A 1m x 50m heavy-duty floor card is a breathable, thick paperboard roll designed to safeguard sensitive flooring—such as hardwood, tile, laminate, and stone—during construction, painting, and general maintenance work. Its permeable construction allows newly installed floors to continue curing and breathing while shielding them against impacts, scratches, grit, and light liquid spills. Supplied in a convenient 1-meter width by 50-meter length, it rolls out flat for rapid installation and can be taped together at the seams for comprehensive floor protection across walkways and rooms.
