To achieve the desired result, it is better not to burn the stages of the combed patina: a thickened paint then patinated by an almost transparent glaze. Finally, your brushstroke changes everything!
Cost: about 8 € per m2
Time: 3 to 4 days
Supplies: matt acrylic paint (white), dye (matte acrylic paint), satin acrylic lacquer, Meudon white, sander and fine abrasive, paint tray and whisk, 2 flat spalters no. 70 and 100 preferably notched.
The effect of material is due to the addition of fine fillers ("Blanc de Meudon" Liberon, The Nordin Brothers) which thickens the paint and allows to play according to his tastes: the application tool, roller or brush makes the difference.
To get started, customize the background color and save the purchase of a tinted paint: add a universal colorant of your choice to the white acrylic paint (which you will use for the glaze). The result is always pastel, it is quite suitable for this type of decor.
Combined patina: play transparency!
The final touch (second layer) enhances the combed appearance of this patina by the use of a satin acrylic glue that "hangs" the light (Duralex, "Polydeco" Tollens...).
The glaze obtained by mixing it with white acrylic paint is almost transparent and makes the wall leachable (a non-negligible detail).
More or less pulled to the spalter to mark the irregularities, then slightly sanded, it gives to this decoration all its softness.
The patina combed step-by-step
- Pour into the bin the amount of colored paint needed to cover the entire wall and add 40% of its weight of "Meudon white".
- No need to dilute with water!
- Add 15% of its total weight of glue to the unmixed mix.
- Mix with a paintbrush to obtain a light and perfectly smooth paste, without any lumps.
- Apply this mixture to the wool roll all over the surface.
- No need to pull it or make a regular application.
- Allow to dry completely, at least 12 hours.
- To prepare the patina (second coat), dilute the amount of white paint needed with 30% water.
- Then add 30% of its weight in glue.
- Mix thoroughly.
- Apply this glaze from top to bottom using the # 100 spalter.
- Proceed in small areas of irregular thickness.
- Pull vertically with a second spalter wiped on a dry cloth.
- After complete drying for at least 24 hours, sand lightly with a fine-grained abrasive (150) to bring out the hue and highlight the combed effect.
Variations of patina effects
- To obtain more thickness (the effect of material will be more pronounced), apply the thickened mixture to the spalter without pulling it by creating marked stripes in the direction of the height.
Here are the effects obtained depending on the tool used.
- On the left the result produced by the passage of the roll.
- On the right, the one obtained by the spalter enhances the background.
Pro tips for patina
The "White of Meudon" can be replaced by smoothing plaster (Toupret, Bostik...) which contains plaster and glue. It is then added to the paint to the extent of 5 to 20% of its volume according to the desired thickness. Make sure the stripes are vertical: the notched spalter makes it easy for you, help yourself with a plumb bob!
