Applications
Applications: This interior finish is intended for hand application over veneer or conventional sanded plaster basecoats, as well as directly to gypsum base as a one-coat system. Machine application is not recommended. When applied over veneer or conventional sanded plaster basecoat, the basecoat should be rough and open and allowed to set and only partially dry to provide suitable suction for the finish. Protect all finish materials and finish surfaces from contact with DIAMOND Veneer Finish – Sanded including glass, ceramic materials, metal and wood. Apply wood, plastic or other exposed trim after finish application. Apply a thin, tight scratch coat of finish over entire working area. Immediately double-back with material from same batch to nominal thickness 1/16 to 3/32. Begin troweling or texturing as soon as the material has become sufficiently firm. Smooth and level the surface with the trowel held flat; use water sparingly to lubricate
Texturing: A variety of textures from sand float to heavy Spanish can be achieved by using float or sponges. The application is the same, except that once the surface has been leveled and sufficient take-up has occurred, begin floating the material with trowel, float, sponge or by other accepted local techniques. DIAMOND Veneer Finish—Sanded also may be skip-troweled. When applying in this manner, eliminate final troweling. When the surface has become sufficiently firm, texture with material from the same batch prior to set
Decorating: Paint with acrylic or other high-grade latex breather-type paint the day following application, if the plaster is completely dry
Limitations
Limitations: 1. Not recommended where contact with water or excessive moisture may be encountered. 2. Not recommended for use over Portland cement basecoat or directly to masonry surfaces. Use IMPERIAL Veneer Basecoat or DIAMOND Veneer Basecoat applied directly to concrete block, or over a bonding agent on poured concrete, prior to application of DIAMOND Veneer Finish-Sanded as the finish coat. 3. Machine application is not recommended. 4. For recommendations over monolithic concrete, see USG literature PM6.
