Glueing Mirrors

Discussion in 'Technical Help' started by Baldyboy, Jun 30, 2014.

  1. Before I have to buy a new mirror for my 2005 fugly, wonder if anyone can recommend any decent glue for a mirror body (believe they are moulded in a polypropylene type plastic) this is resistant to super glue, araldite, plastic glue etc etc I cant find a used mirror so may have to resort to a new one. Cheers ears
     
  2. bet bostick would do it so long as you roughed up the plastic a bit first.
     
  3. bostick Original won't it's the plastic that they use think it has a high oil content it's weird stuff.
     
  4. How is it broken? If it is polypropylene it is difficult to glue, I have some polyP welding rods and some scrap PP from a bumper. I was thinking you could mealt some scrap PP into the back to hold it together depending how its broken.
    Plastic usualy has a stamp on it telling you which plastic it is
     
  5. I think a 2 part epoxy like JB would work providing you key the surfaces properly.
     
  6. Cheers guys you are all stars
     
  7. If it is polypropylene, bugger all will stick it.......

    .....that's why many adhesives come in plastic tubes made from polypropylene.

    Lots of car parts (bumpers 7 mirrors etc) used to be ABS, but some are now probably polypropylene.

    However, I mended one of my SS black mirrors with Araldite very successfully..........I reckon it is ABS (17 years old).

    One on the car was done with Araldite and mesh.....

    ......I grooved the cracks and along the cracks drilled every 6mm with a 2mm drill, which I countersunk on the outside.

    I then tacked the mesh on the inside with Rapid Araldite and when that had gorn orf, I injected Araldite ino the holes and along the crack, spreading the stuff across the meash where it came through.

    The c/s forms a plug which can't pull out and the mesh keeps the plugs and crack together......

    Finished off with more Araldite and then filler............Sprayed with rattle cans, primers and top coats.......doesn't show.
     
  8. Was waiting for your reply al, nearly posted it in the ss area ;). I repaired my ss mirror originally with araldite and it kept for a while but this plastic is oilier if that makes sense. Done it with araldite however it's hardened and just peals off. Will try other glue but the way it has broken where the stem meets the body makes it tricky.
     
  9. I haven't long ago mended some hard body armour which is definitely polypropylene, but for the life of me I can't recall what I used and I have chucked the tubes away..........but I used the same principle of drilling and countersinking, with mesh both sides.

    Post some pics of your mirror............I might see a way of making it work while being strong.
     
  10. Al here you go pre and post glue. It is araldite yes I know what it looks like.

  11. Yep.............that's a mess.........and that doesn't look like my Araldite............looks more like my............................

    I bet you a cheese sandwich, if I had it here, I could deal with it......

    At this stage I can see exactly how I would do it.......

    Suppose I fixed it so it was solid, could you finish it off with filler and paint?

    Mind you, I could replicate that finish in the actual paint or filler.....
     
  12. Have you tried Q-bond?
     
  13. Thanks for the offer al, much appreciated. I am out on it at the weekend and will see how it withstands the vibes and speed. I am thinking of using a top hat fixing got something I think I can use then couple of small grub screws or self tappers might do it. Will let you know ;)
     
  14. From what I can see of it, what I would use would either be a flanged bush washery tye thing which you find at the end of wardrobe hanging rails,
    and pop rivet (3 maybethe flange to the mirror with the sleeve of the item around the stub of the mirror, which is pushed in with Araldite around it........then file down the rivet heads as much as possible and smooth the whole lot over with some plastic filler..... the bumper stuff would do that.

    Or, I would find a steel tube of nearly the correct diameter of the stub (split the tube to fit if necessary) and also split the end of the tube so there are tags (2 minimum or 3 preferably) which can go inside the mirror and rivet from the outside......then the same finishing process again.

  15. I have had some good success using a product called 'Plastic stick'

    It's a stick of what looks and feels like putty. You tear off the quantity needed, and mould it in your hands to start a chemical reaction, and then press into/around the area for repair. It quickly hardens and sticks to seemingly all plastic materials .
    I have only just discovered this product and so far have carried out repairs to my cars broken wing mirror, which I should imagine is made from the same material as your mirrors, and also done some fairing repairs that I couldn't get good results from by plastic welding.
    Great product, highly recommended.

  16. My top hat type thing is your flanged bush washery type thing al :). Thanks, will have a look see and sort it this weekend. Cheers chaps
     
  17. Btw the stick is not expensive, in the region of £7 iirc . Found it on e bay
