Amazing stuff

We have had our outside oil boiler for 7 years and our regular guy came to service it in October to give us the bad news it’s leaking and the maker told him only five year guarantee and the part we wanted was not available. There exact words were discontinued.
He then told us new boiler fitted would be around £5/6000 but we could try this miracle seal what had we to lose he ordered it he put it in 2x250cl.you put it into the system let it run through and it starts to seal all the holes. 10/15 minutes later no more dripping bottom of the boiler dried up.
This was October just started to leak again ordered two more bottles put the in now dry again. So all I can say is definitely a 10/10 product love it and saved us £6000 and will get new boiler in summer.

Thank you so much for sharing your experience!

We’re delighted to hear that the sealant helped stop the leak and saved you from an immediate replacement. It’s great to know it worked quickly for you and has continued to keep things dry when needed.

Wishing you all the best until your new boiler is installed in the summer and we’re glad we could help in the meantime!

Best regards,
The Sticky Stuff Store 😊

Annoyed!
Not for use with Air Source Heat Pumps

This has completely ruined my ASHP I have gone from 28 l/min to barely nothing. 3 way diverter valve isn’t working properly and hot water tank is flowing back into the heating circuit. No idea what it has done to the heating exchanger.
