What is Putty?

Putty is a thick paste, often made from a combination of chalk, oil, and sometimes resin. It's used to fill gaps, cracks, and imperfections in surfaces before painting. Think of it as a filler that creates a smooth base.

Why Use Putty?

Using putty has several benefits. Here are the top reasons:

  1. Fills Imperfections: Putty can fill holes and cracks, making walls look flawless.
  2. Enhances Adhesion: A smooth surface ensures paint adheres better.
  3. Improves Appearance: It gives your walls a clean, professional look.
  4. Prevents Peeling: Properly prepared surfaces help avoid paint peeling later on.

When Should You Use Putty?

It's best to use putty in these situations:

  • When walls have visible holes or dents.
  • Before painting over textured surfaces.
