What is limewash?

Limewash is a traditional interior and exterior finish for many stone and brick buildings, It lends a depth and luminosity to flat walls.Environmentally friendly and used for centuries, limewash is one of the original house paints, and so happens to be the most effective and appropriate finish available for traditional buildings:

A european house staple dating back to Roman times, limewash is made from limestone that’s been crushed, burned, and mixed with water to make a lime putty. The putty is aged and then thinned with water and colored with natural pigments. Limewash creates surfaces that are mottled and matte with a chalky texture something like suede.

The Lime Cycle

Making the paint

Limewash drying and limewash curing are two different things. Limewash needs a lot of water to cure properly and without it, your final product can end up being very powdery.

To ensure your wall cures properly, limewash needs to be applied in 3 different layers or coats: the primer, wash, and patina coat. The first and last coat being a very watery diluted version of your main mix.

Materials

• Acrylic mineral based primer + tools associated with typical paint application

• Hydrated lime (found at most hardware stores)

• Natural Rare Earth pigment in the colour of your choice

• Alum salt (also referred to as alum powder - found at Bulk Barn)

• Extra Wide Stain Brush

• Whisk

• Mixing bowls

• Optional: Grout and drywall mixer attachment for drill

Primer and Patina Coat

• Ratio = 1 part alum salt

• 1 part natural pigment

• 10 parts lime putty or hydrated lime powder
• 40 parts water

vour mix should resemble the consistency of skim milk

Mix one part alum salt with a little boiling water until dissolved. If you skip this step, the salt can cause your final mix to have a gritty texture.

Note: Make sure to wear proper PPE protection (gloves and a mask) when mixing your ingredients!

The wash Coat

This is the main middle coat which will produce most of the color. This mix is similar to first but with much less water.

Apply the wash coat to the wall using the same “x” pattern strokes. These stokes will be a visible part of the finished wall so take care to make stroke patterns that you’re happy to look at once the wall is done

The color of limewash will dry up to 60% lighter than the color it appears when first applied on the wall. If after the limewash has dried you feel the color is too light, you can add more natural pigment to your mix

*Note : Lime wash is water soluble so your finished wall cannot be washed with water. Instead, a fresh coat of limewash can be applied overtop of tired looking walls to bring them back to life.
