Cold storage facilities place demanding requirements on flooring. Exposure to low temperatures, moisture, temperature changes, heavy traffic and regular cleaning means the floor needs to maintain its performance in conditions that can quickly expose weaknesses in unsuitable materials. This is particularly important in food production, pharmaceutical, chemical and other industrial environments where hygiene and safe working conditions are also essential.
Polyurethane screed flooring can provide a practical solution for these demanding settings. When the correct system is selected and installed properly, polyurethane screed can offer resistance to low temperatures, impact, abrasion and moisture whilst providing a smooth surface that is straightforward to clean. It can also be specified with finishes designed to provide suitable slip resistance for areas where water or other liquids may be present. But why is polyurethane screed suitable for cold storage, and what should businesses consider before choosing a system?
Why Is Flooring Important in Cold Storage?
Flooring in a cold storage facility has to cope with far more than ordinary foot traffic. Depending on the application, it may be exposed to freezing temperatures, condensation, wash-down procedures, cleaning chemicals, forklifts, pallet trucks and heavy loads. A flooring system that isn’t suited to these conditions can deteriorate over time, potentially resulting in cracking, surface damage or areas that become more difficult to clean. For this reason, flooring should be considered as part of the wider design of the facility rather than simply as a finishing material. The chosen system needs to match the operating temperature, expected traffic, cleaning regime, chemical exposure, and condition of the existing substrate.
What Is Polyurethane Screed Flooring?
Polyurethane screed is a resin-based flooring system designed for demanding commercial and industrial environments. It is typically formed from polyurethane resin combined with aggregates and other components to create a hard-wearing surface. Once installed and cured, it provides a durable floor designed to withstand demanding use. Depending on the system selected, polyurethane screed can offer resistance to temperature changes, impact, abrasion, moisture and a range of commonly encountered chemicals. The exact performance of a polyurethane floor depends on the product specification, installation method and conditions within the facility. This is why professional assessment is important when selecting a system for a cold storage environment.
Can Polyurethane Screed Withstand Low Temperatures?
One of the main reasons polyurethane screed is considered for cold storage applications is its ability to perform in low-temperature environments. Cold rooms, chilled warehouses, and freezer areas can operate at temperatures well below those found in conventional commercial buildings. Flooring installed in these areas therefore needs to be specified with the operating conditions in mind. Suitable polyurethane screed systems can be designed to withstand low temperatures without losing the level of performance expected from an industrial floor. However, the exact temperature range will depend on the individual system, so it is important to select a product that has been specified for the conditions in which it will be used.
Temperature Fluctuations and Thermal Shock
Low temperatures aren’t the only challenge. Cold storage floors can also experience significant changes in temperature during cleaning, maintenance and changes in operating conditions. For example, a floor that is normally exposed to cold temperatures may subsequently be subjected to warmer water during a cleaning process. Repeated temperature changes can place stress on both the flooring and the substrate.
A suitable polyurethane screed system can be specified to cope with temperature cycling and thermal shock, helping reduce the risk of damage associated with repeated changes between cold operating conditions and warmer cleaning processes. The precise performance will depend on the system selected, which is why the intended cleaning regime and operating temperatures should be discussed during the specification stage.
Resistance to Heavy Traffic and Impact
Cold storage facilities can be extremely busy working environments. Staff may be moving between storage areas throughout the day whilst forklifts, pallet trucks, trolleys, and other equipment transport products around the facility. The floor therefore needs to withstand repeated mechanical traffic without quickly showing signs of wear. Polyurethane screed provides a robust surface that can be specified for areas exposed to heavy use, helping it cope with the demands of industrial environments.
Forklifts and Pallet Trucks
Wheeled equipment can place considerable pressure on flooring, particularly around turning points, loading areas and doorways. A properly specified polyurethane screed system can provide the strength and abrasion resistance required for these high-traffic zones. This makes it a useful option for cold stores where materials are regularly moved between refrigeration areas, loading bays and production spaces.
