A complete Sika epoxy flooring system is made up of different products selected according to the concrete condition, moisture levels, traffic requirements and desired finish. A typical system may include a primer, epoxy coating, optional decorative flakes and a protective topcoat.

ProTrade Warehouse supplies a range of Sika flooring products including primers, moisture barriers, epoxy coatings and protective finishes for garages, workshops, warehouses, commercial spaces and industrial applications.

The correct primer depends on the condition of the concrete and the requirements of the project.

Common Sika primer options include:

• Sikafloor 158 W Fast Barrier – used where moisture protection is required and suitable for systems specified for damp or newer concrete.
• Sikafloor 161 – a versatile epoxy primer suitable for a wide range of Sika flooring systems.
• Sikafloor 94 – a low-viscosity epoxy primer suitable for various applications and repair work when mixed with suitable aggregate.

The epoxy basecoat provides the main thickness, colour and durability of the flooring system. Sikafloor 264 is a coloured, high-build epoxy coating suitable for solid-colour flooring systems and commercial, workshop and industrial applications.

A common solid-colour system includes:

• Sikafloor 161 primer
• Sikafloor 264 epoxy coating
• A suitable protective topcoat depending on the application

A decorative flake floor combines an epoxy primer, coloured epoxy basecoat, decorative flakes and a clear protective coating.

A typical Sika flake system includes:

• Sikafloor 161 – epoxy primer for improved adhesion
• Sikafloor 264 – coloured epoxy basecoat used for broadcasting flakes
• Elite Flakes – decorative flakes broadcast into the wet epoxy coating
• Sikafloor 169 – clear epoxy used to seal and protect the flake system

This creates a seamless, durable and easy-to-maintain decorative finish.

A protective topcoat can improve resistance to abrasion, chemicals, scratching and UV exposure. The best option depends on the environment and required performance.

Common options include:

• Sikafloor 359 AU – a polyurethane coating providing a durable protective finish and improved UV resistance.
• Sikafloor 550 PA – a polyaspartic coating offering high UV stability, durability and fast curing for suitable applications.
• Sikafloor 169 – a clear epoxy coating commonly used as part of decorative flake flooring systems.

Proper surface preparation is essential for the performance of any epoxy flooring system. Concrete should be mechanically prepared where required, such as by diamond grinding, to remove contaminants and create a suitable surface profile. Cracks, spalls and surface imperfections should be repaired before coating.

The prepared surface should also be assessed for moisture and other conditions that may affect adhesion or curing. Always follow the relevant Sika Technical Data Sheets for application methods, coverage rates, recoat times and curing requirements.
