A water-based, non-sacrificial surface treatment for concrete and masonry that creates a hydrophobic and oleophobic layer to protect against graffiti.
Surfaceshield HD (PC952) is a water-based, low VOC, and low odor surface treatment designed to protect porous masonry surfaces such as concrete, brick, and natural stone from graffiti. It functions as a non-film-forming barrier that penetrates the substrate to create a hydrophobic and oleophobic layer, allowing for the repeated removal of graffiti using specific agents and hot water pressure washing.
