Block Guard is a transparent, solvent-based acrylic coating developed to stabilise jointing sand and create a strong, protective seal across block paving and other mineral surfaces. It works by penetrating deeply into both the pavers and the jointing sand, then curing through solvent evaporation.
Ideal for use on block-paved driveways and paths, natural stone patios, and cement-based paving slabs, this resin-based sealer enhances surface durability while helping to keep joints firmly in place. Its long-lasting acrylic formulation also makes routine cleaning easier and more effective.
