These lightweight boards provide a simple and inexpensive alternative to canvas. They are made up of stiff light corrugated plastic board which may need priming even for an acrylic. Anita has used these boards with a watercolour primer to paint on with watercolour.
Unless the product specifically says it is for watercolour then the chances are it is not suitable. Watercolour needs an absorbent surface to work well. They will slip off a non-porous surface.
There are products on the market which will allow you to work on non-porous surfaces with watercolour, these are called grounds:
Daniel Smith Watercolour Ground; Ready to use straight from the container it has a thick consistency and one coat will cover most surfaces.
It works on everything you can think of, from plastic and cloth to tin and stone, giving you an incredible range of new possibilities. But best of all you can rescue a flawed painting plus lift and scrub without damaging the picture's surface.
It is available in Black, White, Buff Titanium, Clear, pearl and Gold.
Schmincke Watercolour Ground offers a fine or coarse surface for you to work on if you would like to vary the texture of your painting.
Acrylic on the other hand as very versatile and will work well on most surfaces.
