Module 7 — Flatwork: Stripe-Free Results (Lesson)

This trade is hard work, but it’s not complicated forever. We’re going to keep it simple: protect first, run a repeatable process, and document everything. You don’t need perfect gear on Day 1 — you need good habits and a clear next step. If you’re unsure, you stop, test, and reset expectations before you touch the surface.

What you’re doing today

You’re learning how to clean flatwork evenly — stripe-free — without etching and without leaving the edges dirty.

Why this matters

Anyone can make concrete look “kind of better.”

Professionals deliver:

• even cleaning
• clean edges
• no etching

Flatwork is also one of the easiest ways to earn trust fast because the before/after is obvious.

Tools & materials (minimum viable)

• Pressure washer with enough flow for your surface cleaner (GPM matters)
• Surface cleaner sized for your machine
• Wand for edges
• PPE: eye protection + boots
• Hose + water supply
• Phone camera (Proof Pack)

Quick Start (the 60-second version)

1. Pre-condition photos
2. Clear debris
3. Pre-treat (if needed)
4. Surface clean with overlap
5. Edge work
6. Post-rinse + proof

Step-by-step workflow (foreman sequence)

1. Pre-condition photos
   • wide shot + worst spot close-up
2. Debris removal
   • rocks/sticks first (protects equipment and prevents streaks)
3. Pre-treat (when organic growth is present)
   • let chemistry do work so you don’t “chase stripes”
4. Surface clean
   • steady pace, overlap passes
   • don’t stop in one spot
5. Edges + corners
   • wand the edges last so they match the field
6. Final rinse + inspection
   • check for lines while still wet
7. Proof Pack + closeout
   • after photos + any exceptions

Decision points

• If you’re getting stripes:

  • slow down and overlap more
  • verify your surface cleaner is matched to your flow

• If the surface is coated or delicate:

  • change method before you cause damage

Common mistakes + fixes

• Moving too fast
  • Fix: overlap and steady pace.
• Starting with edges and then “double working”
  • Fix: clean field first, then edges to match.
• Etching from too much aggression
  • Fix: chemistry + time beats brute force.

What good looks like

• Even finish
• No zebra lines
• Edges match the field
• No damage

How to prove it (Proof Pack)

Minimum shots:

• before: wide
• before: worst spot
• after: same angle wide
• after: close-up of the worst spot

SOP

• QA checklist:

Do this next (assignment)

• Clean a small test area and practice overlap until stripes disappear.
• Capture a Proof Pack set.
