A simple paint test to determine whether dry / old paint on a previously painted surface is solvent based or water based.
Solvent Based / Water Based Paint Test
Dip a clean cloth into some methylated spirits and rub it on the paint surface. If the paint comes off on the cloth, then it is water based. If not, it is a solvent based coating that was previously used on the surface. Water based paints are not resistant to chemicals and solvents.
And that’s it! Knowing what paint was previously used on a surface is essential for knowing how to proceed with repainting a surface. Following this simple solvent based / water based paint test will provide you with this information and will help us with advising you how to best proceed with repainting your surface.
