Wet Palette Problems, Fixed
Almost every complaint about wet palettes is one of five faults, and four of them are the water level.
The short answer
A wet palette should be damp, not wet: saturate the foam or sponge until it holds no more, then pour off every drop of standing water before laying the membrane. If paint thins by itself on the surface, there is too much water underneath. If paint beads up instead of spreading, the membrane is too dry or the wrong paper.

How wet should a wet palette be?
Damp. Specifically: the foam or sponge saturated to the point where it absorbs nothing more, and then every drop of free water tipped out before the membrane goes on. If you can hear water move when you tilt the palette, there is too much in it.
The mechanism is simple. The membrane is semi-permeable. Water migrates up through it slowly, which is what keeps your paint workable. If there is standing water underneath, water migrates up fast, and your carefully mixed mid-tone turns into a glaze in about ten minutes. That is the single most common wet palette complaint and it is a water-level problem every time.
Fault 1: paint thins itself and goes transparent
Too much water. Lift the membrane, tip the palette over the sink, press the foam, pour off whatever comes out, and relay the membrane. The mix on it is gone — do not try to save a flooded mix by adding pigment, because the ratio is already wrong.
A second cause, less obvious: a membrane that is too thin or too permeable for the paint. Baking parchment brands vary wildly in how fast they wick. If you are using kitchen parchment rather than purpose-made hydration paper, test a new brand with a single drop before trusting a session to it.
Fault 2: paint beads up and will not spread
The opposite problem, and it has two causes.
The membrane is too dry. Brush a little clean water across the top and wipe the excess. Hydration paper needs its surface wetted when it is first laid down; it does not pull enough water through to wet itself in the first few minutes.
The paper is coated or siliconized. Greaseproof paper, silicone baking paper and the shiny side of some parchments repel water deliberately. Paint will bead on them forever. Use the matte side, or use the manufacturer’s hydration paper, which is engineered for this and costs very little per sheet.
Fault 3: mold
Dark spots or a fuzzy bloom on the foam or at the edges of the membrane. Warmth, standing water and organic residue from paint binders are all it needs, and a sealed lid makes the conditions better rather than worse.
The fix, in order:
- Throw the membrane away. It is a consumable and it is the cheapest part.
- Wash the foam in warm soapy water, rinse it until it runs clear, and squeeze it dry. Replace it if the staining will not shift.
- Wash the tray and lid, which is where the spores hide.
- Change the water every few days, not every few weeks, and store the sealed palette somewhere cool rather than on a sunny windowsill.
Some painters add a drop of flow improver or a tiny amount of isopropyl alcohol to the water to slow growth. It works and it slightly changes how the paint behaves, so treat it as a trade rather than a free fix. General guidance on mold and moisture control applies here exactly as it does in a kitchen: remove the moisture and the food source.
Fault 4: it dries out overnight
Either the lid does not seal, or the palette is somewhere warm. A snap-lid palette is not water-tight — it holds a mix overnight and not much more. A water-tight palette holds one for days.
If you need multi-day mixes and the palette is a snap-lid, a freezer bag over the whole closed palette buys you most of the difference for nothing. The comparison of the two seal types is in Redgrass vs The Army Painter.
Fault 5: one mix skins while the rest stay wet
An air bubble under the membrane. The paper is not in contact with the damp foam at that spot, so no water reaches the paint above it.
Lay the membrane from the center outwards and press the air out as you go. If a bubble appears mid-session, lift that corner and resettle it. This is also why a palette that has been carried in a bag often behaves oddly when you open it — the membrane has lifted.
When the palette is not the problem
If paint is drying on your brush rather than on the palette, that is tip-dry and a flow improver fixes it, not a different palette. If the paint goes on streaky from a perfectly good mix, that is thinning ratio or brush loading — see how to thin miniature paint and how to load a brush.

The picks in full
Redgrass Games Everlasting Wet Palette Painter Lite
A sealed, mold-resistant wet palette small enough to live on a crowded desk. It keeps thinned paint usable for days instead of minutes.
What it gets right
- Paint stays workable for days with the lid on, which is the entire point of a wet palette
- Small footprint — it fits beside a model rather than replacing your desk
- Membranes and foam are sold as refills, so the palette itself is a one-time buy
Who it is wrong for
- Too small for batch-painting a whole regiment's worth of colors at once
- Refill membranes are a recurring cost you should price in
- Still molds if you leave paint and water in it for two weeks — nothing fixes neglect

Redgrass Games Everlasting Wet Palette Studio XL v2
The same sealed system at roughly twice the area. The right palette when you are painting ten models at once and need every color out at the same time.
What it gets right
- Room for a full army's palette plus mixing space in one lid
- The v2 seal genuinely holds — paint survives a week between sessions
- Large enough to wet-blend on, not just to thin on
Who it is wrong for
- Takes up most of a small desk; measure before buying
- More membrane area means more membrane cost per refill
- Overkill, and a waste of money, if you paint one model at a time

The Army Painter Wet Palette (Wargamers Edition)
A big working area for noticeably less money. The lid does not seal as hard, so paint lasts hours rather than days.
What it gets right
- Large surface at a fraction of the Studio XL price
- Comes with enough membranes to last a long while
- Does the core job — thinned paint stops skinning over mid-model
Who it is wrong for
- The lid does not truly seal, so paint dries out overnight rather than keeping for days
- Membrane sheets curl and shift more than Redgrass's
- Plastic feels cheaper, and the hinge is the first thing to go
