PUSMSL – Self-Leading Polyurethane Screed

The PUSMSL system from UK Resin Floors functions as a self-levelling polyurethane cement screed which provides hygienic and chemical-resistant properties along with smooth surfaces for easy cleaning in specific environments. The 4–12 mm thick PUSMSL system unites cement strength with polyurethane flexibility to create a perfect liquid-tight floor surface which operates effectively in demanding industrial environments.

Key Features

The system produces a flat self-levelling surface which provides hygienic and efficient operation for different environments.
The system provides heavy-duty wear resistance which enables it to handle continuous traffic and mechanical stress.
The system shows resistance to chemicals and solvents which protects against acids and alkalis and oils and aggressive cleaning solutions.
The non-porous surface of this system creates a liquid-tight barrier which simplifies cleaning operations while preventing contamination.
The system maintains its integrity through thermal-shock resistance which allows it to handle hot water washdowns and steam and fast temperature fluctuations.
The system achieves rapid strength development which enables quick return to service operations with minimal downtime.

Technical Details

The system provides four different thickness options which range from 4 mm to 6 mm to 9 mm to 12 mm.
The application of PUCEM L primer serves to seal the substrate and enhance bonding between the substrate and the applied material.
The self-levelling system requires pouring and subsequent rolling to achieve a uniform finish.
The curing process requires about 10 hours to complete.
The surface presents a flat and seamless finish which provides hygienic and liquid-tight protection.

Application Process (Summary)

The application process starts with applying PUCEM L primer to the substrate for pore filling and better adhesion.
The mixture of A-component with pigment paste requires addition of B-component before blending.
The mixture requires 30 seconds of blending followed by filler addition until it reaches a smooth consistency.
The mixture should be distributed uniformly through the floor using a floor trowel.
A spiked roller should be used to remove air bubbles while creating a flawless finish.
The mixture needs to cure for about 10 hours before completion.

Ideal Environments

The pharmaceutical and cleanroom sectors require sterile surfaces with chemical resistance and smooth finishes.
The food and beverage sector requires hygienic surfaces with seamless finishes that fulfill all necessary safety requirements.
The chemical industry requires this material because it withstands strong solvents and reactive chemicals.
The production and logistics areas need a flat and strong surface which can handle wheeled traffic and heavy loads.
