Surface preparation shall be accomplished by certified blasters. Coating systems shall be applied by certified painters and test / inspection records maintained IAW Ref. 2.s, Section RAST Track PPI 2

3 (Quality Assurance Checklist). Checkpoints and final inspections shall be signed off by certified coating inspectors IN-PROCESS INSPECTIONS: Inspections are to be completed IAW Ref. 2.o, NSTM 631, Section 11 and Ref. 2.s, NSTM 634, Section The Responsible Government Representative certified coating inspector shall be given prior notice and shall perform an inspection of each coated area when the following checkpoints are reached: pre-surface preparation & cleaning, contamination containment and masking, surface preparation, paint storage area, mixing, prime coat, between successive coats of paint, topcoat of paint applied, nonskid applied, marking layout, color topping and area ready for final inspection. The Responsible Government Representative is also required to examine all data maintained by the paint foremen concerning environmental conditions, surface cleanliness, surface profile, and paint / nonskid thickness. Data shall be verified, depending on the checkpoint in question, including surface cleanliness, surface profile, wet film thickness, dry film thickness and workmanship. Environmental data, such as temperatures, relative humidity and dew point need only be verified if the inspector is doubtful of the recorded values. Deficiencies in personnel training, certification, record maintenance, equipment maintenance or any matter that is not IAW good painting practice shall be recorded. The coating inspector shall verify the successful completion of each checkpoint and sign and date the applicable spaces on Appendix RECORD KEEPING DURING SURFACE PREPARATION / PAINT AND NONSKID SYSTEM APPLICATION: A permanent record of environmental conditions, surface preparation, and nonskid system operations shall be maintained IAW Ref. 2.o, Section (Quality Assurance for Critical Coated Areas) and Ref. 2.s, Section , (Quality Assurance Checklist). Data shall be entered on Appendices 1A - 5 and 7. The record shall include dates and times of surface preparations, nonskid system operations, air temperatures, wet bulb, surface temperature, relative humidity and dew point. Enter on Appendix 1A the abrasive blast media manufacturer, type and size of abrasive used. Attach on Appendix 3 the TESTEX PRESS-O-FILM tapes used to measure surface profile. All appendices and data logger information shall be provided to the Contracting Regional Maintenance Center upon completion of the coating system installation. This information shall be retained for 3 years REVIEW OF RECORDS FOR FINAL COATING EVALUATION: A certified paint inspector authorized to represent NAVSEA shall review the Appendices of each area to ensure adequate quality control of the surface preparation, painting, and nonskid application process. Records shall include test and inspection data required by NSTM 631 Table (Ref. 2.o), and NSTM 634, Section 3.35, (Quality Assurance Checklist) (Ref. 2.s). Failure to produce such records, or records which indicate that surface preparation, painting and nonskid system application were not done IAW governing specifications/instructions, will be grounds for rejection RECORD DECK MARKINGS: Before removal of RAST track cover plates and track side plates, provide a record of existing periphery lines, exact locations, colors and dimensions of nonskid and deck coatings and markings on deck surfaces. Submit a copy to the Contracting Regional Maintenance Center and NAVSEA Technical Representative before starting pre-surface preparation. 4.8 ENVIRONMENTAL CONDITION READINGS: Environmental information on Appendices 1A-H shall be manually measured and recorded every 8 hours. Environmental readings shall be posted at the job site at all times, and an updated copy provided to the coating inspector and the Responsible Government Representative at each checkpoint for review. At each 8-hour recording period the readings shall be reviewed to determine if the environmental conditions are suitable for continued coating system installation. Additionally, a data logger shall be used to continuously monitor environmental conditions (air temperature, % relative humidity, and dew point) from 12 hours prior to, 48 hours after the application of a coat of paint IAW Ref. 2.c and NSTM 631, Sections 6, 7, and 8 and NSTM 634, Section 3.26 (Environmental Conditions) (Ref. 2.s). 4.9 TEMPERATURES TO BE MAINTAINED FOR NONSKID COATING SYSTEMS: Immediately prior to application of each layer of the coating system substrate surface temperature shall be taken. Readings shall be taken in five randomly chosen locations on the layer within the space and the highest and lowest surface temperatures measured recorded in Appendices 1B-1H. Additionally, readings shall be taken in five randomly chosen locations on the layer within the space and the highest and lowest surface temperatures measured recorded prior to resuming application of a layer of the coating system when there has been a temporary work interruption. Application of the next layer of the coating system shall not commence (or recommence after a temporary work interruption) until all recorded surface temperature readings are within the required range as specified in Ref. 2.c and NSTM 631, Section 6.3 and Ref. 2.s, Section (Environmental Conditions). If any reading is outside of the required range, the contractor must take additional action to control the temperature in the space and return the surface temperature readings to within the required range. Additional readings shall be RAST Track PPI 3

4 taken a minimum of hourly until the readings are returned to within the required range. If inconsistencies between the acceptable ambient and surface temperature ranges in Ref. 2.c, NSTM 631, Section 6.3, and Ref. 2.s, Section (Environmental Conditions) exist, the more stringent requirements shall be followed. If required ambient and surface temperatures are not provided or are unclear, contact Responsible Contracting Authority for resolution. 5. PRE-SURFACE PREPARATION: (REFER TO CORE PPI) 6.
