The tirolessa sprayer is a simple tool that makes stucco work a blast. I have used the tirolessa to quickly cover my fence, battery dome, and front gates with an inexpensive cement plaster. Spraying makes the plasters stick better due the impact effect and saves a good deal of time compared to trowling by hand. The setup is nothing more than a 60 gallon air compressor, some air hose, a wheel barrel and a tirolessa sprayer, which actually directs the plaster. The air compressor provides enough pressure to shoot heavy mortars a few feet by squeezing a trigger on the sprayer handle. Using it is similar to using a can of spray paint. A commercial shotcrete, blastcrete or gunite setup would cost tens of thousands of dollars, but this setup is perfect for the DIYer. Check out the photo gallery to see some of my tirolessa projects, and read on for more about my setup and to see a video of it in action.
I love rebar. It's most often used in concrete as a reinforcement, but it has a ton of uses. I've made a fence, a shed, and my future dome home armatures all from rebar. And since it's often made locally from old cars, it's relatively planet-friendly, too, and not very expensive. A 20-foot-long, 3/8-inch thick stick normally costs me about $4. I've purchased more than three tons of the stuff from a metal plant near the El Paso border, about 100 miles from my home.
