Sponging paint on the wall is one of the simplest techniques to use when it comes to faux painting. It involves the application of various paints onto the walls with a soft sponge, dabbing over and over until the entire wall is covered. The more colors you use, the greater the illusion of depth and texture.
Faux Venetian plaster imitates the look of an old plastered wall. It is achieved by applying layers of undiluted paint with a trowel. It gives a textured look that is still smooth to the touch. It is best applied to a smooth flat surface to avoid damage to the walls due to the use of the trowel. Use four different paint colors for the best effect. Work while the paint is still wet for an easier application.
Craquelure is the look of furniture and walls that appears quite aged and cracked. The paint appears to have cracked and may, in fact, be falling off. As strange as it may sound, this effect is actually quite lovely when used as a faux technique. Water-based crackle varnishes are used to achieve this effect and are preferable to oil-based material, as they have less odor and work through the process of evaporation. Water-based crackle varnish can be tinted to suit your decor. Consult a paint professional for complete application procedures.
