SURFACE PREPARATION HOW IT PLAYS A KEY ROLE IN THE SPECIFICATION PROCESS?

SURFACE PREPARATION & ITS IMPORTANCE
The means and methods of creating a surface that is in a condition to accept the type of coating specified. Why is it important to include proper surface preparation when specifying? Coating performance is dependent on adequate adhesion Coating systems can fail prematurely due to inadequate surface preparation Dollars lost due to improper surface preparation Each year millions of dollars are wasted on good coating systems that will fail prematurely due to inadequate surface preparation or improper application.

THREE MAIN FACTORS THAT AFFECT COATING PERFORMANCE
Surface Preparation Coating Selection Application Properly written painting specifications incorporate surface preparation and application procedures as an integral part of the coating system in recognition of this fact.

PROBLEMS ASSOCIATED WITH IMPROPER SURFACE PREPARATION
Peeling Coating breakdown at welds Blistering Undercutting Pinpoint Rusting Cratering Rusting Edge Rusting

SURFACE PREPARATION: DOES IT HAVE VALUE?
Cost Breakdown of a Typical Coating Operation: Application Labor 30 – 60% Surface Preparation 15 – 40% Coating Materials 15 – 20% Clean-Up Labor 5 – 10% Tools and Equipment 2 – 5% The major cost of a coating system is not the coating material itself, but the cost of labor for surface preparation and application of the coating system.

SURFACE PREPARATION STANDARDS
What types of standards are available as reference for preparing a surface for coating application? Society of Protective Coatings (SSPC)—formerly the Structural Steel Painting Council NACE International (NACE)—formerly the National Association of Corrosion Engineers International Standards also exist i.e., ISO

SURFACE PREPARATION STANDARDS
Overview of Common SSPC Standards SSPC-SP 1: Solvent Cleaning SSPC-SP 2: Hand Tool Cleaning SSPC-SP 3: Power Tool Cleaning SSPC-SP 5: White Metal Blast SSPC-SP 6: Commercial Blast SSPC-SP 7: Brush-Off Blast Cleaning SSPC-SP 10: Near-White Metal Blast SSPC-SP 11: Power Tool Cleaning to Bare Metal

CAN YOU BLAST CLEAN? Abrasive blast methods generally not feasible
Thin-gage steel will warp Surrounding area not conducive Other means of scarification Power tool options Hand sanding Water Jetting Standards SSPC WJ-1 through WJ-4 Range of cleanliness definitions Various pressure requirements Choosing the most effective method of surface prep is vital to the durability and longevity of a coating system. Specific preparation capabilities will vary from project to project, although all existing surfaces must be clean, dry, and contaminate free prior to overcoating. Oftentimes, dry abrasive blasting is not feasible on roof overcoat projects. The method is too aggressive for the thin gage substrates, and the surrounding areas are not conducive to the dust. Power tool and hand sanding can be very effective, but labor intense. We have seen growth in waterjetting standards. The recently release SSPC/NACE joint standards for water jetting are broken into 4 levels of cleanliness. In many cases, they can provide the criteria for producing a sound over-coatable surface.

SSPC-SP11 Power Tool Cleaning to Bare Metal
Use of power tools to produce or retain surface profile. Suitable when abrasive blasting is not feasible. Free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, foreign matter. Min 1 mil profile required

CASE STUDY #1 Corporate Headquarters Seattle, WA
“The project’s original specification called for a urethane topcoat, but because of the complexity of the environment with all of the plants, trees and waterfall inside, the specification was changed to a fluoropolymer coating system. Steel fabricator spray-applied a prime coat of a zinc-rich aromatic urethane, once the steel was shipped to the site and assembled a single-component aromatic urethane coating containing less than 100 g/L of VOC was used. Applicators completed the coating system with an intermediate coat of a water-based epoxy with exceptional durability and corrosion resistance, and the finish coat of a low-VOC, fluoropolymer coating with outstanding color and gloss retention. Coatings were roller-applied in the field. Corporate Headquarters Seattle, WA

