Specific sealer for concrete block paving with sand in the joints as it both seals the surface of the blocks and hardens the kiln dried sand in the joints at the same time.
Very popular treatment for concrete block pavers as it protects the surface from oil and water based staining and inhibits weeds from growing up through the joints.
Used in commercial and domestic driveways. Sand is consolidated but does not stick to the side of the blocks so it binds the sand together allowing it to be flexible which is necessary for this type of paving solution.
Where to Use
Used on exterior concrete block paving only.
