Leak Stop Sealant Spray Clear Mastic Large 500ml Instant Seal Roof Pipe Gutter Frames

Does what it says.

did not stop the leak in the guttering, quite disappointed, as quite expensive and thought it would have been good for the job

FOR ME IT JUST DIDN'T DO WHAT I EXPECTED IT TO DO, BUT YOU CAN'T RETURN ITBECAUSE THE CAN IS A MESS

Used this loads of times over a prolonged period but it did not seal even the smallest gaps.

Great Product and great service ,Many thanks,

excellent does what it said

It didn’t work

Spray nozzle snapped after less than 5 minutes of use
