Gold Bond® Two-Way Hardwall Plaster is a basecoat gypsum neat plaster which requires the job site addition of an aggregate and water to produce working qualities. When properly proportioned with aggregate, Two-Way Hardwall Plaster forms a hard, durable base for the finish coats of another gypsum plaster. Complies with ASTM C28.

Use Two-Way Hardwall Plaster with sand or expanded lightweight aggregate conforming to ASTM C35. It is mechanically mixed at the jobsite. Apply it by hand or use it through pump/spray plastering machines.

Two-Way Hardwall Plaster consists of unaggregated gypsum plaster and contains no asbestos.
