EPOXY FLOORING SYSTEM FOR LABORATORIES WITH LIGHT CHEMICAL USE

Introduction

Laboratories with light chemical exposure require flooring systems that provide chemical resistance, hygiene, and mechanical strength while maintaining a smooth, easily cleanable finish. Although the chemical exposure is moderate, regular contact with reagents, solvents, and cleaning agents demands a protective floor with long-term reliability and resistance.

The Ressi EPO System – Chem Might from Ressichem combines reliable primers, self-levelling underlayment (if needed), and a high-performance chemically resistant epoxy topcoat. This system ensures lasting durability, cleanability, and chemical protection ideal for controlled laboratory environments.

Recommended Use Cases

• Educational and institutional laboratories
• Pharmaceutical and analytical QC labs
• Light chemical handling rooms
• Research and development areas
• Diagnostic and product testing laboratories
• Cleanrooms and sample preparation zones

Step-Wise System Description

Step 1: Surface Preparation

• A well-prepared substrate ensures strong adhesion and system longevity.
• Begin with a sound, levelled screed
• Mechanically grind or lightly shot blast the surface to remove laitance, dust, and contamination.
• Clean thoroughly to remove oil, grease, and other residues.
• Fill cracks and voids with an epoxy-based repair mortar. All damages should be repaired using suitable repairing materials. Ressichem has a wide variety of repairing materials available.
• Confirm that the substrate moisture content is below 5% before proceeding.

Step 2: Application of Ressi SLS Primer – 1 (if Required)

• Where levelling is required, apply Ressi SLS Primer – 1, a latex-based primer that enhances adhesion between the substrate and the self-levelling compound.
• Stir thoroughly before use.
• Apply uniformly by roller, brush, or spray.
• Avoid puddling and allow to dry to a tack-free finish (approximately 2–4 hours).

Step 3: Application of Ressi SLS 610 Self-Levelling Screed (if Required)

• If the substrate requires correction or levelling, apply Ressi SLS 610, a self-levelling cementitious screed.
• Mix with clean water per manufacturer’s recommendations using a low-speed mixer.
• Pour and spread evenly using a gauge rake or trowel.
• Use a spiked roller to release entrapped air and achieve a smooth finish.
• Ressi SLS 610 does not require curing, but it must be allowed 7–14 days for moisture release depending on ambient conditions.
• Proceed with epoxy application only once the moisture content is verified below 5%.

Step 4: Application of Ressi EPO Primer LV

• Once the surface is fully dry and stabilized, apply Ressi EPO Primer LV, a low-viscosity, solvent-free epoxy primer that penetrates and seals the substrate for improved adhesion.
• Mix resin and hardener thoroughly according to the specified ratio.
• Apply uniformly using a roller or brush.
• Avoid puddles and ensure complete coverage.
• Allow the primer to cure overnight before applying the epoxy topcoat.

Step 5: Application of Ressi EPO Chem Might

• The final coat consists of Ressi EPO Chem Might, a high-build, solvent-free epoxy coating designed to deliver chemical resistance and surface durability under light laboratory conditions.
• Mix both components thoroughly using a low-speed drill.
• Apply evenly using a roller or squeegee, ensuring consistent coverage.
• Apply in a single layer at a minimum total thickness of 1000 microns.
• Allow 48–72 hours before opening for mild traffic, depending on ambient temperature.
• Allow a full cure of 7 days before subjecting the floor to chemical exposure or routine use.
• This results in a seamless, dense, and chemical-resistant floor capable of withstanding mild acids, alkalis, and solvents.

System Advantages

• Chemical Resistance: Protects against mild acids, alkalis, and solvents.
• Durability: Resists abrasion and light mechanical stress.
• Hygienic & Seamless: Non-porous, easy to clean, and prevents microbial buildup.
• Single-Coat Efficiency: Achieves protection at ≥ 1000 microns.
• Controlled Cure Schedule: Ready for mild traffic in 48–72 hours; full cure in 7 days.
• Professional Finish: Smooth, semi-gloss appearance ideal for laboratories.

Maintenance Guidelines

• Clean regularly with neutral pH, non-abrasive detergents.
• Avoid strong acids or solvent cleaners.
• Promptly clean chemical spills.
• Inspect the surface periodically and recoat if required to maintain chemical protection.
