Whitewashing brick is one of the most cost effective ways to transform a dark, heavy fireplace or accent wall into a light, airy feature that brightens an entire room. Unlike paint, which forms a solid film on the surface, whitewash sinks into the porous brick and creates a translucent, chalky finish that preserves the natural texture and character of the masonry. Whether you are tackling a dated red brick fireplace in your living room or want to soften an entire interior brick wall, this technique delivers professional results with basic supplies and a weekend of effort. Before you begin, review our guide on whitewashing brick with masonry materials and techniques to understand which supplies work best for your specific brick type.
What Is Whitewashing and Why Choose It Over Paint
Whitewashing is a centuries old finishing method that uses a dilute mixture of latex paint (or traditional lime) and water to create a semi transparent coating. The mixture seeps into the pores of the brick rather than sitting on top, which means the final appearance is soft, matte, and naturally variegated. Each brick absorbs the wash differently, producing subtle tonal variations that mimic the look of aged, weathered masonry.
Whitewash Versus Solid Paint
The main difference between whitewashing and painting brick comes down to breathability and texture. Solid latex or acrylic paint forms a non porous barrier that traps moisture inside the brick. Over time, trapped moisture leads to spalling, efflorescence, and peeling. Whitewash, by contrast, allows moisture vapor to escape because the coating remains porous. This makes whitewash a smarter choice for brick that is exposed to humidity, temperature swings, or any below grade condition.
| Feature | Whitewash | Solid Paint |
|---|---|---|
| Breathability | High, moisture escapes | Low, traps moisture |
| Texture visibility | Brick texture remains visible | Texture is covered completely |
| Application difficulty | Easy, forgiving | Requires precise rolling and cutting |
| Long term removal | Can be scrubbed off with water | Requires chemical strippers or sandblasting |
| Cost per square foot | Low, uses minimal paint | Higher, requires full paint coverage |
| Best for | Fireplaces, accent walls, exterior brick | High traffic areas needing durability |
Limewash Versus Latex Whitewash
Traditional limewash is made from hydrated lime and water. It produces the most authentic aged look and is extremely breathable. However, limewash requires careful mixing and curing, and it can powder off if not applied correctly. Modern latex whitewash, which is simply latex paint thinned with water, offers easier application, better adhesion, and more consistent color. For most DIY homeowners working on interior brick, latex whitewash is the practical choice. If you are working on an exterior surface, consider the masonry specific approach covered in how to paint brick, MDF, metal, and plastic surfaces at home for additional surface preparation tips.
Supplies and Materials You Will Need
Gathering the correct supplies before you start makes the difference between a smooth project and a frustrating one. Whitewashing requires fewer materials than painting, but each item plays a specific role in achieving an even, durable finish.
Essential Materials List
- Flat or matte latex paint in white or off white (one quart covers approximately 100 square feet of brick)
- Clean water for thinning the paint
- Large mixing bucket and stirring stick
- Measuring cup to maintain consistent ratios
- Natural bristle brush or masonry brush for working paint into mortar joints
- Lint free rags or cotton cloths for blotting and creating texture
- Drop cloths to protect floors and surrounding surfaces
- Painter tape for masking adjacent walls, hearths, and trim
- Protective gloves and safety glasses
Optional Tools for Better Results
- Spray bottle filled with water to mist the brick before application for a more translucent finish
- Shop vacuum with brush attachment for cleaning dust out of mortar joints
- Trisodium phosphate cleaner if the brick has grease, soot, or heavy grime
- Sealer if you plan to use the whitewashed surface in a high touch area
How to Whitewash Brick: Step by Step Process
Follow these steps in order for the best results. Rushing the preparation stage is the most common mistake beginners make, so take your time with cleaning and testing.
Step 1: Clean the Brick Surface Thoroughly
Dirt, dust, soot, and grease prevent whitewash from bonding to the brick. Use a stiff bristle brush and warm water to scrub the entire surface. For fireplace brick, pay extra attention to areas near the firebox where creosote and smoke residue accumulate. If the brick is heavily soiled, mix a solution of trisodium phosphate according to the manufacturer instructions and scrub the surface. Rinse thoroughly with clean water and allow the brick to dry for at least 24 hours. Whitewash applied to damp brick will blush, streak, and fail to adhere properly.
Step 2: Mix the Whitewash Solution
The standard ratio for latex whitewash is one part water to one part paint. This 1:1 mix produces a semi transparent finish that covers well while still letting the brick texture show through. For a more translucent, subtle wash, use two parts water to one part paint. For heavier coverage that approaches a solid look, use three parts paint to one part water. Always mix thoroughly and test the consistency on a scrap piece of brick or cardboard before committing to the full wall.
