Wet palette for miniature painting: what it does and what the best wet palette costs

How to choose

1. Decide between bought and home-made. A takeaway container, a sponge and baking parchment work. A bought palette adds a good seal, paper cut to size and a lid that survives being moved, which is what most people are actually paying for.
2. Check the lid seal, not the box. The feature that matters is whether paint survives overnight. A palette that seals will still have usable paint tomorrow; one that does not is just a wet surface.
3. Buy the right paper. Palette papers differ in how much water they pass. Too permeable and your paint floods; too little and the palette does nothing. Replacement paper is a running cost worth checking.
4. Match the size to your desk. Large palettes hold a full scheme and take up the space you paint in. Most painters find a small palette they can leave open beside the model is used far more than a big one.

What a wet palette actually changes

Acrylic paint dries by water leaving it, and on a dry palette that starts immediately. Within a few minutes the paint on the palette is thicker than the paint you mixed, so the coat you apply at the end of a session is not the coat you applied at the start. A wet palette feeds water up through the membrane continuously, holding the paint at the consistency you mixed it to for as long as you are working. The visible effects are better coverage, smoother coats, and blends that behave predictably because the two colours you are blending have not quietly changed while you were working.

Why it saves more paint than it seems

The paint left on a dry palette at the end of a session is wasted, and for painters who mix custom colours that waste includes the mix itself, which is far harder to replace than a pot colour. A sealed wet palette keeps a mix usable across sessions, which means a colour mixed once can finish a whole unit rather than being approximated again each evening. For anyone painting a force to a consistent scheme this is the real argument for the tool: not the paint saved by volume, but the consistency of a mix that survives from one sitting to the next.

Mould, flooding and the maintenance nobody mentions

A wet palette is a warm damp box, and left alone it will eventually grow mould. Changing the water, rinsing the sponge and replacing the paper keeps it clean, and many painters keep the sponge in the fridge between projects or add a small amount of a suitable additive. The other common complaint, paint flooding and running on the surface, is almost always too much water in the sponge rather than a fault in the palette: the sponge should be damp, not swimming, and the paper should be flat against it with no standing water on top.

Common questions

Does a wet palette really make a difference?

Yes, particularly for blending and for keeping a mixed colour consistent. It holds paint at the consistency you mixed it rather than letting it thicken over the session.

Can I make a wet palette at home?

Easily, with a sealable container, a sponge and baking parchment. What you give up is the seal quality, pre-cut paper and durability, which is what the shop-bought versions charge for.

How do I stop a wet palette going mouldy?

Change the water, rinse the sponge between projects and store it clean. Leaving a sealed damp palette full of paint for weeks is what grows mould.
