Vinyl Problem

[wildergraphics]

HELP
I am doing my first big sign job and am having trouble getting the vinyl to stick.
First off i am working with painted MDO board, semi gloss white and black dutch boy, outdoor premium paint. I could not get the vinyl to stick to the white but then i scuffed it up a bit with sandpaper and it worked.
Now i can not get it to stick to the black, i also scuffed it up a bit but it still wont stick.
I am using Oracal 651 vinyl. please help this could be a very big client.
Thank you

latex or oil?

Not sure about that paint. But if it isn't oil-based enamel, the vinyl will not stick. If it is latex (the kind you use water to clean up with instead of thinner), it will not work.

A lot of latex paints leave a "greasy" surface to resist dirt and grime.

Start over using One-Shot or Ronan bulletin colors.

Actually, there are brands of latex that work quite well with vinyl...you just have to find the one that works. Sherwin Williams Super Paint and Porters are a couple brands that many have success with.

Black is latex, i also just tried to stick to red oil base and that will not stick either. ?????

is there anyway i can fix the problem without starting over.

What about if he cleared it with Frog Juice. It should cover latex and the vinyl would definitely stick to it.

Ronan bulletin colors work great for us, never any issues with the vinyl sticking and the life of the paints are great!

Not if you want it to look like it was done by a pro.
1. paint stripper, chem resistant rubber gloves and a respirator.
2. sand to a smooth finish.
3. prime and repaint using proper materials.
4. get your merit badge for attendance at the 'school of hard knocks'. Don't feel too bad, we all have a few.

I've had good luck in the past spraying latex paint with an exterior clear polyurethane. It seals the surface and it will then hold adhesives.

is your paint good n dry ? That's probably why it wont stick. i've done plenty of latex (usually glidden hi gloss) signs. in fact, i wont use oil based anymore. if you scuffed it up, just go ahead and recoat it and let it dry for a few days.

Fred, doesnt that stuff yellow after time?

Fred, doesnt that stuff yellow after time?

I suppose so because it doesn't chalk. It takes a while though. The only time I've ever taken this route was with customer supplied boards and have never seen a case of it yellowing or causing any complaint.

i think your only shot at saving this short of repainting with an appropriate paint would be to try a layer of tycoat or possibly frog juice(spit) as mentioned above, but either way i would do a test on a small piece before investing a lot of time into either. the positive is that i guarantee you will never repeat this mistake in the future of your career.

if this is a sign for a customer, it needs to be done right so re-paint it with the proper paint.
