We built one of the sheds on our allotment from upcycled tin sheets. Unfortunately there were holes in some of the sheets - not ideal for building material. But using salvaged materials where possible is important to us and except for the holes, this was a great free building material. We opted for SUGRU to make our repairs, knowing that it would be waterproof, weatherproof and UV resistant once cured, making for a long-lasting repair.

Step 1: Sealing It Up...
The area around each hole was cleaned before SUGRU was worked into each hole. Once it had cured it provided a seal that is waterproof and resistant to UV, heat and cold, hopefully ensuring a non-leaking roof for many years to come!
