Yesterday's project was a handpainted banner, this morning, all three colors were still tacky.
I figured I must have been to stingy with the enamel kote. As the morning wore on, two of the three colors have dried. The last color is still tacky as I type. I tried the hydrogen peroxide mist trick, more that 2 hours ago.
The paint that is not cooperating, was older than the rest, can't really say how old. I read that with old paint, sometimes the drier drops out. Which as I understood the hydrogen peroxide would/could cure.
I have another banner headed my way, but was hoping there maybe just one more trick out there.
Thanks in Advance.

What do you do with the hyd. peroxide? I seem to have missed that tip... Cat

After researching this problem on this board, and theletterhead BB. I found the following.
-notes from Kent Smith - "When the dryer is in question, a simple solution is to take a spray bottle with hydrogen peroxide in it and mist the air lightly above the surface. Allow the mist to fall and this should dry the paint or varnish in an hour or so. Air flow at this time certainly is important. Keep this trick for future reference. This only works on alkyd enamels and related varnishes, not urethanes or acrylics although it will work on waterborne acrylics. Caution, don't mist too heavy or the finish will water spot."
and from
- Cam - "If I have my chemistry right, alkyd paint dries as the resin molecules bind with oxygen. Hydrogen Peroxide is a water molecule with an extra oxygen atom (h2o2). The extra oxygen molecule has a very weak bond and easily escapes as a gas. This would put a lot of oxygen in intimate contact with the resin, speeding the drying process."
UPDATE: I discussed the problem with my banner supplier, who told me an old signpainter's trick - which is to dust it with talcum powder. I tried that on a small part, and it removed both the tackyness and the gloss from the paint. It's now just over 24 hours ago that the paint was applied and it seems to finally be setting up - don't know if the hydrogen peroxide helped or time itself.
In the morning I should be a happy camper once again . . .

The color was mostly violet, with a little reflex blue and a couple of drops of red.
George-
I would have to agree, on all points regarding the vinyl ink. I still have trouble getting it to flow like paint, because it does dry so fast. What do you reduce yours with? It also destroys the brushes having to clean them with lacquer thinner, what are you using?
Thanks,
Bruce
