Once the desired surface has been left to dry and The Sealing Company is confident that the excess dirt has been removed, we will then start applying the first coat of paver sealer. The brick sealer is applied using a specially designed air spray gun to guard against streak marks and product pooling. Once the first brick sealer coat has been left to air-dry [approximately 45 minutes] The Sealing Company can then start applying the second paver sealer coat.
