How to Whitewash or Limewash a Brick Wall: A DIY Guide for Homeowners
Transform your brick walls with these traditional techniques that add character and charm to any space. Learn the difference between whitewash and limewash and how to apply them like a pro.
Got a brick wall that's looking a bit tired or dated? Whitewashing or limewashing could be the perfect solution to give it new life. These traditional techniques create that beautiful, weathered look you see in heritage homes and modern farmhouses alike. Best of all, they're surprisingly DIY-friendly!
What's the Difference Between Whitewash and Limewash?
Think of whitewash and limewash like cousins - similar but with their own personalities:
- Whitewash uses diluted latex paint for a more modern, opaque finish
- Limewash uses slaked lime (calcium hydroxide) for a traditional, breathable finish that lets the brick texture show through
Limewash is the original method used for centuries, while whitewash offers more control over the final look. Both create that beautiful, aged appearance that makes brick walls so charming.
Gather Your Supplies
Before you start, make sure you've got everything you need:
- For whitewash: White latex paint, water, mixing bucket, paint brushes or roller, rags, drop cloths, painter's tape
- For limewash: Hydrated lime, salt (optional), water, large bucket, masonry brush, safety gear (gloves, goggles, mask)
Remember - lime is caustic, so always wear proper protection when working with it!
Step-by-Step Application Guide
Preparation is Key
Start with a clean surface. Brush away any dust, dirt, or loose mortar. If you're working on an exterior wall, you might want to give it a quick power wash and let it dry completely.
Protect your surroundings by masking windows, trim, and doors with painter's tape. Lay down drop cloths to catch any drips - this stuff can get messy!
Mixing Your Wash
For whitewash: Mix equal parts latex paint and water until you get a smooth, milky consistency. Think of it like making a thinned-out paint soup.
For limewash: Combine 25 lbs of hydrated lime with 4 lbs of salt (optional) and enough water to reach a pancake batter consistency. Let it sit for at least 3 hours to activate - patience pays off here!
Application Techniques
Work in small sections, especially with limewash. For limewash, lightly dampen the brick first to help it absorb evenly.
Apply with a brush or roller, using a rag to blot and create texture as you go. Don't try to cover every nook and cranny - part of the charm is letting the brick texture show through.
With whitewash, you can build up layers for more opacity. With limewash, work quickly within 30-minute windows to ensure even colour.
Pro Tips for Success
- Always test your mixture on a small, inconspicuous area first
- Wear old clothes - this can get messy
- Vary your application pressure for a more natural, textured look
- Let the first coat dry completely before deciding if you need another
- Both methods are forgiving and easy to touch up if needed
Final Takeaway
Whitewashing or limewashing a brick wall is one of those satisfying DIY projects that can completely transform a space. Whether you choose the modern simplicity of whitewash or the traditional charm of limewash, you're giving your brick character and personality.
The beauty of these techniques is their forgiving nature - if you don't love the first attempt, you can always adjust or add another coat. So grab your brushes and get ready to create that beautiful, weathered look that makes brick walls so special!
