Rated 1 out of 5 by from Water absorption problem Hi, Firstly, I would like to mention that isoflex was applied according to the instructions on the can and the surface was cleaned before application. It rained 4 days after application. After 2 weeks, I realised that isoflex turned to greyish colour. When I closely examined, the thick regions turned to sponge with water absorbed inside. Water bubbles were coming from inside when I apply pressure with my finger, and that's why the colour turned into greyish. Polymers absorb humidity, but this amount of absorption and change of chemical composition is unacceptable. Furthermore, it is not a cheap product. Now I have a roof with scattered grey colour regions. Please avoid this product. I can send you photos of the result.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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

Dipper roof spot

can this be applied on depressed or low level flat roof spot? will this self level itself?
Asked by: ravian
Thank you for your enquiry. The product will cure through where applied thicker, alternatively it can be built up in layers.

flat pitched roof

Hi, Would this be suitable for a plywood pitched shed roof? Also, what primer is recommended. Thanks Steve
Asked by: easyDIYhelp
Thanks for your question. Yes that would be fine, if the roof is sound and in reasonably good order the use of a primer will not be necessary.

Painting van floor

Could I paint my van floor with this paint to waterproof it?
Asked by: Phillipflop
Thanks for your question. Unfortunately Isoflex wouldn't be suitable for this application, it would not withstand the wear and tear involved.
