Asphalt is made up of three major components, gravel, tar, and a variety of different aggregates. On average a newly paved residential driveway will last 15-20 years. The only way to extend a driveway's life and prevent damages is to seal it with the RIGHT Sealer. Sealing your a driveway or parking lot with a Tar sealer on a bi-annual basis can double the lifespan of your asphalt.
Tar is one of the original components in asphalt, for this reason, we only use 100% tar based sealer for all our maintenance projects from driveways, pathways and parking lots. A matte black finish provides a sharp consistent look for your property, helping your home or business stand out. Within the first year of new asphalt being paved the original component of tar (natural black component in asphalt) fully leaves the asphalt due to oxidation. Without Tar asphalt becomes grey and brittle losing its elasticity allowing moisture to soak in. Moisture causes the Asphalt to expand during winter months due to freezing temperatures. Expansion to the asphalt is the leading cause for a number of damages ranging from cracking, sinking, heaving and other erosion's. Tar and water do not mix naturally, by replenishing your asphalt with tar, water is unable to penetrate the asphalt surface instead moisture is repelled. Beading off to designated drainage areas (end of a driveway, sewers, catch basins, etc.), protecting the asphalt from damages greatly prolonging the life of your pavement. Tar-based sealer is able to cure into the pores of asphalt similar to the way a stain cures into wood. Because of this, it is not necessary to reseal every year. We recommend that asphalt is sealed every two years extending the life of your Asphalt surface while beautifying and adding curb appeal to your property
With countless "driveway sealing companies" in the market place it is difficult to distinguish between Contractors are honest and will provide you with a good product & quality service and fly by night "contractors" who will ruin your asphalt by using a cutback sealer. The " contractors" using cutback sealer are looking to make a quick buck off and go on to the next house scamming homeowners in the process. Some "contractors" cut their material with used motor oil, gasoline, diesel fuel, and even paint thinners such as varsol. extremely negative effect on on your pavement.
GASOLINE / DIESEL FUEL: When you get your driveway sealed with a gasoline or diesel fuel cut product you can expect to see discolouration, uneven coverage throughout the Asphalt area sealed, in many cases when the sun reflects after rainfall you will see a rainbow pattern (similar to when gas is spilled in water). Just like used motor oil, gas and diesel will eat away at your Asphalt causing pitting and eventually pot holes.
USED MOTOR OIL: When you get your driveway/parking lot sealed with a used motor oil cut product you can expect to see slight brown discoulored areas throughout. Ever heard or seen driveways that leave footprints, tire marks and gets tracked into the house, not to mention gets on the kids hands and feet? all indications that your driveway or parking lot has been sealed with a used motor oil cut sealer. Sealers cut with used motor oil will eat away at your asphalt causing pitting and eventually pot holes (acting like a large oil stain) killer your asphalt prematurely.
VARSOL: Varsol is a highly concentrated paint thinner commonly used to clean tar and asphalt equipment. Making this an easy product for flyer by night contractors way to use to cut their material. By far the most DANGEROUS thing to put on your driveway or parking lot. you will know when a sealer has been cut with Varsol when the asphalt surface sealed has an extremely high gloss shine that does not go away or dull down with time. Asphalt surfaces sealed with varsol cut sealers are extremely slippery when wet. This is a huge hazard for family, friends and even the pizza boy slipping on the driveway, leaving you liable!
Acrylic or Coal tar (water based sealers) are commonly found in your local hardware store. These sealer are usually applied with a squeegee or rolled on with paint rollers (can also be sprayed). Acrylic and Coal tar (water based sealers) are commonly used by home owners trying to tackle the project themselves or many driveway sealing contractors. What many property owners are unaware of is that asphalt is porous and needs to "breathe" to allow some of the water accumulated to evaporate. Acrylic and coal Tar water based sealers are simply a thick paint that adheres to the top of an asphalt surface. By applying this sealer to a n asphalt surface you are capping the asphalt not allowing it to "breathe", retaining more water under the surface, pushing up in winter due to freezing temperatures causing more damage. Another negative outcome to using an acrylic/water based sealer is due to its paint like Properties like most paint products these sealers crack and chip under hot and cold weather. This causes unnatural surface cracking to form, which eventually worsens into spider web cracking leaving your driveway/parking lot a checker board of lose Asphalt. In addition coal Tar sealers are known to be extremely carcinogenic and have been banned in some parts of Canada and the US
