Sorry this isn't a MOS thread, but I've been trying to figure something out and can't come up with a good practical solution. Say I needed apply pressure to something that was pretty much vertical, but the object being applied was horizontal. (Think of putting a horizontal stripe on the wall). Pressure needs to be applied for a few hours, so holding it there is out of the option. It'* about a 3 foot object that needs to be held flat against the wall. Tape will not keep a tight enough pressure. Let'* say it'* also 2-3 feet off the ground so you can't really use the floor to your advantage. So who'* got some ideas on the cheap?

why not use the floor, just use a 2x4 or whatever and leverage it against the object. 3 feet off the floor, you would need a 5-6 ft pole, secure the end on the floor and lean into the wall object

if it was tall enough you could use the back of your couch or your kitchen table propped up to hold it in place.

I would suggest using a 2x4 or similar...the same way they hold walls up in housings that aren't finished being framed.

Simple bracing exercise...just make sure the brace is properly anchored on the floor. I would use a sheet of plywood (thinnest possible), slide 3 2x4'* spaced evenly apart to distribute required load and brace against the floor.

Thanks guys. It'* out side, so I'm going to try something hopefully this long weekend weather permitting. Probably just fab up a wooden frame and anchor it to the ground/foundation.

Helium. Fill the wall with helium that the object is on. Then you can pick it up, lay it flat, put weight on it, and when it'* done, let the helium out after you put it back upright!
