This document reviews and evaluates the methodology that can be employed to assess the paintability of or paint compatibility with sealants used in building and construction. The term \u201cpaintability\u201d is used throughout this document and is a generic term to refer to the application of paint or a coating to a sealant.<\/p>\n
