Gripset 4858 15 Litres Wet Area Membrane
Gripset 4858 is a fibre reinforced, single part liquid rubber membrane with unique colour changing technology designed for waterproofing wet areas, showers, laundries on concrete slabs and general structures that will be covered over with toppings, tile beds or overlay finishes.
Compliant to AS/NZS 4858:2004, Gripset 4858 satisfies the requirements of AS3740 “Waterproofing Wet Areas in Residential Buildings”.
Developed by advanced polymer technology, 4858 is flexible and elastomeric, displaying excellent waterproofing features with low water vapour transmission properties and the ability to withstand wet conditions without re-emulsification of the cured membrane.
