List of featured suppliers of PRIMERS: TYPES Undercoat Combined on Building Products Index
A primer refers to a preparatory coating that is applied to a surface before the actual paint or finish is applied. Primers come in various types and can be used to improve adhesion, cover up stains or imperfections, and prevent rust or other forms of corrosion. Undercoat refers to a secondary layer that is applied after the primer and before the final coat. Undercoats are used to smooth out the surface and provide a more uniform finish. Some primers and undercoats can be combined into a single product, which offers the benefits of both in a single application.
