MSA Varnishes require thinning before application, water won't work, and improvising with hardware store solvents risks clouding or uneven coverage. Golden formulates MSA Solvent specifically to maintain the optical clarity and working properties of their mineral spirit acrylic varnishes. The solvent thins varnish to proper brushing or spraying consistency while evaporating cleanly without residue or haze.

Beyond preparation, this solvent becomes essential for conservation work. MSA varnishes are designed as removable protective layers, allowing future restoration without disturbing the underlying paint. When that time comes, MSA Solvent dissolves the varnish layer gently and completely, preserving the artwork beneath. This reversibility matters for archival pieces and commissioned work where long-term preservation protocols apply.

Use MSA Solvent for cleaning brushes and tools immediately after varnishing, before mineral spirit acrylics cure to their permanent state. The formulation matches Golden's varnish chemistry precisely, ensuring compatibility across their MSA product line. Keep this solvent on hand whenever working with MSA Varnishes, proper thinning and the ability to remove or restore varnish layers later depend on having the right solvent for the system.
