OS-400 can also be used on double 5/8" drywall applications. The diamond-punched paper edging allows for easier feathering, faster drying, and the highest bonding strength. Also guarantees an even lay-down of the paper, providing maximum adhesion with no rippling or blistering. Apply with all-purpose joint-compound.
