JENOSEEL®

JENOSEEL - STANDARD SPECIFICATION

 

A typical specification for the protection of steel using Jenoseel Plus, where long-term durability is required.

 

Procedure

1. Mechanical preparation - Remove all scale and heavy rust by scraping, chipping, needle gunning or whatever technique is appropriate. Scrape and wire brush the surface to ST3 ISO 8501-1 1988 standard. Any rough welds, edges etc. should be smoothed. The use of needle guns around bolt heads, joints etc is recommended. Do not use grinders. Wire-brushing on its own will not generally be sufficient on heavy rust. After removal of dust, the 'peaks' should show a metallic sheen. All existing treatments must be thoroughly abraded to remove all loose matter (paying particular attention to loose edges), and to provide a good mechanical 'key'.

 

2. If blasting, blast to SA2 standard. If wet blasting, do not use inhibitors.

 

3. If chemical or salt contamination is suspected, wash thoroughly with towns water (high-pressure washing is recommended). Heavy grease build-up should be mechanically removed before using degreaser.

 

4. Before coating, the surface must be clean, dry, sound and well ‘keyed’. The ‘peaks’ should show white metal.

 

5. 1st coat Jenoseel Plus - stir very thoroughly, and brush apply evenly at a wet film thickness of 78 microns (typically 8M2/Litre). Leave 10/15 minutes minimum, 1 hour MAXIMUM before overcoating.

 

6. 2nd coat Jenoseel Plus - apply second coat in similar manner. Leave overnight  (no maximum, although surface may need cleaning and re-priming if left for extended period).

 

7. Apply selected finish coats.

 

Notes

 

For large areas, Jenoseel Plus Brown is available to special order to help differentiate between coats.

 

1. Drying times are at 20ºC, and with good air flow. Poor air flow will extend these times.

 

2. If, after preparation only isolated areas of rust are revealed, spot priming with two coats of Jenoseel is acceptable. If larger areas, prime overall.

 

3. Stripe coat all edges, bolts, nuts, welds etc.

 

4. Do not apply at a steel-surface temperature below 5ºC on a falling thermometer, or above 25ºC on a rising thermometer. Relative humidity should be below 85%, and steel temperatures should be greater than 3ºC above the dew point.

 

5. The above should be read in conjunction with the manufacturer’s data sheets.
