I have a kitchen table that was finished with milk paint and needs a touch up. How do I make milk paint?
Here's a recipe from Martha Stewart

If you're just touching it up, you might want to use the same brand and color that was first used.
Touching up requires a good match. Repainting the entire surface usually looks better. I prefer the look of premade powders that you mix or premixed milk paint from the handmade milk paint I've used.
