- Recommended Uses
EP Sandable Low VOC Primer is intended for industrial applications; either new build or maintenance. EP Sandable Low VOC Primer is suitable for application on steel, aluminum and fiberglass substrates. This primer must be topcoated to achieve the best results.
Industries:
- Oilfield & Energy Services
- Well Services Equipment
- Cranes and Construction Equipment
- Trailers
- Waste and Recycling Industry
- Garbage Trucks
- Marine (above the water line)
- Mix Ratio
- 3 parts by volume of component A
- 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 to a minimum of SSPC-SP6 or mechanically sanded with 80 grit sandpaper.
- Application Method
EP Sandable Low VOC Primer can be applied using most spray 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).
- Spray Gun Setup
Feed Type Fluid Tip Application Pressures (Heel of Gun) Fluid Delivery Siphon Feed 1.6 - 2.0 mm 40 - 50 psi Gravity Feed 1.6 - 2.0 mm 30 - 40 psi Pressure Feed 1.4 -2.0 mm 50 - 60 psi 10 - 14 oz/min Air Assist Airless 9 - 17 Thou 1000 - 1800 psi Airless 11 - 15 Thou 1700 - 3000 psi - Spray Viscosity
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 EP Sandable Low VOC Primer.
VOC content of the following Reducers: (0g/l, 0 lbs/gal)
[FTH0016] Low VOC Epoxy Reducer - Regular
[FTH0027] Low VOC Epoxy Reducer - Slow
- Film Build
EP Sandable Low VOC Primer has a recommended film build thickness of:
WFT (Unreduced) 6.0 - 10.0 mils 152 - 254 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: 820 ft² per gallon at 100% transfer efficiency.
- Dry Times
20°C 30°C 40°C Top Coat 1 - 2 Hours 1 Hours 45 Minutes To Sand Optimal - 8 hours, Minimum - 4 Hours Note: Dry Times are subject to ambient conditions (temperature and humidity) and 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 7 days at 68°F (20°C). Recommended mechanical sanding with 180 – 220 grit after the topcoat window has been exceeded.
Note: If the primer is allowed to sit for an extended period without being topcoated, the surface must be kept clean of contaminants to avoid any topcoat issues.
- Top Coating Infomation
EP Sandable 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.
