Title: decals
Post by: scott matthews on December 12, 2010, 08:21:09 AM
Hello everybody. I'm getting close to finishing my model and was wondering if water based decals will stick to monokote? Plus do you have to put something over them to protect them from fuel any help would be appreciated. thanks Scott

Well I have used them on MonoKote with no problems -- you do have to coat them with something like Krylon crystal clear before you place them in the water (that is if you are using an ink jet printer)

I think in the long run you would be better off with peel back decals (stickers) or else hand cut trim from Monokote.  Not "Trim Monokote", just more regular iron-on Monokote.

Fuel proofing water slide decals takes a good coating of really fuel proof clear, and putting that on top any iron-on is questionable at best.

These planes, finished in Mono with Mono trim have lasted a long time for me.

I wasn't able to get them to stick to Monokote. They'd just peel off unless they were coated (including the Monokote).

HI Randy,

Are you talking waterslides?  If so, what brand paper were you using?

On the ALSP printer (MD 5000) it is general practice to coat the sheet after printing anyway.  I use anything clear that will not wrinkle when the top coat goes on (with a painted finish).

Thanks
Bill

Bill,

Not coating the decal. I put decals on my original Ringmaster Deluxe. They keep peeling off in flight. Sigh.

I tried a bunch of stuff. putting down decal sealer, softening agent, etc. Even tried the Windex idea used when attaching Monokote trim. Eventually the decal would just peel off. On the new RMD, I covered it with Coverlite and put on decals and shot the whole plane with catalyzed polyurethane. No problem through a whole season.

I know Alan Brickhouse got decals to stick to transparent Monokote with his Olympus, but I don't know how he did it. I think he may have shot the whole thing with a catalyzed topcoat.

Thanks for the input guy's, but these are the decals that come with a brodak kit so I will just have to trace them onto some monokote trim sheets.Scott

If they are the peel and stick that some Brodak decal are.  Just clean the surface of the Monokote real well.   H^^

I haven't tried water slide decals on Monokote, but I do use ink jet waterslide decals on dope finishes. I have found that dope makes the best fixitive for them, and seals the decal really well. I just brush dope on before cutting out the decals. After they are applied, I go ahead and dope over them to seal them into the finish. I brush all my finishes, but I am sure spraying would be fine also.
