For use for stencilling with waterbased paints. This is simply another way to apply paint through your stencil (instead of using a brush). It is good for single colour work. If working with more than one colour, you will have less control over where the colour goes than with a stencil brush. The finish will be more rustic and less sophisticated than you get when using a stencil brush. The stencil sponge measures 4″ (76mm) square (1″/25mm thick). It can be used as is for larger areas or cut up into smaller pieces. Here’s another use for stencil sponges: they are excellent for applying basecoat paint and varnish to pieces without leaving brushmarks. They are also good for applying paint to ceramics.
