Primer
Primer is a preparatory coating applied to surfaces before painting or applying a topcoat. Its primary functions include:
Benefits of Primer
- Improved adhesion: Primer helps the topcoat adhere better to the surface.
- Uniform surface: Primer creates a uniform surface, reducing the appearance of imperfections.
- Stain blocking: Some primers are designed to block stains, preventing them from bleeding through the topcoat.
- Corrosion protection: Metal primers can provide corrosion protection.
Types of Primer
- Latex primer: Water-based primer suitable for most interior and exterior surfaces.
- Oil-based primer: Solvent-based primer often used for trim, doors, and windows.
- Epoxy primer: High-performance primer providing excellent adhesion and corrosion protection.
- Specialty primers: Designed for specific surfaces, such as metal, wood, or drywall.
When to Use Primer
- New surfaces: Primer is essential for new surfaces, ensuring proper adhesion and coverage.
- Dark or bold colors: Primer helps achieve even coverage and prevents multiple coats.
- Stained or damaged surfaces: Primer can block stains and imperfections.
- Surface preparation: Primer prepares surfaces for painting, ensuring a smooth finish.