CASE STUDY #2 Finish Coat: FEVE Fluoropolymer (Metallic)
The 75-foot high by 140-foot long facade features cast iron colonnades with ornamental castings and a cornice section made of galvanized metal. The amount of craftsmanship and handiwork that goes into restoring cast iron architecture like this is unbelievable, so this project required high-performance coating systems. Pitted cast iron pieces were reconditioned using a surfacing epoxy and primed with a zinc-rich aromatic urethane. Structural steel used to secure cast iron components to the building was blast-cleaned and primed by the fabricator with a zinc-rich coating. The façade’s cornice section was prepared in accordance with SSPC-SP1 Solvent Cleaning. “They originally tried abrasive blasting, but the sheet metal was too thin so they used a chemical stripper on the metal and pressure-washed it. The cornice section above the window bays were galvanized metal that was 100 percent shop-applied. The section was primed with an epoxy, followed by a finish coat of FEVE high-solids fluoropolymer resin that offers outstanding color and gloss retention. Among the custom colors specified was an elegant gold accent, matched to simulate 24-karat gold leafing, in Fluoropolymer Metallic. The Fluoropolymer was then topcoated with a Metallic Clearcoat, a clear coat used to both enhance the finish and extend the long-term weathering qualities of metallic pigmented coatings. Structural steel for these sections was primed with a high-build epoxy. During the recoating, the façade was surrounded by scaffolding and enclosed to help control environmental conditions. Tie-coats, finish coats and the gold accent finishes were applied with brushes, rollers and sprayers to the cast iron columns and individual decorative castings that were then reassembled and attached by screws.

SELECTING A SUCCESSFUL OVERCOAT SYSTEM

WHAT ARE WE COATING? Ferrous Metals Non-Ferrous Metals
Coil-Coated Metal Panels Photo Caption: For the roofs, a system utilizing a high-build epoxy with superior wetting for marginally prepared rusty steel and self-priming characteristics, followed by a topcoat of a high-solids fluoropolymer coating that provides an ultra-durable finish with outstanding color and gloss retention, was the best solution for extended protection and color stability.

WHAT IS THE EXPOSURE CONDITION?
Mild Atmospheric Aggressive Atmospheric Potential Chemical Contact Potential Abrasion or Impact

FACTORS THAT DETERMINE OVERCOAT SUCCESS
Evaluate the current condition of the existing coating system Determine a viable method of surface preparation Evaluate the geographic location (exposure conditions) Consider properties of various coating types Each overcoat opportunity is going to be unique. Here is a list of the items that will have to be considered when evaluating an overcoat candidate. The condition of the existing system will determine how extensive the surface preparation will need to be.

DELAMINATION RISK FACTOR
Adhesion / Film Integrity + Geographic Location Existing Film Thickness Adhesion of the existing system is obviously important, but alone, it cannot be the determining factor for whether an overcoat should be pursued. Geographic location is also important. Southern exposed portions of structures are always going to show more degradation (in the northern hemisphere). Freeze-thaw cycling is more aggressive the farther north a project is located. So is the existing film thickness. Similar to the roof on your home there are only so many layers that can be put down on top of original finish, before they need to be removed. These considerations altogether make up what we call the delamination risk factor DELAMINATION RISK FACTOR

CANDIDATE OVERCOAT SYSTEM
Delamination Risk Factor + Cohesive Stress Factor Once a delamination risk factor has been determined, it will be time to consider surface preparation options. There are many methods of surface pre, however, not all of them can be used in a given scenario. For instance, dry abrasive blasting on roofs is not likely ever going to be viable for these structures. Ultimately, the success of an overcoat is paid largely to the selection of the proper primer that can work given everything that is considered. Choosing the right primer is an important point, as the stress factor has a great significance when overcoating. Each primer has a different curing stress factor. CANDIDATE OVERCOAT SYSTEM

EXISTING COATING CONDITION ASSESSMENT
Degree of Rust ASTM D610 – Evaluating Degree of Rusting on Painted Steel Surfaces This test method provides visual representatives of types of rust, each one is associated with a different reason and helps the coating representative know what is occurring. This standard helps to determine the degree of rust of the existing coating. We know that no one has a coating that can go over loose rust, so anything loose must come off. Tightly adhered rust can be overcoated. Once we determine the surface preparation options the degree of rust is a key factor on what method is used. ASTM D 610: Rating scale 0 – 10 based on % surface area, Spot, General, or Hybrid, Pectoral examples provided

