    Works but expensive

    Does the job but expensive and gives off slight smell when heat oven . Used it to glue glass to seal on door. Hopefully smell will go soon.

    Quick and Easy Fix

    The seal on our oven door has been ripped for some time, unable to change the seal as oven is 20 plus years old but everything still works. Ordered a tube of this sealant from espares and the seal is all good again. Would say a smaller tube would be better value. Excellent job

    A Big Help

    Inner double glazed panel on oven door had fallen out. The availability of this stuff made me realise how to fix it. Careful lining up was needed - marked with masking tape. then removed with excess sealant. Absolute cleanliness of the mating surfaces was achieved by using kitchen degreaser, followed by meths. So far so good after a bit of roasting.

  • If it was originally glued on and not screwed then this will do the job perfectly. You need to leave it a few hours (eg overnight) to set fully before use. By hemlock1961 - East Sussex - 13 February 2010
  • In my opinion yes, but even if it doesn't it won't cost the earth to find out. I say give it a go! good luck. By femfixit - Essex - 11 November 2009
Answer this question

Our 10+ year old oven's plastic door handle has become detached, evidently because the metal screws holding it to the door's metal frame no longer engage with their holes in the plastic handle (the holes must have lost some thread). Some screws holding the oven frame in a chipboard surround are spinning in a similar way, although I don't think they affect functionality (it seems solid enough). I thought about repairing both with superglue, but read that PVA can produce cyanide gas at temperatures above 230C so this seems rather risky. As Heat Mate is OK to 300C, is it the best product to fix the various screws in place, or is some other adhesive/sealant better?

  • Have you tried different bolts, either longer ones of the same size to use the thread further in the handle, or bigger ones and rethread the plastic of the handle. This stuff probably would do the job but it is a big cartridge and you would only need a small amount. The holes in the chipboard you could pack out with matchsticks (remove the heads obviously). Works as a sort of DIY rawlplug. By hemlock1961 - East Sussex - 13 February 2010
  • Answering my own query after waiting in vain for anyone else to do so... and after hitting upon the revolutionary idea of calling the manufacturer (doh!)... Their technical services department were very helpful, and said (a) the sealant is not 'structural' so might pull straight out again if subjected to any significant load; (b) two-part epoxy resin adhesives (araldite etc.) are fine at high temperatures and stronger than sealants, so that's what I need. There were incidentally other problems I noticed from the docs on the EverBuild website and they confirmed, e.g. 'minimum width 6mm', 'do not use on soft metals such as brass', etc. By Ozaru - - 15 September 2009

  • You need to scrape the old stuff off and clean off all grease with meths or similar. By hemlock1961 - East Sussex - 13 February 2010

    Hi Nigelashley, I'd advise removing as much old sealant as possible, as the new sealant will adhere much better to the surface of the oven.

    Hi Mums, this sealant is made just for this purpose - it will re-stick your door glass just like that.

  • yes it works, but is a bit messy, dont spill any By doedoe - liverpool - 20 January 2009
  • Although the oven has only been used twice since applying the new adhesive it seems to have done the job. It was used to re-fix the inner oven glass (NEFF) which had come adrift after 10 years of regular usage. I'm hopeful that it will last at least another 10 years, when it will probably be time for a new one! Beware though, the sealant / adhesive can be very messy to apply if you haven't done it before. Need to spend time to ensure that the old surfaces are thoroughly cleaned up. By Ricardo - South Cumbria - 19 January 2009
