Select a glossy solvent-based sealer, which is less translucent and allows for brighter color application.
Select an industrial powdered pigment in your color of choice and stir it into the sealant, using the metal stirrer. Add enough pigment to produce the hue you prefer.
Cover the areas around the driveway with tarps or plastic. This will prevent over-spray from damaging the lawn or other landscaping.
Apply the sealant using an airless paint sprayer. Fill the sprayer according to the manufacturer's directions for paint. Spray in a left to right motion, completely covering the drive area. Allow to dry.
Spray a second coat if needed, after the first coat dries. A second coat will darken the color.
