Environmental Perimeter

BMP checklist, weather conditions, and drain protection measures

BMP Checklist — 5/5 Complete

✅ Work perimeter inspected; concrete curb dammed to contain runoff before application commenced PASS

✅ Reclaim squeegee system deployed; all rinse water directed toward collection point, not storm system PASS

✅ EIFS joint sealant inspected pre-service; all joints confirmed intact, no cracking or delamination observed PASS

✅ SDS sheets on-site for all three chemicals; PPE donned and verified prior to application PASS

✅ No citrus-based or D-limonene-containing cleaners used; EIFS manufacturer restriction acknowledged and complied with PASS

Weather Conditions at Time of Service

Temperature 68°F (20°C) — ideal soft wash conditions; no freeze risk

Sky Conditions Clear; no cloud cover; no precipitation during service window

Wind Speed / Direction 6 mph SE — light crosswind; standard application technique adjusted for minor drift; no vegetation downwind requiring masking

Relative Humidity 45% — low humidity; dwell time extended to 8 min to compensate for faster evaporation on EIFS surface

Drain Protection & Disposal

Containment Method Concrete curb dammed using water-inflated bladder barriers along two perimeter sides. Reclaim squeegee used to push rinse water to central low point for vacuum recovery.

Wastewater Disposal All collected rinse water vacuumed and discharged to sanitary cleanout on property, confirmed accessible pre-service. No discharge to storm system or street gutter.

Spill Standby Equipment Wet vac (8-gallon), citric acid neutralizer spray, absorbent granules (1 bag), EIFS-compatible sealant touch-up kit on truck for post-service joint re-inspection

<\!-- Section 2: Substrate Protection -->

🏛

Substrate Protection

EIFS surface specification, manufacturer compliance verification, dwell log, and pH records

Manufacturer Warranty Compliance — SH Concentration

🛠️

EIFS Manufacturer Restriction: Maximum SH concentration of 0.5% specified in manufacturer warranty documentation. Operator applied 0.3% — providing a 40% compliance buffer below the warranty limit. This protects the manufacturer warranty and demonstrates conservative, surface-appropriate chemical selection.

Manufacturer Maximum (SH)

0.5%

Upper limit for warranty preservation

Operator Applied (SH)

0.3%

40% below manufacturer limit — warranty intact

Surface Specification

Surface Type 🏛 EIFS / Synthetic Stucco Exterior Insulation Finish System; polymer-based finish coat over EPS insulation board

Cleaning Method Soft Wash (Low-Pressure) Applied at 500–800 PSI max; manufacturer limit is 1,200 PSI — operator remained well within spec

Contaminants Removed Algae colonies (green and black), mildew streaking, atmospheric dust accumulation typical of Texas panhandle climate (fine particulate, pollen)

Pre-Service Inspection All EIFS joint sealants inspected for cracking, delamination, or moisture infiltration. All joints intact. No soft spots detected on wall system by firm-press test. Inspection documented and signed before chemical mix prepared.

Restricted Products D-limonene, citrus terpene, and alkaline (high-pH) degreaser products prohibited per EIFS manufacturer spec. None used or present on site for this job.

Application Parameters

Parameter	Value	Notes
SH Concentration	0.3%	Downstream injection from 12.5% stock; diluted inline. Mfr. max: 0.5%.
Surfactant	1.5 oz / gal	Bio-Clean EF Surfactant — EIFS-rated, non-ionic; verified compatible with polymer finish coats
Dwell Time	8 min 00 sec	Extended dwell protocol for low-concentration SH; compensates for 45% humidity environment
Application Pressure (SH Pass)	<100 PSI	Soft wash nozzle only; no fan tip; no direct-impact pressure on EIFS face
Rinse Pressure	500–800 PSI	Post-dwell rinse at 24" standoff; well within mfr. max of 1,200 PSI
Surface Area Treated	4,800 sq ft	Full building perimeter, all four elevations, ground level to 28 ft

Volume Summary

Mix Type	Gallons Applied	% of Total
SH Mix (0.3% + surfactant)	70 gal	78%

pH Verification — Entry & Exit

pH Entry 7.0 Acceptable range: 6.0 – 9.0 ✅ In Range

pH Exit 7.3 Acceptable range: 6.0 – 9.0 ✅ In Range

pH measured at curb collection point using calibrated ATC digital pH meter. Exit pH delta of +0.3 from entry is within normal range and consistent with complete neutralization of 0.3% SH residual. Citric acid neutralizer rinse confirmed effective.

Chemical Documentation

SDS cards and application log for all chemicals used on this job

Safety Data Sheets — On-Site

⚠️

Sodium Hypochlorite 12.5% Solution SDS ON SITE

Applied concentration: 0.3% (diluted via downstream injector; EIFS manufacturer max 0.5%)
GHS Hazard class: Oxidizer, Corrosive, Aquatic Hazard — Acute Cat. 1
PPE required: Nitrile gloves (min 8-mil), chemical splash goggles, splash-resistant apron
EIFS compatibility note: Cleared for use at or below 0.5% per EIFS manufacturer technical bulletin TB-041; operator used 0.3% for additional compliance margin
Spill response: Dilute with large volume of water; neutralize with citric acid; do not allow to enter storm drain

⚗️

Bio-Clean EF Surfactant SDS ON SITE

Mix rate applied: 1.5 oz per gallon of SH mix
Chemistry: Non-ionic surfactant blend; EIFS-rated; free of D-limonene, citrus terpenes, and alkaline boosters
EIFS approval status: Listed on EIFS manufacturer's approved cleaning products list (ACL-2024); preserves polymer finish coat integrity
GHS Hazard class: Not classified as hazardous (non-ionic, low-hazard formulation)
Biodegradability: >95% biodegradable within 28 days per OECD 301F

💧

Citric Acid Neutralizer (Post-Rinse, 5% Solution) SDS ON SITE

Application: Added to final rinse water at 1 oz/gal concentration; ensures pH neutralization at collection/drain point
GHS Hazard class: Mildly irritating; non-corrosive at 5% concentration; not regulated as hazardous material in transport
PPE required: Standard nitrile gloves; no respirator required at working concentration
EIFS compatibility: Compatible with polymer finish coats; slightly acidic formulation assists in SH neutralization without risk of EIFS surface etching at working concentrations
