Trade Kraft (sometimes referred to as Brown Rosin) is also used in a similar fashion to Red Rosin. Trade Kraft is a heavier basis weight sheet, but does not contain the strong sizing agent that Red Rosin does. The fiber used to make Trade Kraft is stronger than the fiber in Red Rosin. Hence, Trade Kraft is an excellent sheet for protecting finished floors from high traffic environments while other work is underway. Trade Kraft Rosin is sold in 36 inch wide rolls containing 432 or 500 square feet.
