Rated 4 out of 5 by Very good Tried a few other roof sealers but none are as tough and rubbery as this. It's reassuringly thick to apply and plugs any flat roof leaks you can find. The only downside is it's quite expensive but if it last 5 years it's paid for itself. 19 Jan 2015
Rated 5 out of 5 by Amazing product Have used a few tins of this recently, although it's not cheap it is incredibly good... Really easy to apply (although need to chuck the brush after, so use a cheap one..!!) Have used for repairs in rubber roofs, felt roofs and sealing suspect edges and in every instance has worked perfectly all I would say is that you have to give it a really good stir first off 9 Oct 2014
Rated 5 out of 5 by Great Product This is the second time we have bought this product and it is excellent.Perfect for leaky roofs, we used it on another property before...no more leak. 12 Jun 2014
Rated 3 out of 5 by 48 hours no rain It says on tin : " Surfaces should be clean and dry, with rain unlikely for at least 48 hours. " What :) ??? Should not be sold in Scotland IMHO :)) But I'm sure that it does a good job in dry weather. If you need repair with reinforced fibres you should buy FLEXACRYL (screwfix) instead. That works in all weather. 7 Sep 2011

The instructions mention the time taken for the first coat to be touch dry. So how many coats would a flat roof need?

Answer: 
Thanks for your question, yes that would be fine but not advised for use on new sheeting. Be aware that the total surface area of a corrugated surface is greater than a flat surface with the same dimensions.

Answer: 
Thanks for your question. I'm afraid we don't recommend this product for use on caravan roofs, adhesion on this kind of substrate would not be sufficient.
