Step-by-Step Guide to Seal Cracks
Step 1: Clean the Cracks
To begin with, it is important to clear the affected area from dirt, debris, and any loose concrete. You should use a wire brush to clean the inside of the cracks as thoroughly as possible. This has the effect of guaranteeing that the sealant bonds well to the surface it has been applied on. When brushing is done, use a shop vacuum or a broom to sweep off the loosened debris. The cleaning process is very important and therefore should not be left out.
Step 2: Rinse the Area
Then, it is advisable to wash the cracks with water to wash off the dust that might still remain. The edges must be wiped with a damp sponge or rag. It is also important that the area be left to dry before applying the sealant. Make sure that there is no moisture to interfere with the bonding process since it is a major no-no for bonding to occur on a wet surface.
Step 3: Choose the Right Filler
Choose a crack filler or sealant that is right for your driveway. For small cracks, it is advisable to use a liquid crack filler. For the wider cracks, apply polyurethane sealant or any patching compound to the crack. Look at the label of the product to be sure that it is safe to be used outdoors.
Step 4: Apply the Filler
If you’re using a tube of sealant, cut its end and place it in a caulking gun. Pour the filler directly into the crack and ensure that it occupies the entire space of the crack. For wider cracks, there is a possibility that you will have to use a putty knife for you to apply the material uniformly. Take time to fill them in so that they do not get too full and cause a problem.
Step 5: Smooth the Surface
After that apply the putty knife or the gloved hand to scrape the surface of the filler and give a smooth surface. This step makes sure that the sealant is flat with the floor of the driveway and also means that no water is likely to accumulate on top of the sealant. Trim any unwanted filler material to give a smooth surface to the structure.
Step 6: Allow It to Cure
Some of the sealants require time to cure before they perform their intended function. It is also important to adhere to the manufacturer’s recommended drying time. In addition to this, one should not drive or walk over the repaired area until it has been cured. Curing takes 24 to 48 hours depending on the type of product and prevailing weather conditions.
Tips for Success
Work in Dry Weather: Fill the cracks on a day that is dry and there is no rain expected the following days.
Use High-Quality Products: Choose a good quality crack filler to get long lasting results.
