Polymer Screed Flooring Materials

What is Polymer Modified Screed?

A polymer-modified screed is a screed formulation enhanced through the addition of polymers. These additives alter certain properties of the material, helping to improve its performance when compared with a conventional cementitious screed.

Depending on the particular formulation and flooring system selected, polymer modification can provide benefits such as:

• Improved adhesion, helping the screed bond effectively with a properly prepared substrate.
• Greater strength and durability, making it suitable for demanding environments.
• Improved resistance to water and wear, depending on the material specified.
• Reduced permeability, which can be beneficial in environments regularly exposed to moisture.
• Faster curing options, helping to reduce the amount of time an area remains unavailable.
• Thinner application depths with certain systems, where project requirements allow.
• Smooth and level finishes, including self-smoothing systems where required.
• Compatibility with resin flooring systems, allowing the screed to form part of a wider flooring specification.

However, polymer-modified screeds are not all the same. Different formulations and resin technologies provide different characteristics, which is why the operating conditions and the floor’s intended use should always influence the material selected.

Types of Polymer Screed Flooring Materials

Chemical exposure, temperature changes, traffic levels, cleaning requirements, and the amount of downtime available can all affect which flooring system will be the most appropriate for your project.

We work with several flooring technologies that can be used to meet different commercial and industrial requirements.

Epoxy-Based Flooring Systems

Epoxy resin is widely used for industrial and commercial floors due to its durability, strong adhesion, and resistance to a range of chemicals and mechanical stresses. 

When properly specified and installed, epoxy flooring can bond effectively to concrete substrates and provide a hard-wearing surface capable of coping with frequent footfall, equipment, and operational activity. Its seamless finish can also make cleaning and ongoing maintenance more manageable.

However, epoxy will not necessarily be the right choice for every project. Environments involving substantial temperature fluctuations, particular chemicals, or greater substrate movement may be better suited to another resin technology. Cure time must also be considered where an operational facility needs to return to service quickly.

Polyurethane-Based Flooring Systems

Polyurethane flooring provides another durable option for demanding commercial and industrial environments. Compared with many epoxy systems, polyurethane can offer increased flexibility alongside strong resistance to abrasion, chemicals, and changing temperatures. These properties can make polyurethane particularly useful in environments where floors are exposed to regular cleaning, mechanical stresses, or temperature variation. 

Polyurethane systems can also be modified to meet particular requirements, including slip resistance and different surface finishes. As with epoxy, the precise formulation matters. The expected traffic, chemical exposure, temperature, and cleaning regime should all be considered before specifying a polyurethane system.

Methyl Methacrylate (MMA) Flooring Systems

Where minimising downtime is a priority, Methyl Methacrylate (MMA) flooring can provide an effective solution, as it’s particularly notable for its rapid curing characteristics. This can allow floors to return to service considerably faster than systems requiring longer curing periods, making it useful for busy commercial and industrial premises where closing an area for several days may be impractical.

This makes MMA particularly valuable for refurbishment projects, maintenance programmes, and other installations operating within tight timeframes.

Rapid curing does not, however, automatically make MMA the best material for every floor. Chemical exposure, expected wear, substrate condition, and the required finish still need to be considered alongside installation speed.

Are There Any Drawbacks to Polymer Screeds?

Correct specification and installation are essential. The existing substrate must normally be carefully assessed and prepared to help achieve a reliable bond. Cracks, contamination, moisture, or an uneven substrate may require additional preparation before installation can begin.

Different materials also have their own limitations. A system with excellent chemical resistance may not offer the fastest cure time, while a rapidly curing material may not be necessary for a project where downtime is less important. Temperature, moisture, and other environmental conditions during installation may also need to be controlled.

Polymer-modified systems can additionally represent a greater initial investment than basic flooring options. However, durability, reduced maintenance requirements, and longer service life can make the overall value of a correctly specified floor more important than its upfront cost alone.

How Is a Polymer Screed Floor Installed?

Installation varies according to the chosen material, existing substrate, and required finish, but preparation is one of the most important parts of achieving a successful floor.

The process will typically begin with an assessment of the existing substrate and the requirements of the finished surface. The floor can then be prepared, with repairs and priming completed where necessary. The selected material is mixed according to its specification before being applied at the required depth. Depending on the system, it may be poured, spread, trowelled, or self-smoothed to create the required surface.

The floor is then allowed to cure. Cure times vary considerably between materials, which is why the operational requirements of the premises should be considered during specification. Additional finishes, protective systems, or markings can then be applied where required before the completed floor is inspected.

Industries That Use Polymer Screed Flooring Materials

Polymer-modified and resin flooring systems are incredibly versatile, which makes them suitable for a wide variety of commercial and industrial environments, including:

• Warehousing and distribution: Durable surfaces can withstand regular footfall, storage operations, and movement of equipment.

• Manufacturing and engineering: Hard-wearing systems can be selected to cope with mechanical stresses, oils, chemicals, and intensive use.

• Food and beverage production: Seamless, easy-to-clean flooring can support environments with demanding hygiene and cleaning requirements.

• Healthcare and laboratories: Smooth, practical surfaces can provide straightforward cleaning and maintenance.

• Education: Schools, colleges, and universities can all benefit from durable flooring designed for busy areas.

• Retail and commercial premises: Hard-wearing materials can combine practical performance with a clean, professional appearance.

• Automotive and transportation: Flooring can be specified to cope with vehicles, equipment, and operational wear.

• Sports and leisure facilities: Durability, cleanability, and slip resistance can all be considered when specifying flooring for heavily used facilities.

We also work across other sectors where a specialist floor is required, allowing the material and finish to be adapted to the particular demands of the premises.

How Much Does Polymer Screed Cost?

Costs can vary significantly from one project to another because the final price is determined by both the material selected and the conditions in which it needs to be installed.

Factors influencing the cost can include:

• The type of polymer or resin system specified
• The total floor area
• The required application thickness
• The condition of the existing substrate
• Preparation and repair work
• Required chemical, mechanical, or temperature resistance
• Slip-resistant or decorative finishes
• Site access
• Required curing and turnaround times

For this reason, assessing the project before providing a quotation offers a much more accurate indication of cost than relying on a standard price per square metre.
