Cementitious Polyurethane Flooring | Food-Grade Floors

What is Cementitious Polyurethane Flooring?

Cementitious polyurethane (CPU) flooring is a hybrid system that combines the durability of cement with the flexibility and chemical resistance of polyurethane resin.

This innovative flooring technology creates a seamless, hygienic surface specifically engineered for food processing, beverage production, and other facilities requiring USDA/FDA compliance. The cementitious base provides excellent thermal shock resistance, while the polyurethane component offers superior chemical resistance and flexibility.

CPU flooring is the preferred choice for facilities that experience extreme temperature fluctuations, require frequent washdowns with hot water and chemicals, and must maintain the highest hygiene standards to prevent bacterial growth and contamination.

Key Benefits

Why cementitious PU is ideal for food-grade facilities

???

Thermal Shock Resistance

Withstands extreme temperature changes from -40�C to +120�C without cracking. Perfect for areas with hot washdowns and cold storage transitions.

?

USDA/FDA Compliant

Meets all USDA and FDA requirements for food contact surfaces. Certified for use in meat, poultry, dairy, and beverage processing facilities.

??

Anti-Microbial Surface

Seamless, non-porous surface prevents bacterial growth and harboring. Easy to sanitize and maintain strict hygiene protocols.

??

Slip Resistance

Textured finish provides excellent traction even when wet. Reduces workplace accidents in frequently washed areas.

??

Chemical Resistance

Resists acids, alkalis, fats, oils, and aggressive cleaning chemicals used in food processing sanitation protocols.

??

Impact Resistant

Durable cement-based matrix withstands heavy equipment, dropped tools, and high-impact operations without damage.

Installation Process

Professional installation for food-grade environments

1

Surface Preparation

Shot blasting or grinding to achieve CSP 3-4 profile. Remove all contaminants, oils, and weak concrete. Ensure proper drainage slope.

2

Moisture Testing

Conduct calcium chloride tests to ensure substrate moisture levels are within acceptable limits (typically <4% RH).

3

Primer Application

Apply moisture-tolerant epoxy primer to seal concrete and enhance adhesion. Allow proper curing before next layer.

4

Base Layer Installation

Trowel-apply cementitious PU base coat to specified thickness. Create proper slopes for drainage and incorporate cove bases.

5

Texture & Seal Coat

Apply textured top coat for slip resistance. Seal with polyurethane coating for enhanced chemical resistance and easy cleaning.

6

Quality Assurance

Comprehensive inspection, thermal shock testing, and documentation. Provide USDA compliance certificates and maintenance protocols.

Frequently Asked Questions

What makes cementitious PU different from regular epoxy?

Cementitious PU combines cement's thermal shock resistance with polyurethane's chemical resistance and flexibility. Unlike epoxy, it can withstand extreme temperature changes (-40�C to +120�C) without cracking, making it ideal for hot washdown areas and cold storage transitions.

Is this flooring required for USDA inspections?

While USDA doesn't mandate specific flooring types, they require floors to be impervious, easy to clean, and resistant to moisture. Cementitious PU meets all these requirements and is pre-approved by USDA for meat, poultry, and dairy facilities, simplifying inspection processes.

How does it handle hot water washdowns?

Cementitious PU is specifically designed for frequent hot water washdowns. It can handle boiling water (100�C+) multiple times daily without degradation. The thermal shock resistance prevents cracking that occurs with standard epoxy systems.

What is the expected lifespan in food processing facilities?

With proper installation and maintenance, cementitious PU flooring typically lasts 15-20 years in food processing environments. High-traffic areas may require recoating every 10-12 years depending on usage intensity and cleaning protocols.

Can it be installed in cold storage freezers?

Yes, cementitious PU is excellent for cold storage and freezer applications. It maintains flexibility and adhesion at temperatures as low as -40�C and can handle the thermal shock when moving between freezer and ambient temperatures.
