How is oil-based paint categorized in terms of pH?

Oil-based paint is categorized as alkaline. This is due to the chemical composition of the pigments and binders used in oil-based paints, which typically have a pH level greater than 7. Alkaline substances can help in the adhesion properties of the paint and influence its drying and curing processes.

Understanding the pH of oil-based paints is important in the context of cleaning and restoration, especially when dealing with surfaces that may be affected by alkaline substances. In some situations, a more acidic or neutral approach is needed to protect underlying materials or to achieve a desired cleaning effect. Recognizing that oil-based paint is inherently alkaline helps professionals make informed decisions when dealing with cleaning agents and methods that should be used around surfaces coated with such paints.
