Wear-Surface Durability
Pumpable placement for consistent results on large projects.
Fast turnaround with walk-on times typically 1 to 3 hours and early cover times.
Industrial wear toppings that resist abrasion and rolling loads.
Fiber-reinforced options for added stability in thicker pours.
Interior and exterior solutions including a polishable, exterior-rated topping.
Coating-ready finishes that accept epoxy, polyurethane, polyurea, and acrylic systems.

Where It Excels

CombiMix systems are designed for fast-track floor preparation in interior projects where schedule, flatness, and finish readiness are critical. They are a strong fit for warehouses and logistics areas, production and light manufacturing spaces, retail back-of-house areas, office and commercial tenant improvements, education and healthcare renovations, and multifamily corridors and common areas. In these environments, the priority is a smooth, predictable substrate that installs efficiently and is engineered to receive downstream flooring or coating systems, rather than being treated as the final wear surface.

Installation Basics

STEP 1

Prep

Substrates must be clean, sound, and open for proper primer absorption. Maintain substrate and ambient temperatures within each product range.

STEP 2

Prime

Prime using the Formulated Materials primer specified on the product data sheet (APS Primer in most cases).

APS Primer

Place (pump or mix)

Observe recommended working times, set times, and cover times for the specified thickness.

STEP 4

Finish (de-air and smooth)

Follow the latest product data sheets and safety data sheets.

Combimix Helps You

Stand up To Traffic

Wear toppings deliver high surface durability and abrasion resistance for forklifts and heavy rolling loads.

Reduce Prep and Rework

Consistent pumpable placement, strong adhesion to properly primed concrete, and low shrinkage help avoid callbacks.

Cut Time and Cost

Fast set and early cover reduce downtime and labor per square foot on high-volume pours.

FAQs

Can I use Combimix as a wear surface?
Yes. CM 920 and CM 940 are indoor wear toppings. CM 960 is a premium wear topping for interior or exterior use. Seal or coat when specified. Ask your sales representative about achieving custom polishable finishes with CM920.

CM 750 S, CM 760 Fiber, and CM 780 Fiber Basic are self-leveling underlayments and must be covered by floor finishes or coatings.

Yes. Formulated Materials primer specified on the product data sheet (APS Primer in most cases).

Most systems are walkable in 1 to 3 hours and can be covered within 12 to 72 hours depending on product and thickness. Refer to the specific data sheet.

CM 960 can be ground, polished, and pigmented. Follow the CM 960 data sheet for timing and tooling.
