4.0 Execution

4.1 Surface Preparation

A. Concrete Surfaces

(1) Prior to painting, surfaces to be free of all latent matter, burrs, and fins, using one or more of the following methods.

a) Wash concrete surfaces with 10 percent solution of muriatic acid, then wash clean and free of scale, mortar, dust, moisture, and other foreign matter.

b) Abrasive blasting may be used only if machinery or other equipment in vicinity of work is adequately protected. Also, avoid settling of dust or grit on freshly painted surfaces.

c) Remove oil and grease with detergent and thoroughly rinse with fresh water.

(2) If curing compound is used, it must be removed prior to coating.

B. Ferrous Metal Surfaces

(1) Clean surfaces by abrasive blasting in shop as shown in Table-1 of this Section and leave clean, dry, and ready to receive prime coat. Provide moisture separators to effectively remove all oil and free moisture from air supply. Remove all dust and sand from ferrous metal surfaces by brushing or blowing with clean, dry air, and remove all grit around and between joints of connecting members.

(2) Perform field abrasive blasting only if required to correct unsatisfactorily cleaned and shop-primed ferrous metal and when approved by Engineer.

(3) Removal of Oil and Grease: Remove oil and grease with a solvent approved by coating manufacturer or by steam combined with detergent. Use of gasoline, kerosene, naphtha, or carbon tetrachloride not permitted.

(4) Brushing, Scraping, Grinding, and Chipping: In field work, if abrasive blasting is not possible, scrapers, wire brushes, and other suitable grinding or chipping tools may be used for removal of existing paint coatings prior to repainting, or for cleaning, before applying second coats.

(5) Surfaces which have been cleaned but which have started to show signs of rust or dirt are to be cleaned again prior to coating at no additional expense to Owner. Surface to be coated on same day as cleaned.

4.2 Application of Protective Coatings

A. General

Use one convenient location for storing and mixing of materials and keep fire extinguisher available in this area as long as location is used for such purpose. Protect floors and all other areas where work is done, with suitable drop cloths, and remove oily rags and waste from building at close of each day’s work. On completion of operations, remove all spots, oil, and stain from all surfaces and leave entire project in clean condition as far as this work is concerned. Remove from premises all containers and debris resulting from this work.

B. Thinners and Solvents

Section 00100-025 Page 3 Revised 7/26/2023

Use only those thinners and solvents specified in paint formulas of paint being used and mix in proportions recommended by paint manufacturer.

C. Coverage

As recommended by paint manufacturer and sufficient to obtain minimum mil thickness specified. Do not exceed maximum thickness specified by manufacturer, if applicable.

Verify total thickness and document the coating thickness after final coat is applied.

D. Drying Time

Between successive coats, allow drying time as specified by paint manufacturer.

E. Brush Application

(1) Brushes: Use first-quality hog hair or suitable synthetic bristle brushes. Use of horse hair bristle brushes not permitted. Keep brushes clean and free from accumulation of dried paint or dirt, and when brushes for oil or varnish base paints are not in use, keep them suspended in raw linseed oil bath. Clean brushes with turpentine or mineral spirits before reuse.

(2) Application: Apply in uniform thickness consistent with specified coverage and with sufficient cross-brushing to ensure filling of surface irregularities. Exercise particular care in painting around bolt heads and nuts and in corners and other restricted spaces.

F. Spray Application

(1) Apply with adjustable air gun equipped with suitable water trap to remove moisture from compressed air and with paint pot having hand agitator. Apply with width of spray not less than 12 inches nor more than 18 inches and with suitable pressure for particular type of paint being used. Make frequent checks to ensure correct spreading rate and coating, and apply without sags, runs, or “orange peel” effect. Correct all such imperfections. Take special care to cover edges, corners, and bolt heads, without bridging over of paint film.

G. Ferrous Metal Surfaces

(1) Shop-prime ferrous metal surfaces prior to delivery to jobsite

(2) After delivery and prior to installation, keep all coated metal surfaces clean and free from corrosion. Clean and touch up or repaint damaged areas with additional primer.

(3) After erection or installation of metal work, clean and touch up all rust spots, all places where primer has been rubbed or scraped off, and all bolts and nuts. After previously applied paint has hardened, and when surfaces to receive succeeding coats of paint have been cleaned and dried, apply finish paint in accordance with Table-1. Allow 5 days or more as recommended by coating manufacturer for hardening of final coat for submerged surfaces.

(4) Factory-Finished Equipment: After installation of factory-finished machinery and electrical equipment, check base coats carefully and touch up all damaged surface areas. Do not paint nameplates, serial number bases, chrome, or bronze trim. Clean off any excess paint that impairs convenient removal of covers on gauges, instrumentation, or other equipment fitted with doors or covers.

Section 00100-025 Page 4 Revised 7/26/2023

(5) Factory-Primed Equipment: Delay final field coating to manufacturer’s primed equipment until equipment ahas been installed and is in proper working order in accordance with the applicable Item.

H. Provide protection for adjacent property or properties from windblown blasting abrasives, paint, and other debris. Schedule field operations to avoid settling of dust or grit on freshly painted surfaces and adequately protect machinery or other equipment in vicinity of abrasive blasting work.

I. Provide Engineer with necessary equipment for access to observe all areas before first coat and after each coat.

J. Provide Engineer with proper safety equipment for observation.

K. Provide adequate ventilation for proper curing.

4.3 Special Requirements

A. Cast iron or ductile iron piping and valves for interior and exterior installation with a factory-applied bitumastic or asphaltic varnish coating to be abrasive blast cleaned in accordance with Table-1 and coated with compatible material prior to finish system. If finish system not applied within 24 hours, surfaces to be retreated.
