PU Flooring

What Is PU Flooring?

PU flooring refers to flooring systems made from polyurethane resin — a synthetic polymer known for its flexibility, chemical resistance, and thermal stability. When applied as a flooring material, it forms a seamless, non-porous, and tough surface that can withstand heavy traffic, impact, temperature changes, and aggressive cleaning processes.

Unlike basic concrete or tiles, PU flooring provides:

• Excellent chemical and thermal resistance
• Flexible and durable surfaces
• Seamless finish for hygiene-sensitive areas
• Slip resistance in wet or dry conditions

Because of these advantages, PU flooring is now a preferred choice in various industrial and commercial sectors across Pakistan.

Types of PU Flooring Systems

There are several types of polyurethane flooring systems, each designed for specific performance needs. Understanding them will help you choose the right one for your facility.

1. PU Coating (Thin Film System)

A thin layer of polyurethane resin applied over prepared concrete or another floor system.
Use: Light-duty commercial areas, offices, showrooms.
Pros: Cost-effective, smooth finish, aesthetic appeal.
Cons: Not suitable for heavy traffic or impact.

2. PU Self-Leveling Flooring

This system creates a smooth, seamless floor with a thickness of 2–5 mm. It levels itself naturally, producing a clean, uniform surface.
Use: Food & beverage plants, warehouses, cold rooms, hospitals.
Pros: Excellent chemical resistance, easy cleaning, hygienic.
Cons: Medium durability; heavy impacts require thicker coatings.

3. PU Screed Flooring (Heavy Duty PU)

A trowel-applied flooring system typically 6–9 mm thick, designed for industrial-grade durability. It can resist extreme temperatures, aggressive cleaning, and heavy mechanical loads.
Use: Cold storage facilities, food processing units, beverage plants, chemical plants, factories.
Pros: Exceptional durability, impact and chemical resistance, thermal shock resistance.
Cons: Higher cost; requires expert installation.

4. PU Hybrid Systems (PU + Cementitious / Epoxy)

These combine the properties of polyurethane with other materials (epoxy or cementitious screeds) to provide specific performance, like enhanced moisture tolerance or flexibility.
Use: Production areas, heavy-duty environments.
Pros: Strong adhesion, flexibility, multi-functional performance.
Cons: Specialized system requiring skilled applicators.

Key Advantages of PU Flooring

1. Thermal Shock Resistance

One of the biggest advantages of PU flooring over epoxy is its ability to withstand sudden temperature changes. It performs well in hot water washdown and cold storage environments — ideal for food processing and cold chain logistics in Pakistan.

2. Chemical Resistance

PU flooring is resistant to most acids, alkalis, fats, oils, and cleaning agents, making it ideal for pharmaceutical and chemical industries.

3. High Impact & Abrasion Resistance

Its flexible yet tough structure absorbs impact without cracking, even in high-traffic areas like manufacturing floors or warehouses.

5. Hygienic & Seamless Finish

PU floors have no joints or grout lines, minimizing bacteria growth. This makes them ideal for hygiene-sensitive industries like food, beverage, and pharmaceuticals.

6. Durability

PU floors can last 15–20 years with proper installation and maintenance, making them cost-effective in the long run.

7. Fast Installation & Low Downtime

Certain PU systems can cure faster than traditional floors, allowing businesses to resume operations quickly.

4. Slip Resistance

Textured PU finishes provide excellent slip resistance, ensuring a safer work environment, particularly in wet or greasy zones.

Applications of PU Flooring in Pakistan

PU flooring is extremely versatile. Here are the most common applications:

1. Food & Beverage Industry

• Dairy plants, meat processing, bakeries, beverage plants
• PU flooring withstands hot water washdowns and aggressive cleaning chemicals.
• Provides slip resistance and hygiene compliance.

2. Cold Storage & Refrigeration Facilities

• Performs well in sub-zero temperatures.
• Resistant to thermal shock and cracking.

3. Pharmaceutical & Healthcare

• Seamless surface prevents contamination.
• Easy to clean and maintain.
• Compatible with cleanroom requirements.

4. Chemical & Manufacturing Plants

• Excellent resistance to corrosive chemicals.
• Withstands heavy traffic from forklifts and machinery.

