What Primer Means
Primer is a preparatory coating that improves adhesion, seals porous surfaces, blocks certain stains, and creates a more uniform base for finish paint.
Where It Is Commonly Used
Primer is commonly used over new drywall, bare wood, repaired areas, strong color changes, stained surfaces, and materials that need improved bonding.
Benefits
The right primer can reduce uneven absorption, improve color consistency, support adhesion, and help the finish coat perform as intended.
Important Considerations
Primer is not one universal product. Stain-blocking, bonding, masonry, drywall, and wood primers solve different problems, so the surface and failure risk should guide the selection.
