- Recommended Uses
Caliber Low VOC Primer is intended for industrial applications; either new build or maintenance. Caliber Low VOC Primer is suitable for application on properly sanded or sandblasted steel and for properly prepared galvanized or zinc coated substrates. This primer must be topcoated to achieve the best results.

- Well Service vehicles
- Drilling Rigs
- Cranes and Construction Equipment
- Waste and Recycling Industry
- Garbage Trucks
- Marine (above the water line)
- Mix Ratio
5 parts by volume of component A and 1 part by volume of component B. The recommended temperature when mixed is 68-77°F (20-25°C).
- Surface Preparation
Surface must be free of all contaminants such as dust, oil, grease and salt. It is recommended that all steel and other ferrous surfaces be sandblasted a minimum of SSPC- SP6 or mechanically sanded with 80 grit sandpaper. For optimal corrosion protection the surface should be sandblasted to SSPC-SP5 or SSPC-SP10 (White or Near White Blast).
- Application Method
Caliber Low VOC Primer can be applied using most spray painting systems, although electrostatic sprayers are not recommended. Apply 1-2 coats as required to achieve the desired film thickness. Allow sufficient flash time between coats especially with higher film builds applied (20-30 minutes). Agitation is not required while spraying; the zinc is fully suspended in the coating.

-
Note: Spraying viscosity and thinning will depend on ambient conditions, spray equipment used, and the desired surface finish. If required, recommended spraying viscosity is achieved by reducing with one of the following Endura Low VOC Epoxy reducers. These will maintain VOC compliance of Caliber Low VOC Primer.
VOC content of the following Reducers:
[FTH0016] Low VOC Epoxy Reducer – Regular
[FTH0027] Low VOC Epoxy Reducer - Slow
- Film Build
Caliber Primer has a recommended film build thickness of:
WFT (Unreduced) 5.5 - 9.0 mils 140 - 230 microns
DFT 3 - 5 mils 76 - 127 microns
The recommended dry film thickness is above the blast/sanding profile.
Theoretical coverage at 1.0 mil (25 microns) DFT: 883 ft² per gallon at 100% transfer efficiency.
- Dry Times
20°C 30°C 40°C Top Coat 3 Hours 2 - 3 Hours 1 - 2 Hours Full Cure 7 - 9 Days 5 - 6 Days 3 - 4 Days Note: Dry Times are subject to ambient conditions (temperature and humidity), good airflow and film build of primer. For best results surface temperature must be 86°F (30°C) or less before top coating. Maximum re-coat window without sanding is 3 Days at 68°F (20°C) Recommended Sanding 180 – 220 grit after the topcoat window has been exceeded.
- Top Coating Infomation
Caliber Low VOC Primer can be topcoated with the entire range of Endura topcoat products.
- Clean Up
Clean all equipment immediately after use with Endura High Strength Gun Wash, Endura epoxy reducer or Endura EX-2C thinner.

Safety & Health
- Environmental Conditions
For optimum coating performance, product, substrate and ambient temperature should be between 68°F-77°F (20°C-25°C). To prevent condensation during application the surface temperature must be 5°F (3°C) or more above the dew point at all times.
