A reinforced water borne polyurethane waterproof membrane will be applied in two coats over an appropriate primer for the substrate. The substrate is firstly cleaned of dirt and contaminants, primed and all joints caulked. The membrane is applied with roller and brush at a rate of 1.5kg per m2 over the two coats. Although already containing reinforcement fibres, the membrane is additionally reinforced with fibreglass mat on screeded shower recess floors and with polyester bandage at all other joints and corners. The membrane will extend over the full area of the floor in each room and turn up 70mm at the perimeters except in the shower enclosures where it will extend 1900mm approx. The membrane will be flashed down into floor wastes and will be applied 300mm above fixtures such as basins and sinks. Wherever possible we will waterproof around shower rose fittings and flick mixers. Waterstops will be provided under insert baths but waterstops at door thresholds will generally be left for the tiler to ‘sikaflex’ to the membrane. A dry membrane is not the same as a cured membrane and we recommend that a minimum 48 hours elapses from final coat to placing of tiles. Our membranes are compatible with under tile heating systems. If required we can install shower screeds or preformed shower bases prior to waterproofing. Note that AS 3740 has recently been updated because of a spike in the number of waterproofing failures in Australia and New Zealand. These failures are connected with the new trends in channel grates and also European style baths (without integral tiling beads). If you are unaware of the new standard please call us for advice prior to purchase or installation.
