Where can I buy 3-6 sheets of this stuff? Last made about 2-3 years ago.
I don't know if Masonite is still making that stuff but James Hardie makes a cement board siding with a stucco pattern. It is 5/16 inch thick and comes in 4x8 and 4x10 sheets. The Hardie siding is a lot more moisture resistant than the Masonite. You can order it through you local building supplier.
