How to whitewash walls with lime?

Whitewashing walls with lime involves creating a thin, paint-like mixture and applying it to the wall. Here’s how to do it:

Preparing the Limewash

The key to a good limewash is achieving the right consistency.

Initial Mixing:
- Start by mixing equal amounts of lime putty and water. For example, use 10 liters of lime putty with 10 liters of water.
- This initial mix will be thick, almost like a very loose paste.
Adjusting Consistency:
- Gradually add more water to the mixture.
- The goal is to achieve a consistency similar to single cream.
- Continue adding water in small increments until you reach the desired thin paint-like consistency.
Key Note: The reference states, "You can then add more water until you reach a suitable consistency. You are looking to achieve a thin paint consistency like single cream."

Surface Preparation: Ensure your wall is clean and free of any loose material.
Application: Using a large brush, apply the limewash mixture to the wall. Apply in even strokes.
Multiple Coats: Allow each coat to dry completely before applying the next. You may need two or three coats for an even, opaque finish.
Drying Time: Drying time can vary depending on conditions such as temperature and humidity.
Final Look: The final look should be a soft, matte finish typical of limewash.

Lime Putty: Use good quality lime putty for the best results.
Safety: Wear gloves and eye protection when working with lime.
Practice: If it’s your first time, consider practicing on a smaller area first.
