ARMOFLOOR CM4 is a water-based, three-part epoxy-cement floor screed developed specifically for application on humid or green concrete surfaces. It acts as a waterproofing barrier for subsequent epoxy, polyurethane, or acid-resistant coatings, with excellent adhesion even on damp or porous substrates. ARMOFLOOR CM4 can be applied up to 8 mm thickness, offering high early and final mechanical strength, outstanding chemical resistance, and shrinkage-compensated, easy application. It resists water, oil, and thermal stresses while maintaining compatibility with the expansion properties of concrete, making it ideal for anchoring coats and patching mortar on demanding horizontal surfaces.
