I’ve been wanting to try one of these for a while now, ever since I saw (sorry, couldn’t escape that pun if I’d tried) something similar on Pinterest. So as I had an old saw and some spare time I did just that!
All you need to do, to do the same is, find an old saw (don’t use a good one as the paint won’t stick very well to shiny steel), rub down the rust and prime it with a shellac based primer, or metal primer. Then coat it with blackboard paint (matt black), let it dry and sign write it! You will probably want to stick to all the same type of paint, i.e. all oil based or all acrylic. Acrylic on oil doesn’t seem to work very well. I used acrylic household paints because… well, I had them in the shed.
This is the result. The verse is part of a Gungor song, “You make beautiful things, make beautiful things out of dust, You make beautiful things, make beautiful things out of us”. Perhaps even retired tools can be useful in the right hands.
