Primer
A preparatory coating applied before paint to improve adhesion, block stains, and ensure uniform color.
Why It Matters for Homeowners
Why it matters: skipping primer is the most common shortcut on a paint job, and it is the most expensive one to redo. Bare wood, fresh stucco, or a stain-blocked wall all need the right primer or the topcoat will fail within a few years. The categories worth knowing: stain-blocking for water-marked drywall, adhesion primer for slick or chalky surfaces, and tinted primer when going from light to dark.
