Frequently Asked Questions
Which Duram membrane suits a balcony or podium?
Azcothane Reo. It is an internally microfibre-reinforced acrylic hybrid meeting NCC requirements, so no separate reinforcing matting layer is needed on balconies, terraces, decks, and podiums.
What is the difference between Azcothane and Multithane?
Azcothane is water-based acrylic hybrid, easier cleanup and faster recoat. Multithane is polyurethane: tougher, for heavy-duty wet areas where abrasion and standing water demand it.
Do I need a primer under Duram membranes?
Usually yes on porous or chalky substrates. Duram S900 and the range's primers seal and key the surface; the membrane data sheet lists which primer pairs with which surface.
Is there a bituminous option for below-ground work?
Bituflex covers bituminous membrane work such as retaining walls and below-grade surfaces where rubberised bitumen remains the economical barrier. Match the product spec to the job conditions before you start.
Can Duram membranes be tiled over directly?
Cementitious grades accept tile adhesive once fully cured. Polyurethane and bituminous membranes need a compatible bonding bridge or screed first, per the data sheet. Always confirm cure state by the data sheet, not by touch alone.
What coverage does a litre give?
Coverage varies by product and substrate porosity, so check each data sheet. Two thin coats always outperform one thick coat for film consistency and cure.
