Specialty coatings are system-driven. The cost is determined as much by substrate preparation and application requirements as by the coating material itself.
Identify the complete coating system
Read finish schedules and specifications for primer, intermediate coats, topcoats, aggregate, broadcast systems, sealers, and required dry-film thickness. Epoxy, urethane, elastomeric, traffic, and industrial systems should be kept separate.
Measure by substrate and condition
Quantify floors, walls, steel, concrete, or other substrates independently. New concrete, existing coated surfaces, corroded steel, and contaminated floors can require very different preparation.
Surface preparation can dominate the labor
Grinding, shot blasting, cleaning, profiling, patching, crack repair, moisture mitigation, masking, and containment should be carried when required. Do not assume the substrate arrives ready for coating.
Account for application conditions
Temperature, humidity, cure windows, ventilation, occupied spaces, shutdown periods, access, and return-to-service requirements can affect sequencing and labor.
Keep fireproofing separate
Intumescent fire-resistive coatings belong with the specified fireproofing system when they provide structural fire protection. Keeping that scope distinct avoids overlap with architectural or industrial coatings.
