53. Application Key Resin flooring systems protect and beautify concrete surfaces, covering all the primary market segments from decorative to industrial, institutional to commercial. 4. Properties of Declared Product as Delivered In general, the product systems are built layer by layer by mixing components within pre-measured kits. The components typically include a resin, a hardener, and an aggregate. The layers include: • Primer and/or optional moisture mitigation primer layer • One or more body layers with or without fillers and aggregates • Sealer (optional) Products produced at Key Resin facilities are in liquid form and are packaged on-site in either plastic or metal containers in different sizes of metal cans and plastic pails. 5. Declaration of Methodological Framework This EPD is considered a Cradle-to-Grave study. A summary of the life cycle stages included in this EPD is presented in System Boundary. The reference service life is outlined in Table 7 and is only applicable if all manufacturing guidelines are followed regarding site-selection and installation, found online. No known flows are deliberately excluded from this EPD. 6. Flow Diagram Figure 5: Flow Diagram

67. Manufacturing The Key Epoxy Terrazzo flooring system resin component products are manufactured in liquid form at Key Resin’s two facilities located in Batavia, OH and Phoenix, AZ and are packaged on-site in various sizes of either plastic or metal containers. The fillers and aggregates used in the Key Epoxy Terrazzo flooring system are procured by the customer (installation contractor) themselves and hence are accounted for in the installation (A5) module as an ancillary material rather than the product (A1-A3) life cycle module. Transport of manufacturing waste to disposal is included in the study. The distance was assumed to be 20 miles per PCR requirements. 8. Material Composition Table 2: Material Composition Component (Mass %) Calcium Carbonate 75 – 85 % Epoxy Resin 9 – 14 % Amine 3 – 5 % Glycidyl Ether 2-4 % Dry pigment 1 – 3 % Plasticizer 2 – 5 % Silica, amorphous treated 0.3 – 1.1% All other additives 0 – 1% 9. Packaging Table 3: Packaging Details per Reference flow Input per sq. m Value Unit HDPE Pail 0.73 kg Steel tin 0.22 kg 10. Transportation It is assumed that all raw materials are distributed by truck. The distances were modeled by material and were calculated using the supplier location and the location of manufacturing. The product is delivered to the customer via truck. Transportation distances used are based on PCR defaults. 11. Product Installation The detailed installation instructions are provided by the Key Resin Technical Service department. Installation equipment is required though not included in the study as these are multi-use tools and the impacts per functional unit is considered negligible. Apart from tools, the electricity used to power the

7tools to grind and polish the cured terrazzo surface is taken into account. It is assumed that a floor grinder with a power of 15 kW is used, and it takes 1 minute on average to grind and polish 1 m2 of terrazzo surface. None of the products in the system requires a sprayer for application. Therefore, no spraying application efficiency is taken into consideration. The only product loss accounted for is that 2% of wet mass of the coating remains unused and is disposed as solid waste in the C1-C4 module, as required by the reference PCR. For the Key Epoxy Terrazzo product, the fillers and aggregates used are procured by the customer themselves and hence are accounted for in the installation (A5) module as an ancillary material rather than the product (A1-A3) life cycle module. Packaging waste is generated and disposed of in this stage. Emissions released from the drying of the coating are modeled as individual releases. These emissions were taken from VOC testing reports. 12. Use In this study, the product system does not require repairing or refurbishment under normal use circumstances. However, regular cleaning is needed and recoating over the whole service life of a building (60 years) is required. The maintenance scenario is per PCR guidelines. The cleaner selected for the study is a pH neutral cleaner with an active ingredient modeled as ethoxylated alcohol. Additionally, the product is reapplied at the end of its reference service life, and these impacts are found within stage B4. The VOC emissions during the use phase are negligible and pass the requirements of the California Department of Public Health v1.2 (CDPH – CA 01350) indoor emissions testing standard. 13. Reference Service Life Since resinous flooring products may be replaced before they technically fail, the reference service life of the products, as dictated by the PCR, is reported with both an estimated market service life (MSL) and an estimated technical service life (TSL). According to the PCR, the reference service life (RSL) details vary by coating type and installation type. Since Key Resin’s products can be used in both commercial and industrial applications, results for both applications are provided within this report. Details on specific scenarios is given in the Life Cycle Assessment Scenarios section. 14. Disposal As per the PCR Section 4.4, any coating including the initial applied coating and those recoated-on top of the initial one is treated as incremental mass at end-of-life. Due to the lack of primary data, it is assumed all the coating is sent to landfill. In accordance with the PCR, it is assumed the unused coating travels 32 km to the point of disposal and is landfilled.

