Sealing

Acrylic or polyurethane sealant can be applied to block-paved and resin bonded drives to provide protection from weathering, discolouration and weed growth. The sealant makes the sand between the joints in block-paving set hard. Acrylic sealant can be applied using a sprayer, polyurethane is applied with a roller. Edges are taped to protect areas from spread of sealant.
