Hello
I am in the process of cutting "strips" from 6mm MDF, which I will glue as trim/mirrors on new white (boring...) wardrobe doors.
These will then be taken in to be spray-painted.
The question is, what should I attach these "trims" with, I was thinking of gluing, but what glue should I use??:)
Anyone who has done something similar and wants to share how they did it??
 
PL600 or something like that...?
 
pl600/400 or some other type of cartridge adhesive will probably be too "thick"
You probably need a regular wood glue like casco or similar. Wipe off excess before it dries.
 
Well, it shouldn't be too thick. What's a bit tricky is that MDF absorbs and the wardrobe doors are glossy...
Saw in another thread about Casco Superfix, does anyone have experience with it?? :)
 
I would have used Casco's polyurethane adhesive for that. I have used it before for various furniture constructions that have been spray-painted with good results.
 
superfix is okay..but why not just prime the mdf once with wood glue, lightly sand the door surface, and then glue everything with wood glue? Wood glue is underratedly strong...
 
Don't you have to sand quite a bit for the wood glue to adhere well? Otherwise, I agree that wood glue is underrated.
 
Wood against wood becomes insanely strong, but I guess the new white wardrobe doors are laminated? Then I would absolutely not recommend white glue, but rather go for construction adhesive - like PL600/400 Sika or Casco. Don't apply a thick bead, and place the doors on a flat surface so you can press the moldings firmly; that way, it doesn't add much...

Yes, the doors are probably foil-coated or melamine or whatever it's called, anyway they are brand Marbodal. I should probably sand them to make sure the paint adheres better as well. I have polyurethane glue at home, should I use that or is it considered white glue too? How much can MDF shrink when it comes indoors?
 
PL400 works great if one of the surfaces is absorbent, e.g. MDF. It is also water-soluble, so any spills are easy to wipe off before it hardens.
 
PU glue is great for most things... but a bit unpleasant to work with... but I have a bottle of Sika PU glue that has lasted forever... you use so little of it and it becomes so strong :-)

There's also Pattex No-More Nails... I think it's fantastic for quite a lot.
 
Thanks for all the tips:)
Unfortunately, it seems like there will be no moldings at all on these doors now....
It turned out that the doors are so close to each other that if I proceed as planned, they'll hit every time you open, since the moldings add so much.:@
So now it feels like a simple solution would be to just buy new nicer doors and install them!!
Does anyone know if you can buy just doors from Marbodal?? In the catalog, it seems to be mostly complete with frames and everything!

Is PL400 water-soluble? You're not thinking of PL600? ;)

Yes, PL400 works well for wiping off spills with water before it dries, I haven't tested with PL600, but it says so on the tube. I made the mistake once of using another glue, it had to be removed mechanically.
 
Since when did PL400 become water-soluble??!! Clean up spills with water??!!

On my PL400 tube, it says: "Uncured adhesive can be removed with clean petrol or Xylene"
PL600, however, is water-soluble.
