This system will need to be applied to a ‘slurry’ prime coat of Emer-Proof Multi-Purpose Primer and Additive, mixed with sand and cement – see priming instruction below. Approximate total 1.5L/m² (for non-immersed coverage: applications) Approximate total coverage: 2L/m² (for immersed applications) Wet Film Thickness 1.5mm (for non-immersed applications) Dry Film Thickness 1.5mm (for non-immersed applications) Wet Film Thickness 2mm (for immersed applications) Dry Film Thickness 2mm (for immersed applications) Specification Clause Where so designated on the drawings, surfaces shall have a low VOC, liquid applied, water based, fast drying, flexible two component, polymer modified cementitious waterproofing membrane applied. The membrane shall be Emer-Proof Quick Dry Two Part. Areas shall be prepared and the membrane applied in accordance with the current Emer-Proof Quick Dry Two Part Technical Data Sheet. Design Criteria Emer-Proof Quick Dry Two Part is designed to be applied by brush, roller or spray. In general wet area applications Emer-Proof Quick Dry Two Part is applied as two (2) coats with a minimum WFT of 1.5mm (coverage of 1.5 litres/m²) resulting in a minimum DFT of 1.5mm. For permanently wet or submersed conditions Emer-Proof Quick Dry Two Part is to be applied as three (3) coats with a minimum with a minimum WFT of 2.0mm (coverage of 2.0 litres/ m²) resulting in a minimum DFT of 2.0mm. Application Instructions Surface preparation All new concrete surfaces must be allowed to cure for at least 7 days and have a wood float finish. Steel trowelled finished slabs must be chemically or mechanically abraded prior to commencing waterproofing. Rendered surfaces must be allowed to cure for at least 16 hours in normal ambient conditions prior to commencing waterproofing. Ensure all rendered surfaces have a wood float finish. All screw / nail heads must be sealed with Emer-Seal MS sealant and all sheet joints must be covered with Emer- Proof Elastic Joint Band Tape. See Emer-Proof Elastic Joint Band System technical data sheet. Ensure all surfaces are sound, dry and free from excessive movement, oil, dust, grease, wax, curing compounds, release agents, paint and any other loose contaminants. Also remove any protrusions from the surface that may pierce the membrane. Priming Substrates must be primed, prior to the application of Emer-Proof Quick Dry Two Part. Primer choice is defined by substrate requirements: ‡ For porous masonry surfaces, Emer-Proof Multi-Purpose Primer and Additive may be selected (see TDS for further details) ‡ For non-porous substrates, such as ceramic tile, metals and plastics, Emer-Proof Non-Porous Primer may be selected (see TDS for further details) ‡ For submerged applications such as ponds, pools and water retaining structures, a slurry primer ‘must’ be used ‡ Forming a waterproof and high bonding slurry coat - mix the following parts by volume: 1 part Primer + 1-1.5 parts of Portland cement + 0.5 -1.0 parts sand. Once mixed to a brushable consistency, apply to substrate with a brush, broom etc. When applying Emer-Proof Quick Dry Two Part over this slurry, optimum adhesion results are achieved as a “wet on wet’ application. Damp surfaces - entrapped moisture Seek technical advice from Parchem. Cracks Cracks larger than 2 mm or structural shrinkage cracks must be firstly cleaned and any loose material removed then filled with Emer-Seal MS sealant or covered with Emer- Proof Elastic Joint Band Tape. See Emer-Proof Elastic Joint Band System technical data sheet. Emer-Proof Elastic Joint Band Tape, Corners and Detailing Accessories The Emer-Proof Elastic Joint Band System has been specifically developed by Parchem as a superior bond breaker system to traditional sealants and bond breaker tapes. The Emer-Proof Elastic Joint Band System includes tape (for change of direction – such as wall/wall and wall/floor joints etc.), both 270o external and 90o internal corners, an adjustable internal corner as well as three (3) size variations on pipe detailing squares (suitable from 6mm > 150mm pipe diameters). Parchem also incorporate a fully fleeced, self-adhesive butyl rubber floor waste detailing collar that is suitable for all wet area leak control flanges, for optimum sealing capabilities. If being used in tanking and waterproofing applications, the Emer-Proof Quick Dry Two Part requires a suitable bond Emer-Proof® Quick Dry Two Part
