Walls need not be so well prepared for this technique, which can be so informal that damage to plaster becomes part of its character. Lining the wall is therefore optional. Paint two coats of eggshell paint on the surface that is to be color washed. Wait until the second coat is dry. Then mix the glaze to the required consistency and color, testing it first on an area that will not be seen.
Technique
Color washing is a relaxed, haphazard technique of making freehand brush strokes across the wall to cover it. These can be short and sharp if you like, or long and curved like grasses, going up and almost swaying over the wall in long vertical sweeps. A larger brush – even a wallpaper brush -is generally used to get the soft lines and easy grace of the color washed mark.
Depending on the color intensity and the effect you choose to create, you can paint with the glaze directly on to the wall, making whatever brush mark pattern appeals to you. Alternatively, for a more transparent effect roll on the glaze with a throw-away sponge roller and then take it off with a dry brush, using the same technique as dragging but with much more carefree brush strokes. Practise first, and you may find that painting the glaze directly suits the color and style you have chosen. It is a good idea to paint a 60 cm (2ft) square of hardboard when you apply the eggshell to the surface being treated. This becomes your test panel on which to try out colors, combinations and brush strokes before you start.
1. Pour glaze into the paint tray and roll a strip about 2 m (6 ft) wide. Do not do much more than this, as the leading edge needs to stay wet ready for the next coat to merge well.
2. Starting at one side, work up and across the wall. Using a brush or cloth, make sweeping marks up and down or criss-crossed over the glaze. Work the whole strip to within 12 cm (5 in) of the leading edge.
3. Roller another strip of glaze, working out from the still wet first strip so there are no definite lines or overlaps. You will get into a rhythm and find a natural pattern as you work.
4. Color wash the second strip working out from the first strip so that the patterning continues in the same fashion. Avoid overworking a particular area or too much glaze will come off and leave a pale patch. Also avoid repairing small areas – it is usually better to wipe it clean and start again.
Keeping the Brush Clear
As soon as the brush or cloth gets too dense with glaze, wipe it dry on a rag or piece of kitchen paper. Change cloths or wipe the brush frequently. However, these requirements are less crucial in color washing than in other glaze techniques because an uneven, haphazard effect is characteristic of the style.
Applying Glaze Direct
If you are applying the glaze directly to the wall you can miss out steps 1-4 and make the brush strokes straight on to the surface. You will invariably use more glaze this way and get a more intense color.
