Types of Accessories Used in the Installation of Industrial, Commercial, and Decorative Floors

1. Types of Accessories for Concrete Floors and Screeds

The installation of industrial concrete floors and cement-based screeds requires precision and structural stability.

To achieve high-quality results, several essential accessories are employed during the installation process.

These components ensure reinforcement, prevent structural failures, and aid in proper alignment.

1.1 Reinforcement Spacers (Rebar Chairs and Mesh Spacers)

Reinforcement spacers, such as plastic or metal rebar chairs, are crucial for maintaining the correct positioning of steel reinforcement bars and mesh within the concrete structure.

By ensuring consistent concrete cover, spacers contribute to improved load distribution and durability.

Key Functions:

• Guarantee the specified concrete cover

• Prevent displacement of reinforcement during pouring

• Improve structural performance and corrosion resistance

1.2 Expansion Joint and Edge Isolation Materials (e.g., Edge Insulation/Expansion Tape)

Edge insulation tape, commonly referred to as expansion joint tape or damper tape, is used along perimeter walls and columns to allow controlled expansion and contraction of the slab.

This tape absorbs structural movements, reduces cracking risks, and contributes to the longevity of the flooring system.

Applications:

• Around walls, columns, and embedded objects

• Between adjacent slabs

• In floor screeds to isolate load-bearing elements

1.3 Screed Guides and Leveling Beacons (Screed Rails/Markers)

Screed guides, or screed markers, help in achieving a uniform thickness and flatness in concrete and screed applications.

These metal or plastic rails are temporarily fixed to the substrate to guide leveling tools or screed bars.

Advantages:

• Enhance accuracy of the screed height

• Allow rapid leveling

• Reduce material waste and rework

2. Types of Accessories for Polymer Floor Systems

Polymer flooring systems, including epoxy, polyurethane, and MMA-based coatings, require specific accessories to ensure adhesion, uniform coverage, and edge finishing.

These systems are prevalent in industrial and commercial facilities due to their resistance to chemicals, mechanical wear, and impact.

2.1 Primer and Moisture Barrier Systems

Primers serve as adhesion promoters between the concrete substrate and the polymer layer.

Moisture barrier primers are formulated to resist residual humidity in concrete and prevent delamination or blistering of the polymer flooring.

Main Types:

• Solvent-free epoxy primers

• Polyurethane-based moisture-tolerant primers

• Penetrating primers for dust control

2.2 Floor Coving Accessories (Coving Strips and Rounding Trowels)

Coving accessories, such as prefabricated coving strips and specialized trowels, are used to create seamless transitions between floor and wall junctions.

These prevent dirt accumulation and enhance hygiene in cleanrooms, food processing, and pharmaceutical environments.

Benefits:

• Create watertight floor-to-wall transitions

• Facilitate easy cleaning and maintenance

• Improve overall floor system durability

2.3 Crack Bridging and Joint Tapes

Flexible crack-bridging tapes and reinforcement fabrics are embedded within the polymer layers to span existing or anticipated substrate cracks and movement joints.

This prevents visible cracking on the surface finish.

Functions:

• Absorb movement and prevent reflective cracking

• Enhance the structural integrity of the polymer layer

• Support long-term performance in dynamic environments

2.4 Application Tools and Edge Trims

High-quality application tools such as spike rollers (for deaeration), notched trowels (for adhesive spreading), and edge trims (for transition areas) are essential for professional-grade polymer floor installations.

3. Types of Accessories for Decorative Floor Coverings

When installing residential and commercial decorative flooring systems, such as parquet, laminate, linoleum, vinyl tile (PVC), and ceramic tiles, appropriate accessories are required to ensure aesthetic quality, stability, and durability.

3.1 Underlayment Materials

Underlayment is critical for cushioning, sound insulation, and moisture protection beneath decorative floor coverings. Depending on the floor type, the underlay material may differ in density, thickness, and composition.

Examples:

• Polyethylene foam underlays (for laminate and parquet)

• Cork sheets (for wood flooring)

• Rubber or felt underlays (for sound absorption)

3.2 Adhesives and Fixing Materials

Adhesive systems play a central role in the proper bonding of floor coverings to the substrate. Depending on the material, dispersion adhesives, reactive (2K PU or epoxy) adhesives, or pressure-sensitive adhesives may be used.

Common Uses:

• Dispersion adhesives for PVC and linoleum

• Polymer adhesives for parquet

• Cement-based tile adhesives for ceramic floors

3.3 Expansion Joints and Profiles

Profiles for floor transitions and expansion joints accommodate dimensional changes and movement while maintaining visual continuity and safety. They are made of aluminum, stainless steel, or PVC.

Types:

• Transition profiles

• Stair nosing profiles

• Edge and corner profiles

3.4 Grouts and Sealants

Joint grouts (cement-based, epoxy, or silicate) and perimeter sealants help prevent water ingress, improve aesthetics, and reduce dirt accumulation in decorative tiled floors.

Selection Factors:

• Tile type (porous vs. non-porous)

• Environmental exposure (e.g., kitchens, bathrooms)

• Chemical or mechanical resistance requirements

Conclusion: Optimizing Floor System Performance through Accessory Selection

Each flooring system type—be it industrial concrete, polymer coating, or decorative floor covering—relies on a specific set of accessories to achieve technical performance and long-term reliability.

The selection and correct application of these accessories directly influence load resistance, moisture protection, dimensional stability, and aesthetic quality.

In industrial and commercial environments, where floors are subjected to dynamic loads, chemical exposure, and temperature fluctuations, the use of appropriate joint tapes, edge reinforcements, and moisture barriers is critical.

In decorative flooring, underlayments, adhesives, and profiles ensure dimensional stability and user comfort.

For architects, engineers, and installers, understanding the function of each accessory is essential for the correct specification and installation of flooring systems that meet technical, operational, and aesthetic requirements.
