is that they should be applied to surfaces within temperatures of at least 50 degrees Fahrenheit, making the months of May through September ideal months for seal coating asphalt parking lots.

The Basics on Asphalt Seal Coating

During the recently-concluded winter, wise property owners almost certainly made sure to seal their doors and windows to prevent drafts from coming in. Sealing them in also prevented the heat produced by heating systems from escaping the property. Sealants in parking lots have a different function but they are just as essential.

Like windows, sealants in asphalt pavements are often needed to seal in cracks or gaps. However, even without obvious signs of cracks or gaps, seal coating is still necessary as it provides the asphalt pavement an additional layer of protection from factors like excessive heat or moisture and heavy traffic that typically lead to advanced deterioration or wear and tear.

Seal coating also helps asphalt pavement achieve a smooth texture that allows parking lot operators to easily have the structures cleaned and maintained since dirt and debris can easily be swept off them. Seal coating also prevents these surfaces from bearing the brunt of oil or gas spills. Penetration of these elements causes the asphalt to soften and break down.

Before sealant is applied to parking lot surfaces, the surfaces must be cleaned of any traces of dirt, oil, sand, or grease residues. Doing so will allow the sealant to adhere properly upon application. In cases of extremely rough surfaces, contractors can add clean silica sand to the sealants.
