Introduction
The Masterson Sta-Wet Handy Palette is designed to keep acrylics and other water-based paints moist and workable for extended periods. Its airtight design, combined with a specialized sponge and permeable paper, provides a constant source of moisture to your paints, preventing them from drying out for days or even weeks. This manual provides instructions for optimal use and care.
Package Contents
- 1 x Masterson Sta-Wet Handy Palette Tray with Lid
- 5 x Sta-Wet Acrylic Paper Sheets (8.5in x 7in)
- 1 x Sta-Wet Cellulose Sponge
Setup for Water-Based Paints (Acrylics, Watercolors, Gouache)
- Prepare the Sponge: Thoroughly wet the cellulose sponge with cold water. Squeeze out excess water until the sponge is damp but not dripping. Place the moistened sponge flat inside the palette tray.
- Prepare the Paper: Take one sheet of Sta-Wet Acrylic Paper. Wet the paper with warm water (not hot) and gently lay it on top of the moistened sponge. Ensure the paper is fully saturated and smooth, with no air bubbles underneath.
- Apply Paints: Dispense your water-based paints directly onto the prepared paper surface. The paper will slowly absorb moisture from the sponge below, keeping your paints workable.
- Close the Lid: When not actively painting, snap the airtight lid onto the palette tray. This creates a humid environment that preserves your paints for days, or even weeks.

Operating Instructions
Using with Water-Based Paints:
- The permeable paper allows moisture from the sponge to slowly transfer to your paints, extending their open time.
- Mix paints directly on the paper as needed. The paper is strong and will not easily tear, allowing for palette knife use.
- When finished painting, simply close the airtight lid to preserve your paints.
Using with Oil Paints:
- For oil paints, remove the Sta-Wet Acrylic Paper and the cellulose sponge from the tray.
- Insert your preferred oil paint palette (e.g., New Wave Artist Palettes, white plastic, gray acrylic, or tempered glass) into the tray.
- The airtight container will help slow the drying time and reduce oxidation of oil paints. Note that specialized oil palette paper is not included.

Maintenance
- Sponge Care: Thoroughly wet the cellulose sponge with cold water. Squeeze out excess water until the sponge is damp but not dripping. If mold or mildew appears, clean the sponge with a mild soap solution and rinse thoroughly. Some users recommend using distilled water to minimize mold growth.
- Paper Care: The Sta-Wet Acrylic Paper is reusable. After use, you can rinse off remaining paint with water. While the paper may become stained, its functionality will not be affected. Both sides of the paper can be used. Replace paper sheets when they become too worn or torn.
- Palette Tray and Lid: Clean the plastic tray and lid with warm soapy water as needed. Ensure they are completely dry before reassembly.
- Storage: For prolonged storage, especially in humid conditions, some users store the closed palette in a refrigerator to further inhibit mold growth.

Troubleshooting
- Paints Drying Too Quickly: Ensure the sponge is adequately moist and the paper is fully saturated. The lid must be securely snapped shut to maintain an airtight seal. High room temperatures or very dry environments can accelerate drying; consider storing the palette in a cooler place or using a palette wetting spray.
- Mold/Mildew Growth: This can occur in humid environments. Regularly clean the sponge and tray. Using distilled water for wetting the sponge and paper can help reduce mold growth. Some users also refrigerate the palette when not in use.
- Paper Tearing: While the Sta-Wet paper is durable, excessive force with a palette knife can cause tearing. Use gentle pressure.
