Porter’s French Wash™ creates the look of delicate broken colour - a subtle marble-like finish. Step 1 is the application of Porter’s Low Sheen Acrylic, tinted to an appropriate colour and used as a base. Step 2 is the application and ragging of the French Wash™ (usually tinted slightly darker) over the top of the Low Sheen Acrylic, creating the soft, broken colour effect.

Do not apply paint if Relative Humidity is above 85% or temperature is within 3°C of Dew Point.
Do not apply if the surface temperature is greater than 30°C or below 10°C, or likely to fall below 10°C during the application or drying period.
All surfaces should be prepared with two coats of Porter’s Low Sheen or Porter’s Eggshell and allowed to dry for 18-24 hours before commencing with French Wash. Please refer to specification or on-pack details for Porter’s Low Sheen or Eggshell for information on surface preparation and application method.

Step 1 – application of Porter's Low Seen Acrylic:
Stir paint thoroughly prior to use. Apply two coats by brush, spray or a medium nap roller. Touch dry in 1 hour. Allow minimum 2 hours dry time between coats. Allow 18-24 hours dry time.
Step 2 – application of French Wash:
(For non-professional painters, the application of French Wash™ is a two-person operation).
Starting at the top left hand corner of the wall the first person should apply French Wash™ using a wide brush (50-75mm) in a random pattern. It is important that good coverage is achieved and there are no areas where the product is not completely applied. Following closely behind, the second person creates the desired pattern by ragging muslin cloth over the freshly painted French Wash™ surface, turning the cloth in your hand to avoid a “stamped” pattern and to use dry areas of cloth. The method we recommend is not to hold the muslin on the surface and roll, but to use a large amount (at least 5m) of scrunched muslin and “pounce” or press this quickly and repeatedly to the wall, absorbing the French Wash and leaving a broken, subtle pattern of colour. Care should be taken to leave a wet edge (at least 15cm wide) at all times. Do not go back over completed work. Do not stop in the middle of a wall. All work should be arranged to allow completion at a natural division such as a corner. Corners can be ragged by flicking the muslin into the corner.
Touch dry in 2 hours. Allow 6 hours dry time.
Please Note: Do not change roles during application as each person has an individual style or technique, and an inconsistent result will be very obvious on the wall.
If a second coat of French Wash™ is required (either in the same or a different colour), allow first coat 24 hours dry time.
Allow 72 hours dry time before applying any clear sealer (optional).
Additional application tips:
For a softer, more subtly aged look - just when the French Wash™ is nearly dry, use a dry flogger brush to lightly brush in all directions, breaking up darker areas and creating a very subtle colour variation.
For a more complex colour layered effect – multiple coats of French Wash™ in varying colours can be added, as long as the previous coat is completely dry.
Use the wall as your palette – use 2 or 3 French Wash™ colours at once, blending areas as you go.
