A wet palette is the cheapest technique upgrade in miniature painting, and the Redgrass Everyday is the one that turned a DIY trick into a product people actually pay for. The pitch is simple: paint that stays wet and workable for days instead of skinning over in minutes. The catch every buyer eventually asks about is mold. We mapped the Redgrass against the wet-palette field on our bench rubric — seal, hydration, and how you keep it clean — to sort the real value from the marketing.
The one-line verdict
If you thin your paints, blend, or ever walk away mid-session, a wet palette pays for itself the first week, and the Redgrass Everyday is the low-friction way in: a proper airtight lid, hydration foam that holds water evenly, and a paper that does not let paint bleed through on the first stroke. At around $30 it costs more than a Tupperware-and-sponge setup — you are paying for the seal and the paper.
Mold is a habits problem, not a product flaw, and the fix is boring. More below.
How a wet palette works
The principle is capillary action. A water-charged foam or sponge sits under a semi-permeable membrane; you put paint on top of the membrane, and moisture wicks up from below just fast enough to keep the paint open without flooding it. The result is that your carefully thinned mix — the one that took three drops and a minute to get right — is still there and still usable hours or days later, instead of a dried crust you have to remix.
That single change fixes the most common beginner frustrations at once: paint drying on the palette mid-mini, wasted paint, inconsistent thinning between loads, and the impossibility of holding a custom mix across sessions. Pair it with a brush that carries a proper reservoir — our Winsor & Newton Series 7 review explains why a wet palette and a good round belong together — and smooth blends stop being a fight.
What Redgrass gets right
The Everyday is the mid-size tray in the range, above the compact Painter and below the Studio XL, and it sizes well for a normal bench. Three things justify the premium over a homemade version:
- A real seal. The lid closes airtight, so the palette stays hydrated between sessions and paint survives closed for days rather than drying out overnight.
- Engineered hydration foam. It holds and distributes water evenly, so you do not get a soaked patch in one corner and a dry one in the other — the failure mode of a kitchen sponge.
- Paper that resists bleed-through. The Redgrass hydration paper lets moisture up without letting your paint sink through on the first stroke, which is the annoyance that makes cheap parchment frustrating.
For speed painters the benefit compounds — a set like Army Painter Speedpaint 2.0, reviewed in our Speedpaint 2.0 review, or a full Vallejo Model Color 72 palette stays open long enough to work a whole squad from one loaded mix. Our best speed and contrast paints roundup covers which of those pair best.
The mold question, straight
Any wet palette can grow mold — it is a warm, damp, organic-friendly environment by design. The Redgrass foam and paper resist it better than an improvised sponge, but nothing is immune, and this is where the honest advice lives:
- Do not store it paint-loaded for weeks. Peel the paper and rinse the tray when you are done with a mix you no longer need.
- Refrigerate for long pauses. Cold dramatically slows mold; a sealed palette in the fridge holds paint for well over a week.
- Refresh the water and let the foam breathe occasionally rather than leaving it permanently saturated.
- Swap the paper when it discolors, and rinse the foam if it starts to smell.
Do that and mold is a non-issue. Ignore it, leave a loaded palette sealed on a warm shelf for a fortnight, and you will open a science experiment — which is a habits failure, not a defect.
The trade-offs
The obvious one is that you can approximate this for a few dollars: a food container, a kitchen sponge, and baking parchment is the classic DIY wet palette, and it works. What Redgrass sells is convenience and consistency — a lid that actually seals, foam that hydrates evenly, and paper cut to fit that does not bleed on contact. Whether that is worth roughly $30 depends on how much a leaking, unevenly-wet, fiddly homemade version would annoy you. For painters who value a bench that just works, it is an easy yes; for tinkerers on a tight budget, the DIY route is genuinely fine.
Consumables are the other cost: hydration paper runs out, and refills are an ongoing (small) expense. Budget for it the way you budget for paint.
The verdict
The Redgrass Everyday Wet Palette does exactly what it claims — keeps paint workable for days behind a seal that holds — and it does it with less fuss than anything you would rig up yourself. Mold is real but entirely preventable with a rinse, a paper swap, and the fridge for long pauses. If you thin and blend your paints, this is one of the highest-impact $30 purchases on the bench. If you paint straight from the pot and never walk away, you can skip it. For most painters chasing smoother results, it is the upgrade that makes every other technique easier.

Questions builders ask
What does a wet palette actually do?
It keeps your paint wet and usable for hours or days instead of minutes. A damp foam under a semi-permeable paper wicks moisture up to the paint, so a thinned mix stays workable across a session — or, sealed, across days. That means smoother blends, less wasted paint, consistent thinning, and the ability to hold a custom color mix instead of remixing it every time.
How do you stop a Redgrass wet palette from getting moldy?
Do not store it paint-loaded for weeks, refresh the water rather than leaving the foam permanently soaked, and refrigerate it for long pauses — cold slows mold dramatically. Swap the hydration paper when it discolors and rinse the foam if it smells. The Redgrass foam and paper resist mold better than a DIY sponge, but the real defense is simply not leaving a sealed, wet, loaded palette sitting warm for a fortnight.
Is the Redgrass wet palette worth it over a DIY sponge version?
For convenience, yes. A food container, sponge, and parchment works and costs a few dollars, but the Redgrass gives you an airtight lid that keeps paint alive for days, foam that hydrates evenly, and paper that does not bleed on the first stroke. You are paying around $30 for a bench tool that just works instead of one you have to fiddle with. Budget tinkerers can happily DIY; everyone else buys the convenience.
How long does paint stay wet on a Redgrass palette?
Open on the bench, thinned paint stays workable for many hours — long enough for a full painting session without remixing. Sealed with the lid, it holds for days, and refrigerated it can keep a mix usable for well over a week. Exact times depend on how thin your paint is and your room's humidity, but "days, not minutes" is the honest headline.
