How Do You Mix Lime Paint?

Mixing lime paint involves combining several key ingredients in specific ratios to achieve the desired consistency and color. Several methods exist, depending on the desired outcome and available materials.

This method uses hydrated lime (lime putty or hydrated lime powder), water, and optionally, a natural pigment and alum salt.

  • Basic Ratio: A common ratio is 1 part alum salt : 1 part natural pigment : 10 parts lime putty or hydrated lime powder : 40 parts water. (Source: Provided reference material) Note that some recipes vary the water content.

  • Mixing Process:

    1. Dissolve the alum salt in a small amount of boiling water. (Source: Provided reference material)
    2. Gradually add the lime putty or hydrated lime powder to the water, stirring continuously to avoid lumps. A whisk, bar mixer, or electric paint stirrer can be used. (Source: Provided reference material)
    3. Incorporate the natural pigment, mixing thoroughly.
    4. Adjust the water content to reach a consistency resembling skim milk. (Source: Provided reference material)

  • Important Considerations: Always wear gloves and a mask while mixing lime paint. (Source: Provided reference material)

Method 2: Limewash with Regular Paint

This simpler method uses regular latex paint as a base, along with plaster of Paris and water. It's not a true limewash but creates a similar effect.

  • Ratio: Combine ½ gallon of paint with 3 cups of plaster of Paris and 1 cup of water. (Source: Provided reference material)

  • Mixing Process: Mix all ingredients until you achieve a pancake batter consistency. (Source: Provided reference material)

Method 3: Simple Limewash

This is the simplest approach, ideal for a basic limewash effect.

  • Ratio: Mix equal amounts (by volume) of lime putty and water, for example, 10 liters of each. (Source: Provided reference material)

  • Mixing Process: Combine the lime putty and water, stirring thoroughly until a smooth consistency is reached. (Source: Provided reference material)

Remember to always thoroughly mix the limewash before applying it to the surface. (Source: Provided reference material) The chosen method and ratio will affect the final color, texture and opacity of your lime paint.
