PAINT APPLICATION SPECIFICATION NO. 1 - Reli …

1 SSPC-PA 1 April 1, 2000 SSPC: The Society for Protective Coatings PAINT APPLICATION SPECIFICATION NO. 1 Shop, Field, and Maintenance Painting of Steel 1. Scope 1 .I This SPECIFICATION covers procedures for the PAINT - ing of steel surfaces. The scope of this SPECIFICATION is rather broad, covering both specific as well as general require- ments for the APPLICATION of PAINT . This SPECIFICATION does not provide detailed descriptions of surface preparation, pretreatments, or selection of primers and finish coats. This SPECIFICATION does provide detailed coverage of the proce- dures and methods for APPLICATION after the selection of the coating materials has been made.

2 2. Description This SPECIFICATION for shop, field, and maintenance painting is intended to be used for steel which, because of its exposure condition, will be subjected to corrosive attack, either from the weather or from the service environment, and where a high quality of cleaning and painting is essen- tial. It is not contemplated that the requirements of this SPECIFICATION are necessary for the cleaning and painting of steel which will not be subjected to corrosive attack. The following is a summary of the major sections of this specifi- cation.

Definitions SHOP, FIELD AND MAINTENANCE COATING: The APPLICATION of coatings to steel surfaces whether in the shop or in the field. PAINT : In the general sense, PAINT includes prim- ers, enamels, varnishes, emulsions, catalyzed coatings, bituminous coatings, and other organic coatings. Inorganic coatings which are also applied as liquid films are included in this definition.

8 This definition is compatible with most commonly used industry glossaries. SHOP COATING: The surface preparation and coating of steel surfaces inside a shop or plant before shipment to the site of erection. FIELD COATING: The on-site coating of new or previously coated steel structures before or after erection. MAINTENANCE COATING: The coating of steel structures in service that have been previously coated and require touch-up or recoating. OMMENDATIONS: These (or similar terms) are used to refer to an equipment supplier s or coating manufacturer s latest published or written instructions and recommenda- MANUFACTURER S INSTRUCTIONS AND REC- tions.

9 Verbal recommendations or instructions from an equipment or coating manufacturer are not acceptable unless backed up in writing by the manufacturer s technical staff. 5. Pre- APPLICATION Procedures See Section 11 for procedures unique to specific generic coatings. MATERIALS HANDLING AND USE All coating shall be delivered to the shop or jobsite in original, unopened containers with labels intact. Minor damage to containers is acceptable provided the container has not been punctured or the lid seal broken. Each container of coating shall be clearly marked or labelled to show coating identification, date of manufac- ture, batch number, and other information as needed to meet regulatory requirements.

10 Each type of coating shall be accompanied by the manufacturer s Material Safety Data Sheet (MSDS) and product data sheet containing information such as basic chemical composition, weather conditions acceptable for APPLICATION , and proper storing and mixing. All containers of coating shall remain unopened until required for use. No more containers of coating shall be opened than will be applied that day. The label informa- tion shall be legible and shall be checked at the time of use. Coating which has livered, gelled, or otherwise deteriorated during storage shall not be used; however, thixotropic materials which can be stirred to attain normal consistency may be used.
