Phoscrete Formula Comparison Table
*Working and traffic-ready times based on 70°F (21°C); actual times may vary with temperature and admixtures.
Formula Selector Guide
1. Choose by Repair Type:
-
Horizontal/Castable Repairs:
- For fastest set and return to service: F1-HC
- For extended working time or large repairs: F3-HC
-
Vertical & Overhead Repairs:
- For fast-setting, minimum thickness required: F1-VO
- For feather finishes and/or spray/shotcrete: F3-VO
-
Rebar Corrosion Mitigation:
- Directly coat steel rebar before patching: RC
-
Challenging Substrates (e.g., carbonation, reactive aggregate):
- Apply primer first: PR
-
Surface Protection & Durability:
- Use as admixture (in F3) or curing spray: Endure
2. Consider Project Conditions:
- Cold Weather (down to -5°F/-20°C):
- Use F1-HC or F1-VO (condition activator, use Fast-Set admixture if needed)
- Warm/Hot Weather:
- Use F3 formulas with chilled activator and/or Slow-Set admixture
3. Application Methods:
- Hand Pack or Trowel: Any formula, but F1-VO and F3-VO are designed for easy overhead/vertical placement
- Bucket Mix: All formulas
- Mortar Mixer: F1-HC, F3-HC, F3-VO
- Pump/Shotcrete/Spray: F3-VO (recommended); F3-HC for pumping overlays
Common Scenarios & Recommendations
- Emergency road/airport repair: F1-HC for rapid set and traffic reopening in under an hour
- Bridge column repair: F3-VO for vertical surfaces; feather edges possible
- Corroded rebar in spall: RC as direct coating, then patch with F3-HC or F1-HC
- Large overlay or expansion joint header: F3-HC for extended working time and pumpability
- Reactive or carbonated substrate: Prime with PR before patching
