Fake Plastic Grids

Having used the white silicone that I had around the house to create a few samples grids., I then went about experimenting with painting them. One I sprayed black, but the paint, once dried, flaked off easily. On the next I tired using a primer, which was more hard wearing than the black paint, but once I sprayed the black onto, it became flaky again. I like how the paints flaked, it was really interesting but it doesn’t half make a mess.
