Clean the paved surface with a pH-neutral cleanser and a power washer to remove any accumulated dirt or debris. Use a concrete degreaser and scrub brush on pavers with signs of oil-based stains . Rinse the pavers off with the power washer then allow the surface to dry for 48 hours.
Check for any loose pavers or any joints between the pavers that require filling. Tamp down loose pavers with a tamper until the paver surface is level with surrounding pavers. Fill joints by spreading sand over the paved surface and then sweeping it into the joints between the pavers with a push broom. Remove any loose sand using a blower directed in back-and-forth motion, proceeding steadily from one end of the pavement to the other.
Fill a hand-pump sprayer with the sealer. Pump the handle of the sprayer a few times to compress the air inside.
Aim the pump nozzle directly at the paver surface from about 8 inches away. Trigger the sprayer and spray the glaze onto the pavers. Spray with a back-and-forth motion in overlapping rows for even coverage. Use a heavy coat, saturating the joints between the pavers, but do not allow the glaze to pool on the paver. Push any excess glaze into the sandy joints with a squeegee instead of allowing it to remain on the paver surface. Allow the glaze to dry for two hours, and then apply a second lighter layer to cover any sections missed by the first.
Wait two hours more before stepping onto the pavers and 72 hours before allowing vehicles to drive onto the pavers.
