The 7-Point Epoxy Contractor Bid & Warranty Checklist (2026)

Require these 7 written specifications on your estimate to prevent delamination, acid-wash shortcuts, and voided hydrostatic moisture warranties.

Mandatory Written Scope Specifications

  1. Planetary Mechanical Diamond Grinding (ICRI CSP-2 to CSP-3): Reject acid-etching or pressure washing.
  2. Hydrostatic Moisture Vapor Testing (ASTM F1869 / F2170): Verify whether moisture above 3 lbs MVER is covered or requires a moisture-mitigating primer.
  3. 100% Solids Base Coat vs. Solvent/Water-Borne Dilutions: Confirm the exact manufacturer product data sheet (PDS) and total dry film thickness (28–35 mils for full flake).
  4. Full Broadcast ("To Rejection" @ 0.12 lbs/sf) vs. Partial Chip Sprinkle (0.02 lbs/sf): Full broadcast consumes ~55–65 lbs of vinyl chip per 2-car garage.
  5. Aliphatic Polyaspartic Topcoat: Prevents UV yellowing at the garage door apron or outdoor patio.
  6. Elastomeric Polyurea Crack & Joint Fill: Rigid polyester fillers crack under thermal slab movement.
  7. Labor + Material Delamination Warranty: Ensure re-grinding labor is covered, not just replacement resin buckets.
