Applying sealant to your asphalt surface is an essential step in maintaining its durability and appearance. However, preparing the asphalt beforehand is crucial for achieving the best results. This guide provides you with the essential steps for preparing asphalt surfaces prior to applying sealants, ensuring maximum adhesion and longevity. Let’s dive into the important techniques that will help you achieve professional results.
Why is preparation important?
Proper preparation of the asphalt surface ensures that the sealant adheres effectively, allowing it to provide maximum protection against wear, tear, and environmental factors. Failing to prepare adequately can lead to premature peeling or cracking of the sealant, decreasing the lifespan of your asphalt.
Steps for preparing your asphalt surface
-
Clear the area:
- Remove any loose debris, like leaves and dirt.
- Pick up large items that could interfere with your work.
-
Inspect for damage:
- Look for cracks or holes.
- Identify any areas that may need repairs before sealing.
-
Repair cracks and holes:
- Use asphalt patching material for larger holes.
- For cracks, apply a suitable crack filler.
-
Clean the surface:
- Utilize a power washer or a broom to remove loose particles.
- Ensure that the surface is completely clean before proceeding.
-
Allow for curing:
- Make sure that your asphalt is fully cured.
- This usually takes about 30 days for new asphalt.
-
Check the weather:
- Only apply sealant on clear and dry days.
- Avoid rainy or extremely humid days that could harm adhesion.
