Duram Azcothane is a high-performance water-based polyurethane dispersion fortified acrylic hybrid waterproofing membrane. It is designed for demanding applications such as exposed, under tile, underground, and immersed waterproofing. Azcothane meets various industry standards and criteria, including wet area membranes, external above-ground use, resistance to ultraviolet, and environmental criteria.
Azcothane is suitable for a wide range of surfaces, including concrete, cement and cement render, FC and CFC sheeting, block & brickwork, masonry/stone, FC, CFC, asbestos and Blue board sheeting, particle board, Scyon & composite sheeting, acrylic coatings, vitreous, ceramic & terra cotta tiles, bitumen (when primed with Duram Primeseal MC), metal (when primed with Duram ME Primer), timber, particle board, plywood (when primed with Duram Primeseal MC), masonite, plasterboard, extruded foam, and fibreglass/gelcoat/PVC. Duram provides recommended priming methods for these surfaces.
Coverage rates may vary depending on the type, condition, porosity, texture of the surface, and application technique. The minimum coverage rate is 1.7L/m² or 0.85L/m² per coat. A 15 Lt pail will cover 18 m² for 1 coat at 0.5mm DFT. For water-resistant non-tanking walls, the minimum coverage is 0.85L/m² at 0.5mm DFT. The dry film thickness of the membrane on floors and tanking areas should be 1.0mm DFT with each coat being 500 microns dry film (0.5mm DFT).
Drying and curing times are affected by the type, dryness, and porosity of the surface, temperature, humidity, ventilation, climate conditions, and application technique. As a guide, at 25ºC and 50% RH, the touch dry time is 2 to 4 hours per coat, set time is 12 hours, and full cure time is 24 hours per coat. Ensure the membrane is fully cured before tiling or topping. Azcothane is generally touch dry within 2 to 4 hours and fully cured after 24 hours. Recoat between 4-24 hours.
Avoid spills. Wet spills can be cleaned with water, but they may be difficult to clean on porous surfaces. On concrete and non-porous surfaces, use a cloth and water for wet spills. Do not clean off carpets as it is better to allow the product to cure and then shave the carpet. Equipment should be immediately cleaned with water.
Store Azcothane in a cool, dry place away from heat and freezing. The product is not flammable. It is available in 4 Lt and 15 Lt pails, with 15 liters equating to 16 kg. Shelf life is 12 months in an unopened container.
