Matte Lime Wash Sealer is a 100% matte acrylic sealer that leaves a clear finish, is non-yellowing, and provides a protective topcoat with excellent clarity and extremely low sheen. The Lime Paint sealer is water-based and resists water, abrasion, household grime, stains and is easy to apply by roller.
One or two coats of sealer are recommended depending on the area. Allow the sealer to dry completely in between coats. NOTE: Allow the final coat of Tadelakt, lime plaster or lime paint surfaces to dry/ cure at least for 2-3 days before applying the sealer on top.
To this basic limewash may be added binders such as raw linseed oil, which will help it to adhere by making it moisture-droplet resistant while remaining vapour permeable. In the event that tallow is to be added this can only be effectively included during the slaking process.
In summary, limewash should not be sealed as it is a naturally breathable material. Using sealant can lead to issues with trapped water, damp, mould and condensation. Limewash is an excellent choice for living rooms, bedrooms, kitchens, and bathrooms but should not be used in areas exposed to high moisture levels.
Sealer or No Sealer? Limewash Paint leaves a velvety suede- like finish and provides a beautiful low-maintenance color. It cures over time and can be touched up easily with leftover paint. We recommend leaving it natural and not sealing it unless you prefer a protective durable matte sealed finish.
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.
Good quality limewash applied properly to a suitable substrate should not rub off readily onto clothes. Reasons for poor adhesion can be preparation with ordinary bagged lime, coats being applied excessively thickly, inadequate dampening down before limewashing, or too rapid drying out.
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!
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.
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.
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.
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.
As it dries, the applied limewash gets lighter and much more opaque. The slower limewash cures, the more durable the result will be.
How long does Limewash last? Limewash and lime coatings can last many decades, but realistically if you have a limewash finish you might want to reapply every five to seven years for the best and most durable finish.
In our area, molasses and table salt were often used. Salt was often added to exterior limewash to make it more durable and dry slower, producing a better finish.
Ideally leave each coat to cure for 24 hours. For each further coat, follow the same procedure as the first coat. Protect external limewash from the weather if necessary.
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.
Once Limewash is fully dry it is more stubborn to remove, but scrubbing with a little vinegar does the trick.
Limewash is a very durable finish and can last for many years with proper care. It is best to reapply every three to five years to maintain the original look. To clean limewash, simply use a soft brush and mild soap. You can also pressure wash it if necessary.
Limewash is easy to apply with a large masonry brush, and it's opaque so you can control the depth of color with the number of layers of paint you choose to apply. In addition, limewash will fade over time, so it needs to be re-applied, but it won't chip and flake like paint.
The putty is aged and then thinned with water and colored with natural pigments. Limewash creates surfaces that are mottled and matte with a chalky texture something like suede. It lends a depth and luminosity to flat walls. Above: Limewash creates a textured, shadowy effect.
You can use an acrylic-based primer for this purpose. A good practice is to use an alkali-resistant primer. Once the walls are primed, you can start painting. You can use a roller or brush to apply the new paint.
Step 2: If you are working with a nonporous, previously painted, or water repellant surface, you need to apply a 100 percent acrylic primer as an undercoat to the limewash.
