Palette Sponge Refill Creative Tools — wet palette sponges, pack for maintaining moisture

Replacement sponge pads for a wet palette by Creative Tools designed to maintain a consistent moisture layer for acrylics and other water-based paints. These wet palette sponges provide an even, absorbent base that helps control humidity inside the palette and slows paint drying, supporting longer working times and smoother blending. Packaged as spare inserts, they are intended for regular maintenance of wet palette kits and for replacement when original pads become worn or contaminated.

Advantages

These foam inserts are made to fit standard wet palette layouts and offer uniform water distribution to keep the upper membrane evenly damp. The material is resilient and compressible, allowing the membrane to sit flat while providing sufficient water storage. By replacing worn sponges, users restore optimal moisture control, reduce the need for frequent rewetting, and extend the useful life of paints during painting sessions.

Suitable for

• Hobby painting with acrylics
• Model building and miniature painting
• Illustration and concept art requiring extended open time
• Classroom and workshop use where multiple sessions occur

Key specifications

• Material: absorbent foam suitable for water retention
• Form: flat rectangular sponge pads compatible with wet palette trays
• Function: maintains moisture for water-based paints and acrylics
• Durability: reusable until worn, tear-resistant under normal use
• Care: easy to rinse and dry between uses to avoid contamination

How to use

Remove the old sponge insert from the wet palette tray and place the replacement pad flat in the tray so it covers the full base. Moisten the foam evenly with clean water until fully saturated but not dripping. Lay the palette membrane or baking paper over the damp sponge and smooth it to remove air pockets. Add paints onto the membrane and adjust moisture by adding small amounts of water if needed during the session. After use, rinse the sponge, squeeze out excess water, and allow it to air dry to prevent mold or odor.

Usage recommendations

Rinse sponges after each painting session and replace them if they develop permanent stains, odors, or lose their ability to evenly hold water. Store spare sponge inserts in a cool, dry place and avoid folding or compressing them for extended periods to maintain shape and absorbency.
