Sealcoating is one of the most effective and economical ways to prevent damage to an asphalt pavement as well as enhance its appearance. Sealcoating acts as a sunblock, helps prevent automotive fluids from deteriorating the pavement, and restores the color to faded asphalt pavements. Because it is such a useful product, some people assume that thicker is better when it comes to asphalt sealcoating. However, the reality is that sealcoating needs to be applied at the right thickness if the pavement is to be properly protected.
What Is the Problem With Applying Asphalt Sealcoating Too Thickly?
The liquid Waycross sealcoating contractors apply is about 70% water by volume. As this water evaporates, the particles in the sealcoating mix knit together to create a tough shell that adheres to the pavement. Evaporation must be steady, even, and predictable for the sealcoating to create the shell and adhere properly. If sealcoating is applied too thickly, the results will be similar to what happens when paint is applied too thickly. Both paint and sealcoating will experience delays in drying as well as potential peeling, blistering, or cracking. Just like paint, the key to a successful sealcoating application is to apply a thin coat, then apply an additional coat if more coverage is necessary. For most applications, two thin coats of sealcoating are sufficient to protect an asphalt pavement. However, high-traffic areas, including drop-off or drive-thru lanes, may require a third coat. In other words, multiple coats will increase the total thickness of the sealcoating, which will provide greater protection, but each coat must be thin enough to dry at the proper rate.
Does the Brand of Sealcoating Affect the Application Thickness?
Slight variations are possible because some manufacturers sell products that can vary in viscosity. However, no manufacturer produces a sealant that can be successfully applied as one thick coat. Instead, every manufacturer states that their products are to be applied in thin coats that are allowed to dry before subsequent coats are applied.
To Ensure They Do Not Apply Asphalt Sealcoating Too Thickly, Should Contractors Use Sprayers or Squeegees?
Just like any other tool, there is a time and a place to use a sprayer, and there is a time and a place to use a squeegee. It is very common for a Waycross sealcoating company to use both sprayers and squeegees on the same job.
- Experienced, skilled workers can apply a thin coat with a squeegee. The most common reasons for using a squeegee include getting into tight spaces, edging the perimeter of the pavement, or achieving maximum control near curbs or structures.
- Sprayers are faster than squeegees, so they are normally used when sealcoating parking lots and other large, open areas. Sprayers need to be properly maintained and operated by skilled, experienced workers to ensure a precise, even application.
- Regardless of the application method, the pavement must be dry and clean. Furthermore, cracks and other damage must be repaired. It may also be necessary to apply a primer to oil stains so that they do not prevent the sealant from adhering properly.
