Hey Friends! Answering another one of the questions that we get frequently. Is it okay to paint over polyurethane? This information will work for water based products & more specifically Chalk Type Paints. These paints are formulated to have a strong adhesion. While we may all relate to the allure of quick and easy. When painting anything it is best to remember that your paint is only as good as what it is sticking to.
