What is the best way to protect my interlocking brick?
Protection is best achieved by sealing the interlock with a special clear sealer at an approximate cost of $1.00 per square foot. This includes a pressure wash of the bricks to remove any weed or grass growth, resanding between the bricks, and finally the application of the sealer. Added benefits is that it will help to inhibit further weed growth and will protect the porous bricks from staining. It also darkens the appearance of the bricks which is esthetically pleasing.
