Start with the complete system schedule
Ask the estimator to list each proposed material in installation order: repair products, primers, membranes, mortars, build coats, broadcasts, topcoats, line markings and joint materials. Record the exact product, manufacturer, intended role and location rather than accepting one family name for the entire build-up. Epoxy may be proposed in one layer while another chemistry performs a different role. The comparison should explain how the components work together and which document establishes compatibility, recoat windows and installation conditions.
Tie every layer to a confirmed exposure
Use the floor-zone map to connect the system to vehicle traffic, rolling loads, impacts, water, cleaners, chemicals, temperature, daylight, pedestrian movement and maintenance. Ask which exposure each layer is intended to address and which remains outside the claim. Avoid generic statements such as chemical resistant without the substance, concentration, contact time, temperature and current product data. If the real exposure is not yet known, keep the system decision conditional rather than turning a marketing description into a property-specific guarantee.
Compare the substrate requirements
For each option, request the required concrete condition, age where relevant, cleanliness, surface profile, moisture limits, repair compatibility and environmental range. Ask what happens when the existing floor does not meet those conditions. A system that looks attractive on a data sheet may require preparation or moisture conditions that are not yet established at the property. Keep the proposed test methods and acceptance source beside the system schedule so a price cannot be compared independently of the surface on which it depends.
Separate cure stages from calendar promises
Ask for the written distinction between recoat, tack-free, light foot traffic, equipment traffic, full service and chemical exposure where those stages apply. Record the temperature, humidity, ventilation and thickness assumptions behind each interval. The property's available shutdown should be compared with the complete sequence, including preparation, repairs, intermediate layers, markings and inspection—not only the final coat's advertised time. Reopening criteria must come from the current product documentation and responsible project decision-makers after actual conditions are known.
Review finish, texture and cleaning together
Colour and gloss are only part of the finish decision. Discuss texture by zone, expected contaminants, footwear, wheels, cleaning equipment, cleaning products and the need to remove soil from a textured surface. WorkSafeBC identifies water, oil, grease, dust, uneven flooring and obstructed routes among slip or trip concerns, but it does not prescribe one coating texture for every workplace. The responsible employer and qualified project team must assess the actual walking surfaces and work activities rather than relying on an unsupported universal slip claim.
Check UV and appearance expectations
Identify daylight at entrances, open parkade edges, loading doors or exterior transitions. Ask what change in colour, gloss or appearance is addressed by the proposed layers and what is excluded. Request a representative sample or mock-up when appearance matters, then record the substrate, texture and lighting limitations of that comparison. A small sample does not prove performance across a worn or repaired slab, and a broad statement about UV stability should be tied to the exact exposed product and current technical document.
Read product and safety documents as a set
Request current product data sheets, installation instructions and safety data sheets for every material expected on site. WorkSafeBC's WHMIS guidance explains the workplace role of labels and safety data sheets for hazardous products. The responsible employer must use that information for training, handling, storage, ventilation and emergency planning. Technical data and safety information answer different questions; neither should be replaced by a sales brochure. Confirm revision dates and note any conflict that needs clarification before the material is approved.
Use a comparison matrix, not a winner label
Place proposals side by side using the same rows: floor zones, preparation, repairs, tests, each system layer, thickness or coverage evidence, texture, colours, cure assumptions, quality checks, phasing, exclusions, maintenance and warranty conditions. Highlight blank cells and qualifications instead of awarding points to the shortest cure or lowest total without context. The purpose is to expose different assumptions and request clarification. Final selection still requires the actual property evidence, current manufacturer documents and accountable technical review.
