Tom Monahan of General Finishes uses the the spray application to apply General Finishes Milk Paint for an even coat and fast application!
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 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 HP Water Based Topcoat for interior and Exterior 450 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 21 days.
Thinning: Thin GF water based products with 10-15% extender or water at point of use only. Decant what you need into a separate container and use immediately. If thinned water based products are stored, they will separate and lose the semi-gel consistency.
