A few years ago, I decided to repaint my living room. I picked a beautiful shade, got the best paint, and did the job myself. It looked perfect at first, but within months, the paint started chipping and peeling. The smooth, flawless finish I loved was now covered in cracks and rough patches. What went wrong?
The missing step—Primer!
Just like a foundation before makeup, primer prepares the surface before painting, ensuring smooth finish. If you’ve ever wondered, ‘Do I really need a primer before painting?’ This blog is for you.
A primer for painting is a preparatory coating applied before paint to ensure better adhesion, and protection of surfaces. Think of it as a base layer that helps paint stick better and last longer.
Primers come in different formulations depending on the surface—wood, metal, concrete, drywall, and even exteriors. Using the right primer for walls or outdoor primer can make a significant difference in how your paint job turns out.

Using the best primer before painting has multiple benefits:
• Better Adhesion – Paint sticks better and stays put for longer.
• Seals the Surface – Prevents moisture absorption, reducing issues like peeling and dampness.
• Smooth Finish – Hides imperfections and provides a clean canvas for the final coat.
• Saves Paint & Money – Without a primer, walls can soak up paint, requiring extra coats.
Different surfaces require different types of primers. Here’s a breakdown of the most common ones:
a. Oil-Based Primers
• Great for stains, wood, and metal surfaces.
• Blocks tannins from bleeding through (common with wood).
• Dries slowly but provides excellent smooth finish
b. Water-Based Primers
• Ideal for drywall and previously painted walls.
• Dries faster than oil-based primers.
• Low odor and easy to clean up.
c. Shellac Primers
• Best for blocking severe stains (smoke, water damage, ink, grease, etc.).
• Fast-drying and provides strong adhesion.
• Can be used on wood, metal, and walls.
Selecting the best primer depends on:
1. Surface Type – Wood, metal, drywall, or concrete? Choose a primer accordingly.
2. Condition of the Wall – New drywall? Use a water-based primer. Stained walls? Use a shellac primer.
3. Interior vs. Exterior – An outdoor primer is a must for exterior walls to withstand weather conditions.
4. Type of Paint – Some primers work best with specific types of paint. Check compatibility before applying.
For high-performance exterior priming, Birla White ActivCoat Exterior Primer is a great option. It ensures strong adhesion and long-lasting protection for outdoor walls.
Here’s a step-by-step guide to applying primer before painting:
Step 1: Prepare the Surface
• Clean the surface thoroughly, removing dust, grease, and peeling paint.
• Sand any rough areas for a smooth finish.
Step 2: Choose the Right Primer
• Pick an oil-based, water-based based on your surface.
Step 3: Apply the Primer
• Stir the primer well before using.
• Use a roller or brush to apply an even coat.
• Allow the primer to dry completely (typically 2-6 hours).
Step 4: Sand (If Needed)
• Lightly sand the primed surface for extra smoothness before painting.
Step 5: Apply Paint
• Once dry, proceed with your desired paint color.
