Masterson Sta Wet Handy Palette Sponge Refill 22x18cm.
Wet the sponge. The sponge material has been compressed. Once you moisten it with water, it will expand to 1/4” thickness. The first time you use the sponge, rinse it thoroughly to remove any adhesives used during the processing of the sponge. Doing so will extend the life of the sponge. Then, fully saturate the sponge with COLD water. DO NOT WRING OUT THE SPONGE. Place the wet sponge in the palette tray. If the sponge is too large for the tray when it is wet, wring the sponge out and trim it to fit with a pair of scissors. Then saturate the sponge again with cold water and lay it in the tray.
