In terms of application, limewash is typically applied in multiple thin layers. Each layer is slightly translucent, allowing the natural color and texture of the brick to show through.
Lastly, limewash is commonly used on historic or older buildings, as it’s a traditional and authentic finish that complements the aged appearance of the brick.

If the mixture is too thick, you can add more water until you achieve the desired consistency.
It’s important to note that limewash is a breathable material, meaning it allows moisture to pass through. This makes it particularly suitable for use on porous surfaces such as plaster, brick, or unsealed wood. The lime putty acts as a binder, creating a durable and long-lasting finish.
When applying limewash, it’s common to use a brush or roller. Start from the top and work your way down, ensuring an even application. It’s also possible to dilute the limewash further if desired, by adding more water to create a translucent effect.
