primer coat
Definition
Noun A primer coat is the first layer of paint, varnish, or sealant applied to a surface. Its primary purpose is to prepare the surface for subsequent coats by ensuring proper adhesion, providing a uniform base, and sometimes sealing or blocking stains.
Usage
The term primer coat is used specifically in the context of painting, woodworking, and construction. It refers to the foundational, preparatory layer. * Applying a primer coat is essential for painting over bare wood or metal. * The primer coat must be completely dry before adding the topcoat. * A good primer coat will hide dark colors and prevent them from showing through the new paint.
Advanced Usage
- Primer-sealer: A type of primer coat that also seals porous surfaces to prevent excessive absorption of the topcoat.
- Stain-blocking primer: A specialized primer coat designed to prevent stains (like water, smoke, or ink) from bleeding through the finished paint.
