Product Specification

Modern Masters® Venetian Plaster is a finishing technique using thin layers of plaster applied with a spatula or trowel and then burnished to create a smooth surface with the illusion of depth and texture. You can control the sheen level of the finish by simply sanding and burnishing until the desired sheen is obtained. The more you burnish, the more translucent the finish becomes, re-creating the translucency found in real marble. The finish becomes so smooth it even feels like real marble. By varying the color, application technique and the amount of burnishing, other finishes can be created including stone, worn leather and suede.

SURFACE PREPARATION

The surface should be free of imperfections, sealed with a primer-sealer and have a low sheen. Fill cracks and nail holes, then seal with a primer-sealer. (Note: Tint the primer-sealer to a color similar to the color chosen for the Venetian Plaster.)

APPLICATION

NOTE: Always test the product in a small, inconspicuous area before beginning a project. We recommend preparing a sample board prior to beginning a project to check color and technique. The paint should be mixed thoroughly before using.

Step 1 – Skim Coat: Apply a skim coat of Venetian Plaster with a Modern Masters Japanese Trowel at a low trowel angle (2 finger space) and scrape off excess at a high trowel angle (3 to 4 finger space). Let dry 1 hour.

Step 2 – Texture Coat: Apply a texture coat of Venetian Plaster with a low trowel angle and light pressure using a skip trowel technique. This technique will produce peaks that should be “knocked down” by smoothing lightly with a low
trowel angle. Let dry for 1-2 hours.

Step 3 – Skim Coat: Repeat the process done in step one and let dry for 1 hour. For suede and stone looks, burnishing/polishing is not needed.

BURNISH/POLISH: For a marble-like finish, sand the dry Venetian Plaster in a circular motion with 400 grit dry sandpaper (a palm sander can be used). For a higher sheen, dust off with a soft rag and sand with 600 grit dry sandpaper.
Dust off with a damp soft rag. To get a very high sheen, after sanding, burnish the surface by rubbing vigorously with your trowel or the flat side of a clean putty knife. This is not recommended for light colors.

TAPING: Use high quality, low-tack tape when taping over surfaces that have been previously painted. Therefore consider cutting along the tape edge with a razor blade to avoid delaminating the fresh paint from the substrate.
