Limewash and whitewash often appear together in a quick search when looking for ways to paint brick—so, what’s the difference? Limewash paint is one of the most natural and environmentally friendly ways to paint brick. It’s made from limestone and water, giving it an off-white appearance that looks similar to whitewash. However, limewash is semi-permanent, whereas whitewash is a more permanent, watered-down version of existing paint. 

Both brick paint options are economical and light in color, but if you want to change the appearance of your home’s brick in the future, then limewash might be a better option.

Limewash and whitewash do not harm surfaces if you apply them correctly. Use on non-suitable surfaces can cause issues. For instance, applying limewash or whitewash to surfaces with existing sealants or incompatible materials may lead to poor adhesion or flaking. Also, harsh cleaning agents on limewashed or whitewashed surfaces can damage the finish. Proper preparation, application, and maintenance ensure that limewash and whitewash do not harm surfaces.

If you’re deciding between limewash versus whitewash, know that both have a chalky matte appearance. Limewash is made from lime, water, and sometimes pigment, while whitewash consists of lime, water, white chalk, and binders (though you can get a similar look with watered-down white paint). Whitewash has fewer options for color customization, and it sits on surfaces instead of being absorbed into them, which can trap moisture. Whitewashing costs less—about $1.40 to $4.20 per square foot.

If you want to avoid damaging your home's brick, you should always use a stain specifically formulated for masonry projects. These stains are designed to penetrate the porous surface of the brick and bond with it, unlike paints, which sit on the surface and are prone to peeling and flaking. Look for stains labeled for use on brick or other masonry surfaces. Avoid using regular paint on brick, as it will not adhere well and will likely lead to future maintenance issues.
