1. Evaluate the Condition of the Asphalt:
Before starting any sealcoating project, it is essential to assess the condition of the asphalt. Look for any cracks, potholes, or other forms of damage that may require repair before sealcoating. Identifying these issues early on will help ensure a smooth and durable sealcoating application.
2. Clean the Surface:
Proper cleaning is crucial to remove dirt, debris, oil, and other contaminants from the asphalt surface. Thoroughly sweep the entire area using a broom or power blower to remove loose dirt and debris. Pay close attention to corners, edges, and any cracks where debris may accumulate.
Next, use a pressure washer or a hose with a high-pressure nozzle to remove stubborn dirt, oil stains, and other contaminants. Make sure to clean the entire surface, including cracks and joints, to ensure proper adhesion of the sealcoat.
3. Treat Oil and Grease Stains:
Oil and grease stains can penetrate the asphalt surface and affect the adhesion of the sealcoat. To remove these stains, use a degreaser or a commercial asphalt cleaner. Apply the cleaner directly to the stain and scrub it using a stiff brush or broom. Rinse the area thoroughly with water and allow it to dry completely before proceeding.
4. Repair Cracks and Potholes:
Cracks and potholes should be repaired before sealcoating to prevent further damage and ensure a smooth, even surface. There are various methods for crack and pothole repair, including crack fillers, patching compounds, and asphalt repair products.
For smaller cracks, use a crack filler or asphalt patching compound. Clean the crack or pothole thoroughly, removing any loose debris and vegetation. Apply the filler or patching compound according to the manufacturer’s instructions and level it off with a trowel or putty knife. Allow the repair material to cure completely before proceeding.
For larger cracks or potholes, it may be necessary to hire a professional asphalt contractor to perform the repairs. They will have the equipment and expertise to ensure a proper and lasting repair.
5. Trim Vegetation:
If there is vegetation growing in or around the asphalt surface, trim it back to prevent interference with the sealcoating process. Cut back any overhanging tree branches, shrubs, or grass that may obstruct the application of the sealcoat.
6. Fill Low Areas:
Low areas or depressions in the asphalt surface can collect water and affect the performance of the sealcoat. Fill any low areas with an asphalt patching compound to create a smooth and level surface. Follow the manufacturer’s instructions for application and curing times.
7. Apply Primer (if necessary):
In some cases, a primer may be required before applying the sealcoat. A primer helps improve adhesion and enhances the durability of the sealcoating. Check with the sealcoat manufacturer or a professional asphalt contractor to determine if a primer is necessary for your specific project.
If a primer is required, apply it according to the manufacturer’s instructions. Use a brush or roller to evenly distribute the primer over the entire surface. Allow the primer to dry completely before applying the sealcoat.
8. Protect Adjacent Surfaces:
Before applying the sealcoat, protect adjacent surfaces such as curbs, sidewalks, and buildings from overspray or accidental contact. Use plastic sheeting or similar material to cover these surfaces and prevent any damage or staining.
9. Check Weather Conditions:
Weather conditions play a crucial role in the success of the sealcoating application. Ideally, the temperature should be above 50°F (10°C) and the relative humidity should be below 85F.
