Standard pressure washing runs $0.10-$0.30 per sq ft. Paint stripping and epoxy removal runs $1.00-$6.00 per sq ft -- and large commercial jobs hit minimums of $500-$2,000 before you even start. If you have the right equipment and know the technique, this is some of the highest-margin specialty work in the industry.

The Quick Answer

Pricing for pressure washing paint and epoxy removal:

Hydroblasting (general coatings): $1.00 - $2.50 per sq ft with labor
Epoxy floor removal (labor only): $1.50 - $6.00 per sq ft
Full epoxy removal (labor + disposal): $2.50 - $8.50 per sq ft
Minimum job charges: $350 - $2,000
Wet sandblasting comparison: $1.30 - $3.50 per sq ft (higher cost, more mess)

These rates are 5-10x what a standard driveway cleaning pays. But the PSI requirements and safety rules are different. Here's what you need to know.

PSI Requirements by Job Type

Not all paint removal is the same. The PSI you need depends on what you're removing and what's underneath it.

General surface prep (removing loose paint): 1,200 - 3,000 PSI
Stripping bonded paint from concrete or metal: 4,000+ PSI
Epoxy floor coating removal: 4,000 - 6,000 PSI (may need chemical pre-treatment)
Ultra-high pressure (UHP) waterjetting for industrial coatings: 30,000 - 40,000 PSI

The AMPP (formerly NACE) defines UHP waterjetting as 30,000 PSI or above. That's industrial territory -- bridges, structural steel, marine vessels, and parking garage deck restoration. Most contractors operate in the 4,000-6,000 PSI range for paint and epoxy work on commercial buildings.

Coatings You Can Remove

High-pressure washing is effective on a wide range of coatings and surfaces:

Epoxy floor coatings: garages, warehouses, industrial slabs
Paint on concrete, masonry, and metal: building exteriors, parking structures
Rust and oxidation on steel: bridges, railings, equipment
Old coatings on structural steel: bridges and industrial facilities
Parking lot line striping: removal before repainting
Graffiti: especially effective on porous surfaces that resist chemical removal alone

Equipment: What You Need

Your standard residential pressure washer won't cut it here. Paint stripping requires commercial-grade equipment.

For Commercial Paint Stripping (4,000-6,000 PSI)

Hot water commercial unit: $3,000 - $8,000 purchase price
Equipment rental for occasional jobs: $200 - $500 per day
Surface prep nozzles: 0-degree pencil jet or 15-degree for concentrated blasting

For UHP Waterjetting (30,000+ PSI)

Industrial UHP rigs: $50,000 - $150,000+ (specialized industrial equipment)
Robotic systems for large projects: Cover 3,200-4,300 sq ft per 8-hour shift

Most contractors start with the 4,000-6,000 PSI range and rent equipment for larger jobs until they have enough volume to justify owning a UHP rig.

Safety: This Is Not Standard Pressure Washing

At 4,000 PSI, you can inject water under your skin. People have lost fingers and hands to injection injuries at pressures far lower than this. OSHA and AMPP safety rules are not optional.

PPE required: Full face shield, waterproof overalls, metatarsal boots, heavy-duty gloves, hearing protection
Exclusion zone: 50+ foot radius at UHP levels for flying debris
Lead paint rules: Pre-1978 surfaces may contain lead -- EPA regulations apply to containment and disposal
Wastewater: Paint waste and stripping runoff must be contained and disposed of properly
Certification: WJTA (WaterJet Technology Association) certification is recommended and sometimes required by commercial clients

The safety requirements are real. Build the cost of proper PPE and containment into every bid. Skipping it isn't worth the liability.

When Rental Makes More Sense Than Owning

If you're doing paint stripping work occasionally, renting at $200-$500 per day often beats owning a $5,000+ unit. The break-even math: if you're doing fewer than 15 days of paint stripping work per year, rent. Above that, buy.

For UHP waterjetting, the calculus is different. A $100,000 rig needs consistent commercial contracts to justify the investment. Many contractors subcontract UHP work to specialists and mark it up instead of owning the equipment.

Where to Find This Work

Paint stripping and epoxy removal clients are different from residential homeowners:

Commercial flooring contractors: Need epoxy removed before resurfacing
Property managers: Parking decks, building exteriors, repainting prep
Industrial facilities: Warehouses, manufacturing plants, equipment cleaning
Municipal and DOT contracts: Bridge maintenance, infrastructure restoration
Painting contractors: They need surfaces prepped -- be the sub they call

Bottom Line

Paint stripping and epoxy removal is niche work that pays 5-10x standard pressure washing rates. The equipment investment and safety requirements are real barriers -- but those same barriers keep competitors out. If you can handle commercial surface prep jobs, you're competing in a market with less price pressure and bigger checks.
