How to Repair a Leaking Gutter Union Joint (and Poly Tunnel)

here's an effective way to carry out gutter union joint repairs

you'll need roof repair compound and weed control fabric. do not use bitumen, it is cheaper but it is not the best product as it is not sticky enough.

a ladder stand off is needed

for a gap like a window just strap on a piece of wood as shown

cut the fabric to fit the gutter joint

clean the joint, plain water is just fine

previous pointless sealing with silicon

joint clean and dry.

keep the sealant in a bucket to prevent spillage

joint clean and ready for sealant application

apply the sealant generously, wear gloves as it is very very sticky

then apply the piece of fabric pressing it down, the sealant must penetrate the fabric

then apply another coat of sealant on the top. job done.

this method is also useful to repair rips in a poly tunnel, you need to apply the garden fabric on both sides (inside and outside)

as shown earlier, it does a good job.
