It’s in the prep. We change shows every 6-8 weeks, and some of the artists want to change the wall colour away from a light grey, so often a few coats of dark low VOC paint and only a week or two to turn the shows around. Lots of ventilation to dry the walls (I tell them at least a couple of weeks). Then follow the IPA/water 50/50 mopping protocol.
Then a few more coats to switch back to pale neutral. Then follow the IPA/water 50/50 mopping protocol.
If someone has painted with an easy clean emulsion, then they’re in for a world of pain, as the paint normally has silicon or ptfe built into it, and you’ll be lucky to get a high grab vinyl to take it.
Our walls are mdf, and we use Leyland trade vinyl matt. We can get non-agressive canon ijm538 to hang a couple of days after painting, but we ventilate, and do three reps of the IPA mop protocol. We don’t post heat, and where the works are not laminated, we apply with a minimum of pressure, to avoid scuffing the prints
Temperature has an impact -below 10degreesC, it gets dodgy. IJM538 is cheap (for aqueous), and little different from the cheapest generic materials we have tried (but has a slightly better colur gamut)
I’ve only had one failure (after using the ipa/water x3 protocol), and that was on what should have been a well cured solvent painted wall. There was a cold water riser to the building directly behind the wall. But I’d not expect that in a gallery. No amount of scuffing, IPA, heat worked. So we redesigned the graphic, and avoided the problem.
