We use a top of the line water-based asphalt sealer. This product is non-toxic, Eco-friendly and it protects your asphalt for years. It is designed to protect your asphalt from harsh weather and vehicle liquids such as gasoline, coolant and motor oils. This means it is safe for yourself, your children and even your pets. Not only is it a safe and odor free product but it also leaves a beautiful and natural matte black finish to the asphalt. The dry time is very quick. After the work is done, you only need to wait 4 hours to drive on the asphalt! Needless to say, the product we use is the best on the market and it is good for residential use as well as commercial.