Step 3: Apply the Whitewash
Work in small sections of roughly 3 feet by 3 feet. Dip the brush into the whitewash mixture, tap off the excess, and apply the mixture to the brick using a combination of dabbing and brushing motions. Focus on working the liquid into the mortar joints, because bare mortar stands out against whitewashed brick. After covering a section, immediately blot the surface with a clean rag to remove excess liquid and create a soft, variegated texture. The blotting step is what gives whitewash its characteristic aged look rather than a flat painted appearance.
Working Around Mortar Joints
Mortar joints absorb whitewash differently than the brick faces. If the mortar is lighter than the brick, it may end up too bright after whitewashing. Use a smaller stiff brush to apply the mixture specifically to the mortar, then immediately blot with a rag to tone down the brightness. Alternatively, you can apply a second light coat only to the brick faces after the first coat dries, skipping the mortar entirely.
Layering for Depth
Two thin coats almost always look better than one thick coat. The first coat provides the base translucency, and the second coat builds depth and evens out patchy areas. Allow the first coat to dry for at least two hours before applying the second. For an authentic weathered appearance, vary the pressure and paint density between coats so that some bricks end up slightly whiter than others.
Step 4: Seal the Whitewashed Brick (Optional)
Sealing is unnecessary for most interior brick walls because the whitewash itself is durable enough for occasional contact. However, if you are whitewashing a fireplace surround that may get bumped by fireplace tools or a kitchen backsplash area that could encounter grease splatter, a clear matte sealer adds protection without altering the finish. Use a water based matte sealer applied with a sprayer or a lint free cloth. Avoid glossy sealers, which ruin the chalky aesthetic that whitewashing is meant to create.
Common Mistakes and How to Avoid Them
Even experienced DIYers make errors on their first whitewash project. Knowing what can go wrong helps you prevent problems before they start.
Mistake 1: Skipping the Cleaning Step
Dirty brick is the number one cause of whitewash failure. The mixture cannot bond to oily or dusty surfaces, and the result is a patchy finish that flakes off within weeks. Take the time to scrub, rinse, and dry thoroughly. If you are working on an exterior brick wall, a pressure washer on a low setting works well for cleaning. Allow three full days of dry weather before applying whitewash outdoors.
Mistake 2: Using the Wrong Paint Sheen
Flat or matte paint is essential for whitewashing. Eggshell, satin, or semigloss paints contain binders that create a slight sheen, which looks unnatural when thinned with water. These sheens also form a more continuous film that reduces the breathability of the finish. Stick with flat paint in the whitest shade that complements your room. If you want a warmer white, look for paints labeled warm white or creamy white rather than adding pigment to the mix.
Mistake 3: Applying Too Much Whitewash at Once
It is tempting to load the brush heavily and cover large areas quickly, but this leads to drips, pooling, and an uneven finish. Work in small sections and blot each section immediately after applying the whitewash. The blotting step is not optional. It removes the excess that would otherwise dry into hard edges and visible lap marks. For an even more controlled application, try using a spray bottle to mist the brick lightly before applying the whitewash, which helps the mixture spread more evenly.
When to Call a Professional
While whitewashing is a beginner friendly project, some situations warrant professional help. If your brick has significant efflorescence (white powdery salt deposits), structural cracks, or signs of water damage, address those issues before applying any finish. A mason can repoint damaged mortar joints and waterproof the wall. For masonry repair guidance, see how to repoint brick steps restoring crumbling mortar joints to understand the prep work involved in getting damaged brick surfaces ready for finishing.
Maintenance and Long Term Care
A whitewashed brick wall requires very little maintenance. Occasional dusting with a soft brush attachment on your vacuum cleaner keeps the surface fresh. If the whitewash becomes marked or stained, spot clean with a damp cloth and mild soap. Avoid abrasive scrubbers that could scratch the finish. Over years of exposure to sunlight, the whitewash may yellow slightly. A fresh coat applied every five to seven years restores the original brightness. Because whitewash is thin, you can apply new coats directly over old ones without stripping, making upkeep straightforward compared to painted brick.
Whitewashing brick is one of the most satisfying DIY projects a homeowner can tackle. The materials are inexpensive, the technique is forgiving, and the transformation is dramatic. By preparing the surface properly, mixing the right ratio, and taking your time with application and blotting, you can achieve a professional quality finish that looks like it has been in place for decades.
