This technique of setting up is very simple. It gives the decor a moire aspect that is enriched with original hues, according to taste.
Cost: € 5 per meter2
Time: 2 days for 10 m2
Supplies: satin acrylic paint (1 hue in jar, 1 tube hue), 1 sea sponge, a paint tray, 2 flat spalters 50 and 60.
The principle of this technique is to play on several superimposed keys to create a relief effect. We chose here to treat a white background on a wall that previously received a matte acrylic underlay (so-called printing). The painting is a yellow acrylic. The ranges proposed by the manufacturers (Astral, Tollens, Ripolin, Valentine...) are so extensive that it is easy to make a very personal choice.
Our example is based on a monochrome. The second color is obtained by shaping the base yellow with a tube of Sienna (Lefranc and Bourgeois, Pébéo...).
the support can be colored directly by tinting the preparatory impression and by associating the color or colors with the sponge.
A more daring variant is to choose very different colors between the bottom and the mouchetis: yellow / lees of wine, pistachio / parma or anise / raspberry...
To your sponges!
The patina sponge is done in two ways. The most common practice is that of the sponge "in positive" (applying paint), simpler than its variant "in negative" (by removing the paint) which requires more fingering.
When preparing the material, opt for a natural sponge. The household versions are too smooth and do not produce the desired effect.
Before you start, do not hesitate to get your hands on an attached surface or on sheets of cardboard!
1. Pour a small amount of acrylic paint into the tray. Dilute with 10% water (renewed if necessary). Moisten the sponge very lightly on its operational side.
2. The charge must be light. Gently dip the sponge into the tray and flick the paint. We can also spread the color on the striated part of the tray to take just a little.
3. Start from a high angle. Dab by turning your wrist from left to right to avoid any regularity. Book small areas of virgin paint. Let dry.
4. To darken the base color, add a small amount of darker paint. Be careful, the preparation must be sufficient to cover the entire wall. Mix thoroughly.
5. Apply the darker color to the remaining blank areas and the previous shade, but do not completely cover them for the desired moire effect. Let dry.
The application in negative
1. Dilute the paint with at least 50% water according to the desired effect and apply it to the spalter n° 50 on the wall in small areas of about 50 cm2it must not dry.
2. Lightly moisten the sponge and dab: the principle is to remove the paint in small areas. The gesture must be dry, without turning the wrist. Rinse the sponge very often.
3. Touch the part with a clean, dry spalter # 60 to blend and unify the shade. Provide plenty of clean rags to wipe the brush often, which should stay dry.
