Why Primer is a Must-have for long-lasting paint finishes in 2025

The Fundamental Role of Primers

Primers serve as the preparatory layer applied to surfaces before painting. They are designed to adhere to various substrates, creating a uniform base that enhances the adhesion of the topcoat. This process not only ensures that the paint binds effectively to the surface but also contributes to a smoother and more even finish.

Why Primer for Walls is a Must-have for long-lasting paint finishes in 2025

1. Enhanced Adhesion: primers create a bonding layer that allows the paint to adhere more securely to the surface, reducing the likelihood of peeling or chipping over time.
2. Improved Coverage and Opacity: By providing a consistent base color, primers can enhance the true tone of the paint, ensuring that the final color appears vibrant and uniform.
3. Surface Sealing: Primers can seal porous surfaces, preventing the topcoat from being absorbed unevenly, which can lead to blotchy finishes.
4. Stain Blocking: They can prevent stains or tannins from bleeding through the paint, maintaining the integrity of the finish.
5. Moisture Resistance: Some primers offer moisture-resistant properties, protecting surfaces from humidity and potential water damage.

Primer before putty: The secret to everlasting walls

It is recommended to apply primer before wall putty when preparing walls for painting for the following reasons

• Smooths surface: Primer creates a clean, smooth surface for applying wall putty. 
• Seals imperfections: Primer seals cracks and other imperfections, which helps the putty adhere better. 
• Prevents peeling: Primer helps prevent the putty from peeling or chipping over time. 
• Prevents cracks: Primer helps prevent cracks from showing up in the wall. 

Here are some tips for applying wall putty:

• Allow the primer to dry completely before applying the putty. 
• Apply the first coat of putty vertically, from bottom to top. 
• Let the first coat of putty dry for 6 to 8 hours. 
• Gently rub the surface with sanding paper to remove loose particles. 
• Apply a second coat of putty. 
• Let the surface dry completely, preferably overnight. 
• After the wall is completely dry, rub the surface with sandpaper to create a glossy finish. 
• Drying time may vary depending on temperature, humidity, and the thickness of the coat.
