Drywall: If you are painting new or previously painted drywall you MUST apply a mineral primer to provide a porous base for the Limewash. Use Keim Interior Mineral Primer, which covers about 300 square feet per gallon. Apply primer by brush or roller and let dry 4 hours or overnight.
Prep by cleaning the brick or stone and cover any areas that will not be painted. Dampen the surface with water allowing Classico Limewash to slowly absorb without drying too quickly. The wall should be wet, but not dripping. Exterior: Use a typical garden hose spray nozzle or a pressure washer.
White Base Primer is the best option for most applications. Clear Base Primer allows the natural color of your substrate material to show through. We recommend one coat of Lime-Prep primer and two coats of limewash paint for most applications.

We recommend 2 coats of a good quality water based drywall sealer primer.
Whether you're using it indoors on walls or ceilings, a mineral primer is necessary for the limewash to adhere to non-absorbent surfaces. “A more traditional surface, such as plaster and absorbent masonry surfaces, will not require a mineral primer application,” Dunn says.
Generally limewash should be applied thinly and be allowed to dry out slowly. Our limewash is prepared from the finest quality lime putty slaked from quicklime. It will develop a fine finish over several coats; we recommend a minimum of 3-4 coats on new render and plaster.
Limewash paints can be used on a variety of surfaces. Each formulation is a little different so be sure to check with your paint's manufacturer. As a general rule, lime paints can be used on any porous masonry or concrete. They can be used over previously painted surfaces as long as you use a primer first.
Previously painted surfaces should be primed first for best results. Limewash can be applied on smooth or textured walls, but we decided it was worth it to skim coat our textured walls first to create a smooth and even canvas.
If you apply Classico Limewash paint that day and it dries for 3 – 4 hours, normal rainstorms should not affect your paint finish. In fact, Classico Limewash paint is an authentic slaked-lime paint that will continue to get harder over time as it gets wet and dries.
Preparing for Lime-Washing
Before starting the lime-washing process, ensure your solid wood floors are thoroughly clean and free of dust, dirt, and grime. If your floors have a previous finish, you'll need to sand them down. This ensures the limewash adheres properly.
Often when applying Lime Paint the surface texture may be rough, such as that of a brick, stone or stucco. A good brush for Lime Paint should be made of a high quality, durable natural bristle. What would be the most distinctive difference is the size.
And though limewash is bacteria- and mold-resistant, thanks to the high pH level of the lime, Helene van Os, brand manager for Pure and Original, says, "If you're going to use limewash paint in a humid or high-trafficked area, make sure you protect it with a sealer, as lime is porous and more vulnerable to dirt and ...
As it dries, the applied limewash gets lighter and much more opaque. The slower limewash cures, the more durable the result will be.
A pro of limewash is that it will not peel off like normal paint since it penetrates the brick. This means less maintenance than painted brick. It also lets the brick breathe. And speaking of less maintenance, since limewashed brick creates a worn and weathered look, natural wearing and aging will be less noticeable.
Although many people love limewash paint, it does create a mottled look that is hard to control and may not be for everyone. Some projects may require several coats of paint to achieve the desired effect. In addition, the high pH means the paint can irritate skin and must be handled carefully.
Low-Maintenance: Limewash is also considered a low maintenance brick makeover solution. Unlike artificial paints, Limewash will not need to be removed and only retouched every five to seven years.
It penetrates the surface of your wall, creating a mottled matte appearance with variegated colors (resembling the look of a plastered wall). This DIY version has the same effect, but involves thinning paint by mixing it with water, then applying it to the wall in circular motions using a cloth instead of a brush.
Limewash pigments come in a variety of organic colors. The colors we use most often are earthy neutrals like white, taupe, grey and charcoal. Of course, when looking to make a statement, colors like emerald, cobalt, black, terracotta or blush are perfect choice.
It can be hard to get the limewash to blend with water if you're mixing by hand. It costs more than paint. It isn't as long-lasting as whitewash – while it won't flake like paint, it still needs touch-ups regularly, and usually has to be redone every 5-7 years.
Stir Lime Wash thoroughly before and during use. Check color on a small inconspicuous area before proceeding with entire job. Lime Wash should not be applied below 55 degrees Fahrenheit, or in direct sun or extreme heat. Complete the painting of all adjacent surfaces, e.g. joinery, prior to application.
There are also other natural benefits to limewash paint: It's breathable, nontoxic, and eco-friendly, and the high pH level means that it's bacteria- and mold-resistant. Also, because limewash paint contains no VOCs (volatile organic compounds), its application is practically odorless.
Salt was often added to exterior limewash to make it more durable and dry slower, producing a better finish. Salt probably came from local salt works. Limewash could also be colored if the opaque white lime color was not desirable.
Limewash is typically cheaper than paint because it is less labor intensive and requires fewer materials. However, the cost will vary depending on the size of your project and the type of brick you have. If you are considering painting your brick, be sure to get an estimate from a professional first.
