Comparison of the environmental performance of products usingEPD information shall be based on the product’s use and impacts at the building level, and therefore EPDs may not be used for comparability purposes whennot considering the whole building life cycle. EPD comparability is only possible when all stages of a life cycle have been considered. However, variations anddeviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream ordownstream of the life cycle stages declared.

A background LCI database is the databaseused to model generic or non-specific data.Data QualityThe quality of inventory data is evaluated based on several criteria, including precision, completeness, consistency, and representativeness.Stonshield AggregateStonhardPage 6 / 12

Precision and completeness:Precision: The inventory data used in this study were either directly measured, calculated, or estimated based on primary data sources, ensuring highprecision. Background data from ecoinvent v3 database also has documented precision to the extent available.Completeness: The product system's mass balance and inventory completeness were thoroughly checked. Some exclusions were made in line with thePCR requirements, such as personnel impacts, R&D activities, business travel, secondary packaging, point of sale infrastructure, and the coatingapplicator. However, no data was intentionally omitted.Consistency and reproducibility:Consistency: Primary data were collected with a similar level of detail, while background data primarily came from the ecoinvent database, with otherdatabases used only if necessary or more representative. The modeling approach and other methodological choices were applied consistentlythroughout the model.Reproducibility: This study ensures reproducibility by providing comprehensive disclosure of input-output data, dataset choices, and modelingapproaches. A knowledgeable third party should be able to approximate the results using the same data and modeling methods.Representativeness:Temporal: Primary data were collected for a 12 month period starting on June 2023 and ending on May 2024 to ensure the representativeness of post-consumer content. Secondary data from the ecoinvent v3 database is typically representative of recent years.Geographical: Primary data represent Stonhard's production facilities in Mapple Shade, NJ, US. Where applicable, differences in electric grid mix wereconsidered using appropriate secondary data. The use of country-specific data ensures high geographical representativeness, and proxy data wereonly used when country-specific data were unavailable..Technological: Both primary and secondary data were tailored to the specific technologies studied, ensuring high technological representativeness.Life Cycle Module DescriptionPrimary data were collected for a 12-month period from June 2023 and ending on May 2024 to ensure technical, geographical, and temporalrepresentativeness. The manufacturing process starts with the reception of raw materials, typically in the form of chemical packages (cans, supersacks,bags, pails, among others). Next, the raw materials are mixed to forms resins and additives. After this step, the products are packaged and distributed tovarious distribution centers. Non-hazardous waste, consisting mainly of packaging waste materialas, is sent for disposal, incineration, and/or recycling.Hazardous waste consist on manufacturing, product losses and its disposal is model according to PCR descriptions (solvent-based coatings are incineratedfor energy recovery and water-based coatings are sent to landfill).LCA DiscussionAllocation ProcedureAllocation of co-products was avoided, to the extent it was possible, based on the guidance given in ISO 14044:2006, 4.3., in ISO 21930:2017. Energy useand VOC emissions at the Maple Shade, NJ factory were allocated by mass. Overhead burdens (building heating and corporate use consumption) wereexcluded using a square footage factor, that benchmarked and validated with process engineering models of resinous floor coatings production. The processdo not consume process water or generate wastewater . Solid waste was estimated using packaging masses and material losses and allocated followingthe polluter pays principle.Cut-off ProcedureThe system boundary was defined based on relevance to the goal of the study. For the raw material (A1) and process related inputs (A3), all availableenergy and material flow data have been included in the model. Exclusions allowed by the PCR such as secondary and tertiary packaging, wereStonshield AggregateStonhardPage 7 / 12

The product stage (A1-A3) has thehighest environmental impact, especially due to raw material production and energy use, impact amplified in the use phase (B4) from recoatings. The Marketscenario shows higher use-phase impacts due to a shorter estimated service life (ESL).End-of-life impacts are relatively low, as products are assumed to belandfilled with building demolition waste. Switching to renewable energy is advised for products with high manufacturing energy demands. Themanufacturer should explore lower-impact raw materials and work with suppliers using sustainable methods or renewable energy to enhance productsustainability.The environmental impact results of products in this document are based on a declared unit and therefore do not provide sufficient information to establishcomparisons. The results shall not be used for comparisons without knowledge of how the physical properties of the product impact the precise function atthe construction level. The environmental impact results shall be converted to a functional unit basis before any comparison is attempted.A manufacturer shall not make claims based on an industry-average EPD which leads the market to believe the industry-average is representative ofmanufacturer-specific or product-specific results.Stonshield AggregateStonhardPage 11 / 12
