Concrete surfaces should be smooth, any imperfections, pinholes etc., are to be filled and the surface made smooth. Contact your local Parchem branch for suitable concrete repair products from our extensive range. Concrete must be cured for 28 days; sand / cement screeds need to be cured for 7 days. Surfaces must be dry, suitably prepared and in a sound state prior to beginning the application. Priming Substrates must be primed, prior to the application of a liquid waterproofing membrane system. Primer choice is defined by substrate requirements: „ For porous masonry surfaces, Emer-Proof Multi-Purpose INDEX 460 Primer and Additive may be selected (see TDS for further details) „ For non-porous substrates, such as 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 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 Ecoflex Anti Root 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. Application Ensure the surface has been appropriately prepared in accordance with this TDS. Emer-Proof Ecoflex Anti-Root may be applied with a roller (12 mm nap recommended), brush or standard airless sprayer (piston pump unit, 21 -25 thou tip size - thoroughly mix product before spraying). Its texture and non-sag formulation make it suitable for vertical and horizontal application. The Emer-Proof Elastic Joint Band System should be installed first. Apply the Emer-Proof liquid membrane across the substrate joins extending approximately 70mm either side of the join. Whilst the Emer-Proof liquid membrane is still in a wet state install the Emer-Proof Elastic Joint Band tape, corners and accessories ensuring that all air voids are expelled. Emer-Proof Elastic Joint Band Corners should be placed in first followed by the Emer-Proof Elastic Joint Band Tape. The Emer-Proof Elastic Joint Band tape, corners and pipe detailing squares can be joined via a 50mm overlap, sandwiching a small amount of Emer-Proof liquid membrane between the overlapping faces. Emer-Proof Ecoflex Anti-Root is laid onto the surface continually in one direction; it should not be brushed out. Brooms, brushes etc. should be regularly washed during the operation and at any breaks as follows: Keep available a container filled with sufficient strong detergent/water solution to fully cover the broom or brush. Soak the brush in the solution and shake out before use. As work progresses, rinse the brush at frequent intervals to prevent it clogging, and again shake out before resuming. Ensure the detergent is thoroughly washed out of the brush or broom with clean water before resuming. During any breaks in work the brushes should be left to soak in this solution. Each successive coat should be applied at 90 degrees to the previous coat. Allowing a drying time of 2-4 hours between coats. Conduct a final inspection on the surface of the membrane prior to commencing back-filling to ensure no pinholes exist. A further coat may be required if imperfections or pinholes are present in the membrane. Mixing Emer-Proof Ecoflex Anti Root membrane should be lightly stirred before using, and can be applied to both vertical and horizontal surfaces using a roller or brush. Emer-Proof®(FRÀH Anti-Root
