DIY Wet Palette

In these harsh economic and meteorological times (yes, it’s STILL hot!) not everyone can afford stuff like this:

To help preserve paints in the heat, and also because mixing that one colour again was a once in a million thing and it’s a shame to have it dry up … let’s have a look at a cheaper DIY solution!

Usually, the palette used is unimportant; a clean piece of plastic will do. Old CDs are a prime candidate in the Mancave for being turned into palettes, “Take THAT, Mariah Carey’s Greatest Hits! Whaaapaa! There’s some Snot Green for ya!!” and so on. The normal palette allows me to mix colours and thin them with my thinning agent of choice. However, over time, the water in water-based paints will evaporate and the paint will dry out rendering it useless! Even under optimal conditions, the drying out of the paint is inevitable, more or less in the extremes of summer heat, in air conditioning and ducted heating. It’s a nightmare!

The amazing cure is the wet palette. Its simple goal is to maintain moisture in the paint at the same rate that it evaporates. Custom colours mixed p on the wet palette remain useable for days after they are originally combined and you can jump straight back into painting with your colours where you left off without having to remix them up again to match your previous work!

DIY Wet Palette Ingredients

Tupperware – it’s everywhere you want to be!

Baking Paper – also called parchment paper, greaseproof paper, etc.

Sponge – not the sort that lives in a pineapple under the sea.
The cost of ingredients is my favorite part of this project; it’s made from stuff that’s just lying around!

  • Tupperware container – EVERYBODY should have this stuff lying around. The Tupperware container, in this case, is about the size of your standard ham and cheese sandwich, any plastic container will do and they’re generally available in supermarkets for a couple of bucks for ten. Ideally, the container should be about the size of the sponge that will be used as the basis for my wet palette.
  • Baking Paper – The baking paper, which has many names based on your location, is a water-resistant paper that will allow the paint to sit above the sponge, absorb moisture and not soak into the sponge. This stuff is cut to a slightly larger size than the sponge on which it will sit.
  • Kitchen Sponge – It cost about 88 cents for a pack of five. We’re not talking high quality, here. It absorbs water and sits in the bottom of the plastic container. From previously observed results; it also starts to rot in the container after about six months of sitting in the water.
  • Water – You get it out of a tap.

DIY Wet Palette Construction

1. Fit the sponge into the container. If it’s a little too big, the sponge can be trimmed down with scissors.

2. Same goes for the baking paper. Cut it to size; about the same size and shape as the sponge it will sit on.

3. Here we hit the hard bit. How much water is too much water? A rough guideline seems to be enough water so that the sponge can absorb no more. This part is a bit experimental.

The finished product ready for paint …

Based on the process of evaporation and other factors like humidity, you may see the sponge dry out faster or slower. Keeping the lid on the plastic container between uses will reduce the amount of drying out of both the sponge and the paint on the wet baking paper.
