Choosing the right wall putty is crucial for achieving a smooth and durable finish on your walls. Wall putty serves as a preparatory layer before painting, filling imperfections, and ensuring an even surface. However, different surfaces require different types of wall putty to ensure optimal adhesion and finish. This guide will help you understand the various types of wall putty and how to select the right one for different surfaces.

Understanding Wall Putty

Wall putty is a white cement-based fine powder that is mixed with water to form a smooth paste. It is applied to walls and ceilings before painting to fill cracks, holes, and surface imperfections. The primary functions of wall putty are:

1. Surface Preparation: It provides a smooth and even surface for painting.
2. Adhesion: It improves the adhesion of paint to the wall.
3. Durability: It enhances the durability of the paint by providing a strong base.

Types of Wall Putty

There are mainly two types of wall putty available in the market:

1. Acrylic Wall Putty: Made from an acrylic or water-based solution, it is ready to use and does not require mixing with water. It is ideal for interior walls and provides a smooth finish.
2. Cement-Based Wall Putty: Made from white cement, it requires mixing with water to form a paste. It is suitable for both interior and exterior walls and provides excellent adhesion and durability.

It fills cracks and holes effectively, providing a smooth surface for painting. Its quick-drying property allows for faster completion of the painting process.

3. Exterior Walls

• Cement-Based Wall Putty: Exterior walls are exposed to harsh weather conditions, so cement-based wall putty is ideal for these surfaces. It provides strong adhesion and resistance to water and UV rays, ensuring a long-lasting and durable finish.

4. Interior Walls

• Acrylic Wall Putty: For interior walls, acrylic wall putty is preferred due to its smooth finish and ease of application. It provides a superior base for paint, enhancing the final appearance of the walls. It is also less prone to shrinkage and cracking compared to cement-based putty.
