A Life Saver I've used this for years to keep an old flat roof fully watertight whilst I decide whether or not I want to pay out for an extension. Easy to apply, looks good and lasts for years. 29 Jun 2015
Great product Used this at the weekend on a concrete flat roof bit of rain through the night first time in ages have seen water sitting on roof rather than seeping into concrete. 26 May 2015
Brilliant Used isoflex in the summer and sealed the top of my flat garage roof excellent product completely stopped the rain from coming through the roof. Easy to apply just paint it on and let dry. 11 Nov 2014
Brilliant Stuff After doing lots of research and looking at reviews I decided to buy a few buckets of this stuff to redo my garage felt roof. I simply poured and rolled it on top of the felt and it creates a perfect seal against all weathers. Much cheaper than completely redoing a felt roof and looks awesome too. The product is fairly thick so I would recommend putting the tin in a bucket of boiling water for 5-10 minutes to decrease its viscosity. Also give it a stir afterwards. Top stuff, highly recommend! 4 Jul 2014
