P-20 Polymer Cement

Epoxy Systems’s P-20 polymer cement is a heavy-duty smoothing and resurfacing product designed for all types of concrete structures. More resilient than standard concrete, P-20 is suitable as a grouting product under equipment and can be applied in thicknesses ranging from a feather edge to several inches thick. P-20 is easy to mix and apply, quick setting, odorless, and provides great adhesion to concrete while cleaning up easily with water. This product stands out for resurfacing concrete and rebuilding concrete beams, ceilings, and walls, excelling in vertical and overhead applications.

Applications & Properties

P-20 is a blend of specially-formulated cements (50-pound bag) and an acrylic copolymer (1 ¼ gallons). It is recommended for concrete floor repairs, vertical and overhead work, leveling rough surfaces, grouting under equipment, and other similar applications. Vertical and overhead surfaces can be repaired with applications of P-20 ranging from ¼” to ½” in thickness without forming, whereas floor and formed usage can be applied at any depth. For applications over ½” thickness, P-20 may be extended using up to 20 pounds of dry crushed stone or pea gravel.  Standard packaging is called a Bulk Unit which includes four 50# bags of powder cement and one five gallon pail of co-polymer liquid.
