Many confuse primer and putty – but both serve different purposes.
Wall Putty fills surface imperfections and gives a smooth base.
Primer is a sealing coat that ensures paint adhesion and long life.
Always apply putty → primer → paint.
Skipping primer causes patchy walls; skipping putty wastes paint.
Use Birla White Putty or Asian Paints Acrylic Primer for the best results in humid Tamil Nadu weather.
A proper base guarantees colour uniformity and durability for years.
