Crack and Pothole Repair
Crack repair/filling using commercial-grade rubberized asphalt crack sealer, designed to seal out water and ice, and dries in 2 hours--far better than hardware store-purchased, do-it-yourself liquid acrylic crack fillers. Pothole repair/refilling using asphalt patching. Asphalt Sealcoating
Sealing provides a layer of protection over the entire lot/driveway. You may have had the cracks and potholes repaired and sealed, but a sealcoat adheres to the entire pavement surface, preventing the rest of it from developing cracks. Coal tar asphalt sealers repel the water from the surface (it has a beading effect, much like Rain-X applied on a windshield). This prevents water from seeping into small fissures and causing damage. It creates a protective layer against traffic and weather, and is resistant to oil, gasoline, road salt and many other staining agents. And because the sealcoat is sprayed on, the process takes far less time than you would think, and you can walk on the surface in as little as 15 minutes (total drying time is between 3 to 4 hours, depending on weather conditions). Re-striping
Bob's been painting for over 35 years, and that includes painting stripes on parking lots. The same principles apply--choose the best materials (paint that won't wear or fade quickly), clean/prep the area to be painted (this includes removing dirt/debris, making sure the area is dry, and making sure that the parking lot is free of cracks and potholes). Also, sealcoating is strongly recommended, to provide a layer of protection, as well as a slate black finish that will really increase the visibility of the parking lot stripes (Bob has all the stencils necessary for painting numbers, lines, arrows, handicap signs, "No Parking" labels, etc.).
