Spray painting plastic containers

For the hydroponics stuff I'm building, I needed to spray some plastic totes. This is so that they don't let any light in that can promote algae growth. Chalkboard spray paint was recommended so that's what I got.

It was only when I got home that I read on the can that plastic needs a primer to go on first. It looked good after spraying it without primer, but you have to handle it very carefully afterwards, otherwise the paint will just crack off.

I also learned that you need to spray from a distance of around 30 cm, otherwise the paint job will look blotchy and very uneven. So there you have it – two tips if you ever need to spray paint plastic containers.
