2.02 MATERIALS
A. Coatings: Ready mixed, except field catalyzed coatings. Process pigments to a soft paste
consistency, capable of being readily and uniformly dispersed to a homogeneous coating. Good
flow and brushing properties; capable of drying or curing free of streaks or sags.
B. Accessory Materials: Linseed oil, shellac, turpentine, paint thinners and other materials not
specifically indicated but required to achieve the finishes specified. Of commercial quality.
C. Cement - Base Patching: Thorite by Thoro System Products of Miami, Florida.
D. Colors: When not specified, as selected by the Owner.
2.03 EQUIPMENT
A. Use effective oil/water separators on all compressed air lines serving spray painting and
sandblasting operations to remove oil or moisture from the air before it is used. Place separators
as far as practicable from the compressor.
B. All equipment for application of the paint and the completion of the Work must be in first-class
condition and comply with recommendations of the paint manufacturer.
PART 3 EXECUTION
3.01 INSPECTION
A. Applicator must examine areas and conditions under which painting Work is to be completed and
notify Engineer in writing of conditions detrimental to proper and timely completion of Work.
B. Inspect the substrate and report any unsatisfactory conditions. Contractor is not responsible for
latent defects in the substrate which can not be detected during a reasonable visual inspection.
Starting the Work indicates acceptance of the substrate as constructed.
C. All surfaces to be painted are subject to review by the Engineer before application of the prime
coat and each succeeding coat. Any defects or deficiencies are to be corrected by the Contractor
before application of any subsequent coat.
D. When any appreciable time has elapsed between coats, previously coated areas are to be reviewed
by the Engineer. Where surfaces are damaged or contaminated, they are to be cleaned and
recoated. Adhere to recoating times of manufacturer's printed instructions.
3.02 SURFACE PREPARATION
A. General: Clean surfaces as specified and in accordance with the manufacturer's recommendation
for the coating being used. If surfaces are subject to contamination other than mill scale or
normal atmospheric rusting, the surfaces are to be pressure washed, and acid or caustic pH
residues neutralized, in addition to the specified surface preparation.
B. Concrete and Masonry: Remove all oil, grease, dirt, laitance and other foreign materials. Blast
remove all existing coatings using equipment rated at 3500 psi. Acid etch with a solution of
muriatic acid and then rinse with clean water. Verify required acid-alkali balance is achieved.
Surface must be dry and free of dust prior to painting. New concrete and masonry must be cured
a minimum of 28 days before treating and coating.
Repair damaged concrete using a cement base patching system. Use in strict accordance with the
manufacturer's recommendations.
C. Plaster: Remove dirt, loose mortar, scale, chalk, salt or alkali powder, and other foreign matter.
Remove oil and grease with a solution of tri-sodium phosphate; rinse well and allow to dry.
