All screw / nail heads must be sealed with either Emer-Seal PU25 or PU40 sealant. All sheet joints must be covered with either Emer- Proof Elastic Joint Band Tape and associated detailing accessories if required (e.g. internal / external corners and pipe detailing collars) or Emer-Seal PU25/PU40 as mentioned under the heading Cracks). See Emer-Proof Elastic Joint Band System technical data sheet or Emer-Seal PU25 or PU40. Also remove any protrusions from the surface that may pierce the membrane. Priming Substrates must be primed, prior to the application of Emer-Proof Under Tile membrane: 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) Page 2 445 „ For non-porous substrates, such as Scyon sheeting, CFC, wet area timber, ceramic tile, metals and plastics, Emer-Proof Non-Porous Primer may be selected (see TDS for further details) Damp surfaces - entrapped moisture Seek technical advice from Parchem. Cracks Cracks larger than 2mm or structural shrinkage cracks must be firstly filled with a flexable polyurethane type sealant such as Emer-Seal PU 25 or PU40 and then a 50mm wide polyethylene tape placed over the crack prior to the application of Emer-Proof Under Tile. Alternatively the cracks can simply be covered with the Emer-Proof Elastic Joint Band Tape system. 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 270° external and 90° 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 waterproofing applications, the Emer-Proof Under Tile membrane requires a suitable bond breaker at all substrate junctions. Parchem nominates the Emer-Proof Elastic Joint Band System which includes tape, corners and pipe penetration detailing squares or equivalent bond breaking methods compliant with local waterproofing standards and building recommendations. If a sealant is required, Parchem nominate either Emer-Seal PU25 or Emer-Seal PU40 polyurethane sealants. Mixing Emer-Proof Under Tile membrane should be lightly stirred before using, and can be applied to both vertical and horizontal surfaces using a roller or brush. Membrane Application Ensure the surface has been appropriately prepared in accordance with the Parchem TDS. Install Emer-Proof Elastic Joint Band tape / corners and accessories (as per separate Emer-Proof Elastic Joint Band System Technical Data Sheet). Apply the first coat of Emer-Proof Under Tile to the primed surface using a thick brush or roller. After waiting the required 2 to 4 hours (@23°C) re-coat time, re-apply a second coat of Emer-Proof Under Tile at 90° to the first coat, ensuring complete coverage is achieved and no air bubbles exist. A third coat may be required if imperfections are present in the membrane. Conduct a final inspection on the surface of the membrane prior to commencing tiling to ensure no pin holes exist. Once the waterproofing is completed, do not disturb the area for at least 24 hours. Tiling can commence approximately 24 hours after last coat, in which case Emer-Proof Tilebond Flex tile adhesive should be used. Maintenance No special requirements, any damage identified during normal inspections should be repaired or replaced as appropriate. Limitations „ Emer-Proof Under Tile is not designed for use as a long term UV exposed membrane. „ Emer-Proof Under Tile should not be applied when surface temperatures are below 5°C or above 30°C Emer-Proof® Under Tile
