The prepared putty should be completely homogeneous (without chalk interlayers additionally drying oil), should not stick to hands either to the knife, and on a cut to own a smooth bright surface.

During the preparation, putty can be tinted in the desired paint. For this purpose it is necessary to add a white or other paint to mix additionally up to a working consistence. If dry paints are added to the putty, they are best mixed with chalk, but densely packed with linseed oil. If the putty has turned liquid, it should be added a little chalk, if thick - drying oil, but then change hands.
