Premium Indoor Polyurethane Coating
(EC1PLUS Certified & Ultra-Low VOC Specification)
Product Overview
The definitive concealed waterproofing solution for highly sensitive and occupied indoor environments. This single-component, solvent-free polyurethane membrane is engineered to deliver impenetrable moisture defense while maintaining the industry’s most rigorous Indoor Air Quality (IAQ) standards. Awarded the prestigious GEV-EMICODE® EC1PLUS certification, it cures into a highly elastomeric, monolithic barrier with virtually zero emissions, making it the mandatory specification for unventilated, non-exposed applications.
Core Advantages
▪ EC1PLUS & Green Building Certified (Zero-TDI): Formulated completely solvent-free with zero free TDI, exceeding strict global VOC regulations. This “Very Low Emission” profile directly contributes to LEED®, BREEAM, and WELL™ building certifications, making it the ultimate choice for environmentally conscious developers.
▪ Occupied-Space Application (Zero-Downtime): The odorless, cold-applied curing process eliminates toxic
off-gassing. This allows contractors to execute structural waterproofing in fully operational facilities—such as hospitals, schools, and luxury hospitality—without requiring costly evacuations, forced ventilation, or operational downtime.
▪ Extreme Elastomeric Memory: Maintains profound flexibility even in extreme cold-climate sub-flooring.
It effortlessly bridges structural micro-cracks and accommodates the dynamic movement of concrete substrates beneath ceramic tile, stone, and architectural wearing courses.
▪ Primer-less Universal Adhesion: Delivers aggressive, permanent bonding to diverse interior substrates
(concrete, masonry, gypsum board) without the need for complex mixing or open flames, significantly streamlining
the installation process in confined spaces.
Engineered Applications
▪ Concealed waterproofing for indoor high-humidity zones (commercial kitchens, mechanical rooms, public restrooms).
▪ Moisture defense beneath premium tile and stone in luxury hotel wet-rooms and spas.
▪ Critical installations in zero-ventilation environments and subterranean basements.
▪ Sensitized environments requiring strict IAQ compliance: healthcare facilities, cleanrooms, and educational institutions.
System Integration: The EC1PLUS Concealed Wet-Room Matrix
To guarantee absolute watertight integrity in highly sensitive, zero-ventilation environments (hospitals, luxury hotel spas, commercial kitchens), you must eliminate the structural vulnerabilities hidden beneath the final tile surface. A catastrophic leak in a continuously occupied facility results in devastating mold remediation costs and operational shutdowns. Eliminate capillary water tracking, secure plumbing penetrations, and guarantee heavy-duty tile adhesion by integrating these mandatory indoor components:
90-Degree Transition & Shower Curb Skeletal Reinforcement:
Must pair with: High-Tenacity Elastomeric Flash-Bond Matrix
Why it’s critical: Liquid membranes inherently thin out over sharp 90-degree wall-to-floor junctions, shower curbs, and built-in niches. As the building undergoes normal structural settlement, these unreinforced thin zones will micro-fracture. This cold-applied, zero-VOC non-woven tape must be centered over all angular transitions. It acts as a high-tensile structural “skeleton” that absorbs structural shifting, while its fleece surface seamlessly integrates with the PU liquid to prevent edge-tearing.
Drain Flange & Plumbing Penetration Gas-Lock:
Must pair with: Architectural High-Performance PU Sealant
Why it’s critical: Floor drains and PVC plumbing penetrations are the absolute highest-risk zones for water ingress and sewer gas migration in indoor environments. Brushing a liquid coating directly against smooth PVC piping is an engineering liability. This dynamic polyurethane sealant must be heavily extruded around all drain flanges and pipe boots to create an elastomeric, watertight, and gas-tight gasket before the main membrane is applied.
Direct-to-Tile Heavy-Duty Friction Anchoring:
Must pair with: Industrial Grip-Engineering Matrix
Why it’s critical: Once the highly elastomeric PU membrane cures, it creates a smooth, water-repellent surface. Applying heavy porcelain or natural stone tiles directly to this smooth finish with standard thin-set mortar guarantees severe tile slippage and hollow-sounding floors. Applying this suspension-quartz grip primer over the cured PU membrane creates an aggressive, high-friction mechanical key, allowing for immediate, zero-slip tile installation in commercial wet-rooms.
