Wall Putty vs POP: Which is Better for Wall Finishing?
Introduction
Wall finishing plays a major role in the durability, appearance, and overall quality of any residential or commercial space. Proper surface preparation is essential to achieve smooth walls, long-lasting paint performance, and an attractive finish. Two commonly used wall finishing materials are Wall Putty and POP (Plaster of Paris).
Understanding the difference between wall putty and POP helps in selecting the right material for construction, renovation, repainting, and decorative projects.
What is Wall Putty?
Wall putty is a white cement-based or acrylic-based finishing material applied to walls before painting. It smoothens wall surfaces, fills pores and minor cracks, improves paint adhesion, and creates a strong paint-ready base.
- Interior wall preparation
- Exterior wall finishing
- Surface smoothening before painting
- Improving paint durability
- Enhancing wall strength
- Reducing paint consumption
White cement-based wall putty is preferred for excellent bonding strength, moisture resistance, and durability.
What is POP (Plaster of Paris)?
POP is a gypsum-based material commonly used for decorative and interior applications. Known for its smooth texture, it allows for decorative designs and false ceilings.
- False ceiling work
- Decorative wall designs
- Ceiling patterns and mouldings
- Cornices and artistic finishing
- Surface repair applications
- Interior decorative elements
POP is preferred for aesthetic and decorative purposes rather than surface strengthening or paint preparation.
Wall Putty vs POP: Understanding the Basic Difference
Wall Putty: Mainly used to prepare walls before painting and to improve wall durability.
POP: Mainly used for decorative and design applications inside buildings.
