Hi Heads. For those of you who have taken to using Acrylic Latex Paints for background colours, here's a Red Flag Alert!
There are some brands that have a soil-resisting feature that the paint exhibits upon curing. It's a built-in feature that's supposed to allow ease of cleaning, and give the paint soil & stain resisting properties. The problem with this type of paint, is that it also resists other paints and vinyls adhereing to it. It seems to develop a "waxy" surface after curing, and it makes any paints applied over top of it crawl, much like the "fisheyes" effect. Some of you may have had the experience of trying to apply vinyl lettering onto this kind of surface, only to have them curl up and fall off several days later.
Beware also, of customer-prepared panels, since they may have used this type of finish. This kind of paint can cause you a world of grief, and is most frustrating because neither paint or vinyls will adhere properly to it. It may even have some kind of silicone additive, but I'm not absolutely certain of that.
Here's hoping that you don't run into any of this type of paint.

Hi Ken. Yes I have had this happen to me also. I pretty much stay away from Latex paint except when painting the house!

I lettered a customer supplied and painted board a while back (cheap scade customer, you all know) and I ran into that problem. I told her when I did it though that I wouldn't warrenty or guarentee any vinyl letteting I did UNLESS it was on a substrate I myself made or bought.

I use Sherwin Williams DTM acrylic for all of my wood and HDU signs. I put vinyl over it with no problems and Oneshot paints over it just fine. Maybe this particular paint doesn't have those additives.

Can you tell us what manufacturers make these paints or what to look for in the ingredients. I use a lot of acrylic latex - Duron, Sherwin Williams, Ben Moore, etc. I haven't run across that problem yet.

I'm with Cheryl on this one! Sign paint for signs Latex for houses! Acrylics for crafts Kinda funny that ALL these paints are made for a specific reason. Why are some getting confused on the issue?
Good Luck for those whom THINK chemistry has somehow changed

Ive had more problems with one shot as a background than the latex paints I currently use. Porter and Ace Royal brands. Still use one shots for lettering, but have yet to have a problem with vinyl adhering to the paint. And Pat, I think the chemistry has changed drastically on latex paints for the better , and one shot for the worse.

I'm with you John! Our biggest competitor uses one shot as background and cast Arlon. We get lots of rain here and some wicked storms. The one shot blows off the MDO and some of the Arlon has shrunk big time. Too bad for him, lucky for us. We have a new customer from this problem of his, and lots more coming. I've also used on shot for striping borders at it's lowest rec. temp, and watched it skin over, then take 8 days to dry at 80F. There's better paints available. Like Dupont automotive chromabase.
