Product Introduction

Heavy-duty polyurethane cement flooring combines a water-dispersed polyurethane binder with cementitious components, pigments and graded aggregate. Its coefficient of thermal expansion is closer to concrete than a conventional resin coating, helping the system remain bonded during repeated hot-water cleaning and cold-service cycles. The 6–9 mm screed provides deep mechanical protection and a textured, liquid-impermeable finish for demanding wet production. Properly formed falls, coves, drain edges and retained structural joints complete the hygienic floor envelope.

Key Features

The polyurethane-cement hybrid tolerates wider service-temperature changes than conventional thin resin coatings.

A thick aggregate structure absorbs impact and abrasion from pallets, racks and mobile processing equipment.

Textured finishes maintain practical traction where water, detergent or process residue may reach the floor.

Monolithic coves and detailed drain interfaces reduce vulnerable grout lines in frequent washdown areas.

Customer Product Concerns

Wet process floors face thermal shock, aggressive sanitation, impact and standing liquid at the same time, which can overwhelm a thin decorative coating.

Hot wash water causes a rigid coating to crack or debond from cool concrete.The polyurethane-cement matrix moves more compatibly with concrete through repeated thermal cycling.

Dropped tools and loaded pallet wheels break through a thin resin layer.A 6–9 mm aggregate-rich screed provides deeper impact and abrasion capacity.

Smooth flooring becomes hazardous during foaming and rinse-down.Selected broadcast aggregate creates a defined wet-area traction profile without open tile joints.

Water enters around drains and cove junctions, then attacks the bond from below.Rebated drain edges, integral coves and sealed penetrations continue the polyurethane cement system through critical details.
