Seal-coating is an effective and efficient way of renewing and protecting your asphalt surface from any harmful elements. Asphalt should be seal-coated every 2-5 years depending on the weather conditions and any other damaging components that will deteriorate the asphalt.Keeping your asphalt seal-coated helps asphalt resist gas and oil spills which quickly destroys asphalt if not taken care of. Here are four benefits to seal-coating:1)Seal-coat slows the oxidation and water penetration. By doing this, it is preventing unnecessary cracks from expanding and turning into potholes. Potholes are much more costly to repair and liability issues can occur.2)Seal-coat resists ultraviolet rays. Keep in mind, though, that seal-coat does not repair any damage that has already occurred to the asphalt; it just prevents the ultraviolet rays from further damaging the asphalt.3)Beautification of your asphalt. Fresh seal-coat brings a dark black color to the asphalt which presents the asphalt as being new-like. A freshly sealed asphalt creates a positive, clean, rich look to the company or residential complex.4)Cost-Effective. Seal-coating is cost-effective in the long haul. It is less expensive to seal-coat a parking lot every few years than to overlay or reconstruct a new asphalt parking lot. Seal-coat preserves the asphalt. Keep in mind that asphalt will always be affected by crude oil prices.Thank you for your business,D & H Asphalt, LLC
