Asphalt is a good building material for a driveway. It is hard enough to hold its shape even if it gets wet, yet flexible enough that it won't crack when subjected to stress. On the other hand, weather can have an adverse effect on an asphalt driveway. In order to make sure that your driveway remains in good shape, you have to take steps to protect it from the elements, and this is where sealcoating comes into play.
What Is a Sealcoat?
The impetus for a sealcoat is the need to improve on the weaknesses of a driveway while building upon its strengths. To accomplish this, engineers will typically use coal tar, which is a byproduct of burning coal to smelt iron. Painting this tar onto a driveway will provide it with protection against the elements.
What Does a Sealcoat Do for a Driveway?
The UV rays of the sun will bake the volatiles right out of your asphalt in your driveway. This will make you driveway brittle and prone to cracking. A sealcoat will seal the volatiles inside of your driveway so that your driveway remains flexible, and this is only the beginning.
Water that pools up on your driveway can get down into the cracks between the pebbles that make up the driveway. If this water then freezes, it will expand and create a wedge that will eventually tear apart your driveway. A sealcoat will create a waterproof coating that will prevent frost wedging.
Finally, petroleum products can dissolve asphalt tar, which will allow the pebbles in your driveway to separate. A sealcoat will prevent petroleum products from tearing apart your driveway.
How to Prepare Your Driveway for a Sealcoat
If you have any sort of damage to your driveway, your sealcoat will not be able to adhere like it should. Thus, if you have cracks, you need to remove any loose or organic materials from them and then fill them with a rubberized joint-sealing compound. If you have potholes, then you need to fill them with a patching compound.
If the work is too hard for you, you can hire paving professionals to do the work for you. In any case, you will need to take steps to protect your driveway from damage. After all, it will be cheaper to pay to repair and protect your driveway than to replace your driveway when it is damaged beyond repair.Share
