2.2 PAINT SYSTEM NOTES – NEW CONSTRUCTION:

CMU or pre-cast concrete with relatively large voids and localized, excessive porosity may require application of spackling to prevent visible “holes” after the complete system application.

The application of spackling (e.g. light weight spackling) shall be performed prior to the 1st coat of finish. For CMU, the intent is to match the general appearance of the surrounding CMUs not to level out all inherent concavities.

DFT measurements shall not be the only method used to verify conformance. The final appearance is the primary determination (e.g. sealed voids, uniform appearance, minimal roller texture, fully opaque etc.).

Mortar shall be cured according to the mortar manufacturer’s recommendations or other approved test method (e.g. hardness, pH etc.). At a minimum, the mortar shall be hard and not able to be gouged with moderate pressure (i.e. not friable).

Repairs to walls after application of paint/coatings shall include, at a minimum, the same number of coats, or more coats in order to reach a uniform appearance.

Concrete and masonry surfaces shall be rubbed and pointed prior to paint/ coating or sealer application. If appropriate conditions do not exist notify the General Contractor of the defect for correction.

Mortar repairs shall be performed using polymer-modified mortar and verified to be hard prior to paint/coating application.

If paint application is to be performed prior to 14 calendar days after Portland cement plaster (stucco) application, document testing of all elevations for sufficient cure. Testing shall be performed by the paint/coating manufacturer or 3rd party and include pH and general hardness (texture and finish coat).

If trowel marks or other minor defects on gypsum plaster necessitate sanding the surface, follow by thoroughly washing and wiping with clean potable water or as per manufacturer’s recommendation.

Pre-Cast concrete components that are dense and smooth (e.g. window sills) shall be etched with ASTM D 4260 Acid Etching Concrete. Acid etch with muriatic acid (20 Baume) to produce a porous substrate and a finish similar to 80 grit sandpaper. Thoroughly rinse after effervescing action and do not allow drying prior to rinse. This operation shall be performed prior to installation and verified (documented) using water penetration testing.

Repair damage to the HDG coating per ASTM A 780 Repair of Damaged and Uncoated Areas of Hot-Dip Galvanized Coatings (use of aerosol spray “cold galvanizing” is not permitted).

The total DFT range shall be increased by 1.0 mils to account for the DFT of the HDG. Field touch-up shall be performed prior to installation into the wall and after installation, inspect to determine if additional touch-up is necessary.

15 of 23 Revised: 6/3/25

2.2 PAINT SYSTEM NOTES – NEW CONSTRUCTION:

Field touch-up is required where the shop-applied epoxy primer has been mechanical damaged.

Proper mixing of “partial kits” is acceptable for this application. The surface preparation shall be as follows: Sand the surface to remove loose rust and/or to smooth the surface followed by solvent cleaning. If the mechanical damage exposed the base metal (i.e. visible rust), two spot coats shall be applied and the repaired surface sanded smooth prior to the finish coat application putty body filler repairs shall be spot painted with SBp-08 prior to finish coat application.

Steel profile shall be measured in accordance with ASTM D 4417 Field Measurement of Surface Profile of Blast Cleaned Steel, Method C. A minimum of three (3) locations shall be measured.

Replica tape shall be affixed to all QC reports. Abrasive blasting and primer application shall be performed only when the steel surface temperature is at least 5-degrees F above the dew point temperature; verified through instrumental testing in the work area.

DFT shall be measured in accordance with SSPC-PA 2 Measurement of Dry Coating Thickness with Magnetic Gages and documented.

A mock-up application shall be performed and evaluated by the PA/E prior to beginning the full application. The manufacturer or 3rd party shall perform “RILEM Tube” testing and at least two locations shall be measured (one location over a mortar joint). The results of the RILEM Tube testing shall be reported based on the amount of water-uptake and respective number of minutes (e.g. 1.0 mL in 15 minutes). The results of the testing will determine the pass-fail criteria for the entire project. Porous substrates may require more than one application to meet the acceptable criteria established by the water repellent supplier (to receive the warranty).

After the prime coat has been applied on wood surfaces, nail holes shall be filled with putty.

Putty shall be brought flush with the surface of woodwork and sanded.

Knots sap and pitch streaks in lumber shall be sealed with SBP-12 before the prime coat is applied.

DFT measurements will not be used to verify conformance. The final appearance is the primary determination (e.g. fully opaque, uniform color and sheen etc.).

Cure testing shall be performed by the paint/coating manufacturer or 3rd party and include pH and general hardness.

Apply flood coat to entire surface and maintain uniform wet-look for 20 minutes. If suction/penetration is observed, re-apply.

Etch in accordance with ASTM D 4260 Acid Etching Concrete; utilize muriatic acid (20 Baume) to produce a porous substrate. Thoroughly rinse after effervescing action and do not allow drying prior to rinse. Test surfaces for pH and if found to be acidic, treat with a solution of sodium bicarbonate and water.

