IS THE EXTRA BOND REALLY NECESSARY FOR PAINTING OVER PREVIOUSLY FINISHED SURFACES?
We recommend using Extra Bond on anything other than bare wood. Milk Paint needs a porous surface to adhere to, and the use of Extra Bond will greatly help adhesion on non-porous surfaces. New sheetrock walls and plaster are actually too porous and should be primed with a flat latex primer, followed by a first coat of Milk Paint with Extra Bond added.
