1 Scope

1.1 This standard covers the minimum mandatory requirements for surface
preparation, coatings application, and coatings materials selection for the
concrete surfaces in industrial facilities both onshore and offshore.

Exception:

Coating of above ground/atmospheric concrete structures is not required, unless
otherwise specified in other standards and project documents.

1.2 This standard shall not cover water-proofing materials designed to slow or
prevent chloride ion attack or carbonation, or to address the decorative finishes
utilized for concrete buildings. It does not cover the concrete repair materials
prior to coating such as sealers and synthetic membranes sheets.

1.3 The objectives of concrete coatings are as follows:

a) Protection from chemicals.

b) Protection from wear, abrasion and impact.

c) Mitigation of steel reinforcement corrosion.

d) Mitigation of fouling.

2 Conflicts and Deviations

2.1 Any conflicts between this standard and other applicable Saudi Aramco
Engineering Standards (SAESs), related Materials System Specifications
(SAMSSs), Codes, Forms, Standard Drawings (SASDs), and industry standards,
shall be resolved in writing through the Manager, Consulting Services
Department (CSD) of Saudi Aramco, Dhahran.

2.2 Direct all requests to deviate from this standard in writing to the Saudi Aramco
Representative, who shall follow internal company procedure SAEP-302 and
forward such requests to the Manager, Consulting Services Department of Saudi
Aramco, Dhahran.

3 References

The selection of material and equipment, and the design, construction, maintenance, and
repair of equipment and facilities covered by this Standard shall comply with the latest
edition of the references listed below unless otherwise noted.

5.4.1.1 Electrically driven power tools shall be properly grounded to
prevent shock.

5.4.1.2 Power equipment shall be operated at the speeds recommended
by the manufacturer and shall have proper safety guards.

5.4.1.3 Hearing protection shall always be worn whenever chipping
guns or pneumatic hammers are in use.

5.4.1.4 Vessels such as air receivers that are used as a surge tank
between the compressor and the blasting pot shall be
manufactured and stamped in accordance with ASME SEC
VIII D1, Unfired Pressure Vessels. They shall be hydro tested
at a pressure of 1.3 to 1.5 times the maximum operating
pressure stamped on the vessel, dependant on the year of
construction, at ambient temperature using clean water. These
vessels shall be revalidated by hydro testing at least annually
and the test certificates shall be submitted to the Saudi Aramco
Inspector for verification.

5.4.1.5 All pressure relief valves, gauges, and devices shall be tested
annually and tagged with the expiration date. The test
certificates shall be submitted to the Saudi Aramco Inspector
for verification.

5.4.1.6 All blasting and coating equipment and associated attachments
shall be adequately earthed to avoid electrostatic discharges.

5.4.2 Abrasive Blasting Equipment

5.4.2.1 All Blasting machines shall be equipped with a "deadman"
shut-off controls.

5.4.2.2 The blast nozzle shall be electrically connected to an external
ground in order to prevent static electrical discharges or shocks
to operating personnel. Grounding wire shall be AWG-4 or
larger.

5.4.2.3 The blasting hose shall be the static dissipating type with
external couplings.

5.4.2.4 Respirable air-fed abrasive blasting hoods and OSHA-
approved in-line respirable air filters shall be utilized at all
times by abrasive blasting personnel.

5.4.2.5 Compressor hoses, air lines, and blast hoses shall be safety
locked at each coupling using proper safety pins.

5.4.2.6 Hearing protection shall be worn in confined spaces where
abrasive blasting is in progress.

5.4.3 Solvent Cleaning

Benzene, gasoline, carbon tetrachloride, and chlorinated hydrocarbons
with low threshold limit values (less than 20) shall not be used

5.4.4 Paint Preparation and Equipment Cleaning

5.4.4.1 Coatings shall be mixed outside or in an adequately ventilated
area. Use eye protection (goggles) and protective gloves.

5.4.4.2 Electrically driven power mixers shall be grounded.

5.4.4.3 Avoid splash or spillage during mixing. Clean spilled paints
immediately using proper cleaning solvent.

5.4.5 Airless Spray Paint Application

5.4.5.1 Airless spray guns shall never be pointed at anyone or at any
part of the body.

5.4.5.2 The tip guard shall always be in place on the airless gun while
spraying.

5.4.5.3 Leather gloves shall be worn by the operator whenever the
airless spray gun is in use.

5.4.5.4 The trigger safety catch shall be engaged whenever the airless
gun is left unattended.

5.4.5.5 Hoses, pumps, and accessories shall never be operated at
pressures exceeding their rated pressure. In no case shall the
working pressure in the paint line exceed 34.5 MPa (5000 psi).
Safety pressure relief valves shall be used on discharge side of
the pressure pump(s).

5.4.5.6 The pump shall be shut down and the fluid pressure in the
system relieved before servicing or cleaning any components,
including clogged spray tips.

5.4.5.7 Hoses shall be grounded, anti-static type.

repair procedures accepted by Saudi Aramco Inspector.

9.5.2 All damages from inspections (i.e., adhesion testing, wet film thickness
tests etc.), shall be repaired.

9.6 List of inspection and testing requirements

The following inspection steps shall be performed by the assigned quality
control inspector from the contractor side in the presence of Saudi Aramco
inspector. Saudi Aramco Inspector reserves the right to perform any test at any
time to verify and assure the quality of the work being implemented:

9.6.1 Survey the condition of Concrete as per ACI 201.1R or equivalent.

9.6.2 Verify the degree of cured concrete.

9.6.3 Verify the strength of concrete as per ACI 228.

ASTM D4541.

9.6.5 Detection Alkali-Silica Reaction in Concrete as per ASTM C295.

9.6.6 Verify removal of protrusion, filling surface indentations, and treat other
surface irregularities.

9.6.7 Check the ambient condition and inspecting the surface preparation
equipment.

9.6.8 Test for surface contamination from grease, oil and form release agents
before and after surface cleaning.

9.6.9 Test for retained moisture in concrete as per plastic sheet method ASTM
D4263 or by moisture meter or by calcium chloride dome test in ASTM
F1869.

9.6.10 Test for Concrete Surface profile (CSP) as per guide in ICRI 03732.

9.6.11 Inspect coating mixing, thinning, pot lives, and top-coatings interval
