# 2K Cold Polyurea Technical overview ## Cold-applied, seamless waterproofing beneath tile finishes Josoor supplies a two-component cold-applied polyurea membrane for waterproofing beneath tile finishes in internal or protected areas. In the documented build-up, a solvent-free epoxy primer bonds the prepared substrate to a smooth, continuous membrane layer for medium-duty service. ### Technical overview Material Two-component cold polyurea waterproofing membrane Application Cold-applied membrane over the prepared epoxy primer Documented substrates Concrete, screed and wood Substrate condition Sound, clean and dry; stated moisture range 0–4% System build-up Two-component solvent-free epoxy primer followed by the cold polyurea membrane Finish and duty Smooth, seamless membrane; medium-duty protected service ### Where this applies: - Waterproofing beneath tile finishes in internal areas. - Protected under-tile installations requiring a flexible, joint-free barrier. - Prepared concrete, screed and wood substrates within the documented system. Do not apply directly to unprimed cementitious substrates. Check tile-adhesive compatibility and observe the recoat window; light abrasion may be needed if it is exceeded. Aromatic polyurea can chalk or yellow outdoors, so this protected-area system is not presented as an exposed UV-stable finish. Send your substrate, area and tile-finish requirements for the membrane data sheet, primer specification and supply quotation.
