Chroma Solvent Finishing Varnishes are designed to protect finished acrylic or oil paintings. Because of their ease of use, we recommend using a solvent over a water-based varnish for artists new to varnishing.
- Invisible Solvent Finishing Varnish maintains the low sheen look and does not alter the surface quality of a painting. It can also be used on oil paintings as a “retouch” varnish, while waiting out the advisable 3-6 month period for an oil painting to cure before applying a heavier protective varnish.
- Satin Solvent Finishing Varnish contains a matting agent and the container needs to be shaken before use to make sure it is evenly suspended. For full bottles, remove some varnish so you can shake the contents easily, then return to the full bottle before using. Satin varnishes should never be diluted with turpentine, because the ratio of matting agent to acrylic is critical.
- Gloss Solvent Finishing Varnish can be used for a more oil paint like look. Apply as is for a full gloss, usually one coat. To reduce gloss, add mineral turpentine to your taste. Try two parts varnish to 1 part turpentine, up to 1:1 for less sheen. NOTE: This varnish contains an anti-mold additive that is diluted when you add turpentine, so to maintain the mould protection for tropical conditions dilute with Invisible Varnish instead.
These three varnishes are non-yellowing, self-leveling and protect against mold. They are strippable, which allow your painting to be cleaned more easily at a later date by swabbing with mineral spirits. Be sure to apply in a well-ventilated area.
