Polyvinyl Acetate Emulsion

PVA, Vinyl Polymer Tempera - Supports and Grounds

1. Sand the Masonite in the usual way.

2. To size the panel, dilute the PVA using

1 volume PVA
2 volumes water

Apply a thin coat and allow it to dry. Then apply another coat of the size. Allow this to dry thoroughly [about 30 minutes]

3. Prepare the gesso by combining

1 volume PVA
2 1/2 volumes water
3 volumes dry pigment filler [70% whiting, 30% titanium dioxide]

Add the water to the PVA emulsion. Combine them with the filler to make a smooth mixture, free of lumps. The proportion of titanium to whiting may be increased to make the gesso whiter. More water may be added if a thinner gesso is desired.

4. Apply several coats of gesso to the panel, brushing each coat at right angles to the preceding one. No heating is necessary to keep the gesso liquid. Gently stir the gesso from time to time to prevent the pigment filler from settling to the bottom of the mixture. The gessoed panel can be given a thin wash of the dilute PVA sizing solution as an imprimatura.

5. If a textile surface is desired, raw linen can be mounted on an ungessoed Masonite panel.

a. Size the Masonite with the PVA emulsion, diluted with two parts of water.
b. Stretch the fabric over the panel while the size is wet.
c. Brush the sizing solution over the fabric and allow it to dry.
d. Gesso the surface as in steps 3 and 4.
