Why Professional Substrate Preparation is the Key to a Durable Resin Floor

An industrial resin floor is one of the most durable finishes available, but its longevity is not determined by the resin itself. A premium epoxy or polyurethane system will fail prematurely if the concrete underneath is not correctly prepared. In fact, most resin floor failures—cracking, bubbling, or delamination—are directly attributable to poor preparation.

At GSS Flooring, we understand that our reputation rests on the floor’s performance decades down the line. That’s why we treat Substrate Preparation as the single most critical phase of any installation. We pair our resin expertise with the latest high-tech surface preparation equipment to guarantee an optimal bond every time.

The Three Pillars of Perfect Prep by GSS

Our comprehensive preparation service is non-negotiable and follows a strict protocol to ensure the concrete is sound, clean, and porous enough for the resin to penetrate and bond effectively.

1. Mechanical Preparation

We use powerful, specialized equipment, including shot blasters and diamond grinders, to aggressively remove weak concrete, contaminants, and previous coatings. This process creates a clean, ‘open’ surface profile (a suitable Concrete Surface Profile or CSP), which is essential for achieving the chemical and mechanical bond necessary for high-performance Epoxy or Polyurethane Screeds.

2. Contaminant and Moisture Mitigation

Industrial floors are often saturated with oil, grease, or chemicals. We use specific cleaning and degreasing protocols. Furthermore, excess moisture in the concrete can cause the resin to blister. We use sophisticated moisture testing, and if required, apply specialist Damp Proof Membranes (DPMs) before any system is applied, preventing failure from rising moisture.

3. Addressing Damage: Substrate Repairs Before Application

It is impossible to achieve a seamless finish over cracked or spalled concrete. Our service includes full Substrate Repairs before the final application. This involves:

• Crack Repair: Injecting stable resins into structural cracks.
• Levelling: Using Pump Applied Cement-Based Screeds to smooth severely uneven or damaged floors, creating the high-tolerance base required for systems like Self-Smoothing Epoxy Resins.

The Cost of Cutting Corners

Clients sometimes view preparation as an area to reduce costs, but this is a false economy. A floor installed on poor substrate may fail within months, requiring expensive, full-scale demolition and re-installation.

By investing in the proven, comprehensive preparation methods of GSS Flooring—utilising our decades of expertise and the latest technology—you ensure that your new floor achieves its maximum lifespan, often exceeding 30 years, protecting your investment and minimizing future operational disruption.
