  1. 1. Surface PreparationSurface Preparation for Waterproofing Surface must be structurally sound Cracking or movement of the substrate after a membrane has been installed is likely to cause the membrane to fracture. Treat cracks and movement joints Cracks, construction joints, expansion joints and other mobile joints should be treated in accordance with the membrane manufacturers recommendations. Clean and free from any contaminant materials A membranes bond will fail at its weakest point so if applied over dust, loose materials or poorly bonded contaminants it will fail prematurely. Repair any holes/voids in the substrate A uniform thickness membrane is very difficult to achieve over holes/voids. Remove any protrusions and sharp edges A uniform thickness membrane is very difficult to achieve over protrusions or sharp edges.
  2. 2. Surface PreparationSurface Preparation for Waterproofing Concrete should be aged for 28 days and screeds should be aged for 7 days Cementitious surfaces can develop plastic shrinkage cracks during initial curing which must be totally formed before the membrane is applied. Time must also be allowed for the development of efflorescence which must be removed before the membrane application. Ensure substrate is dry (5% moisture or less) High substrate moisture content will form blisters in the membrane during curing. Seal wet or freshly laid concrete with ARDEX WPM 300 Allow to cure overnight. Provides a concrete curing membrane and barrier coat.
  3. 3. Surface PreparationPriming for Waterproofing Porous surfaces are primed to consolidate residual dust and reduce the porosity of the substrate to avoid excessively fast interface drying and blistering of the membrane Wet or fresh concrete, PVC and metal are primed to provide a barrier between the substrate and the membrane All cementitious substrates should be primed with ARDEX WPM 265 Water Based Primer at a rate of 6m2/L Highly porous substrates may require 2 coats PVC should be primed with pink plumbers primer Metal surfaces should be primed with a two pack epoxy zinc phosphate primer If moisture content is too high or concrete is freshly laid, use ARDEX WPM 300 water based epoxy as a barrier coating Allow primer to dry prior to waterproofing
