Gripset C-Rubber is an economical, rubber-filled polymer-modified tile adhesive for internal and external wall and floor tiling. It combines C2TES1 performance, flexibility, non-slump properties and extended open time with a respirable-silica-free formulation, making it a practical choice for general trade tiling and wet-area work.
Compare tile adhesives: See our complete tile adhesive range from ARDEX, Gripset, Mapei and RLA to compare flexibility, setting speed, wet-area suitability and tile/substrate requirements.
Use with porcelain, ceramic and vitrified tiles, mosaics and non-moisture-sensitive natural stone. Suitable substrates include concrete, screeds and renders, blockwork, plasterboard linings, compressed fibre-cement sheeting and compatible Gripset waterproofing membranes.
Gripset lists a 30-minute open time, 40-minute adjustment time and approximately 1-hour pot life. Wet areas require the supplier-specified cure period before being placed into service.
C-Rubber is not positioned by Gripset as the immersed/pool option in this range; choose a supplier-approved immersed-area adhesive where that service is required. Do not use with moisture-sensitive stone. Follow the current Gripset technical data sheet and AS 3958.
Gripset system products: For substrate preparation, see Gripset GP Primer for porous surfaces and Gripset OP Primer for suitable dense or non-porous surfaces. For compatible wet-area systems, see Gripset 38FC Membrane.
