Grade HF Hard Finish (GAF)

Grade HF Hard Finish was a finishing cement.¹ A 1990 EPA notice that published what GAF reported describes it as "a hard finish cement designed to be used as a final protective coating over other coats of cement," with "a smooth, glossy, hard finish," and gives it a temperature limit of 1,500 °F.¹

GAF's 1989 filing with the U.S. Environmental Protection Agency under the Asbestos Information Act, made for itself and The Ruberoid Co., gives the same limit, 1500 degrees F, and calls it a prepared cement manufactured by Ruberoid.² The filing says its formula is known only for 1938 and 1945.²
