My nephew dropped off a roll of sheet metal (4 x 7) for temporary signage. The plan is to do solid vinyl layers for his logo. Question I have is reqarding prepping the sheet metal for the Oracal. How is there to do with this sort of material? Will wiping it down with Rapid Prep Cleaning Fluid be enough?
I always clean with dish detergent and water if the metal does not have a mask. I then use the solution I use for the application.
I always use a cellulose paint thinner to clean down metal, it just cuts through all the gerase and dirt that may be on it.
It really does stink a bit but it works fine. Just give it time to evaporate before applying vinyl
use denatured alcohol after cleaning with non ammonia based window cleaner - it is clean when the rag or paper towel you are using is getting pulled from your hand by the surface. Same criteria as vehicle wraps.
Is it galvanized steel, enamel coated steel or aluminum ? Galvanized steel with no enamel/paint coating is the worst thing to try to stick vinyl on. (I've been doing signs over 20 years). For enamel/paint coated sign material, usually aluminum, I just clean it off with Windex or Rapid Prep. Position the vinyl/transfer paper where you want it, and hold it with masking tape from the top. Lift up the sheet, peel off the backing paper, and 'mist' it with Rapid Tac or Rapid Tac II. Then start letting it down and squeegee into place. I know some signshops do 'dry' install only, I do when necessary but prefer a 'semi' wet method. I did an article in SignCraft magazine on basics of 'hinge method' application but it was a couple years ago and I can't remember what issue it was.
It is galvanized. We use the hinge method ourselves. My nephew is on a budget and trying to get around an ordinance rule on temporary signs for his first year. Like most new businesses the budget is tight.