5. Warehouses & Logistics Centers

• Durable and impact-resistant.
• Easy to maintain even under continuous movement of goods.

6. Automotive Workshops & Showrooms

• Resistant to oils, greases, and chemicals.
• Aesthetic appeal with functional performance.

7. Commercial & Public Buildings

PU coatings are increasingly used in airports, shopping malls, and exhibition halls due to their smooth finish and durability.

Step-by-Step PU Flooring Installation Process

Installing PU flooring correctly is crucial for its performance and lifespan. Below is the typical installation process used by professional contractors in Pakistan.

1. Surface Preparation

• Shot blasting or diamond grinding to remove dust, laitance, and weak layers.
• Remove oil or grease contamination.
• Repair cracks and joints.
• Moisture testing (very important in Pakistan due to humidity).

2. Priming

• Apply PU primer to seal the substrate and improve adhesion.
• Moisture-tolerant primers may be used for damp concrete.

3. PU Base Coat / Screed

• Pour or trowel the PU base layer according to system thickness.
• For self-leveling, the material spreads evenly to create a smooth surface.
• For screed, trowel application provides more durability.

4. Topcoat & Finishing

• Apply topcoat for UV resistance, slip resistance, and durability.
• Add decorative flakes or textures if required.
• Allow proper curing time before traffic.

5. Quality Testing

• Check for adhesion, surface finish, and thickness.
• Test slip resistance and flatness for compliance.

Pro Tip: PU flooring installation should be done by certified contractors with experience in industrial flooring. Poor surface preparation is the number one cause of failure.

Maintenance of PU Flooring

Proper maintenance can extend the life of PU flooring significantly.

• Daily: Sweep or vacuum to remove dust and debris.
• Weekly: Wet mop with neutral pH detergent.
• Monthly: Inspect for cracks, discoloration, or chemical damage.
• Annually: Reseal if needed, particularly in high-traffic or chemically exposed areas.

Maintenance Tips:

• Avoid harsh acidic or solvent cleaners unless approved by the manufacturer.
• Repair damage promptly to prevent further wear.
• Use floor mats in entrance areas to minimize dirt ingress.
• Plan regular professional inspections for large industrial sites.

Cost of PU Flooring in Pakistan

The cost of PU flooring in Pakistan can vary depending on several factors:

Approximate price range (2025)

• PU coating: PKR 400 – 700 per sq. ft.
• PU self-leveling: PKR 700 – 1,200 per sq. ft.
• PU screed (heavy duty): PKR 1,200 – 2,000+ per sq. ft.

(Prices are indicative and can vary based on site conditions and system specifications.)

Common PU Flooring Problems in Pakistan & Solutions

1. Bubbling or Blistering

• Cause: Moisture in substrate, poor priming.
• Solution: Proper moisture testing, moisture-tolerant primers, correct application.

2. Cracking

• Cause: Substrate movement or thermal stress.
• Solution: Use flexible PU systems and expansion joints.

3. Delamination

• Cause: Improper surface preparation or contaminated substrate.
• Solution: Re-grind, clean, and reapply with proper adhesion.

4. Discoloration

• Cause: UV exposure on non-UV-stable PU.
• Solution: Use aliphatic PU topcoat or UV-resistant sealers.

5. Chemical Staining

• Cause: Aggressive chemicals not compatible with system.
• Solution: Use high chemical-resistant PU or secondary protection layer.

Sustainability and Environmental Benefits

PU flooring contributes positively to environmental goals:

• Low VOC content: Many modern PU systems are solvent-free and low in volatile organic compounds.
• Long lifespan: Reduced waste from fewer replacements.
• Hygienic: Reduces the need for harsh chemical cleaners.
• Energy-efficient cleaning: Smooth surface lowers water and detergent use.

This makes PU flooring a sustainable and environmentally responsible flooring option for industrial and commercial buildings in Pakistan.

Choosing the Right PU Flooring Contractor in Pakistan

Selecting a qualified contractor is as important as choosing the right flooring system.

What to Look For:

• Proven experience in PU flooring projects.
• Manufacturer certification or partnerships.
• References from industrial clients.
• Clear warranty terms and maintenance guidance.
• Ability to conduct substrate testing.

Top tip: Don’t choose solely on the lowest price. Poor workmanship can lead to expensive failures and downtime.
