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 ...
The moisture control also helps protect natural materials such as wood used in the construction from getting damp and rotting. It's mould resistant - Due to the High PH of lime products (12-13), they are a natural biocide, which means they do not promote the growth of mould.
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.
Because limewash is nearly 10x darker when it is wet, it's important to test the color and let it completely dry. The color also changes depending on the number of coats applied and porosity of the surface being painted. That said, Romabio's Classico Limewash is a one coat finish that looks breathtaking!
Unlike artificial paints, Limewash will not need to be removed and only retouched every five to seven years. Most Suitable for Masonry Surfaces: Old buildings with masonry surfaces like stone, concrete, and brick are perfect fits for lime wash coating.
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.
One of the biggest cons of limewash is that it can erode over time, especially if exposed to harsh weather conditions. This means it may require more frequent maintenance than other paint or finishes. You may need to reapply external limewash every two to seven years to keep your walls looking their best.
The alkalinity deters wood-boring beetles and helps sterilise walls. Furthermore, limewash is inexpensive and solvent-free. The disadvantages are that much care is needed for the best results, matching coloured limewash batches is difficult, and limewashing is less successful in very fast-drying conditions.
Is limewash waterproof? While not naturally completely waterproof, a lime sealant can be applied over a limewash finish for additional water resistance and to make the lime walls easily wipable.
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 ...
However, if you don't want it to wash off, or if you're using it inside, you'll definitely need to apply a sealant. One way to make limewash and lime paint more waterproof is with a very small amount of linseed oil — no more than 1%.
Rubbing off: Limewash can sometimes rub off if applied incorrectly or if the surface wasn't properly prepared. Limitations: Using limewash with no additives limits its use to porous materials. It is possible to use natural additives such as casein to expand the range of surfaces limewash can be used on.
Remember that limewash will weather and patina over time, creating a beautiful aged look. So while it may not wash off in the rain, it will likely wear away gradually over the years. A touch-up or a new coat every three to seven years is recommended.
As it dries, the applied limewash gets lighter and much more opaque. The slower limewash cures, the more durable the result will be.
Whitewash is a type of paint or coating made from a mixture of lime, water, and chalk. It has been used for centuries as an inexpensive way to protect walls and other surfaces from the elements due to its high alkalinity, preventing mold growth on porous substrates like brick or stone.
Lime-Based Paints:
As mentioned earlier, lime-based paints have a high pH level, making them naturally mould-resistant. Their breathability also allows moisture to escape, reducing the chances of damp conditions that promote mould growth.
Finished limewash will gradually erode, which can produce a very attractive weathered look, but to retain the original opaque coverage, reapply the limewash every five to seven years. There is no need to remove existing limewash in order to apply renewal coats.
'Can I use limewash in a bathroom? ' is one of the most common questions we get asked. The short answer is—yes, you can paint your bathroom with Bauwerk limewash. Our paint is not just suitable for high-humidity environments, it thrives in these demanding conditions.
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.
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.
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 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.

Each coat should be allowed to dry before the next coat is applied. 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.
