If needed, the surface to be primed shall then be cleaned of any heavy oil or grease deposits in accordance with SSPC-SP-1-63 " Solvent Cleaning". Small amounts of grease or oil deposits may be removed by blast operations. The, surface shall then be cleaned by blast, hand or power tool operations to achieve an equivalent of SSPC-SP10-63, "near white" blast cleaning. Although 1-3 mil. surface profile is preferred, a minimum of 1 mil. profile is required. After the above surface preparation, the surface to be primed shall be air blasted and/or solvent wiped to remove dust, sand or foreign contaminants from the surface. Air blasting shall not be performed where air-borne contaminants could adhere to tacky paint. Suffi-cient time shall be provided to allow suspended particles to settle before beginning primer application. If rust forms after st.rface preparation, the rusted area shall be re-cleaneo before primer application. Under no case shall a blast, hand, or power tool cleaned surface be exposed for more than 24 hours prior to priming without additional cleaning of the surface. When applying coatings that will be joined together by a later coating operation, the interface shall be constructed as follows:

! 4.1.2 Removal of weld spatter and other minor surface imperfections (not to ! exceed .031" for containment liners) - If needed, weld spatter omitted by ! others will be removed by Painting Personnel in accordance with SSPC-SP-2 l and SSPC-SP-3. If it is determined that surface defects are severe enough j to require later repair, the area to be repaired will be blocked out and spot painted at a later date. All protrusions and peaks shall be ground to a rounded contour.
4.1.3 If coating removal is required from an area or item which has previously ( been coated in accordance with this procedure, shadows or tight residue j of primer which may remain in the profile of the previously prepared sub-strate is acceptable. However, areas with residues of Carboline 191 I Primer shall be recoated with Carboline 191 Primer. Areas with residues of inorganic zine may be coated with either inorganic zine or Carboline 191 Primer. It is not required that such areas meet the criteria of SSPC-SP13 or SSPC-SP6. 4.2 SURFACE PREPARATION FOR FINISH C0AT h 4.2.1 Surface preparation for the finish coat shall consist of the removal, if g needed, of any oil or grease. This shall be accomplished by the use of a manufacturer recommended cleanser or cleansing method on areas that have j been seal-coated. On areas where the Carbo Zine 11 primer is exposed, oil i and grease will be temoved by sand blasting, hand, or power tool grinding, i and needle scaling and then by solvent wiping the area prtet to replaceing I the primer. Power tool grinding and needle scaling should yield surface cleanliness equal to that of SSPC-SP-10 "near white" blast cleaning. Power , tooled areas should be kept to a minimum however no size limitation is imposed providing acceptable surface cleanliness is achieved. < 4.2.2 The ambient temperature and relative humidity shall be measured to determine the dew point temperature. Phenoline 305 finish shall not be applied unless the substrate temperature is 5'T or more abovT*the dew point. , i a L_____ _ ______CCP _30A R_ev._2 DCNf_6_ _ _ _ _ _ _ _ _m2 __ _ _-_ _ 11/16/83 Sheet 2 of 4
