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.
Often when applying Lime Paint the surface texture may be rough, such as that of a brick, stone or stucco. 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.
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.

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.
The common reasons for limewash rubbing off are a bad application technique, poor quality limewash, and drying too quickly. It is essential to ensure that the surface is prepared correctly, with adequate moisture control and proper drying and carbonation processes.
Overly heavy coats will craze and crack when they harden and dry. If this occurs, wash off with hot water and a stiff brush and ensure that the new covering is properly applied. Containers of lime wash should be constantly stirred during application to ensure even distribution of lime and pigment.
