Substrate Protection

Surface type • application method • dwell time • pH readings

Surface Treatment Summary

Surface	Material	Method	SH Concentration	Dwell Time	pH Entry	pH Exit	Result
Lap Siding	Fiber cement, painted flat white/gray	Soft Wash (downstream inject)	0.5% as applied	4 min 30 sec avg	7.1	7.0	PASS

Method Detail

Application Method Downstream injection via 12-volt soft wash pump system; 4-nozzle fan tip array at 100–150 PSI low-pressure delivery

SH Stock 12.5% sodium hypochlorite (bulk supply); downstream-diluted to 0.5% as-applied concentration

Surfactant Ratio GreenClean Pro Bio-Surfactant at 1 oz per gallon of mix; aids cling and dwell on vertical fiber cement surfaces

Dwell Time 4 min 30 sec average per panel run; monitored via stopwatch per crew member. No surface allowed to dry before rinse.

Rinse Pressure Low-pressure freshwater rinse at 150 PSI via garden hose attachment; neutralizer pass at same pressure

pH Target Range 6.5–9.0 (municipal discharge standard, Demo District stormwater ordinance)

Surface Compatibility 0.5% SH confirmed safe for fiber cement (manufacturer HardiePlank guidance: <1% SH acceptable); no paint etching, no oxidation risk observed

pH Reading Log

Reading Point	Location	Time	pH Value	Target Range	Status
Entry (pre-application)	Tap water supply / hose bib Unit 840	7:08 AM	7.1	6.5–9.0	PASS
Mid-job	Runoff collected at building base Unit 820	9:15 AM	7.2	6.5–9.0	PASS

All chemicals were applied at concentrations within manufacturer-specified and regulatory limits. Sodium hypochlorite was applied at 0.5% as-applied concentration (downstream-diluted from 12.5% stock). All stormwater controls were in place prior to application. Runoff pH was verified at 7.0 (within municipal discharge standards) before drain plugs were removed. HOA Approval #RTA-2026-047 was obtained prior to commencement of work. This report is accurate and complete to the best of my knowledge.
