Small amounts of grease or oil deposits =ay be removed by blast operations. Final blasting shall not begin unless the temperature of the surface to be blasted is 5'F or mo're above the dew point. The surface shall be cleaned by blasting to SSPC-SP-10. "Near White Blast" cleaning. Blasting operations shall be performed with blast abrasive which will achieve a minimum profile of 1 mil. 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. Sufficient time shall be provided to allow suspended particles to settle before beginning primer application. If rust forms af ter surface preparation, the rusted area shall be reeleaned before primer application. Generally a blast cleaned surface shall not be exposed for more than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />

, 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:

a. Blasting using no border tape - Overblast the steel to near white metal approximately 12" - 18" beyond the point which will receive primer. Hold back approximately 12" - 18" from edge of blasted area when applying primer. ,
b. Blasting using border tape - Clean the steel to near white

. metal approximately 3" - 6" beyond the point which will receive primer. Place border tape approximately 1" in from the edge of cleaned area and prime. When applying seal or finish coat on either of the above methods hold back approximately 12" - 18" from edge of primer.

3.1.2 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 and SSPC-SP-3. If it is determined that surface defects are sever enough 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.

Weld seams, edges and other sharp geometrical discontinuities may receive an initial coat of I-2 mils finish coating thinned by using two quarts Phenoline Thinner per each. gallon kit of Phepoline 305. To aid in continuity at edges, edges eay be " striped" with Phenoline unthinned instead of the 30% mixture as stated above. In either

" striping" or 1:.itial coating of edges, welds, etc., time should be allotted for the coating to harden sufficiently to maintain a " sealing" effect prior to continuing coating opera-tions. The initial coating of edges, striping, etc., as stated above, shall be considered part of the total initial finish coating operation. The material shall be allowed to become tack free before any other construction operations proceed which could create contamination problems by dust or other foreign matter. A continuity check may be performed in accordance with NACE I-6F-3 Condition "C". No gross dis-continuities are acceptable such as holidays, voids, skips, bubbles, and misses. Any runs or sags having a detrimental effect on the coating system shall be removed and repaired.

The following application parameters shall govern:

a. The permissible range of surface and ambient temperature for application shall be 50* - 120' F.

Temperature may rise above 120' F after caterial has become " tack free". Phenoline 305 may be thinned up to 2 quarts of Phenoline Thinner per gallon mix.

The ratio of thinner to Phenoline will be that which gives the best workable mix, i.e., usually advantageous L to use more thinner at lower temperatures.

I

b. Minimum and-maximum values of relative humidity shall be 0% and 85 respectively.

( c. As a guide for spray application, coating material

! shall be applied using a 50% overlap with each pass while holding the gun 8 - 10 inches from the surface, l-

d. The ambient temperature and relative humidity shall be measured to determine the dew point temperature.
