DENARE WATERPROOFING TECHNOLOGIES AUSTRALIA LIQUID MEMBRANES ELASTO-DECK BT A COALTAR FREE ELASTOMERIC WATERPROOFING SYSTEM ELASTO-DECK BT is a black, liquid applied single-component moisture-cured polyurethane coating, designed to form a seamless, flexible rubber membrane impervious to moisture. It is suitable for use in showers, balconies and other wet areas as described in Australian Standard AS3740-2004 - "Waterproofing Wet areas within Residential Buildings." ELASTO-DECK BT, once cured, allows contraction and expansion over a broad temperature range and maintains waterproofing properties under continuous exposure to water. ELASTO-DECK BT remains flexible from -20°C to 80°C. ELASTO-DECK BT waterproof membrane is intended for use wherever overflow water must be contained. TYPICAL USES ARE: Waterproofing in between concrete slabs, such as parking decks, roof decks or courtyard areas over subterranean parking. Waterproofing below grade exterior walls or foundations and basements or other structures that are to be backfilled Waterproofing under terrazzo or tiled floors. Waterproofing under wet areas including laundry and bathroom floors. Waterproofing inside of elevated swimming pools. Waterproofing of occupied areas under malls, plazas and promenades. Waterproofing of emergency water storage tanks for fire sprinklers. (ELASTO-DECK BT Reservoir Grade should be used for potable water.) ADVANTAGES: ELASTO-DECK BT is a single-component compound that may be used directly from the container with no mixing required. The addition of catalysts are not necessary, as ELASTO-DECK BT is a moisture cured compound. May be applied by spray equipment, brush, roller, squeegee or trowel, without the need for heating the material. May be applied over concrete, stone, brick, cement blocks, wood, metal, compressed sheeting and most other surfaces. ELASTO-DECK BT cuts cost of application by eliminating mixing, splicing, sealing tapes, adhesives and other labour consuming methods required when installing other convential types of waterproofing systems. The superior flexibility and elongation properties of ELASTO-DECK BT allows expansion and contraction with the substate, without cracking or becoming brittle. Does not contain any potentially hazardous coal tar. When fully cured ELASTO-DECK BT does not exhibit leaching or bleed through. When installed to the above specifications this system conforms to AS 3740-2004 ("Waterproofing of wet areas within residential buildings.") INSTALLATION DETAILS: Suitable substrates such as villa board, structaboard, plasterboard, concrete and cement render shall be dry, clean and free from dust, oil and other contaminates. All cracks over 1.0mm in width must be filled and covered with Denare Polyurethane sealant. Internal corners, penetrations and other details shall also receive a bead of Denare Polyurethane sealant. Floor wastes in concrete shall be cut to floor level with no up stands. Particle board or compressed sheet flooring should have leak control flanges fitted to allow water to drain down into floor waste.(These to be adhered not screwed or nailed). ELASTO-DECK BT is self priming on surfaces such as villa board, plasterboard, structafloor and sound concrete. Porous substrates should be filled or primed with ELASTO-DECK BT thinned with 20% Denare general purpose solvent. Where substrate has been subject to leakage or may be damp Denare Hydrepoxy 300 should be applied at the rate of 3-5m²/lt. This should be allowed to cure for at least 2 hours. PVC surfaces must be primed with Denare ETCH PRIMER ELASTO-DECK BT Type II may be used in a single application (1.2-1.5 litres per m²)on vertical surfaces. Application must be made uniformly to avoid thin spots and care must be taken to avoid pinholes and repair them should they occur. Coverage to obtain 1.25mm is 1.5lt/m². Where a two coat application is preferred, two coats at 0.75lt/m² per coat to be applied, allowing a 24 hour cure time between coats. A dry film thickness of 1.5mm is reccommended over horizontal surfaces and 1.00mm is reccommended on vertical surfaces. Protection board must be used prior to backfilling of pouring the concrete topping slab. Do not use polystyrene. ELASTO-DECK BT is compatible with most Solvent free tile adhesives. Careful selection of the adhesive best suited to the particular substrate, and strict compliance with the manufacture's instruction is essential. ELASTO-DECK BT can be repaired by cleaning the surface with a solvent wipe. Allow to flash off and recoat with ELASTO-DECK BT.
