The Solvent Test The most reliable hands-on test involves a common solvent. Always dry oily rags flat or submerge them in water before disposing of them in a sealed metal container to prevent igniting the linseed oil residues.

Recognizing these core properties helps frame the subsequent testing methods. Look for fine cracking patterns known as "alligatoring," which are common in aged oil paints due to the drying process.
These products may test weakly with solvents or dry faster than traditional oils. If the area has never been cleaned with anything stronger than soap and water without damaging the finish, it is a strong indicator of an oil-based product.

Water-based paint will largely remain unaffected by these solvents but may clean up instantly with a damp rag. When in doubt, consult the original documentation or contact the property manager or previous painter for the specific product name and year of application to ensure compatibility with your new coating.
