A good topcoat can only perform as well as the surface beneath it. In 2026, more attention is being given to quality primer systems because they improve adhesion, seal porous surfaces, and help the final paint finish last longer — especially on older or previously painted walls.
Why Primer Systems Matter
- Better Adhesion
Primer creates a strong bond between the surface and the topcoat. - Improved Coverage and Uniformity
It reduces the number of topcoat layers needed and helps colour look even. - Longer-Lasting Finish
Proper priming supports better durability and reduces premature peeling or patchiness.
Practical Advice
- Use a suitable primer on new plaster, porous walls, or surfaces with stains
- Allow primer to dry fully before applying topcoat
- Match the primer type to the surface and the paint system
