GENERAL
4.1.1
Before any surface preparation is commenced, the surface shall be completely dry and free from burrs, weld spatter, flux, loose scale, dirt, oil, grease and any other foreign matter.
4.1.2
The preferred method of pre-cleaning is with steam (however, should be avoided in the open field). If steam cleaning is not possible, solvent cleaning shall be executed using a suitable solvent in accordance with SSPC-SP1. If so required detergent may be used to remove oil or grease.
4.1.3
After steam cleaning in combination with detergents or solvents the surface shall be flushed/rinsed with fresh water.
4.1.4
Surface preparation shall be in accordance with the minimum preparation grade to ISO 8501-1, NACE or SSPC for each paint system specified in this specification and/or the paint manufacturer’s recommendation if they are more stringent. Refer to paragraph 3.3 for comparison of ISO grades, SSPC grades and NACE grades.
4.1.5
After the specified standard has been achieved, all dust, debris and abrasive residues shall be removed from the blasted, hand or power tool cleaned surface and the surface shall be painted before contamination or flash rusting occur.
4.1.6
Rough welds, sharp edges, etc., shall be ground smooth prior to blasting.
4.1.7
Machinery shall not be grit blasted. The use of power tools on machinery is to be limited and if used, the chance of ingress of particles in sensitive areas, such as labyrinths of mechanical seals, etc., shall be avoided.
4.1.8
Blast cleaning shall be executed using one (1) of the following abrasives:
4.1.9
Chopped steel wire. Steel and malleable iron grit. Chilled iron grit or shot. Non-metallic abrasive for CS surfaces: copper slag, garnet, etc. Non-metallic abrasive for SS surfaces: aluminium oxide - particle size 0.8-1.2 mm, or glass beads.
Sand or other potentially silicon-containing materials shall not be used, because of safety regulations. Compressed air for blast cleaning shall be free from water and oil.
4.1.10 Blast-cleaned surfaces shall provide a good anchor pattern for primers, but shall not show excessive roughness. The anchor pattern shall be:
Rz: 40-70 for inorganic zinc primer. Rz: 35-50 for other primers.
4.1.11 Blast cleaning shall not be executed when: S-000-53A0-001
Surface temperature is less than 3°C above dew point. RH is above 90%. There is any possibility that the surface is wetted before the first coat is applied. When the available light is less than 550 lux. Rev. No. 5

4.1.12 Stainless steel, hot-dip galvanized steel and nonferrous metals shall be sweep blasted (light blast cleaning) with a suitable abrasive. 4.1.13 For stainless steel and nonferrous metals, steel wire brushes are not allowed. Nonmetallic wire brushes and/or scrapers shall be used. 4.1.14 Surface preparation in the prefabrication or site paint shop shall be by blast cleaning. Surface preparation at the jobsite shall be by hand or power tool cleaning only, unless dictated otherwise by the paint manufacturer. Blast cleaning at the jobsite is only allowed after approval of Client. Note that when hand/power tool cleaning is specified, both methods are acceptable as long as the required specification will be reached. 5.0
PAINT MATERIAL PREPARATION
5.1
STORAGE The painting materials shall be stored strictly in accordance with the instructions of the paint manufacturer. This means, in general, that painting materials should be stored in a dry, cool, well ventilated and frost-free area.
5.2
PACKING Paint containers shall be factory sealed and clearly marked with paint manufacturer's name, batch number, date of fabrication, shelf life and a clear indication of the type and color of product. The containers shall remain closed until the contents are required for use. The oldest material of each kind shall be used first.
5.3
MIXING Paint shall be thoroughly mixed prior to application. Mixing shall be done in a well-ventilated, clean and dust-free area. Paints shall be mixed by rotating power mixers or rolling rigs, until a uniform consistency is achieved. Multiple pack paint materials shall be mixed in accordance and under the conditions as specified by the paint manufacturer. Containers with hardener shall be completely emptied into the container of the base material. No more material shall be prepared at the same time than can be used within the time designated by the paint manufacturer as "pot life" (life after opening of container).
5.4
THINNERS AND SOLVENTS Only additives, thinners, solvents, etc., as recommended by the paint manufacturer, shall be used. A possible extension of the "pot life" by the additions of thinners is prohibited.
