Description
Duram Azcothane is a water-based, highly flexible, high performance, polyurethane fortified acrylic emulsion waterproofing membrane formulated for use is demanding exposed, under tile, underground and immersed waterproofing applications. Duram Azcothane’s formulation complies with AS4858:2004 Appendix A: Durability of Waterproof Membrane and is generally applied in accordance with AS3740:2010/AS4654-2012 for external above ground use and meets the ‘Green Star’ environmental criteria. It is liquid applied and cures to form a durable, flexible, strong, uv resistant, odourless, seamless, and impervious waterproofing membrane. It does not re-emulsify after it has fully cured making it ideal for long-term waterproofing. It will not stain grout or tiles.
Uses
Duram Azcothane has been specifically designed for exposed, under-tile, underground and immersed waterproofing requirements included the long-term waterproofing of:
- Exposed concrete and metal roofs
- Wet areas within buildings (shower recesses, bathrooms & laundries)
- Ponds & water features
- Concrete and timber decks
- Terraces and balconies (under tiles)
- Concrete slabs
- Retaining walls
- Planter boxes
- Water retaining structures
- Tiles or topped areas
Suitable Surfaces
Duram Azcothane is suitable for properly primed: Concrete, cement, cement render, block work, brick, masonry, FC sheeting and CFC sheeting, plaster board and timber, plywood and particle board (if primed with Duram Primeseal) and metal (if primed with a metal primer).
Note: We do not regard particle board as a suitable substrate for wet areas and if possible should be replaced or covered with CFC sheeting – particularly in shower recesses. If covered we recommend that the particle board be coated with 2 coats of Duram Primeseal and joins and corners sealed with a polyurethane sealant prior to laying the CFC sheeting. Duram Azcothane may be applied to slightly damp surfaces but the product will not fully cure if the surface remains damp. This process takes longer than if the surface was allowed to dry before application. The surface must dry before the membrane can dry. Freedom from surface water, continual dampness is essential.
