Chemical Application Log

Products used, dilution ratios & volume documentation — SH 1.5% · Elemonator (0.5 oz/gal)

Chemical Product	Volume Applied	Notes / Dilution
Sodium Hypochlorite 12.5% (diluted to 1.5%) ⚠️ See SDS below · OSHA HazCom 2012	22.00 gal	Soft wash — low-pressure application to avoid surface etching
Elemonator Non-ionic Surfactant ⚠️ See SDS below · OSHA HazCom 2012	2.50 gal	0.5 oz/gal, improves dwell contact on porous limestone
F9 BARC (Calcium Carbonate Eliminator) ⚠️ See SDS below · OSHA HazCom 2012	4.00 gal	Pre-treat for efflorescence; rinsed before SH application
