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. For best results, apply limewash in thin coats using an absorbent bristle brush.
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.
Lime works by reacting with soil particles to raise pH levels. However, when there is excessive rainfall, the lime can be quickly diluted and washed away from the soil surface before it has a chance to interact with the soil. This can result in uneven distribution and reduced effectiveness of the lime application.

If the paint has fully dried and you want to fully remove it or change the look, use a pressure washer to remove the paint. If you are not happy with how much you wash off, it is easy to reapply and touch up at any time as the paint finish is very flat. If it is difficult to remove, use a diluted muriatic acid mixture.
Wet the surface thoroughly before you start, to minimize the penetration of the product into the brickwork. If you use the pressure washer to do this, it will blow off any loose areas of limewash at the same time.

Areas like chimneys and exposed walls will wear down more quickly, but areas under cover, such as soffits etc. remain as you painted them for many years. “If you are open to limewash aging, then it's a finish for decades.
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.
