7.0 SURFACE PREPARATION 7.1 General

Surface preparation shall be carried out by dry blast cleaning. Where dry blast cleaning is not feasible due to limited access, risk of damage to equipment, light gauge steel, proximity to electricity components or instrumentation, power tool cleaning shall be applied. This shall be followed by solvent cleaning prior to painting.

The NACE/SSPC Joint Surface Preparation Standards for dry abrasive blasting require solvent cleaning as per SSPC-SP1 to remove all visible contamination prior to abrasive blast cleaning. Solvent cleaning should be performed prior to any surface preparation procedures. If there is grease or oil on the surface then the surface preparation method can spread the contamination over the entire surface making it difficult to detect and then to remove. Once the surface preparation is completed then a final cleaning of any possible residue can be performed.

All necessary precautions are to be taken to ensure that previously painted areas are not damaged or contaminated by blasting operations. In particular no contamination of wet coated




surfaces by dust and abrasives shall be allowed and where damage or contamination does occur the affected area shall be blast cleaned again and the paint system made good.

Where the surface being prepared lies adjacent to a previously coated surface the blast cleaning shall overlap the coated surface by a minimum of 25 mm. Appropriate shields and screens shall be used to cover the remainder of the previously coated surface to prevent any possibility of damage or contamination of the coating.

After preparation of the substrate surface; a layer of primer is to be applied within 4 hours after blasting before any contamination or corrosion occurs.

7.2 Blast Cleaning

The color scheme is specified in Appendix 3 and shall be adhered to.

8.1.1 Application

All surfaces to be painted shall be dust free before application of the primer or first coat using clean dry air. Industrial vacuum cleaners shall be used in enclosed areas i.e. vessels and tanks. Test cleanliness is to be determined in accordance with ISO 8502-3: Preparation of Steel Substrates Before Application of Paints and Related Products - Tests for Surface Cleanliness - Part 3: Assessment of Dust on Steel Surface Prepared for Painting (Pressure-Sensitive Tape Method)

The paint manufacturer’s written recommendations with regard to mixing, thinning, application, method and equipment, drying times, curing times and over coating times of paints and coatings shall be followed. A mechanical mixer shall be used for mixing.

Paint or coating shall not be applied when the steel surface is at a temperature less than 30C above the dew point of the surrounding air or when the relative humidity of the air exceeds 80%.

When there is a likelihood that a change in the weather conditions may mean that the requirements for dew point or humidity, or any other stipulations of the manufacturer regarding the conditions for application of drying of paints, may not be fulfilled during the drying time, the paint shall not be applied.

Spray application shall be the preferred process, using airless spray guns, appropriate nozzle sizes and pressure ranges as recommended by the paint supplier. Each coat shall be applied uniformly and completely over the entire surface. All runs and sags shall be brushed out immediately. Beyond the recommended inter-coating period, sweep blasting shall be applied prior to the application of the first coat. Before spraying each coat, all areas such as corners, edges, welds, small brackets, bolts, nuts and interstices shall be pre-coated by stripe coating, to ensure that these areas have at least the minimum specified film thickness.

Where spray application is not feasible, paint shall be applied by brush. The brushing shall be done such that a smooth coat, as uniform in thickness as possible is obtained. There shall be no deep or detrimental brush marks. Paint shall be worked into all crevices and corners. Runs or sags shall be brushed out. Paint application by roller shall only be considered in exceptional cases i.e. for very large surface areas and after demonstrating that adequate control of film thickness can be achieved. It shall never be used for primer and sealer coats. Roller or brush application of glassflake epoxy shall be restricted to touch-up and stripe coating only.

Adequate masking and temporary covers shall be provided to prevent paint being supplied to areas where it is not required i.e. machined or polished surfaces, surfaces of stainless steels or certain non-ferrous alloys, name plates, manufacturer’s identification tags, instruments and instrument glasses, control valve stems, high strength friction grip bolt assemblies etc. If such items are inadvertently coated they shall be cleaned and restored to their original condition. Such masking or covers shall be removed after the painting activity is completed.




Care shall be taken that no zinc containing paints are applied on stainless steel items i.e. by over spraying. Adequate protection shall be provided.

Paint shall not be applied within a margin of 50 mm from an edge prepared for welding.

Sprayed metal coatings to comply with NACE No.#12/AWS C.2.23M/SSPC-CS 23.00: Specification for the Application of Thermal Spray Coatings (Metallizing) Aluminium, Zinc and Their Alloys and Composites for the Corrosion Protection of Steel.

8.1.2 Touch-up / Repair

Before application of any coat, all damage to previous coats shall be repaired.

Areas with inadequate coating thickness shall be thoroughly cleaned and if necessary, abraded and additional compatible coats shall be applied until they meet the required film thickness. These additional coats shall blend in with final coating on adjoining areas.

If condensation, rain, dust or other foreign material contaminates or settles on the surfaces of a paint coat which is not touch dry, the paint shall be removed, the surface re-cleaned and fresh paint applied in accordance with the specification. The removal shall be limited to a grit sweep of a surface.

Damaged areas where steel surfaces are not exposed shall be washed with a detergent and/or fresh water solution to remove all contamination, then rinsed using clean fresh water and be allowed to dry. The coating around the damaged area shall be chamfered, to ensure continuity of the patch coating. The full coating system shall then be reapplied.

Damaged areas down to bare steel shall be re-cleaned as originally specified for that item and the full coating system re-apllied. The cleaning shall be extended over the surrounding coating for not less than 25mm on all sides and the edges shall be chamfered.
