RIW Toughseal Applications


Johns of Nottingham are specialist applicators of RIW Toughseal. 

This year we will be applying between 10,000 and 20,000m2 of RIW Toughseal to Plant Rooms, Bunds in Bunded Areas, Shower Rooms, Changing Rooms, Shafts, Risers etc. We apply RIW solvent free, which is a polymer modified, colour coded coating that provides an epoxy paint applied liquid DPM system.

We find it is typically used to provide a water and water vapour proof barrier in areas that require excellent tensile adhesion, chemical resistance and abrasion resistance, such as plant rooms and under raised access floors.   RIW Toughseal epoxy DPM system has a Class 1 fire rating and is UV resistant. 

We feel that "Remember its Waterproof" is an apt name for this trusted brand we love to use especially with the knowledge that its tried and tested and has a manufacturers guarantee (warrantee) "for the life of the structure".  Thats a quality you can trust in.
