Perfect for felt roofing
26 May 2015
By LD66
, Manchester
" I bought this product for use with the overlap when replacing the felt roof on my shed. Easy to use and sticks quite quickly. I wanted to something to prevent water ingress and so far, this great product has done the trick. Very happy with the performance and confident the roof will last longer than the last one. "

No Nonsense - True
23 Jun 2014
By Beenblue
, Swindon
" Bought 3 tubes to seal cover laths against roof verge. Applied a good bed to the joint and smoothed over using finger and soapy water. Easy to finish and as it was a very hot day was able to paint within the hour. Took the paint finish very well. As the sealant is semi setting hopefully means it wont crack! "

" 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

By beejay

" 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 "
