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.

We recommend 2 coats of a good quality water based drywall sealer primer.
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.
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.
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.
We recommend 24 hours between coats. It is very important to rewet the previous coat before applying the next coat. At least 4 coats will be needed to cover new work.
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.
Apply Classico Limewash with the Romabio Large Masonry Brush or a standard paint sprayer. (Rollers are not recommended). One coat is needed to create an antique limewash effect. The paint is a very flat finish, so you can touch up at any time.
Erosion: Limewashing will erode over time, meaning it will need to be retouched every five to seven years. Not Applicable for Painted Brick: Since Limewash penetrates the brick, it can't do so if the surface has already been painted.
So, you can understand my delight when I came across a TikTok tutorial for DIY limewash effect walls that used regular water-based paint and claimed to cost less than $15! With my new bout of optimism, I decided to take to my bedroom walls to try out the trend. This is what I learned in the process.
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. The wider thicker ferrule allows for more bristles and allows for a greater painting efficiency, due to its greater capacity to carry the thin paint.
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.
As it dries, the applied limewash gets lighter and much more opaque. The slower limewash cures, the more durable the result will be.
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.
It is not fully opaque. Limewash can still be used on non-porous surfaces but you have to use a special primer. Lately, lime paint has been trendy for its soft velvety appearance that gives a wabi-sabi feel.
The key is to go with a mineral-based primer–such as an acrylic primer (used often under latex paints)–that creates a surface the limewash can bond to. Above: Limewashed walls and concrete floors pair well in this Daytrip Studio-designed sitting room.
Each person paints limewash paint slightly differently. After the first coat is dry and beginning to cure (overnight is best, but not required), apply a second coat. The second layer typically will use more limewash paint than the first layer, even as you spread the paint thinly over the surface.
You can lime wash unsealed and unpainted brick, slate, stone or any porous surface without any primer. If the interior or exterior surfaces have been sealed or painted you can use our Mineral Primer for Interior + Exterior to prime the surface and then lime wash it.
The only issue with limewash is that it doesn't work over latex paint, but it seemed like you could put down a primer to give the limewash something to adhere to. I ordered the limewash and primer along with a large brush recommended for applying.
In general, limewash may be made from lime putty or hydrated lime by the addition of water to make a slurry with the consistency of whole milk. In terms of solids (lime) content, this works out to be a mixture that is approximately 15 to 20% lime and 80 to 85% water (one gallon of water, at 20 °C weighs 8.33 lbs.).
Brush apply limewash with a large emulsion or masonry brush. Don't allow it to build up too thickly as it can craze on drying out. Remember it's a wash and will look transparent on application but will dry opaque. Coloured limewash dries to a much lighter shade than the wet colour.
Limewash paint does not need to be sealed, as it is a naturally breathable material. Sealing it can lead to issues with trapped water, damp, mould, and condensation. Limewash is an excellent choice for living rooms, bedrooms, kitchens, and bathrooms.
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.
