Priming Vinyl Siding

Our Bullseye 123 and SmartPrime primers should be suitable for use on sound vinyl siding.   As siding can vary from manufacturer to manufacturer, it is suggested to conduct a test application in an inconspicuous area to ensure proper adhesion.   Full cure and adhesion with these primers will develop in 7-10 days, so it is important to allow the primer to cure completely before reviewing the test area and proceeding with a full application.
