Pure ingredients for purists. It is as simple as milk, vinegar, lime powder, pigments and water.
Milk paint goes directly into your wood and is absorbed. That is why it is so durable as it does not create a top coating but rather is becomes part of the wood like stain.
The first coat of milk paint can be applied thin. If your base is too absorbent, the first coat can be diluted 20 to 50% with water as a priming coat. Lime is used The lime together with the Ocher or pigment, serves as fine aggregate filler in the paint giving it opacity. Other fillers can be used but settling becomes a problem and may add to a streaking look. Chalk or clay are common. Once dry Milk paint can be deppened with an added color glaze wax or other top coat. It provides a beautiful base to work with.
Spraying Milk Paint - Pure Milk paints and modern alternatives.
Pure Milk paint can be as thick as latex or thinner depending on how you thin it. It becomes more opaque as you thin so most people prefer to apply it thicker. We therefore recommend our latex setups to you. If however, you wish to spray thinner or have a more opaque color finish then a smaller nozzle can be used. We would not go lower than 1.8mm in a gravity feed or 1.3 in a pressure setup or 1.9 in a suction setup.
Powdered milk paint thats mixed with water is difficult to spray for a few reasons.
1) thickness 2) separation 3) lime interacts with aluminum
So we counteract these with the proper setup. Larger orifices, adjitation and all stainless steel.
Here are our suggestions: We have others if interested please email us.
Alternatively you can use a synthetic subsitutes like General Finishes. The pigment will be more stable and finer and will not spoil quickly like milk paint does. It also does not contain lime which reacts with aluminum and non-stainless parts. Also you can go with traditional Pigmented lacquer and even waterbased pigmented lacquer by Crystalac or Target Coatings or ML Campbell. These are thinner products and require a small orifice size
1.8, 2.0 Gravity is a good setup for Synthetic Milk Paint/ The 1.8 can double duty for pigmented lacquers or Urethanes.
We Suggest This Waterbase/Solvent based compatible Gun. One of the Finest guns with the lowest overspray levels.
