Hi guys, I was wondering. If you are going to fit decals over a fresh paint job,and you wont see the paint anyway. can you just clear over undercoat, or is there a reason why you would have to undercoat, colour and then clear?
Thanks Bren

I didn't know you had to clear !@#

Er no... only reason behind any of the prep work is that decals adhere better to smooth surfaces than rough. Any undercoat or acrylic is a rough surface... a clear or enamel is considered a smooth surface.
There is absolutely nothing stopping you from getting great adhesion by simply clearing the plain timber.
Any paint prep is done to make sure that on the cabinet edges you don't have a colour difference.. for instance, if decals are mainly black then paint all corners black and any gaps between the front and side decal is invisible.. leave this area another colour and it notices big time. Back of cabinet needs to be painted also.
But to reiterate.. if you can get the bare timber to a nice glassy finish you will have just as good adhesion as you would have if you had a painted glassy finish

my best results (so far) has been by not painting but using the orbital sander first with 80 grit to remove old gunk, 120 grit to clear up more and then a good go with 240 grit to get it super smooth and applying decals to smooth bare wood..

First off I cant copy and paste with my phone so I have to answer this way lol
pinball god: Ive noticed that bare timber really sucks up the first coat of paint, so I asume it would do tbe same to a decal adhesive and over time maybe let go in places.
joele: I understand your geting a super smooth finish, but my thaughts are the same as what I explained above. Im just trying to get maximum adhesion with less time, effort and cost.
Gav: that sounds like a plan for future referance. It will save a lot of time doing just 2 coats of clear instead of the undercoat, colour and clear.
thanks for your wisdom guys. ^^^

Primer / Undercoat prepares the surface for the basecoat. Something to do with "adhesion" - But the opportunity is there to spend more time preparing for the basecoat. You want a smooth surface. A "flat" smooth rather than a "finish" smooth. Then the base should go on like glass - but that's only for the decal to be applied to a flat surface. A clear is overkill. Even the clear will have the extra step of scuffing the surface to allow the decal to adhere to it. A light scuff is a good idea on the basecoat. I never clear cabinets.

A rush job is a poor job....take your time.
If it's worth doing, it's worth doing properly.

Well, he *might* be using Dulux paints :lol :lol :lol

Thanks again guys, I'm taking all this info on board.
-
how long do you guys recommend to wait to apply the decals after painting. I've been doing this for weeks and just finished the final coat - itching to put those damn stickers on!!
-
Depends on the paint you have used, but I leave it for at least a few days.
Like a fine wine, it needs time to breathe for best results. &&

I just want to pop the cork and be done with it! But will wait...it's already taken 50 hours to get to this point!

50 hours is a great effort. Don't be like me and be inpatient. With the chill it may take a little longer to dry and de-gas

Does it really? Mine's in pretty good nick, and I'll lose the yellow warning writing (I don't have a silk screen/stencil on hand)...plus I'm sooooo over painting :(

Yeah, it's my first time so even takin the head off took a while as I took my time and took a ton if photos. Doing the cabinet I took pinsanity's, retropin's and nino's advice and tried to do all the steps right. With a new baby and a wife that gives me stink eye at the very mention if pinball it's getting on to months now since I started.
-
I think weve all been there.. even running a business is worthy of a growl when a new baby arrives.. thank god I can produce money just by eating..LOL
If you didn't rub the back of the cabinet down then it doesn't need painting... I just assumed that the whole thing had been stripped
-
The old stink eye huh ^.^ I know how you feel.
