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

I have a 1960,s "Nuralite" flat roof. This has wooden beams on top at 18" spacing to support some decking. I am thinking of painting ISOFLEX inbetween the beams to give a lomger life to the Nuralite (which does not leak) . Is t

Asked by: iowhouse
Thanks for your question. In theory this seems like a suitable application unfortunately the adhesion to the Nuralite is not something we could be assured will be successful so difficult to provide a firm recommendation.

ISOFLEX LIQ RUBBER

Can this be applied/used in Wet Weather On Existing Wet Surface...?
Asked by: Dexies
Thanks for your question. Application in wet weather and/or onto wet surfaces should be avoided. Thompson's Emergency Roof Seal would be more suitable for such applications.
