Question 1

Will my Encaustic Painting Melt?

Accepted Answer

An encaustic painting is stable in a temperature range of approximately 40-120°F. Wax is more fragile in the cold and becomes extremely brittle in freezing temperatures. If you would drop the painting in cold temperatures it will shatter. The paintings will begin to shift at 120°F. The wax begins to be workable at 150°F, and it becomes liquid at 162°F. Very hot days can soften the wax somewhat, but will cause no real damage.

Question 2

What are the guidelines for hanging my Encaustic Painting?

Accepted Answer

Do not hang your painting in direct sunlight.  You should never put any fine art in direct sun, but with encaustic there could be more immediate consequences. Also do not hang your painting near a heat vent or incandescent lighting. If you are nervous about the placement of the painting just feel the surface.  If it is warm the painting needs to be moved.  It should always feel cool to the touch.

Question 3

What about transporting my Encaustic Painting?

Accepted Answer

If you must transport the painting in hot or cold weather simply cover the entire wax surface with wax paper first, then cardboard, and then some form of insulation like bubble wrap.  When the painting is at room temperature unwrap the painting and remove the wax paper.  In hot weather the wax paper may stick to the painting but will cause no damage as long as it is removed at room temperature.

Question 4

What if I want to change the frame on the painting?

Accepted Answer

Avoid putting an encaustic piece under glass when framing. If covered in glass and hung in direct sunlight, the glass will magnify the light and the space between painting and glass can heat up dramatically causing the painting to melt and shift. The paints have a damar resin in its formula; this cures and hardens the wax over time making the paint less vulnerable to damage. It's like varnishing the painting from within...so it doesn't need glass. However, you can still take your fingernail and scratch the surface.

Question 5

What about caring for my Encaustic Painting?

Accepted Answer

You may need to buff your painting when it seems dull or hazed over.  The painting should always be shiny. When the painting is "young" or recently finished, it has not yet had time to cure and harden. It will therefore go back to a matte looking surface after buffing the first few times. As time goes by and the mixture has had a chance to cure and harden, (could take up to 6 months) it will keep its buffed polished look. At this point, it also sheds dust and dirt more readily. When the painting is at room temperature or cooler take a soft 100% lint-free cotton cloth (they are used for buffing cars) and lightly buff the painting. Do not buff the painting if it is over 75 degrees. Do not buff hard enough to create heat.

Question 6

Is Encaustic Painting durable?

Accepted Answer

Encaustic paints are perhaps the most durable form of painting, evidenced by the Faiyûm mummy portraits in Egypt, which have survived over 2000 years without cracking, flaking, or fading.  Wax has several inherent qualities that allow it to withstand the test of time: it is a natural adhesive and preservative; it is moisture resistant, mildew and fungus resistant, and unappetizing to insects.  Wax paint also does not contain solvents or oils so they will not darken or yellow with age.  Leaving the painting as fresh as the day it was painted.
