When Extra Bond is added to Milk Paint, it improves adhesion to previously finished or other non-porous surfaces. Use for surfaces such as glass, baked enamel, primed metal, laminate, oil or latex paint, varnished, shellacked or polyurethaned surfaces and many plastics.
– Add Extra – Bond when painting over a non-porous or previously finished/painted piece of furniture. The Extra – Bond will ensure adhesion and give you better control over chipping. I highly recommend to always have the Extra – Bond on hand when using milk paint. Milk paint is known for its unpredictability when not using the Extra – Bond.
