FAQ: How does HRCSA single coat, single component, 3 step application process reduce costs and save time Compared to multi-component System?

HRCSA Single component, single coat system	Multi component, multi coat systems
HRCSA Penetrant/Sealer (gaps only) Self Priming Topcoat [Single Coat (Wet on Wet)  3 Step System]	Two Component Multi Coat Catalyzed Solvent Based System
Tin to spray:  No mixing     Paint lines loaded with HRCSA remain in the paint lines from beginning till end of project.	One dedicated full-time mixer: Preparation time [Added cost] Mixing time. Sweat in time.
HRCSA can be drawn straight from drums.	Must work with pails. [Added cost]
No HRCSA is wasted (other than spillage).   Even end of project coating material (including what is flushed out of the paint system at end of project) is preserved for future maintenance touch-ups.	Must flush out paint lines between shifts. [Added cost]  Flushed catalyzed material coming out of the paint lines needs to be managed like hazardous waste.   Additional material costs:   Solvents for flushing lines. [Added cost]  Additional hazardous waste management fees. [Added cost]   Solvents (flushing lines) Catalyzer Solvents Catalyzed materials Packaging Handling Cataloguing
HRCSA Penetrant Sealer only used at gaps in crevice corroded and pack rusted joints, connections and bearing faces. This does not add man-hours due to wet-on-wet characteristics.   HRCSA penetrant is not loaded into paint lines.   Single coat application.   Apply and keep production going. No Pre-Prime required on flat surfaces only apply a single coat of HRCSA Self Priming Topcoat application.   Rain starts, production stops, blow-down surface keep moving when rain is over.	Multi coat system Pre-Prime coating systems and topcoat requires two painting passes.   Apply pre-prime coat. Then wait.   DUPLICATION OF COSTS:   Reloading paint lines with different chemistry / having to return to apply 2nd coat on entire surface. Other risks:   Rain that stops production requires a complete production reset to reinitiate the process. [Added cost]
Single component, single coat self-priming topcoat. No wasted material.   HRCSA Penetrant (joints connections only) requires average 10% more material costs.	A1) Pre-prime A2) Topcoat = double the purchase volume. + double the labor + waste associated with paint line flushing (after every shift) + leftover waste (which cannot be used once mixed)   + losses caused by paint line flushing and catalyzation.    material required to fill in connections and pack rust.
Less mobilization days, less job cost, projects finish ahead of schedule. One coat makes for no weather delays and once the coating is applied you are done and are getting paid. (+ cost)	Because of two coats and possible delays in getting the second coat on within cure time limitations and weather constraints, workdays could be notably extended. What is the cost of additional mobilization days. (– cost)
Only one airless system is required. No cleaning except for at end of job.	Two chemistries require two airless systems. (Double the equipment rental.)   OR   When only one airless system available extra time, (shifting from product type to the other) extra solvent (flushing lines, cleaning equipment wasted catalyzed product between changes (flushing lines) Twice the effort (and standing by).
HRCSA less mobilization days, smaller crews to support the coating process.	Increased mobilization days [2 coat system / a fully repeated process.]   Or increased manpower (and equipment) to get same job done.
HRCSA is a wet-on-wet system with no wait time between application of HRCSA Penetrant/Sealer in gaps created in pack rusted joints, crevices, back-to-back angles, corrosion frozen bearings or tubing on steel structures such as bridges, towers, cranes, conveyor systems, cable suspension systems and vehicle frames where gaps exist. The HRCSA Self Priming Topcoat is then applied wet on wet with no cure time for Penetrant/Sealer before Topcoat application. No delay in completing an area to be coated and then getting paid. (+ cost)	CURING SCHEDULE is a limitation. (HRCSA has not curing time limitations.)
HRCSA coatings cure by oxidation so there is no pot life.   Purged paint lines (end of project) can be stored for future use.   When properly sealed, ‘no’ shelf life limitations. (+ cost)	Pot life ends when coating becomes too viscous to use.   Increased waste due to unused catalyzed material, cost of material and disposal of hazardous waste.
Minimal crew sizes usually achieve same productivity as full blown crews and most always finish well ahead of schedule.   Lower skilled labor can be hired to achieve same result with the HRCSA system being so user friendly and surface tolerant.   No hazardous waste stream from the HRCSA coating system.   Empty pails with dried coating can be sent to landfills.   Empty drums with “free” sign taped to them are always put to use by the general public.	The constraints associated with multi-component, multi-coat systems usually end on schedule with larger crews, more hazardous waste to manage end of project.   Longer time lines = More labor More equipment rental costs Greater demurrage costs Increased risks of penalties.
	A contractor’s greatest expenses lie with manpower, equipment rentals, mobilization costs and hazardous waste management.
