# Combimix CM 920 Industrial

Skip to content SKU: 10405 Type: Combimix Tags: high-traffic concrete leveling , industrial floor underlayment , pumpable self-leveling compound Combimix® CM 920 Industrial Pumpable Self-Leveling Compound CM 920 Industrial is a pumpable, durable self-leveling underlayment designed for use on concrete substrates. It can be used as a wear surface in industrial environments or as a base layer beneath epoxy, polyurethane, or traffic coatings. With its high strength, excellent wear resistance, and fast set time, CM 920 provides a smooth, reliable surface for demanding projects. Description Recommended Usage Substrate Requirements Packaging Data Sheets Description CM 920 is formulated for industrial-grade performance and use in high-traffic areas. It offers very high wear resistance, strong adhesion to properly primed concrete, and flexibility for use as both a direct wear surface and as a base for coatings. Suitable for indoor use on concrete substrates Can serve as a finished wear surface in industrial environments or as an underlayment for epoxy and polyurethane coatings Pumpable for efficient large-area application High compressive strength (average 5200 psi) and flexural strength (average 1450 psi) Very high resistance to wear and water damage resistant Fire classification A1fl Working time: 15–25 minutes at 70 °F Final set in 1–3 hours; coverable with tile after 12 hours Paintable with epoxy or similar coatings after 3–5 days Recommended Usage Approved for use on properly prepared concrete substrates in: Industrial floors requiring a wear surface Self-leveling base under epoxy, polyurethane, or traffic coatings Environments requiring high strength and very high wear resistance Substrate Requirements Clean, structurally sound concrete with an open surface to properly receive primer and allow for maximum adhesion RH ≤ 95% before pouring Must be primed with PP 600 before application Recommended ambient temperature: 50–80 °F (not below 50 °F) Packaging 44 lb bags and big bags Shelf life: 6 months unopened, stored dry on plastic-coated pallets Data Sheets Technical Data Sheet Related products Combimix® FF 830 Combimix® CM 960 Industrial Super Top Combimix® CM 760 Fiber Combimix® BetongSpackel
