Fluid-applied air and moisture barrier by Sto

Sto Guard is a seamless, fluid-applied air and moisture barrier that provides protection against air and moisture intrusion, and mold under cement stucco, if separated by a bond breaker with paper backed metal lath or other separation layer. It has also been proven to resist mold when tested in accordance with ASTM D3273. The barrier is vapor permeable and is applied beneath the stucco wall.
