Module 7 — Flatwork: Substrate Matrix + Expectations (Lesson)

What you’re doing today

You’re learning how to change method based on what the flatwork actually is.

Concrete ≠ pavers ≠ coated surfaces.

Why this matters

Substrate determines risk.

If you treat everything like bare concrete, you’ll eventually damage something expensive.

Tools & materials (minimum viable)

• Phone camera (Proof Pack)
• A simple expectation script (old stains ≠ organic growth)

The substrate matrix (simple)

Bare concrete (most common)

• Usually responds well to surface cleaning + proper chemistry

Pavers / stone

• Higher risk of joint sand disruption
• Expectations matter

Coated / painted surfaces

• High damage risk
• Often requires a different lane (and different pricing)

FIGURE (pressure vs flow mindset)

Step-by-step: expectation setting (foreman simple)

1. Call out the difference between:
   • organic growth (cleanable)
   • old stains / wear (may improve but not disappear)
2. Confirm what “success” means before you start.
3. Document pre-condition.

Decision points

• If the surface looks coated:

  • slow down and confirm before cleaning

• If you’re facing a rust stain:

  • treat it as chemistry, not pressure — don’t turn a small spot into a bigger repair

• If stains are old:

  • set expectations in plain English

Common mistakes + fixes

• Promising stain removal without testing
  • Fix: test spot + expectations first.

What good looks like

• Customer understands “improved vs removed”
• You have proof photos of before condition

SOP

Do this next (assignment)

• Identify 3 flatwork types at a property (concrete/pavers/coated).
• Write one expectation sentence for each.
