Environmental conditions are important to the quality of the cure, and to achieve the best clarity and surface finish. For the epoxy to cure fully, the ambient temperature must be between 65°F and 80°F. When pouring for larger projects, such as slabs or tables, do not exceed a pour depth of ½” to 1″ to prevent yellowing or excessive heat from the cure. Step pouring with multiple layers will achieve the best results. This resin is not designed for continuous UV exposure. If the item will be used outdoors, the cured surface must be coated with a UV-resistant finish (like clear varnish) to prevent yellowing and fogging.
