How to Spray Milk Paint

Today we’re going to show you how to spray General Finishes Milk Paint. We like a couple of guns for spray applications. The one we use in the shop is the 3M model HG18. It comes with a large diameter fluid tip for paints and a disposable air cap. That allows you to use it several times before replacing. But for our demo today, we are going to use a self contained unit. It’s the Earl-X 5500 HVLP Sysytem. Its comes with a large fluid tip designed for spraying paints. Any sprayer will work, but contact your local supplier to verify the proper tips sizes. Every gun is different. After stirring the Milk Paints, it’s ready to spray from the can. If you need to thin the paint, most people just use 10 percent water by volume. Which is 3 fluid ounces per quart. Let’s go outside and paint a table. Now we’re going to show you how to spray the Milk Paint. We have a little pine table here that our project and today we are going to spray the Lamp Black, a Real popular color. What I like about the gun is that is has the setting on the front. This determines how you spray your paint. The fan pattern changes by a click of the nozzle. And the fluids settings are in the back of the gun. I think its a good idea if you’ve never sprayed before. Practice on a piece of paper or cardboard to become more familiar with your gun, I’ll show you. Determine how much fluid you have coming out of you gun and which way your fan pattern’s going. Anytime the guns pointed this way, you can see I’m spraying vertical, or I can spray horizontal. Nice. A couple of key points to want to keep in mind here. When you’re spraying, keep your gun at a 90 degree angle. That puts a nice even uniform coat of finish. Overlap about 25 percent. All you want to do is make sure you’re coving all the dry spots. And work in managable sections. Today we’re going to start with the top and we’ll work our way around. So, let’s just go aead and I;ll show you how paint hte table here. I’m going to use a respirator, it’s a good idea. Alright. Just take a look and see how even and uniform that put that paint on top of the table. If you get a run, or anykind of error or drip, any kind of mut. Just take the brush and just lightly come back and brush out the paint. This is going to dry in 1-2 hours and when we’re done, we’ll take a look at the table and see how we did. Allow your project to dry for 1-2 hours. And then sand the top coat down smooth with a 220 sanding pad. Repeat this process with 2-3 more coats until you’re satisfied with the finish. The milk Paint dries to a low luster sheen and is durable enough to stand up medium wear. However, if more protection is required, apply 1-2 coats of High Performance Water Based Top Coat for interior use. Or Exterior 450 for use in outside applications. The cure time is dependent apon temperature and humidity. At 70 degrees Fahrenheit, 70 percent relative humidity, 3-4 coats of Milk Paint will cure in a bout 14-21 days.
