For best results paint onto untreated, bare wood. Wood surfaces should be prepared with Earthborn Multi Purpose Primer and lightly sanded prior to application. Follow this with two full coats of Earthborn Eggshell. Sanding in between dried coats will provide an extra smooth finish.
If painting onto previously coated woodwork, especially those painted with oil-based or polyurethane paints or varnishes, sand well to a matt finish prior to painting. Surfaces that have been previously painted with oil-based gloss paints can be overpainted with Earthborn Eggshell provided the previous coating is thoroughly aged (usually around 3 years).
