Color wash is usually prepared by adding an appropriate amount of colored pigment to a liquid mixture of screened white wash or white wash. It should be ensured that the pigment is not affected by the presence of lime. A color wash is applied in exactly the same way as a white wash. During its application, the color is constantly stirred with a stick. A quantity of color wash, sufficient only for the day’s work, should be prepared at one time in the morning.
Typically, ceilings are whitewashed and walls are colorwashed.
Before applying color wash to new surfaces or scratched surfaces, a coat of white wash should be applied. This coat will act as a priming coat and incidentally will also result in economy.
In the case of older work, a coat of color wash is first applied to spots or repaired work and surface blemishes. Two or more coats of paint are then applied over the entire surface until it provides the desired finish.
A satisfactory finish should not leave a powder when rubbed with the fingers.
