This is a super easy and thrifty way to age a plastic thrifted urn with craft paint.
Before starting to paint, cut up a plastic grocery bag and use as a drop cloth. I did a quick two coats of cheap (50 cents at Walmart) white craft paint.
When you paint something like this, make sure you paint down the inside an inch or two. You don’t want the original black plastic to show.
Once the paint has dried, I mixed the white craft paint and some black craft paint to get a gray I liked.
Next just start painting the gray over the top of the white. No need to be careful how it is painted. Just get the paint on. This picture is just to show that it doesn’t matter how “neat” the paint is. But, I recommend doing this in smaller portions because the paint dries fast and you want to rub it off with a soft rag.
This is the messy party! You are going to rub off as much or as little of the gray paint you want. There is no right or wrong way to do this. If you wipe too much off, you can do again and put more gray paint on. If it is too dark, add more white paint to it. You make it look the way it appeals to you!
Now grab some sandpaper and start going over the raised areas. Once again, like above, there is no wrong or right way. You chose how much distressing you want on your urn. Once you get the “look” right and are happy with it you can give it a quick clear coat spray or not. If it is going outside I would do a clear coat finish on it.