Everyday Wear and Abrasion
Constant movement can gradually wear down unsuitable flooring. Scratches, scuffs and surface deterioration can become more noticeable in areas where heavy equipment is used every day. Polyurethane screed is designed for demanding environments and can provide a hard-wearing surface capable of handling repeated use. This can help maintain the floor’s condition and reduce the need for frequent repairs.
Moisture and Chemical Resistance
Moisture is an unavoidable consideration in many cold storage environments. Condensation, spills, wash-down procedures and cleaning processes can all expose the floor to water. A properly specified polyurethane screed provides a highly resistant surface that can help protect the underlying substrate from moisture. Its smooth finish can also make liquid spills easier to clean and manage.
Chemical resistance is another consideration, particularly in food processing, pharmaceutical and industrial environments. Polyurethane flooring systems can provide resistance to a range of commonly encountered substances, although performance varies between products. If a facility regularly handles specific chemicals, those substances should be identified before installation so that the appropriate flooring system can be selected.
Hygiene and Easy Cleaning
Hygiene is particularly important in food storage and processing environments, but it also matters in pharmaceutical and other controlled settings. A smooth, seamless flooring system can make cleaning and maintenance more straightforward by reducing the number of joints where dirt and contaminants can accumulate.
Polyurethane screed can also provide a sealed surface that is easier to wash and maintain than damaged or heavily jointed flooring. This can support regular cleaning routines and help facilities maintain appropriate hygiene standards. The cleaning products and methods used should always be compatible with the flooring system, particularly where aggressive chemicals or high-temperature wash-down procedures are involved.
Slip Resistance and Workplace Safety
Cold storage environments can become wet, particularly around entrances, loading areas, cleaning zones and locations where condensation occurs. This makes slip resistance an important consideration when selecting flooring. Polyurethane screed systems can be specified with different surface finishes to provide an appropriate level of slip resistance for the intended environment. The right finish will depend on factors such as the amount of moisture present, cleaning methods, footwear and the type of work carried out in the area. Rather than selecting a finish based purely on appearance, these practical conditions should be assessed before installation.
Jointless Flooring for Cold Storage Areas
One of the practical advantages of resin flooring systems is the ability to create a continuous surface across large areas. Reducing unnecessary joints can make the floor easier to clean and can contribute to a more uniform finish. Proper detailing around walls, drains, thresholds and other interfaces remains important, however, particularly in environments where hygiene and moisture management are priorities. Professional installation is therefore essential to ensure that the flooring system and its associated details are suitable for the conditions.
How Is Polyurethane Screed Flooring Installed?
Installing polyurethane screed is a specialist process, and preparation is just as important as the application itself.
-
Assessing and Preparing the Substrate
Before installation begins, the existing floor should be assessed to determine whether it is suitable for the proposed system. Preparation may involve mechanical preparation, cleaning, repairs, removal of unsuitable coatings and other work required to create a suitable surface. Moisture levels may also need to be assessed depending on the substrate and flooring system. Thorough preparation helps provide the conditions needed for good adhesion and long-term performance.
-
Applying the Flooring System
Once the substrate has been prepared, the polyurethane components are mixed and applied according to the manufacturer’s specification. The flooring is installed to the required thickness and finish, with particular attention paid to edges, joints, drains and other details. The exact installation method will depend on the polyurethane system selected and the requirements of the facility.
-
Curing and Final Inspection
The flooring then needs sufficient time to cure before it is exposed to normal traffic and operating conditions. Curing times vary between products and installation conditions, so the manufacturer’s requirements should always be followed rather than relying on a generic timeframe. Before the area is returned to service, the finished floor should be inspected to ensure the installation meets the required specification.
Where Can Polyurethane Screed Be Used?
Polyurethane screed is suitable for a wide range of demanding environments where the floor needs to withstand heavy use, moisture and regular cleaning. In cold storage settings, potential applications include:
- Chilled storage areas.
- Freezer rooms.
- Food production areas.
- Cold preparation rooms.
- Loading and distribution areas.
- Refrigerated warehouses.
- Pharmaceutical storage environments.
- Processing and manufacturing facilities.
The suitability of a particular system will depend on the temperature, traffic, cleaning regime, and other conditions within the area.
