Painting Methodology
Ensure that painting is carried out for surface preparation in the following sequence :-
- 2 coats primer
- 2 coats finish paint
Coating:
Each coat shall be applied uniformly over the entire surface.
Holidays, run, sags, and drips shall be avoided. If they occur, they shall be removed and the surface recoated.
Each coat shall be allowed to dry for the time specified by manufacturer before application of any succeeding coat.

The time interval between applications of coats must not exceed that specified by the manufacturer.
Coatings shall be continuous, i.e. free of pin holes, voids, bubbles and other defects.
Application of coating system for galvanized steel:
Apply a coat of two components Epoxy Paint. Allow to dry for minimum 2-3 Hours (20 degree centigrade), 1 hour (40 degree C) may be diluted 5-10% with Thinner.
Apply 1st coat of Maestro Gloss Enamel by conventional spray and allow to dry for min. 4-5 hrs 40 degree C. May be diluted 5% with Thinner.
Apply final coat of Maestro Gloss Enamel as mentioned above. Allow to dry for min. 4-5 hrs.
Where application is to be carried out by brush, brushes shall be of a type and quality which permit proper application of the material.
No extending handles shall be used on brushes. Paint shall be worked into all corners and crevices.
When coatings are to be applied by roller these shall be of a type and quality which permits proper application of the material . Extension handles of more than 1 metre shall be used.
Specified film thickness for coating shall be strictly observed.
Film thickness shall be checked with appropriate film thickness gauges furnished by the contractor.
Please find below the parameters.
PRIMER: Indicated film thickness, dry 50 micron (2 coats). Indicated film thickness, wet 125 microns (2 coats).
PAINT: Indicated film thickness, dry 30 microns (2 coats). Indicated film thickness, wet 73 microns (2 coats).
