Methods of blocking stains on a substrate to be painted, and composites suitable for use in such methods

摘要: Methods of blocking stains on a substrate to be painted are disclosed, as stain-blocking composites that useful according the disclosed methods. In broad aspect, methods include steps contacting stained portion with dry film layer; applying pressure layer cause adhere and at least adjacent substrate; subsequently coating one or more additional liquid layers. Stain described release layer, which is applied; can clear pigmented, serves block stain; an optional adhesive intended assist in adhering substrate.
