Rust Preventing Primer
Pioner Primer is a rust preventing primer based on a chlorinated polymer.
As a primer on steel and concrete structures exposed to moderate environments. Quick drying and may be used at low

All surfaces should be clean, dry and free from contamination. The surface should be assessed and treated.
Cleanliness: Blast-cleaning to Sa 2½ (ISO-8501-1:07). Power tool cleaning to min. St 2 may be
acceptable, subject to exposure conditions.
Clean, dry and undamaged approved shopprimer.
Clean, dry and undamaged compatible primer.
The coating may be used on other substrates.
Condition during application
The temperature of the substrate should be minimum 3ºC above the dew point of the air, temperature and relative
humidity measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure
Spray Use airless spray
Brush Recommended for touch-up purposes.
Roller May be used for small areas but not recommended for first primer coat, however when using roller
application care must be taken to apply sufficient material in order to achieve the specified dry film
Mixing ratio (volume) Single pack.
Thinner/Cleaner Honest joy Thinner No. 7
Guiding data airless spray
Pressure at nozzle 15 MPa (150 kp/cm² 2100 psi)
Nozzle tip 0.46-0.69 mm (0.018-0.027")
Spray angle 40-80°
Filter Check to ensure that filters are clean
Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be
affected correspondingly. The figures given in the table are typical with:
* Good ventilation (Outdoor exposure or free circulation of air)
* Typical film thickness
* One coat on top of inert substrate
Substrate temperature 5°C 10°C 23°C 40°C
Surface dry 40 min 30 min min 15 min
Through dry 10 h 8 h 5 h 3 h
Dry to recoat, minimum 4,5 h 3,5 h 2 h 1,5 h
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or
longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and
mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special
conditions could be included.
Typical paint system
Pioner Primer 2 x 75 μm (Dry Film Thickness)
Pioner Topcoat 1 x 50 μm (Dry Film Thickness)
Other systems may be specified, depending on area of use
