“£££ spent on a specialist epoxy repair system… failed in under 5 years.” This timber repair was carried out using a well-known epoxy resin repair system, complete with correctly formed conservation joints and all the preparation the manufacturer specifies.
The sales pitch is that these systems flex with the timber and provide a long-lasting repair. Unfortunately, in this case, that’s not what happened.
The resin has remained rigid while the timber has continued to move naturally through seasonal expansion and contraction. The result? The repair has cracked, separated and failed long before most would consider acceptable.
What’s particularly frustrating is that the repair itself wasn’t the issue. The conservation joints were formed correctly, the product was applied as intended, and yet here we are less than five years later looking at significant failure.
There are two major manufacturers of these systems in the UK. Anyone familiar with them will probably recognise which one this is purely from the colour of the cured resin.
I’m not posting this to start a witch hunt—every product has failures—but it’s a reminder that marketing claims and real-world performance don’t always align.
Have you experienced similar issues with epoxy timber repair systems? I’d be interested to hear your thoughts and experiences.
