water-based, flexible, high performance, polyurethane fortified acrylic emulsion waterproofing membrane incorporating micro-fibres

Azcothane Reo is a water-based, flexible, high performance, polyurethane fortified acrylic emulsion waterproofing membrane incorporating micro-fibres and formulated for use is demanding exposed, under tile, underground and immersed waterproofing applications.
