When and Why to Use Primer
Primer is a preparatory coating applied to surfaces before painting. It ensures better adhesion of the paint, increases durability, and provides additional protection to the material being painted. Using primer can make a huge difference in the final look and longevity of your project.

When Should You Use Primer?
1. New Drywall
Drywall is porous and can absorb paint unevenly, leaving a patchy finish. A drywall primer-sealer will help create a smooth, even surface for painting.
2. Wood Surfaces
Bare wood often contains knots and tannins that can bleed through paint. Use a stain-blocking primer to seal and prevent discoloration.
3. Painting Over Dark Colors
If you are painting over a dark or vibrant color, primer can prevent the old color from showing through and reduce the number of paint coats needed.
4. Stains or Repairs
If the surface has stains (like watermarks, smoke, or grease) or repaired areas (like spackled holes), a primer will help conceal imperfections and prevent them from resurfacing.
5. Glossy Surfaces
Painting over slick surfaces like glass, tiles, or glossy paint requires primer to create a surface the paint can stick to. Look for bonding primers for these situations.
6. Exterior Surfaces
Exterior primers are formulated to protect against harsh weather conditions and help the paint last longer. Always prime when painting exterior wood, masonry, or metal.
Types of Primer
• Oil-Based Primer: Excellent for wood and surfaces prone to stains. Use with oil-based or latex paints.
• Water-Based Primer: Ideal for drywall and most indoor surfaces. Compatible with latex paints.
• Stain-Blocking Primer: Best for covering stains, knots, and odors.
• Bonding Primer: Designed for slick surfaces like tiles and laminates.
• Shellac Primer: Great for high-damage areas; blocks stains and odors effectively.
Why Should You Use Primer?
1. Improved Adhesion: Ensures that the paint adheres properly to the surface, reducing peeling and chipping over time.
2. Enhanced Durability: Protects the surface underneath and ensures the paint lasts longer.
3. Uniform Finish: Creates an even base, especially when switching from dark to light colors.
4. Cost Savings: Reduces the number of paint coats needed, saving time and money.
Conclusion
Using primer is a simple step that yields significant results. Whether you’re painting a wall, cabinet, or exterior, choosing the right primer ensures a professional-quality finish that stands the test of time.
