How to Apply Asphalt Crack Filler 1

Asphalt driveways offer a highly durable solution to improving curb appeal and providing a smooth driving experience. However, over time, cracks can develop in the asphalt due to the changing weather and usage. This is where asphalt crack filler comes to rescue.

What is Asphalt Crack Filler?

Asphalt crack filler is a special product designed to fill and seal cracks in the asphalt surface, preventing water from seeping in and causing further damage. The filler is typically made of rubberized asphalt or tar-based material that can expand and contract with the changing temperatures. It comes in liquid form and can be applied using a caulk gun, squeegee, or brush.

Preparing the Surface

Before applying the asphalt crack filler, it is essential to prepare the surface properly. Start by cleaning the cracks and removing any debris such as weeds, dirt, and loose asphalt. For best results, use a high-pressure water hose to blast away the dirt from the cracks. Allow the cracks to dry completely before proceeding to the next step.

Applying the Crack Filler

Once the cracks are dry, it is time to fill them. First, cut the tip of the tube or bottle of filler to the desired size of the crack to ensure an even flow. It is vital to read the manufacturer’s instructions for preparing the filler before use.

If using a caulk gun, insert the tube into the gun, hold the tip of the gun at the opening of the crack, and slowly squeeze the trigger to apply the filler. Move the gun slowly along the length of the crack while maintaining an even flow.

If using a squeegee or brush, pour the filler into the crack, spreading it evenly using the tool of your choice. Always wear gloves, as filler material can be tough to clean from your hands.

Finishing up the Job

Once the crack filler is applied, it is important to smooth it out and ensure even coverage. Use a scraper or trowel to level the material or slightly overfill the crack to ensure that it is sealed adequately. Be sure to feather out the edges of the patch to ensure a smooth finish.

Allow the crack filler to dry for at least 24-48 hours before allowing vehicles or foot traffic. After that, keep an eye on the crackfill repair section and check for any defects or additional cracks that may develop over time. For more significant areas that need attention, it is best to seek professional help from an asphalt repair company.
