Sealing an Asphalt Driveway: Tips and Mistakes to Avoid
There are many advantages of sealing an asphalt driveway. Potholes can be formed when water seeps into the cracks and settles down the base, compromising the strength of the driveway’s base in the process. Cracks that were filled with water can also result to damage from freezing. Meanwhile in warmer climates, grass may grow up in the cracks from an unsealed asphalt driveway.
Common Mistakes to Avoid
One of the more common mistakes committed in sealing asphalt driveway is putting thick layers of asphalt driveway sealer, believing that it would give more protection on the surface. However, a thin layer should be enough to do the trick. Always follow the instructions of the asphalt driveway sealer manufacturer.
Likewise, an asphalt driveway sealer must be used a maximum of 6 months after its first installation. It should then be utilized at least once in 1 to 3 years. Sealing asphalt driveways once a year may be done in places where winter can be long and harsh; however, this could result to a very slick surface.
When preparing for asphalt sealing of the driveway, make sure that the weather is cooperative: the ground temperature should be around 45 degrees F. Likewise, dry weather should be expected at least in the next three days.
The Use of Appropriate Protective Gear
One should also prepare for sealing asphalt driveways by having appropriate wear as gloves. Asphalt driveway sealers are chemicals that should not be in contact with the skin. Inhaling the scent of asphalt driveway sealers is also a health hazard.
In preparing to seal an asphalt driveway, be sure to remove first all grass that overhangs the edges of the driveway surface. Stains from oil and gas should also be removed using a special detergent found in most auto supply shops. Clean the surface with a broom. Fill in cracks and depressions with patching compounds found in most home improvement shops.
Removing Dirt and Stains First
Dirt and stains should be first removed before sealing an asphalt driveway. Using the hose, remove dirt and stains missed in the cleaning process; an optional method is to clean the surface with a pressure washer since it makes the task easier and more effective. Afterward, let the surface dry.
Turn the asphalt driveway sealer upside down first to pre-mix its contents. Continue stirring its contents periodically after opening the tub; this will result to the asphalt driveway sealer becoming well mixed.
Seal One Corner at a Time
The most effective way in working on a driveway is to pour the asphalt driveway sealer in one corner. Most experienced workers go about by working on a smaller section one at a time rather than working on a long strip. Make sure to apply the asphalt driveway sealer thinly. Use a long handed brash to overlap coats on the surface.
The surface should be left to dry for at least 24 hours. During this time, the surface should not be parked with anything, especially with an automobile. Place a barrel or warning at the entrance of the yard to prevent vehicles from accessing the area. Stringing a yellow tape can also warn anyone on getting access to the driveway surface.
