Product description
Stontrace LC5 is a high-performance resin floor coating system designed to add a durable, protective layer over prepared concrete or existing resinous floors. Used as a standalone coating or in conjunction with Stonhard flooring systems, it helps enhance floor durability and appearance while improving cleanability and maintenance. Stontrace LC5 is supplied as a system with coordinated coating components (including a pigmented primer/topcoat material and a separate topcoat), enabling a robust finished surface suited for demanding industrial and commercial environments where added abrasion and chemical resistance are needed.
Interpretation
Raw materials are sourced from suppliers, transported to manufacturing facilities, and mixed to produce products.
The product stage (A1-A3) has the highest environmental impact, especially due to raw material production and energy use, impact amplified in the use phase (B4) from recoatings.
The Market scenario shows higher use-phase impacts due to a shorter estimatedservice life (ESL).
End-of-life impacts are relatively low, as products are assumed to be landfilled with building demolition waste.
Switching to renewable energy is advised for products with high manufacturing energy demands.
The manufacturer should explore lower-impact raw materials and work with suppliers using sustainable methods or renewable energy to enhance product sustainability.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
