AT-929 Moisture Cured Polyurethane
AT-929 is a High performance, tough, flexible, class 111 polyurethane waterproofing
membrane that meets the requirements of AS3740 by conforming to AS/NZS 4858
“wet area membranes”, for internal and external under tile areas.
At-929 is a single-component polyurethane liquid which cures by reaction with
atmospheric moisture to give a tough elastomeric waterproof membrane. It is
supplied as a thixotropic liquid which is easily applied at the recommended thickness
to both vertical and horizontal surfaces.
The high elasticity, excellent bond and low water permeability of AT-929 make it
ideal for a wide range of applications such as foundations, basements, ground floors,
suspended slabs, roof terraces, balconies, patios, planter boxes, inspection pits, roofs,
bathrooms and wet areas.
As a waterproofing membrane to internal and external wet areas that are to be
covered by tiling system laid on screeds that provide positive screeds to drainage
outlets and complying with the Guide to the installation of ceramic tiles – AS3958.1.
