You decided to seal your driveway. That’s a great idea and the perfect way to ensure the long life of your driveway. Before you seal your driveway you need to fill in the cracks. This will ensure that your driveway is fully protected and the sealant works properly. Here’s how to fill in the cracks.
- Clean your driveway
The first thing you want to do is clean your driveway. This will help to remove any debris that may be stuck in the cracks.
- Small cracks
If the cracks are between 1/8 to 1/2 of an inch it’s best to use rubberized asphalt-emulsion crack filler. Do your best to keep it in the crack because it can stain other areas. Use a caulking gun to apply the filler as this is the easiest and most accurate way to do it. If one is not available simply poor the material into the crack. Smooth out the material at the surface with a putty knife or trowel. You can also use rubber gloves and your thumb if a trowel or putty knife isn’t available.
- Larger cracks
If you have a big crack that’s more than two inches it’s best to fill it to two inches with crushed, and angular gravel. Make sure you avoid using larger gravel or pea gravel because it will shift and doesn’t give you a good base. Then you need to use a wooden post or a steel tamper to compact the gravel. Once that is finished fill the crack using a cold process asphalt repair compound. Again use a tamper or wooden posts to compact the material. You may need to repeat the process to create a level driveway.
Make sure you do this on all the cracks in your driveway. Once you finished filling all the cracks you’re going to have to wait. The material will dry on the surface in about a day, but the rest of it could take as many as a few weeks to drive. You need to wait for all of the material to dry before sealing your driveway. If you don’t the material won’t dry properly and it won’t harden like it’s supposed to. Keep this in mind when you’re planning on sealing your driveway so that you give yourself an ample amount of time to fill in the cracks and level out your driveway.
