Making fiberglass roofing look rusty

DIY rust effect.

Welcome back to my new escape room build: The Bayou: Legend of the Midnight Raven.

Today we are going to look at how to make something look rusty. In this instance I needed some corrugated tin roofing, like something you might find on an old shack out in the swamps.  Of course since it IS in the swamps it’s going to be all rusty.  I also didn’t want to use real metal roofing so I opted to purchase a fiberglass roofing that was a sort of smokey gray color.

You’ll want to use at least 2 colors of paint. I used a dark, red color and a dark brown color.  Start with the red and just dab it all over the roofing, or whatever it is you are going to rust. You don’t need a lot of paint. It should not be enough that it runs so you’ll wipe the brush off pretty good before dabbing.

When you are done immediately do the same thing with your second color. You don’t want it to dry.

Next you’ll want to get a big container of cinnamon. Yup! Just plain old, ground cinnamon.

You are going to want to sprinkle the cinnamon all over the painted areas while they are still wet. Don’t be afraid to use a good amount of the stuff.

Now wait for everything to dry.  I was doing this outside on a hot day and it was dry within an hour or so. Again, mostly because we didn’t use a thick, heavy coat of paint so it should dry pretty quickly.

Once it’s dry, take a brush and brush off all the excess cinnamon. You’ll want a relatively soft brush so it doesn’t just rip it all off.

Give the paint some time to dry and then brush off the excess cinnamon.

Now at this point I would normally show the resulting effort. Unfortunately I lost the images and I just can’t find them. And of course I’ve already mangled the roofing and taking it down for the install.

I did find some smaller photos of completed test areas that I did so you can at least get an idea of the finished look.

Unfortunately I lost my completed picture but I had one of a small section.

It’s pretty easy and really, on a completed sheet of roofing, in a dimly lit area, it really looks great.

Hope you learned something new today.
