Applying oil based paint over latex is a common scenario in both residential and commercial painting projects, often arising when refreshing a trim, repurposing a surface, or correcting a previous error.
Understanding Oil Paint Adhesion Issues on Latex Surfaces
" Latex paint cures as water evaporates, leaving a slightly porous, rubbery surface that typically bonds well with other latex paints. Without proper adhesion promoters or surface preparation, the slick, non-porous nature of a cured latex coat can cause an oil-based topcoat to peel or chip prematurely.
Synthetic brushes are generally not compatible with oil-based solvents and will stiffen or deteriorate quickly. The Critical Role of Primers A high-quality bonding primer is arguably the most crucial element in a successful oil-over-latex project.