2.5 PAINT SYSTEM NOTES – PREVIOUSLY PAINTED SURFACES

A. Mildew and algae shall be treated prior to pressure cleaning by (1) a solution of one quart “household bleach” (3 – 6-percent sodium hypochlorite) to one-gallon potable water applied using a low-pressure sprayer, or (2) pressure cleaner with chemical injector using “pool chlorine” (10 – 12-percent sodium hypochlorite). Do not allow solution to dry on surface prior to pressure cleaning.

B. If pressure cleaning is used to completely remove/strip deteriorated paint, the surfaces shall be permitted to dry for a minimum of 72 hours prior to primer application.

C. Cracks in exterior stucco shall be patched using elastomeric patching compound using the

“texture” that matches the surfaces being patched (e.g. sand textured or smooth textured).

1) Hairline cracks (i.e. less than 1/64-inch at its widest point) shall be patched using “brush grade” patch worked into the crack and flush with the surface.

2) Cracks between 1/64-inch and 1/8-inch shall be raked-out and wire brushed to remove loose materials. Patched with “knife grade” patch with build-up over the crack and sufficiently textured to match surrounding stucco texture. Two applications may be required.

3) Cracks larger than 1/8-inch shall be saw-cut to a uniform depth (e.g. 1/4 – 1/2-inch, wire brushed and vacuumed, install bond-breaking tape or closed-cell backer rod, install one-part polyurethane sealant (tooled flush). After 4-days of cure time, use “knife-grade” elastomeric patching compound to blend with surrounding stucco.

D. Tap surfaces to determine the soundness of the stucco. Locations to focus are as follows:

(1) where cracks are observed, (2) base of wall, (3) around windows and doors.

E. Remove loose stucco and mortar; patch using pre-mixed cementations patch (i.e. Euclid

Eucopatch). For stucco, the mix shall be enhanced using a 100-percent acrylic additive (e.g.

Euclid Flex-Con).

F. Scarify all surfaces to be coated to achieve a uniform anchor pattern for the subsequent coatings. Solvent wipe (e.g. denatured alcohol) to remove all particulate created as a result of abrading.

G. Steel surfaces showing signs of rust (bleed-through or blistering) shall be prepared in accordance with SSPC-SP 3, Power Tool Cleaning.

H. All loose, peeling paint, raised paint edges shall be scraped back until tightly bonded. Paint edges shall be sufficiently bonded as not to be lifted by the blade of a dull putty knife.

I. DFT measurements shall not be used to verify conformance. The final appearance is the primary determination (e.g. sealed voids, uniform appearance, minimal roller texture, fully opaque etc.).

J. DFT shall be measured in accordance with SSPC-PA 2 Measurement of Dry Coating

Thickness with Magnetic Gages and documented.

K. A mock-up application shall be performed and evaluated by the PA/E prior to beginning the full application. The manufacturer or 3rd party shall perform “Rilem Tube” testing and at least two locations shall be measured (one location over a mortar joint). The results of the

Rilem Tube testing shall be reported based on the amount of water-uptake and respective

23 of 23 Revised: 6/3/25 number of minutes (e.g. 1.0 mL in 15 minutes). The results of the testing will determine the pass-fail criteria for the entire project.

L. After the prime coat has been applied on wood surfaces, nail holes shall be filled with putty.

Putty shall be brought flush with the surface of woodwork and sanded.

M. DFT measurements will not be used to verify conformance. The final appearance is the primary determination (e.g. fully opaque, uniform color and sheen etc.).

N. Cure testing shall be performed by the paint/coating manufacturer or 3rd party and include pH and general hardness.

O. Apply flood coat to entire surface and maintain uniform wet-look for 20 minutes. If suction/penetration is observed, re-apply.

P. Cracks, damage and holes in interior stucco, plaster, and drywall shall be patched using proper patching compounds per manufactures recommendations using the “texture” that matches the surfaces being patched (e.g. sand textured or smooth textured).

Q. Hairline cracks (i.e. less than 1/64-inch at its widest point) shall be patched using “brush grade” patch worked into the crack and flush with the surface.

R. Cracks between 1/64-inch and 1/8-inch shall be raked-out and wire brushed to remove loose materials. Patched with “knife grade” patch with build-up over the crack and sufficiently textured to match surrounding sub-straight texture. Two applications may be required.

S. Cracks larger than 1/8-inch shall be saw-cut to a uniform depth (e.g. 1/4 – 1/2-inch, wire brushed and vacuumed, install bond-breaking tape or closed-cell backer rod, install one-part polyurethane sealant (tooled flush). After 4-days of cure time, use “knife-grade” patching compounds to blend with surrounding surface to match texture.

T. Patch gouges and damage using stainable putty followed by sanding smooth and staining to match color.

U. Etch in accordance with ASTM D 4260 Acid Etching Concrete; utilize muriatic acid (20

Baume) to produce a porous substrate. Thoroughly rinse after effervescing action and do not allow drying prior to rinse. Test surfaces for pH and if found to be acidic, treat with a solution of sodium bicarbonate and water.