917. Estimates and Assumptions All estimates and assumptions are within the requirements of ISO 14040/44. The majority of the estimations are within the primary data. The primary data was collected as annual totals including all utility usage and production information. For the LCA, the usage information was divided by the production to create an energy and water use per unit weight. As there are different products produced at this facility, it is assumed all products are using the same amount of energy. Another assumption is that the installation tools are used enough times that the per square meter impacts are negligible. 18. Cut-Off Rules Material inputs greater than 1% (based on total mass of the final product) were included within the scope of analysis. Material inputs less than 1% were included if sufficient data was available to warrant inclusion and/or the material input was thought to have significant environmental impact. Cumulative excluded material inputs and environmental impacts are less than 5% based on total weight of the functional unit. In addition, as per PCR, substances that are characterized as hazardous according to Globally Harmonized System are not cut off. 19. Data Sources Primary data was collected by KRC associates for onsite energy, water and waste during the course of manufacturing. When primary data did not exist, secondary data for raw material production was used from Sphera LCA for Experts (fka GaBi) 10.7.1.28. All calculation procedures adhere to ISO14044. 20. Data Quality Geographical Coverage The geographical scope of the manufacturing portion of the life cycle are Batavia, OH and Phoenix, AZ. This EPD uses country specific energy datasets that take into account US eGrid specific energy and transportation mixes. Overall geographic data quality is considered good. Time Coverage Primary data was provided by KRC associates and represent June 2022 to June 2023. Using 2022/2023 data meets the PCR requirement that manufacturer specific data be within the last 5 years. Time coverage of this data is considered very good. Data necessary to model cradle-to-gate unit processes was sourced from Sphera LCI datasets. Time coverage of the MLC datasets varies from approximately 2006 to present. All datasets rely on at least one 1-year average data. While there were a couple of datasets used that are outside of the requirement of the PCR that all data be updated within a 10-year period, these were deemed appropriate as they represent the best technological and geographical coverage available. The specific time coverage of secondary datasets can be referenced in the dataset references table in the background LCA report.

10 Technological Coverage Primary data provided by KRC are specific to the technology that the company uses in manufacturing their product. It is site specific and considered of good quality. It is worth noting that the energy and water used in manufacturing the product includes overhead energy such as lighting, heating and sanitary use of water. Sub-metering was not available to extract process only energy and water use from the total energy use. Sub-metering would improve the technological coverage of data quality. Data necessary to model cradle-to-grave unit processes was sourced from Sphera LCI datasets (GaBi). Technological coverage of the datasets is considered good relative to the actual supply chain of KRC. While improved life cycle data from suppliers would improve technological coverage, the use of lower quality generic datasets does meet the goal of this EPD. Completeness The data included is considered complete. The LCA model included all known material and energy flows, with the exception of what is listed in Section 18. As pointed out in that section, no known flows above 1% were excluded and the sum of all excluded flows totals less than 5%. 21. Period under Review The period under review is June 2022 to June 2023. 22. Allocation General principles of allocation were based on ISO 14040/44. To derive a per-unit value for manufacturing inputs such as electricity, thermal energy and water, allocation based on total production by mass was adopted. As a default, secondary MLC datasets use a physical basis for allocation. 23. Comparability and Benchmarking The user of the EPD should take care when comparing EPDs from different companies. Assumptions, data sources, and assessment tools may all impact the uncertainty of the final results and make comparisons misleading. Without understanding the specific variability, the user is therefore, not encouraged to compare EPDs. Even for similar products, differences in use and end-of-life stage assumptions, and data quality may produce incomparable results. Comparison of the environmental performance of flooring products using EPD 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 when not considering the building energy use phase as instructed under this PCR.

11 Full conformance with the PCR for Products allows EPD comparability only when all stages of a life cycle have been considered. However, variations and deviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream or downstream of the life cycle stages declared.

14 Life Cycle Assessment Results All results are given per functional unit, which is one square meter of covered and protected flooring surface for 60 years. Impact results have been calculated using both TRACI 2.1 and IPCC AR5 characterization factors. LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. These six impact categories are globally deemed mature enough to be included in Type III environmental declarations. Other categories are being developed and defined and LCA should continue making advances in their development, however the EPD users shall not use additional measures for comparative purposes. See Impact Category Key below for definition of acronyms.

Significant data limitations currently exist within the LCI data used to generate waste metrics for Life Cycle Assessments and Environmental Product Declarations.

Significant data limitations currently exist within the LCI data used to generate waste metrics for Life Cycle Assessments and Environmental Product Declarations.

Significant data limitations currently exist within the LCI data used to generate waste metrics for Life Cycle Assessments and Environmental Product Declarations.

Significant data limitations currently exist within the LCI data used to generate waste metrics for Life Cycle Assessments and Environmental Product Declarations.

Significant data limitations currently exist within the LCI data used to generate waste metrics for Life Cycle Assessments and Environmental Product Declarations. The waste metrics were calculated in a way conformant with the requirements of ISO 21930:2017, but these values represent rough estimates and are for informational purposes only. As such, no decisions regarding actual cradle-grave waste performance between products should be derived from these reported values.

24 Life Cycle Assessment Interpertation For all impact categories the vast majority of impacts are aggregated in the B4 Replacement phase of the life cycle of the product. The second largest life cycle stage is A1-A3, which is raw material sourcing, transportation and manufacturing. For Key Epoxy Terrazzo, in the sourcing and extraction stage, the largest contributors to the impacts in terms of raw materials are terrazzo matrix resin (41%) and terrazzo matrix hardener (25%). Within manufacturing, plastic packaging contributes to 8% of overall GWP impacts while steel packaging contributes to 3%. Shipping to customer contributes around 1-3% of total GWP impacts, while installation contributes around 1-2% of GWP impacts, depending on the RSL scenario. Finally, disposal of the product to landfill contributes 1-3% to total GWP impacts. 28.
