Perplexus Posted July 25, 2007 Report Share Posted July 25, 2007 I'd like to know how other repairers cope with attaching half-soles (and heels, for that matter) to the ghastly material that is currently used on most Clarks and Ecco shoes and many others. Over the years we've tried practically every adhesive we can find, with mixed results, but the bond between the new sole and the original material is seldom satisfactory. Perhaps there is a thread about this on the forum that I haven't found, but I'd be glad to hear what you guys have to say! Quote Link to comment Share on other sites More sharing options...

kobblers Posted July 25, 2007 Report Share Posted July 25, 2007 if they're only requiring a light to medium weight weight sole then we rub a fine coat of superglue over it, let it dry, rough it with a green scourer gently, prime it with renia and then use 5050 over the top. rarely get any back using this method. ( we only ever stick pvc soles to these materials btw) Quote Link to comment Share on other sites More sharing options...
Michael Posted July 25, 2007 Report Share Posted July 25, 2007 I use Renia yellow label primer with Renia Colle De Cologne.This sticks using both PVC or resin Quote Link to comment Share on other sites More sharing options...
Hugh-Candoit (ENG) Posted July 25, 2007 Report Share Posted July 25, 2007 Read the post on scoured edges and see if you can find the post on using adhesives. I fthe adhesive one has been removed I will redo it if needed but it is very long and takes a lot of time to do. there are as Tel points out several ways of effecting the job but it is important for you to understand the many things that go wrong and why so that you have a better understanding of the problems associated with promlem materials.

Perplexus Posted July 26, 2007 Author Report Share Posted July 26, 2007 Thanks for the feedback on this, guys. This forum is like a vast bucket of knowledge! The current manufacturing materials are a bit of a minefield, and I guess it would be naive to expect a one-answer-fits-all solution. We'll try the industrial chemistry that has been suggested, and see how it goes! We found that Freesole sticks extremely well, but it's a messy, long-winded and expensive method!

Hugh-Candoit (ENG) Posted July 27, 2007 Report Share Posted July 27, 2007 Freesole is a brilliant product in its own right but should not be used as a general purpose adhesive du the the cost and limitations of use. Ideal as an emergency where nothing else will stick----Freesole or Stormsure surely will....... on everything.... it has no boundaries.

Guest NZCob Posted December 12, 2007 Report Share Posted December 12, 2007 They are hideous things to fix, I think they are made of polyurethane with a TPR outer coating. I normally use superglue spread with a flat card over the TPR edge, and then Bostik 999 (I use this for 99% of synthetic materials) over the TPR and Poly once the superglue has dried. If I'm sticking micro/rubber/leather/eva to the surface I just coat the new sole with Bostik 1222 (I use this for all rubber/leather gluing) wait for it to dry (like a primer) and spread the 999 over the 1222. Heat and stick. I've very rarely had a sole come back since doing it this way. Same with TPR, which is that awful oily compound that the chinese seem to make all their shoes out of these days. Spread superglue over the tpr, and then carry on the same way as the 'ecco' type soles. I used to use Renia rehagol as a primer but had failures, and it stank like old socks. Now I just use the 2 types of Bostik and the superglue, and It works on 99% of my repairs. Quote Link to comment Share on other sites More sharing options...
Hugh-Candoit (ENG) Posted December 12, 2007 Report Share Posted December 12, 2007 I think you may be getting your material ID mixed up NZcob, easy to do with the new complex mixes. Chinese use Polyurethane TPR has mainly died a great death due to the problems of ageing, still around but not many manufacturers use it. TPR is not used on the outside where PU is in the centre, just a different form of the PU, as it hits the edges of the mould it compresses more, thats why it is glossy as opposed to the spongy middle. This may be what you think is a TPR edge. To compound matters even further the new mixes coming onto the market from the manufacturers at Thermoplastic Polyurethane, all one product not TR in part and PU in another. These are the most difficult to stick as each manufacturer will have a different mix according to their individual needs. (Bluffed my way thought that one didnt I!!)

kobblers Posted December 14, 2007 Report Share Posted December 14, 2007 we've just started to use the new renia tek 10 primer that's made for birch. we've used it on all the materials mentioned here so far with what seems like resounding success at the moment, although, time will tell if we get any returns. rick.

kobblers Posted December 14, 2007 Report Share Posted December 14, 2007 haha, scuppered ya it really does seem to do the job, from my experience with these crappy materials, if it ain't gonna stick then you generally find out within ten minutes of applying the new sole/heel, this stuff, so far, seems to be holding on everything a treat. obviously, like i said, only time will tell but i gotta tell you that i'm feeling quite optimistic. if all else fails, roll on the quickfix and the loctite Quote Link to comment Share on other sites More sharing options...
