Blick Product Info Tip of the Week - Substrates for Encaustics
Substrates for Encaustics
What surfaces are best for use with encaustics? Anything that has the following three qualities:
It must be absorbent
Must withstand 150 to 175 degree heat
Must be rigid
Specialty boards intended for use with encaustics are available, but they are not the only substrate that can be used with encaustics. Untempered Masonite, plywood, illustration board and even heavy watercolor paper (which can be mounted for rigidity) can all be used. Wood and other heavier boards are better for thick applications, illustration boards and paper can be used with thinner applications. Caution should be used with paper if it is allowed to rest directly on a heated surface, as prolonged heating can cause brittleness or browning.
Stretched canvas is not a suitable substrate for encaustics. The encaustic paint can crack over time as the canvas flexes and if it is applied thickly it can cause the canvas to sink in the center.
Q. Do I need to prime my surface for use with encaustics?
A. Since you will be choosing a surface that is already absorbent, it does not need to be primed for use with encaustics. In fact, primers such as gesso can actually reject encaustics.
