GENERAL FINISHES MILK PAINT: Lamp Black

RECOMMENDED SPRAY GUNS:

In the shop, we use the 3M Model HG18. It comes with a large diameter fluid tip and a disposable air cap. This allows you to use it several times before replacing.

In this video, we use a self-contained system, the Earl-X 5500 HVLP System. It also comes with a large fluid tip designed for spraying paints.

SPRAYING TIPS:

  • If Milk Paint needs to be thinned: Use 10 percent water by volume, which is 3 fluid ounces per quart.
  • Keep the gun at a 90-degree angle. Overlap about 25 percent.
  • Work in manageable sections.
  • Use a respirator.
  • If you have never sprayed before, practice on a piece of paper or cardboard.
  • If you get a run or any kind of error or drip, take a brush and lightly brush it out.
  • Allow project to dry 1-2 hours. Sand topcoat smooth with a 220-grit sanding pad.
  • Repeat with 2-3 more coats until satisfied with the finish.
  • Milk paint dries to a low luster sheen and is durable to stand up to medium wear.
  • If more protection is required, apply 1-2 coats of General Finishes Water Based High Performance Topcoat for interior and General Finishes Exterior 450 Topcoat for outdoor applications.
  • Cure time is dependent upon temperature and humidity; at 70 degrees Fahrenheit and 70 percent relative humidity, 3-4 coats of Milk Paint will cure in about 14-21 days.
