Not as easy as it seems: I had ten goal-post protector pads to letter- writing & logos on front & back of all- and everything outlined. The pads are a banner vinyl (like Santex). For durability I figured I'd do them with vinyl screen ink (sort of lacquer-based), rather than acrylic (water-based) banner paint. I masked all areas with Aslan grey mask- some bits with the heavy duty fabric mask, and some with the ordinary mask, and put the outline colour down (white). (hand- brushed) That had 4 days to dry, and I put the next parts over it (masked with the ordinary mask) and airbrushed the black vinyl screen ink. That had 4 days to dry. I then masked over that and airbrushed yellow down (it butts up to the black & the white) and if I removed the mask immediately, it was ok, but on the first four, I left the mask on for maybe 12-15 minutes before removing it, and the black is now covered in the adhesive from the mask. I tried using some Orange-Solv adhesive remover but that dissolved the cured black into an awful smudge, and left the residue. I then tried mineral-turps, figuring that being lacquer-based, the ink would be impervious to the turps, but it just dissolved it like the orange-solv and so I cleaned the mess and came here for some ideas! Oddly, also, the heavy duty fabric-mask tended to leave residue on the bare banner also, but cleaning it, though tedious, isn't a problem. It's just the gluey bits on top of the screen ink that I'm stumped over. It seems that the vinyl thinners must have had enough of a residue still in the paint/ink to affect the paintmask adhesive. It was a brand-new roll two months ago, and has given me no problems over enamel, nor over water-based banner paint, though it doesn't stick much over the acrylic/water paint. I cleaned the pads with Prep-vinyl, which is isopropyl alcohol first, and they had some hours to dry before ink or masking went on. Has anyone been here before and come out on top of this problem? The vinyl screen ink is Aussie-made, an equivalent to Sericol screen ink. ( for screen-printing on vinyl for stickers) Thanks

Try Rapid -Remover, works great!

Thanks Mike- I'm not aware of it being stocked here in Australia ( & never had a problem before, needing it either- the orange-solv usually does the trick)

Hiya Ian, As silly as it sounds, try more paint mask or duct tape. Press it on the area that needs to be cleaned and pull it off at an angle or with a sideways motion instead of peeling it straight up. Another chemical that I use is bestine. It's great for cleaning my inkjet prints because it doesn't attack the ink or coating while removing fingerprints, etc. Bestine is also great for cleaning adhesive residue off polystyrene. Try that with a citrus based cleaner ; )
Havin' fun,
Checkers

Thanks Brian, I'll try tomorrow with duct tape- didn't think of that before!

Silly as it sounds Ian .... try dusting the adhesive residue with talc powder and rubbing it off with the ball of your thumb!

In the past, I've had very good results removing adhesive residues by using Rubber Cement Thinner. I believe that it's benzine based, but it usually doesnt harm most CURED paints...but it is an effective solvent for adhesives.

Some feedback: the adhesive layer was very thin & very sticky. Duct tape, and more of the original film made no difference. Talc, once I'd wiped off the mess and got some grip back into my fingers, also just stuck to it and stayed there- it wouldn't ball up and come off. I eventually used some cheap WD spray to wipe it up. It took a little background with it but that was tolerable and fixable. The whole thing seems odd to me, especially the idea that mineral turps lifted the lacquer-type ink. The ink itself stuck really well to the banner material though. Thanks for all the help ideas.
