We have a high wall in our house, approx. 30' or so. We're wanting to paint it but haven't figured out a way to do it safely. I have a 17" step ladder, not tall enough, I don't feel confident using an extension ladder. I thought about renting some scaffolding, but someone told me that's very pricey. Does anyone have any experience in renting scaffolding for a weekend project? Any other ideas? It's an inside wall so spraying is out. I'm really thinking about hiring someone to do it. Might save a lot of hassle.
