Considering the materials used in encaustic paintings, beeswax and damar resin, the pairing creates a product resistant to moisture, protecting their quality from a larger variety of environments. However, despite this shielding content, encaustics require careful handling to preserve their beauty.
Hanging an encaustic painting indoors and away from direct sunlight or alternative heat sources allows for safe durability. Only temperatures reaching 150 degrees Fahrenheit or 65 degrees Celsius would negatively affect the artwork. Conversely, the artwork should also avoid temperatures below -22 degrees Fahrenheit or -33 degrees Celsius.
Similar to other art mediums, encaustic paintings require a minimum six months curing process to allow completion of the oxidation process. During this period, moisture within the material will surface, often creating a mild haze or a "bloom," causing a faded or murky appearance. Should this occur in your artwork, you can buff it with gentle but firm pressure using a soft cloth or a pair of clean pantyhose in circular motions just until the bloom disappears. Over time you may need to repeat the buffing process once or twice before it is fully cured.
