Param 4500 is Portland cement-based, self-leveling concrete underlayment formulated to level and smooth interior concrete, terrazzo, ceramic and quarry tile, metal, wooden substrates, and non-water soluble adhesive residue on concrete prior to the installation of the finished flooring. It can be installed on, above, or below grade. Param 4500 provides a durable, flat, smooth floor surface with minimum labor and installation time.

Param 4500 provides a substrate that can accept ceramic tile and natural stone within 3-4 hours after application. Finished floor coverings such as concrete micro-toppings/overlays, resinous flooring, carpet, VCT, sheet vinyl, rubber, and engineered wood plank can be installed after 24 hours.
