How to Limewash Brick (Interior & Exterior Guide)

event how to limewash

Limewashing brick is one of the most timeless ways to update a space without covering up the natural character of the masonry. Whether you’re refreshing a brick fireplace, an interior accent wall, or the entire exterior of a brick home, limewash gives you an old-world finish that gets better with age. Here’s a step-by-step guide to doing it right.

First: What Makes Limewash Different From Paint?

Before we jump into the how-to, it helps to understand why limewash behaves differently. Limewash is made from crushed limestone and water, creating a mineral-based coating that:

  • Soaks into porous brick instead of sitting on top
  • Creates a breathable finish (important for masonry)
  • Wears naturally over time instead of peeling
  • Leaves a soft, chalky, textured appearance
  • Because it bonds with the brick, proper prep and application matter — but the process is very DIY-friendly when done correctly.

Where You Can Limewash Brick

The key requirement: real, porous brick or masonry. Limewash does not properly adhere to sealed, painted, or non-porous surfaces without first applying the proper primer. Limewash works beautifully on:

Interior Limewash

  • Fireplaces
  • Brick accent walls
  • Exposed brick in lofts or basements

Exterior

  • Full brick homes
  • Brick chimneys
  • Garden walls and facades

Tools & Materials Needed for Limewashing

  • Limewash (premixed or powdered)
  • Large masonry or block brush
  • Spray bottle or garden sprayer (for water)
  • Drop cloths
  • Painter’s tape
  • Protective gloves and eyewear
  • Stir stick or drill mixer
  • Optional: Natural sea sponge or rag (for a distressed effect)

9 Steps to a Proper Limewash

Step 1: Check If Your Brick Is Suitable

  • Limewash needs to soak in. Test your brick by spraying it with water
  • If the water absorbs quickly, you’re good to go
  • If it beads up, the surface may be sealed or previously painted
  • If the brick has paint or a heavy sealer, that coating usually needs to be removed before limewashing

Step 2: Clean the Brick Thoroughly

Dirt and dust can prevent limewash from bonding evenly.

For interior brick:

  • Vacuum loose dust
  • Wipe down with a damp cloth

For exterior brick:

  • Use a hose or low-pressure wash
  • Remove dirt, mildew, and debris
  • Avoid harsh chemical cleaners that can leave residues
  • Let the brick dry, then lightly dampen it again just before application

Step 3: Protect Surrounding Surfaces

Limewash is watery and can splatter.

  • Tape off trim, mantels, windows, and siding
  • Lay drop cloths on floors and landscaping
  • Wear old clothes — this stuff is messy but worth it

Step 4: Dampen the Brick

This step is crucial. Before applying limewash, mist the brick with clean water. The surface should be damp but not dripping. This slows absorption and helps you achieve a softer, more even finish.

Step 5: Mix the Limewash

If using powdered limewash:

  • Mix according to manufacturer directions
  • Aim for a consistency similar to whole milk

If using premixed limewash:

  • Stir thoroughly — minerals settle at the bottom
  • You can dilute with more water for a lighter, more translucent look

Step 6: Apply the First Coat

Use a large masonry brush and work in small sections.

Technique tips:

  • Apply in random, crisscross strokes
  • Push the limewash into mortar joints and brick texture
  • Keep a “wet edge” to avoid harsh lap lines
  • It will look darker when wet and lighten significantly as it dries.

Step 7: Customize the Look (Optional)

One of the best things about limewashing brick is how customizable it is. Within the first 10–30 minutes, you can:

  • Distress it by dabbing with a damp sponge
  • Soften areas with a wet rag
  • Create variation by removing some limewash from brick faces

This is how you get that classic, uneven, aged European finish.

Step 8: Let It Dry

As it dries, the color softens and becomes more matte and chalky. Dry time depends on temperature and humidity, but generally:

  • Touch dry: a few hours
  • Fully cured: 24–48 hours

Step 9: Decide If You Want a Second Coat

After it dries, step back and evaluate. Add another coat if you want:

  • More coverage
  • A brighter white or lighter tone
  • Less brick color showing through

Always dampen the brick again before applying additional coats.

Interior vs. Exterior Limewashing: Key Differences

Interior Brick

  • Easier to control application
  • Less weather impact
  • Mostly aesthetic wear over time

Great for fireplaces and feature walls where you want warmth and texture without heavy contrast.

Exterior Brick

  • Must be applied in mild weather (not freezing or extreme heat)
  • Avoid rain during and right after application
  • Naturally patinas over time from sun and weather exposure

Exterior limewashed brick ages beautifully and requires very little maintenance.

How Long Does Limewash Last on Brick?

One of the biggest advantages of limewashing brick is longevity. Because it penetrates masonry instead of forming a film:

  • It doesn’t peel like paint
  • It slowly fades and softens over years
  • It can be reapplied without heavy scraping or sanding

On exteriors, expect gradual weathering that adds character rather than damage.

Common Mistakes to Avoid

  • Applying to sealed or painted brick: Limewash can’t absorb properly and may fail.
  • Skipping the dampening step: Dry brick can cause blotchy, overly heavy absorption.
  • Using a roller instead of a brush: Rollers don’t push limewash into mortar joints or texture well.
  • Expecting a perfectly uniform finish: Limewash is meant to have variation — that’s part of the charm.

Is Limewashing Brick DIY-Friendly?

Yes, for interiors and exterior areas. For full exterior homes or very tall surfaces, hiring a pro can make sense for safety and efficiency. However, many homeowners successfully limewash:

  • Fireplaces
  • Interior brick walls
  • Small brick facades

Limewashing brick doesn’t hide the character of masonry — it enhances it. The result is a breathable, mineral finish that feels warm, historic, and effortlessly stylish. Stop in at a Loconsolo Paints store near you for Limewash product and guidance on projects.
