"used it to seal a few awkward gaps in drain pipe connections. I applied it to dry surfaces (rusty cast iron, PVC) - it did a great job - bridges gaps, holds its position well. Just dont get it on your hands or it will be there for a long time"

An excellent product
17 Nov 2012
By beejay
, Leamington spa
"I used this on a leaky old garage roof constructed from cement corrugated roofing sheets. the overlap joint sealant had hardened and became compromised.
I squirted a thick layer between the joins and the result is a leak free roof.
It has not been in place long enough time for me to assess how long it is likely to last however this product doesn't harden so I am hopeful fairly confident it will do the job for many years"

Does the Job
26 Sep 2011
By rodroy

"Used for patching up the corner of some felt roofing. Competitors stuff is often too stiff and not workable and does not stick unless firmly pressed into place. This can be applied easily from the tube. Sticks in place, can be worked and has remained rubbery so far resisting the rain.
Too early to tell reliability but if as good as the No Nonsense builders sealant then no worries.

"This is good value for repair of small leaks and bedding roofing felt. I needed to bed a small section of roofing felt and found that this product was ideal as it made an immediate bond between wood and felt with no slippage."

fantastic roof sealant
15 Apr 2011
By urematey
, Bristol
"i purchased a few tubes for a corrugated metal garage roof i was building, and used this product to bead on joints/overlaps.
very easily applied as you'd expect from a gun, lovely adhesion, which you could feel, if you were unlucky to need to adjust the two surfaces.
easily cleaned excess.
good packaging.
does have a shelf life which is worth noting."
