| HD SEALER is an extra heavy-duty, high solids spirit/solvent based sealer developed for tradesmen (reduced labour cost as less sealer required) to protect very porous surfaces including porous slate, concrete, sandstone, most pavers and other masonry surfaces. Provides a high gloss, very durable coating, imparts a wet look and is suitable for internal and external use. It is not suitable for dense surfaces such as Terracotta or Porcelain. |
