Ardex R3E Moisture Tolerant Epoxy Primer (Choice Of Size)

ARDEX R 3 E Solvent Free Epoxy Primer and Bonding Agent is a two-component, solvent-free, epoxy resin for use on sound concrete, cementitious surfaces, calcium sulphate-based screeds and smoothing compounds.

ARDEX R 3 E forms a primer/bonding layer on most dry substrates, especially smooth or dense surfaces in internal and external situations.

ARDEX R 3 E can be used as a primer and bonding bridge, prior to the application of the ARDEX range of Cement-Based Tiling and Flooring products, and on cementitious and Calcium Sulphate based screeds. ARDEX R 3 E must be sand blinded to refusal, with dry ARDEX FINE AGGREGATE to give a mechanical key for use as a primer prior to application of the ARDEX K 80/ARDEX SD-T B Industrial Floor System, or other appropriate ARDEX Cement-Based products and Smoothing Compounds.

Where substrates are very porous, more than one coat of ARDEX R 3 E may be required to saturate the surface and achieve the desired bonding efficiency. For applications where the relative humidity (RH) of the substrate is in excess of 75%, or where a structural Damp Proof Membrane is not installed, ARDEX DPM 1 C  should be used prior to applying ARDEX R 3 E.
