Surfaces previously coated with a splash-zone coating system shall be sweep blasted or disc sanded to roughen the surfaces. Surfaces shall be thoroughly cleaned of dust and contamination before new coatings are applied.

Surface blasting to white metal shall extend a minimum of 6” beyond the area to be coated during the same day. Surface blasting to white metal shall continue a minimum of 1” into adjoining previously coated surfaces. The edges of the previous coating shall then be feathered.

No acid washes, cleaning solutions, solvents, or inhibited washes intended to prevent rusting shall be applied to surfaces after abrasive blasting and prior to the first primer coat application.

In the event of abrasive cleaning being impractical or unsuitable, steel surfaces may be mechanically cleaned using power tools such as wire brushes, needle guns, etc. Should this be necessary, power tool cleaning shall be performed according to SSPC-SP-3 at the time of coating.

3.2.5.5 Special Considerations

If surfaces on machinery and equipment cannot be abrasive blasted without damage or contamination of moving parts or other critical surfaces, the surfaces shall be solvent cleaned as specified in SSPC-SP-1. After solvent cleaning, the surfaces shall be cleaned by hand and / or power tool as specified in SSPC-SP-2 surface Preparation Specification – hand Tool Cleaning

Surfaces that have already received an equipment manufacturer’s coating system, which is approved in writing by the COMPANY Project manager, shall be solvent cleaned as specified by SSPC-SP-1.

If the equipment manufacturer’s coating system was not an approved coating or brand, it shall either be removed to bare metal and recoated in accordance with this specification, or with COMPANY approval it may be top coated. If top coated, the surface shall be solvent cleaned per SSPC-SP-1 and primed with a suitable universal primer. The intermediate and finished coats of System IV shall then be applied. The CONTRACTOR shall be fully responsible for compatibility between the equipment manufacturer’s prime coat, the universal primer and the intermediate coat.

3.2.6 General Coating Application

Coating shall be applied in accordance with the requirements established by this specification and the recommendations of the coating manufacturer. Any area not specifically covered shall be in accordance with the principles and guidelines set forth in the SSPC Manual.

In particular attention should be paid to thinning, mixing and curing times between subsequent coats. The solvent rub test shall be used to verify the




cure of inorganic zinc silicate primer prior to overcoating. Any brushing shall be carried out such that a smooth, uniformly thick coat is obtained. There should be no deep or detrimental brush marks. Paint shall be worked into all crevices and corners. Runs or sags shall be brushed out.

No coating shall be applied to surfaces that have not been prepared in accordance with the requirements of section 3.2.5.

Prior to coating, surfaces blasted to white metal shall be dust free. The surfaces shall be dusted preferably by dry brushing or by vacuuming with an industrial vacuum cleaner. Pressure air blowing is permitted if suitable precautions are taken to ensure that the air is free of moisture, oil, and other contaminants.

There is no restriction on blasting and painting of structural steel of areas adjacent to limits of plates, and as such CONTRACTOR may blast and prime up to the edge of the structural steel. Any weld areas shall be dressed back after painting 1”.

The initial primer coat shall be applied as soon as possible after preparation. In all cases the primer coat shall be applied during daylight hours on the same day the surface is prepared.

In general, intermediate and finish coatings shall be applied following final assembly of component parts. Surfaces shall be in the final configuration.

Any surfaces inaccessible for proper coating application and/or inspection shall be coated prior to final assembly. Specifically, flange faces and boltholes shall be coated prior to final installation. COMPANY representative will designate inaccessible areas.

Prior to applying a succeeding coat, all coatings shall be allowed to dry at site ambient conditions for at least the minimum time specified by the coating manufacturer and not longer than the maximum time for site ambient conditions.

No coating shall be applied over a previous coating that is not thoroughly dry.

Coatings shall be applied by brush to all crevices, corners, edges, and other hard-to-spray areas in accordance with 3.2.6.2.

The coating film thickness referred to in this specification shall be the dry film thickness (DFT) measured by a properly calibrated film thickness gauge and are minimum values.

All areas such as external corners and edges, welds, bolts, nuts and interstices (excluding galvanised surfaces) shall receive a “stripe” coat prior to application of the specified coat (excluding the inorganic zinc silicate primer) to ensure that these areas have at least the minimum specified film thickness and to ensure continuity of the coating. The “stripe” coat shall be ‘touch dry’ prior to coating with the specified coat.

All areas that will be subject to welding after painting shall be masked after blast cleaning. Masking shall preferably be with cloth or cloth tape and shall extend at least 2” on all sides of the intended weld area.

The contact surface of earthing bosses shall be masked after blast cleaning.

Nameplates shall be suitably masked before blast cleaning to protect from blasting abrasive and paint.




The cured coatings shall be visually free of pinholes, voids, bubbles, mud cracking and other “holidays”.

Each coat shall be in a proper state of cure or dryness before the application of the next coat. Material shall be dry for re-coating when an additional coat can be applied without the development of any detrimental film irregularities, such as lifting or loss of adhesion of the undercoat. Manufacturers instructions shall be followed.

When successive coats of the same colour have been specified, alternate coats shall be tinted, when practical, sufficiently to produce enough contrast to indicate complete coverage of the surface. When the material is the colour of the steel, or when the tinting of the final coat is objectionable, the first coat to be applied shall be tinted. The tinting material shall be compatible with the material and not detrimental to its service life.

Prior to the application of any coat of material all damage to previous coats shall be touched up with the specified coating. Damage prior to delivery of finish coating shall be reprimed and refinished.
