glueing portrait?

[gilljc]

I have finished cutting on first portrait style picture, and have made a backer to mount it on. I have painted backer board black with satin finish, and am wondering what is the best glue to use to bond them together? I have masked some parts of the backer to try to improve its stickability, but am worried that it may still not bond thoroughly on the paint

Hi Gill. I use tight bond, its just about the best. When you apply the glus to the underside of the portrait avoid getting any to close to the cut outs, you do not need much but make sure you have glue all around the border. I always clamped my portraits with the backer fixed in place and using thickish timber both sides. I would not use the masking tape personally.

I use quick drying pva that I get cheap on the market , I usually leave areas unpainted on the backer that you are not going to see , if you have painted it already just sand it back that way you have two surfaces , otherwise as you say the paint could pull of as no matter what you use it will only be glued to the paint surface and could pull away

if its just 6mm ply I just glue and cover with piece of paper and stand something heavy on it for half hour as you only need a thin film of glue around edges mostly as if wood flat it will keep the thin bits of portrait against the backer without needing to glue the tricky bits

A further vote for (Titebond ), I use both (Titebond II & III), you can also use oil on your projects, and this does not effect (Titebond), assuming the (Titebond) is set first.

Oils I have used, Lemon, Tung and Teak finishing oil.

Take care.

I use PVA glue - some German name that I can't remember offhand - and nothing has come adrift yet, even from ones I have dunked in teak oil, although my backing is generally coloured card.

I use wipe on gel stain to colour the background. It's easy to apply, dries fast, comes in a variety of colours and, crucially, it doesn't seal the wood, so you can be certain that the glue will bond properly.
I also use Titebond, which I brush on to most areas. I put the portrait and backer on top of a couple of 2x2 scraps, clamp the edges and put an undersized board with some weights on it on top to make sure everything sticks. After about 15-20 mins I take off the board and check for glue squeeze out, which I then remove with a craft knife/scalpel - easy enough to do as the glue will not have fully bonded with the
wood's fibres yet.
