Simes Posted August 21, 2020 Report Share Posted August 21, 2020 I'm sorry to have to raise this topic again, but I need some help. I have seen comments in the past to the effect of: "If you can't repair Doc Martins, you are in the wrong job!" Which is not that helpful. I take on board the idea that some use superglue as a primer. I haven't done that yet, mainly because that hasn't been the traditional method and therefore, without dismissing that idea, I wonder if someone can point me in the right direction. I have used prepared surface and used Renia (Yellow) wait for 5 minutes and then add Bostick 50/50. Reactivate and apply soles. However, it doesn't seem to be very successful. I have tried the same primer with 6092 and that also seems less than reliable. What am I doing wrong? It only seems to be Doc Martins that I struggle with. Am I just using the wrong glue or do I need to change my preparation techniques? Link to comment Share on other sites More sharing options...
Gray Posted August 21, 2020 Report Share Posted August 21, 2020 I have just used Bostik 50/50 no primer and never had any problems. Pearsons and ironplanet uk900 2 Link to comment Share on other sites More sharing options...
Michael Posted August 21, 2020 Report Share Posted August 21, 2020 Anything plasticky I use Renia Rehagol yellow primer with Syntic Total, although not tried it on DM soles! Always thought they were PVC based so only a PVC adhesive will bond them. Link to comment Share on other sites More sharing options...

kobblers Posted August 21, 2020 Report Share Posted August 21, 2020 I've NEVER used primer - just 5050, like Gray. Glue the new unit, let it dry and then reheat until it's pretty hot bot not to the point of melting or warping the unit - then glue the shoe, let it go slightly off but not fully and then apply the heated sole and use firm pressure to bond. I don't use a press for this as they can sometimes warp the unit and then they're a right git to remove and correct. Rick. Link to comment Share on other sites More sharing options...
keithm Posted August 21, 2020 Report Share Posted August 21, 2020 Most presses have, or should have, pressure adjustment, so in theory you can vary the pressure on anything you press from light to heavy. It saves using your hands and pressure on your joints, which can become a problem later in life. Link to comment Share on other sites More sharing options...
Lee Posted August 21, 2020 Report Share Posted August 21, 2020 no primer, no press, little or no heat, catch just as the glues on the turn. no problems. Link to comment Share on other sites More sharing options...
Simes Posted August 21, 2020 Author Report Share Posted August 21, 2020 Think that's done it! Going to leave to set before trimming and we'll see how that goes. Thanks all! Link to comment Share on other sites More sharing options...
x minit uk Posted August 22, 2020 Report Share Posted August 22, 2020 Yep no primer and very little heat or pressure , if you press it to hard it spreads and causes bonding probs. Link to comment Share on other sites More sharing options...

elfman Posted August 22, 2020 Report Share Posted August 22, 2020 1st choice would be foss 8016 ,2nd choice would be renia multi colle ,bostik would only be used as a very last resort Link to comment Share on other sites More sharing options...

elfman Posted August 23, 2020 Report Share Posted August 23, 2020 when foss 8016 was available it was the only one i would use for p.v.c or doc martins used it first time in 1971 never lost faith in it since it appears to have vanished from the market trid a number of others the best i found comparable to the 8016 is the multi colle , bostik i have tried just do not like it one bit Link to comment Share on other sites More sharing options...
ironplanet uk900 Posted August 25, 2020 Report Share Posted August 25, 2020 50/50 ,not primer.. clean new units with thinners, no need to scour or roughened up. Warm both surfaces and press on with your hands only. You can not use a press with Dr Martins. Tip... you only need a very thin layer of fresh 50/50. Dont make the mistake of caking it on or bothering with two layers. kobblers, Auto Key Wizard and x minit uk 2 1 Link to comment Share on other sites More sharing options...

Ive done many D.M.s over the years, 50/50/ and always use a light press, easy job. keithm 1 Link to comment Share on other sites More sharing options...

The construction of Dr Martins is not ideal for most presses. A bag press may be suitable, but I wouldn't use one of them either! Wink! Link to comment Share on other sites More sharing options...
cre Posted October 25, 2020 Report Share Posted October 25, 2020 Clean with acetone, apply syntic to both surfaces and wait. Reheat both surfaces and hand press together and leave it overnight. Knife trim and put in the grooves next day. A reliable method and a fairly simple way to make 60 quid. Link to comment Share on other sites More sharing options...
