Technical Pressure Washing Standards in Sandy Springs

Pressure washing is not a one-setting process. Proper results — without surface damage — depend on controlled PSI, sufficient water volume (GPM), appropriate dwell time, and responsible recovery practices. These standards vary significantly by surface type and use case. Understanding and strictly applying these technical standards is what separates professional pressure washing from surface-damaging shortcuts — and it’s why Proline is trusted as the leading pressure washing company in Sandy Springs.

High Pressure Surface Cleaner - Concrete Driveway

Residential Pressure Washing Surfaces in Sandy Springs

  • Concrete driveways

  • Concrete sidewalks & walkways

  • Concrete patios

  • Pool decks (concrete or textured concrete)

  • Concrete stairs & landings

  • Curbs & concrete gutters

Typical Surfaces:
Driveways, sidewalks, patios, pool decks, stairs, retaining walls, pavers

Operating Ranges

  • PSI: 2,500 – 3,200 PSI

  • GPM: 4.0 – 6.5 GPM

  • Nozzle Selection: 25°–40° fan tips (surface cleaners preferred for flatwork)

Dwell Time

  • 5–15 minutes, depending on:

    • Embedded traffic film

    • Organic staining depth

    • Concrete porosity and age

  • Dwell time is used to reduce mechanical pressure, not replace it.

Recovery & Runoff Control

  • Residential jobs typically rely on managed directional runoff

  • Water is routed away from:

    • Foundations

    • Garage thresholds

    • Landscaping beds

  • Sensitive areas may require temporary berming or water diversion

Risk Management

  • Excess PSI can:

    • Etch concrete

    • Expose aggregate

    • Strip joint sand from pavers

  • Proper GPM allows cleaning with flow instead of force

Sodium Hypochlorite (SH) Use in Professional Pressure Washing

 

Standards for Sandy Springs

In professional pressure washing, SH is used as a cleaning aid — not a substitute for pressure or flow. Correct dilution allows contaminants to be released from the surface so they can be rinsed away with lower mechanical stress.

Key principle:
Higher SH does not equal better cleaning — it increases risk.

​

Residential Pressure Washing — Typical SH Ranges

Common Surfaces:
Concrete driveways, sidewalks, patios, pool decks, retaining walls

Typical Working SH Strength

  • 0.5% – 1.0% SH (post-mix at surface)

Why This Range Matters

  • Removes:

    • Organic growth

    • Light mildew staining

    • Traffic film

  • Allows cleaning at lower PSI, reducing:

    • Etching

    • Aggregate exposure

    • Paver joint erosion

Risks of Over-Application

  • Surface bleaching

  • Premature concrete drying and micro-fracturing

  • Damage to adjacent landscaping

  • Accelerated oxidation of nearby metals

Residential Pressure Washing Standards

Commercial Pressure Washing Surfaces in Sandy Springs

  • Parking lots (concrete)

  • Parking decks & ramps

  • Dumpster pads & trash enclosures

  • Breezeways & common-area concrete

  • Commercial building flatwork

  • Loading docks

  • Concrete stairs & entryways

  • Curbs & concrete gutters

  • Retail sidewalks & storefront concrete

  • HOA common-area hardscapes

  • Gas station pads (concrete only)

  • Tennis courts & sport courts (hard surface)

Commercial Pressure Washing — Typical SH Ranges

 

Common Surfaces:
Parking decks, dumpster pads, breezeways, storefront concrete, HOA common areas

 

Typical Working SH Strength

  • 0.75% – 1.5% SH (post-mix at surface)

 

Why This Range Matters

  • Breaks down:

    • Heavier traffic oils

    • Food grease residue

    • Biological buildup in shaded areas

  • Reduces the need for:

    • Excessive PSI

    • Multiple aggressive passes

 

Operational Considerations

  • Requires controlled dwell time

  • Must be paired with:

    • Thorough rinsing

    • Proper runoff management

  • Often combined with surfactants to improve cling and penetration

 

Risks of Over-Application

  • Surface discoloration

  • Accelerated concrete wear

  • Odor complaints in high-traffic environments

  • Increased regulatory exposure if runoff is unmanaged

Industrial Pressure Washing Surfaces in Sandy Springs

  • Warehouse floors (industrial concrete)

  • Manufacturing & distribution facility concrete

  • Heavy-duty loading zones

  • Industrial equipment pads (concrete)

  • Transfer station concrete

  • Utility & service yard concrete

  • Commercial truck staging areas

  • High-traffic concrete aprons

Industrial Pressure Washing — Typical SH Ranges

Common Surfaces:
Warehouse floors, loading zones, equipment pads, truck staging areas

 

Typical Working SH Strength

  • 1.0% – 2.0% SH (post-mix at surface)
    (Used selectively and condition-dependent)

 

Why This Range Matters

  • Industrial contaminants often include:

    • Rubber transfer

    • Petroleum residue

    • Organic contamination from moisture exposure

  • SH assists in organic breakdown only — not petroleum removal
    (other detergents are often required)

 

Recovery & Safety Requirements

  • Mandatory containment and recovery

  • Neutralization may be required prior to disposal

  • Application is limited to trained operators only

 

Risks of Improper Use

  • Surface degradation

  • Slip hazards

  • Environmental violations

  • OSHA exposure concerns

A Message From Our Owners

At Proline, Sandy Springs isn’t just part of our service area — it’s home. This is where our business first took shape many years ago, long before we had professional trucks, advanced equipment, or a growing team behind us. Back then it was just hard work, a passion for helping homeowners feel proud of their property, and a belief that if we showed up with honesty, kindness, and real craftsmanship, the community would trust us.

​

Turns out, Sandy Springs did more than trust us — it helped build us.

To every homeowner, neighbor, and small business that welcomed Proline into your driveways and onto your porches: thank you. Your support is the reason we’ve grown, improved, and earned a reputation for quality and integrity throughout the Atlanta area.

Today, we still operate with the exact same values we began with right here in Sandy Springs:


• Treat every property like our own
• Always communicate clearly and respectfully
• Do the job the right way, never the easy way
• Leave every customer feeling genuinely cared for
