Common Mistakes to Avoid When Applying Asphalt Crack Filler

Common Mistakes to Avoid When Applying Asphalt Crack Filler 1

Choosing the Wrong Type of Crack Filler

There are different types of crack fillers available in the market, and each one has its unique qualities. Choosing the wrong type of filler can lead to failure and ineffective repair. It’s important to understand the type of asphalt and its condition before selecting a crack filler. For instance, hot pour fillers are more effective for larger cracks, while cold pour fillers are ideal for small cracks. Additionally, some fillers are designed for specific environments, such as high-traffic areas or climates with extreme weather conditions.

Not Preparing the Surface Before Application

Preparation is a crucial step in ensuring the longevity of the asphalt repair. Neglecting to clean the surface and removing loose debris can result in poor adhesion and ineffective repair. Before applying the crack filler, clean the surface area of dirt, debris, and vegetation. Use a wire brush to remove loose debris and to ensure the crack is free from dust and other materials. Applying a primer can also improve adhesion, especially on surfaces that are poorly maintained.

Using Too Little or Too Much Filler

Improper application of the filler can decrease its effectiveness and result in a short-lived repair. Applying too little filler will result in a shallow repair that’s likely to sink with time, while using too much filler can cause shrinkage and cracking. A good rule of thumb is to fill the crack slightly above the surface of the asphalt, then use a trowel to level it. This ensures that the filler is compact and has enough elasticity to withstand the temperature changes and traffic load on the road.

Not Letting the Filler Dry Enough

After applying the filler, it’s important to give it enough time to dry before opening the area to traffic. The dry time depends on the type of filler used, temperature, humidity, and the size of the repair. Hot pour fillers typically dry faster than cold pour fillers and can be ready for traffic within hours. Cold pour fillers, however, may take up to a week to dry fully. Failing to give the filler enough time to dry can result in premature failure and reduced lifespan of the repairs.

Applying Filler on Wet Surfaces

Moisture and crack fillers don’t mix. Applying filler on a moisture-laden surface can result in poor adhesion and ineffective repairs. Before filling the crack, make sure the surface is dry, and there’s no rain forecasted for at least 24 hours. Using a hairdryer or a heat gun can accelerate the drying process and ensure the surface is dry and ready for the application of the filler.

Properly filling cracks in asphalt surfaces is a cost-effective approach to prolong the lifespan of the pavement and prevent minor issues from becoming major problems. Avoiding these common mistakes can make your repair job more effective and prolong its lifespan. Follow these guidelines and ensure to use high-quality products to achieve the best possible results.
