What Is a Primer?

Primer is a preparatory coating applied before the final layers of paint. It helps the paint adhere better, ensures smoother coverage, and improves durability. Primer for painting is essential for almost every project, especially if you’re working with new surfaces or drastic color changes.

Do You Need a Primer Before Painting?

In most cases, yes, primer is necessary before painting. The only exception is when using paint with built-in primer. Even then, this is only effective on walls in good condition. Here are situations where primer is crucial:

• Unfinished wood surfaces: Primer for wood is essential as it seals the wood. It ensures better paint adhesion. This is especially true on knotty wood. Zinsser PrimeCoat2

• 
  

• Switching from oil-based to latex paint: When applying latex paint over oil-based paint, a bonding primer ensures the paint sticks. Benjamin Moore® Fresh Start® Multi-Purpose Oil Based Primer

• Painting new drywall: Use a PVA primer (polyvinyl acetate) on drywall to avoid blotchy results. It seals the surface and makes the final paint look even.

• 
  

• Covering dark colors: When painting over dark or bold colors, use primer. It helps achieve the final shade with fewer coats of paint.

• 
  

• Painting over wallpaper: Wallpaper can be tricky to paint over. Using a primer for painting over wallpaper ensures the new paint adheres smoothly without bubbling or peeling.

Case Study:
At Daeco Painting, we once tackled a home. The former owners had used a bright red in the living room. Our team used a tinted primer to cover the red. Then, we applied a soft neutral color. This saved time and ensured the final result was flawless.

Types of Primer

Understanding the different types of primer is key to selecting the best one for your project. Here’s a breakdown:

• Oil-Based Primer: This type is ideal for covering stains. It is often used for painting over 

• stained wood or covering water damage. It’s durable but takes longer to dry and requires oil-based paint for top coating.

• Latex Primer: Latex-based primers are easy to use, quick-drying, and work well on drywall and earlier painted surfaces. They’re also excellent for projects where you’re switching to latex paint.

• Specialty Primers: There are primers designed for specific tasks. Some examples include primer for painting over dark colors, mold-killing primer, and primers for metal surfaces. Always choose a primer based on the condition of your surface.

How Many Coats of Primer to Use

The number of coats depends on the surface and type of paint. Here’s how to decide:

One Coat of Primer:

• Painting over similar colors.

• Going from light to dark.

• Smooth, well-maintained surfaces like metal.

Two Coats of Primer:

• Painting unfinished wood or new drywall.

• Covering drastically different colors, like dark to light.

• Painting over wallpaper or damaged surfaces.

Tip: When covering a dramatically different color, ask the paint store to tint the primer. The tint should match 50% of your final paint color.

Three Coats of Primer (Rare):

• Major stains or uneven surfaces, like masonry, plaster, or stained wood.

• Painting over water damage on ceilings or walls.

Real-Life Benefits of Primer

At Daeco Painting, we’ve seen the difference primer makes. On one job, a homeowner wanted to cover stained wooden cabinets with a fresh coat of white paint. After sanding and applying two coats of stain-blocking primer, the paint went on flawlessly and the cabinets looked brand new. Skipping this step has led to discoloration and peeling.