Adhesion ASTM D3359 – Measuring Adhesion by Tape Test ASTM D 3359 Method A : Rating scale 0 – 5, This is a common and effective way to evaluate the adhesion of an existing coating system. All that is required is a roll of pressure sensitive tape and a knife. Often called “X cut” adhesion for obvious reasons, this test can be used to achieve a numerical representation of adhesion. The results shown in the photographs show that the aluminum coating has poor cohesive strength. A thin layer of aluminum is covering the back of the tape once it is removed. These tests resulted in an adhesion value of “0”. However, this was a successful overcoat project. With the proper method of surface preparation, the thin weak layer of aluminum was removed and the underlying coating was sound enough to support an overcoat.

Adhesion ASTM D6677 – Evaluating Adhesion by Knife This test is commonly referred to as “knife adhesion”. There is a numerical value associated with the results from this test as well. It is subjective and can be evaluated differently by each user. However, one can gain a significant amount of information from this test if they are familiar with the specific coating being tested. Though it is more subjective than the “X cut” test, coating experts use knife adhesion extensively to make overcoat decisions.

ADHESION/FILM INTEGRITY
What is the total film thickness? How many coats of paint? How good is the adhesion to the substrate and between coats? Are there film defects such as cracking or blistering? What do we talk about when we discuss adhesion and film integrity? Here are photos from a roof project. The photograph at left shows the DFT gauge is reading a normal film thickness for the system in place and knife adhesion with a good rating for the system. On the right, you will see a significantly higher value right next to a defect in the film. This blister was likely caused by excessive film thickness at the weld seam. The middle photo shows the removal of the blister cap to measure the thickness of the primer underneath. This shows that the primer is the correct thickness, indicating that if the defect areas are removed, this system could be successfully over coated.

This photograph shows an extreme example (severely aged, severely cracked) to prove how important it is to evaluate aged systems. This photo is of an aged coating system on an exhaust stack at a power plant. This exhibits how severe an aged system can be and still be a candidate for overcoating. This particular project was overcoated with an acrylic mastic system which we will discuss later in the presentation.

OVERCOAT SYSTEM SELECTION — PRIMERS
Epoxies vs. Epoxy Mastics Acrylics vs. Acrylic Mastics Once we have the surface preparation portion dealt with it’s time to select a primer. Primer selection is very important. Without a good performing primer, the finish coat won’t last. Epoxies have been around for a long time and provide the best corrosion protection, however they do shrink when they cure and create high cure stress, and if you have a severely aged system this high cure stress may be too much. Epoxies also require the most aggressive cleanliness standards, WJ-4. You may be required to remove all aged coatings in order to use the epoxy primers. Epoxy mastics work much better, and wet surface better which creates better adhesion. They have much lower cure stress and are typically higher solids and cure slower. Offer good corrosion protection and allow use of power tools. However do have limited use below 50°F. Standard acrylics were the gold standard and technology has come along way. However, acrylics carry almost no cure stress. Some allow for power tools. With standard acrylics, you will be limited in finish coat selection. Acrylic mastics are fairly new on the coating scene, and are changing the game a little. Acrylic mastics carry no cure stress. Acrylic mastics have pigments which provide for good corrosion protection. This allows them to go over tightly adhered aged coatings, direct to steel in cases where you have rust and tighlty adhered rust, which makes the waterjetting standards ideal. They don’t require the use of expensive media. A game changing feature of acrylic mastics is they allow the use of a solvent borne high performance finish coat. There is limited use of these coatings when the temperature is below 40°F.

One side of the panel was coated with a highly sustainable FEVE fluoropolymer and the other with a polyurethane. Note the difference in appearance. Acrylic polyurethane was the gold standard for exterior high performance coatings a couple of decades ago, and still continues to be good quality product, when compared to the FEVE fluoropolymer you can see a substantial difference in color and gloss. When viewing the panel neither coating had substantial color change, however the gloss changes significantly on the Polyurethane side.

