anyone have any suggestions - I have the 3'x2' signcade white A-Frames - I am printing on 3651 oracal with 210 laminate - how do you guys prep your signcades? - I am having a heck of a time having the vinyl adhere - I have tried sanding with a light sand paper and heating the surface first - but the vinyl does not want to stay down - I am using dry application but still I could pull it off easy - any suggestions - PLEASE!!!!!!!!!!!

All mine I buy have a sticker on them that says you have to clean w/ alcohol and then torch it. I've never once had problems with them sticking directly to the surface.

I mount to coro and use six stainless screws to attach the sign (4 corners and the middle sides where it would bow out)

Never had anyone complain.

When you torch it you will see the moisture/oils leave. If you use too much heat or do not move while doing it, it will melt!

the signacades that I get come with a warning that straight vinyl will not adhere to it. I also just apply to coro and then mount on there, it makes it nice as a selling point to customers IE: interchangeable signs ;)

We use a plumbers torch and go over it several times, you can see the "halo" as it
changes the plastic.

+1 for torching. just go over it at a semi quick pace. you'll visibly see the change, and then you are all set to mount. I have used 3651 with no problems.

Adhesion to plastics

Most of the plastic A-Frames are made from polyethylene, a low surface-energy plastic. By its oily nature most adhesive vinyl films won't stick to it.

Heating the surface of this material with a flame torch increases the surface energy of this plastic thereby increasing adhesion. You should apply the vinyl film immediately after torching. Any good brand of adhesive vinyl film should work, although one with a solvent-based adhesive will be more reliable. This method works great for short run of A-frame signs.

If you have a large run of A-frame signs, consider using a material especially for plastics which will save you all the labor time of torching. LG just developed a product for this named LD3870. It's about $240 for a 54" x 150' roll so it's an affordable solution.

Heat Gun, NO
Crème Brûlée Torch, in a pinch, but NO
BernzOmatic... yeah baby!

some actually have a sticker on them, but i guess they forget to torch the surface first...
cuz the instructions usually fall off.

JR... the coolest thing is... now i can offer signs raw, al dente, lightly toasted, well done or blackened.
most clients like theirs "well done" but blackened is the most fun.

mums the word on the blackened option... or my husband might take my torch away.
