| 1 | Sports suitability | Confirm that the flooring system is designed for the intended sport, movement pattern, footwear, and playing level. | Use a sports-flooring standard appropriate to the project, such as EN 14904 for indoor multi-sports surfaces. | Independent laboratory test report, product construction drawing, and intended-use statement. | A basketball court, fitness studio, indoor court, and multipurpose hall place different demands on traction, ball response, impact protection, and wear resistance. |
| 2 | Impact protection | Check area-elastic or point-elastic shock absorption, vertical deformation, and surface stability. | For indoor sports, compare results against the applicable performance class in EN 14904 or the project specification; do not rely only on foam thickness. | Test results showing shock absorption, vertical deformation, and force reduction for the complete installed system. | Correct impact performance can reduce stress on athletes while avoiding an unstable or excessively soft playing surface. |
| 3 | Slip resistance and traction | Evaluate wet and dry slip behavior, footwear compatibility, surface texture, and consistency across seams. | Require testing under the relevant sports-flooring standard and local regulations; avoid selecting solely by a generic coefficient of friction. | Laboratory slip-resistance report, maintenance instructions, and a representative installed sample. | Too little traction may increase sliding risk, while excessive or uneven traction may hinder turning and increase joint loading. |
| 4 | Ball rebound and surface response | For ball sports, check vertical ball rebound, area uniformity, rolling behavior, and levelness. | EN 14904 commonly evaluates vertical ball behavior for indoor multi-sports floors; compare the complete floor assembly, not just the top layer. | Ball-rebound test report, floor-flatness tolerance, subfloor requirements, and site acceptance procedure. | Consistent rebound and levelness improve play quality and help prevent unpredictable ball movement. |
| 5 | Wear and service life | Assess abrasion resistance, indentation recovery, resistance to rolling loads, seam durability, and expected traffic intensity. | Ask for test conditions and results rather than accepting an unsupported service-life claim; high-use facilities need more robust wear-layer construction. | Accelerated wear data, indentation test results, warranty terms, and references for comparable usage conditions. | Durability depends on the complete system, cleaning regime, footwear, equipment loads, UV exposure, and installation quality. |
| 6 | Fire and smoke performance | Check reaction to fire for the floor surface, adhesive, underlay, coating, and any backing layer as a combined system. | Request classification under the destination-market system, such as EN 13501-1 in Europe, or the applicable local building code. | Current fire-classification report covering the exact product build-up and installation method. | Fire performance can affect occupant safety, permitting, insurance, and approval for public buildings. |
| 7 | Moisture and dimensional stability | Review subfloor moisture limits, vapor control, expansion gaps, temperature range, humidity range, and resistance to curling or shrinkage. | Follow the flooring manufacturer’s measured moisture limits and the adhesive supplier’s installation requirements; never install over an unverified damp slab. | Moisture-test method, installation manual, acclimatization requirements, and compatibility statement for the subfloor. | Moisture-related failures can cause blistering, loose tiles, open joints, odors, mold growth, and premature replacement. |
| 8 | Cleaning and maintenance | Check daily cleaning, periodic deep cleaning, stain removal, recoating, disinfectant compatibility, and required equipment. | Prefer a documented maintenance schedule with recommended pH range and dilution ratios; avoid harsh chemicals unless specifically approved. | Cleaning manual, chemical compatibility list, maintenance cost estimate, and training requirements. | Correct maintenance preserves traction, appearance, hygiene, and performance while reducing lifecycle cost. |
| 9 | Environmental and indoor-air performance | Evaluate recycled content, recyclability, product transparency, volatile organic compound emissions, and responsible sourcing. | Request a product-specific EPD under ISO 14025 and EN 15804 where available, plus VOC-emission evidence under the destination-market method. | EPD, third-party VOC test, ingredient or chemical disclosure, recycled-content statement, and end-of-life guidance. | Product-specific documentation supports credible environmental comparisons and helps protect indoor air quality. |
| 10 | Installation, repair, and total cost | Compare subfloor preparation, installation time, spare-material requirements, repairability, replacement method, and disposal cost. | Calculate total cost of ownership over the planned service period, including installation, cleaning, repairs, recoating, energy use, and end-of-life handling. | Itemized quotation, installation method statement, project schedule, spare-parts policy, warranty exclusions, and lifecycle-cost model. | The lowest purchase price may not be the lowest-cost option if installation disruption, maintenance, or replacement costs are high. |