STRIPE COATING

AREAS SUSCEPTIBLE TO EARLY FAILURE

PREPARING THE SURFACE & STRIPE COATING
The Protective Coatings Glossary (SSPC 00 – 07) defines a “Stripe Coat” as: “A coat of paint applied only to edges or to welds on steel structures before or after a full coat is applied. The stripe coat is intended to give those areas sufficient film build to resist corrosion.” Typical surfaces that are stripe coated include: Crevices, Back-to-back members, Nut and bolt assemblies and rivets, Welds, Inside/outside corners Corrosion pitted steel, Built-up structural members and Other irregularly shaped surfaces. Thickness of Stripe Coats: Stripe coats are typically not measured because the irregularly shaped surfaces to which they are applied cannot be accurately measured with dry film thickness gages. The main goal when applying stripe coats is to control the thickness to be as thin as possible while still achieving complete coverage of the surface. Applying the stripe coat too thick can result in film defects such pinholes and cracking, and may also result in aesthetics issues. Actual Specification Verbiage

LEED v4 & v4.1 CREDITS RELATED TO PAINTS AND COATINGS SECTION CREDIT NAME Sustainable Sites: Heat Island Reduction Roof/Wall Indoor Air Quality: Low-Emitting Materials Paints & Coatings HPC can help in earning LEED points when used as a significant part of the design. The coating system won’t directly provide a point, but offering protection and/or long-term aesthetics will add value and sustainability to the structure and/or substrate. Sustainable Sites- Heat Island Effect-Roof: Minimizing urban temperature and slowing the heat island effect by the utilization of a reflective roof can contribute to a LEED point. Using a fluoropolymer coating system that can be air dried can meet the reflective requirement. The fluoropolymer coating can meet this requirement in a wide range of colors including some deeptone and dark colors Indoor Environmental Quality- Credit 4.2 (2009) and Credit 2 (v4): Low Emitting Materials-Paints and Coatings: Coating systems used in the interior, within the weatherproofed area of a project, cannot exceed the VOC threshold set forth by LEED. These VOC guidelines will be outlined in a subsequent slide. Source: U.S. Green Building Council

IEQ CREDIT: LOW-EMITTING MATERIALS
Coating Requirements VOC Content: All paints and coatings wet-applied on site must meet the applicable VOC limits of CARB 2007 SCM, or the SCAQMD Rule 1113 (June 3, 2011). Emissions: Paints and coatings applied to floors, ceilings and walls shall meet the VOC emission requirements outlined in CDPH/EHLB/Standard Method V1.2 (January 2017). VOC content limits are outlined within the listed standards. LEED has always had VOC content restrictions, but the Emissions testing is new to the v4 addition. The California Department of Public Health (CDPH v1.1) has guidelines for manufacturer certification. A product manufacturer has the right to either self-certify or maintain third-party certification for their products. Small-scale environmental chamber testing is a path to examine product emissions by measuring emissions and attempting to calculate the long-term impact of chemical emissions on indoor air. Although this testing is very expensive, it has become the most prevalent test for evaluating building materials for indoor air quality impacts. Source: U.S. Green Building Council

CASE STUDY #5 Received FEVE Fluoropolymer Finish Coat Observation Deck
With its bird’s-eye view of Port Canaveral, Florida, the outdoor observation deck on the top of Exploration Tower has visitors flocking to take in the scenic views of passing cruise ships and rocket launches from nearby Kennedy Space Center. To keep the viewing area looking its best for many years, the project’s designers specified a fluoropolymer coating system. “They were looking for long-term color and gloss retention. “Recoating the elevated steel would be incredibly difficult, so they wanted to avoid having to do maintenance painting for many, many years.” The entire coating system was shop-applied by the steel fabricator. “The arches above the observation deck were brought out to the site preassembled and lifted into place with a large crane. The four-coat system was spray-applied over steel that was prepared in accordance with SSPC-SP10/NACE No. 2 Near-White Metal Blast Cleaning. The complete system was an aromatic zinc-rich polyurethane, a water-based epoxy, an aliphatic Polyurethane, and a finish coat of fluoropolymer Observation Deck Port Canaveral, FL
