Wall Putty vs. Primer – Which Should You Use First?

When it comes to painting, many homeowners ask: “Should I use wall putty or primer first?” The answer lies in understanding what each one does.

Wall putty is like the foundation of a good paint job. Applied directly to plastered walls, it fills cracks, smooths out imperfections, and creates a flawless surface. Without putty, walls may look uneven and colours may not appear as bright.

Primer, on the other hand, comes after putty. It acts like a sealant, ensuring the paint adheres properly and does not soak into the wall. A primer layer also enhances paint durability and brings out the true vibrancy of colours.

Think of wall putty as preparing the wall, and primer as preparing the paint. Skipping either step can reduce the lifespan of your walls and affect the finish. For example, applying paint directly on putty without primer may lead to peeling and uneven absorption.

The best process is: plaster → wall putty → primer → paint. This ensures your walls remain smooth, vibrant, and long-lasting.
