STEP 4: Mix Limewash with water Limewash is a concentrate and is usually thinned with clean water before use. Generally thin the first coat with 50% water. The first coat provides a uniform finish that completely covers the primed or bare masonry surface.
It is an alkaline liquid with a very high Ph-Level. So if you left the paint uncovered by accident and see the liquid content reduced you may add a maximum of 10% of water. Any more and the carefully balanced paint materials will no longer be performing as intended.
Lime Wash Myth #12: Limewash looks different when it is wet. Romabio Answer: True. If you apply an authentic slaked-lime paint like Classico Limewash on brick and stone and it rains, the lime wash will appear translucent or slightly different.
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.
The decision to seal limewash ultimately depends on your specific needs and preferences. Sealing can provide an additional level of protection, making the surface wipeable and slightly more resistant to staining. However, there are some factors to consider. Firstly, adding a sealer may increase the sheen of the finish.
There are also 3 limitations and disadvantages of the lime-wash: The very rigid demands to weather, temperature and moisture-conditions during the application, the strict demands to experienced craftsmanship and the demands to a perfect, un-defect, dry and "cement-less" ground.
Powdering usually occurs when limewash paint is applied too thickly, preventing it from curing properly. This causes the lime to 'bloom' on the surface, leaving white patches and making it powdery, so it comes off easily when touched.
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.).
-Rain and water exposure plays the biggest role in the weathering and aging process. If you want to reduce this effect and keep Classico Limewash lasting longer, we recommend adding Mineral Shield, an invisible, environmentally friendly topcoat that repels water to protect your finish.
There is no limit to how many layers you apply, simply keep working until you develop the look you desire.

Use a paint brush to cut-in the edges of your wall, around trim, windows, doors, etc.
What is important to know is that for a nice lime wash finish the lime paint requires an evenly absorbing surface with not too much and not too little suction. Repairs or crack filers can detract from a beautiful lime wash finish if not properly primed / sealer and undercoated.
Dilute The Paint With Water.
Unlike other paints, you must dilute Classico Limewash paint with 100% water or 1:1 which is 1 part paint to 1 part water. For 1 quart, add 1 quart of water, and for 4 gal., add 4 gal. of water. Pour the paint into a large mixing bucket, then add the appropriate amount of water.
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.
When you water down exterior paint, it changes the color by making it lighter.
You are able to dilute the lime paint to the level of wash you desire. It puts you in control of the finish you want to create. Many clients put the first coat on full strength and then add some layers of lime wash by diluting 1:1/2 (one part paint to 1/2 part water) or 1:1 (one part paint to 1 part water).
Q. How do I fix my limewashed wall that has white powdery patches or spots? Fix 1. To cover white patches from over-application, simply wait 24 hours and apply an additional thin coat of limewash paint.

BAUWERK Limewash Paint is not a water-proofing material, it is water resistant. The ideal surface to apply the paint is a mineral based absorbent render (or similar).
Lime (calcium oxide) is a white solid with strongly basic properties. Lime reacts readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction.
