Many High-Performance products are two component catalyzed or unique curing systems that demand strict adherence to all technical data and guidelines.

Below is a routine checklist of sound practices and procedures:

 1) Before beginning, review all project specifications closely and read all technical data thoroughly.

2) Stage all materials before starting and double check that all the proper products, components, and quantities are on hand.

3) Make certain that all products are within the usable shelf-life dates.

4) Carefully follow all mixing instructions.

5) observe all mixing ratios, rates, and order of addition – i.e., Component B is added to Component A.

6) Provide efficient and thorough mixing of all products and allow for proper “sweat-in”or induction time.

7) Only mix enough material to be applied within the recommended working time or pot-life of the product.

8) Measure temperatures and make sure they are within allowable application ranges and note where cold or hot temperatures can slow or accelerate performance/application parameters.

9) If using thinners – only use recommended thinning agents.

10) Once the coatings are prepared make sure that the recommended application tools employed are high quality, clean and in good working condition.


Flooring system applications can be broadly grouped into two types; thin film (5-8 mls) and thick film (13-20 mls) systems.

Thin film applications are usually 2 coat systems; penetrating epoxy sealer/Pre-Prime and clear coats like moisture cure urethane finishes and lend themselves to brush, roll (3/8”nap max) and spray.

Thick film applications are normally 3 coat systems comprised of penetrating epoxy sealer/Pre-Prime, intermediate coat, and finish coat.

Tool requirements include brushes, squeegees and a variety of roller types; lambskin, phenolic core and porcupine.

Always refer to the technical data sheets for application recommendations for specific products and systems.


The reaction of the epoxy sealer with the bare concrete performs a very important function of preventing “outgassing” with the subsequent topcoats.

Outgassing is a phenomenon where a liquid coating/topcoat reacts with unsealed concrete and gas is generated causing bubbles to form that become trapped in the finished film.The primer/sealer coat is poured or sprayed onto the floor and then evened out by brush, roller or squeegee.

All new or bare properly prepared concrete should receive a 100% solids epoxy Pre-Prime to provide a beginning foundation that forms a chemical bond within the concrete, satisfying the thirst and porosity of the substrate.


Pour ribbons of the mixed coatings onto the floor then spread with squeegee, roller, lambswool applicator, or phenolic core roller. Lightly backroll with lint-free phenolic core roller perpendicular to the original squeegee orientation.

Avoid over rolling as it may cause appearance uniformity problems. Since many flooring systems are multilayer coats on large expansive areas, spiked shoes are routinely used by applicators so that they can walk into freshly coated areas to re-roll, even-out, lap, blend-in or broadcast aggregate or other materials into the finish while wet.

Porcupine rollers are used to smooth the surface coat and release entrapped air in the finish. Notched squeegees and rakes are used to apply high solids/ high build finishes at evenly controlled wet film thicknesses.


Hand broadcast aggregate to recommended profile approximately 2 lbs per 100 square feet up to one hour after application.

National Painting & Coatings Company Supplying Protective Coatings For Massive Cleveland Innerbelt Bridge Project

Epoxy intermediate coating Macropoxy 646 provides high-gloss protection from harsh Northeast Ohio weather for vital city artery

A leading National Painting & Coatings Company Supplying Protective Coatings was chosen by Atlantic Painting (Oak Lawn, Ill.) to supply high-performance protective coatings for the Ohio Department of Transportation’s (ODOT) I-90 Innerbelt Bridge project. Coating work is now underway on the 1.8 million square feet of steel that comprise the westbound span over the Cuyahoga River. Reconstruction of the bridge, which opened to traffic in 1959 and is the main east-west artery into and through downtown Cleveland, is the largest project in ODOT’s history. The new bridge, which is north of the existing span, will be 4,247 feet long and stand 120 feet over the Cuyahoga River Valley at its highest point.   Tank Lining & Coatings Kentucky Indiana.

To give the bridge a high-gloss finish and protect the structure from the harsh Cleveland elements, Sherwin-Williams will supply Macropoxy 646, an epoxy intermediate coating, and HP DOT Acrylic Polyurethane, a high-gloss top coat in off-white, for the project. The company is also providing Zinc Clad IV organic epoxy that will be used by Atlantic’s field painters to touch up the shop-primed steel sections and splice plates. More than 26,000 gallons of coatings will be used for the project.

“ODOT needed high gloss, a low film build of 2-4 mils with higher-build performance, superior weathering, and ease of application,” said  regional market director, bridge & highway,  “These products will achieve all of those requirements. As a company headquartered for nearly 150 years in Cleveland, it is gratifying to be an asset protection partner on an infrastructure project that is such a vital link to the city from points near and far.”

Although not all states require steel bridges to be coated, ODOT does stipulate protecting its bridges in this manner.   Bridges in Northeast Ohio must stand up to some of the most rigorous inspections there are, given the constant expansion and contraction caused by thermal cycling, and exposure to road salt and airborne contaminants from Lake Erie winds.

The project design and product specifications address these issues. Because of the level of degradation and corrosion that can occur at structural joints, ODOT wanted to limit their number. The old bridge had joints at every one of the 14 piers, but in the new design there are only two.

In addition, QUV accelerated weathering tests (5,000+ hours of UV exposure is Ohio’s standard) and field experience document the superior gloss retention of the topcoat, which doubles the maintenance-to-recoat cycle. “Our testing demonstrates gloss retention even after 9,000 hours of exposure. This considerably extends the lifecycle of the coating and provides unprecedented value for the taxpayers,” he noted, saying the bridge would likely only need to be repainted two or three times during its design life of 75 years.

The project is unusual in several ways. ODOT used a value-based design-build approach (vs. design-bid-build) for the first time, to expedite the work and minimize disruption to both local motorists and those traveling between Chicago and the Northeast US.

In addition, the bridge’s architecture has distinctive delta-shaped girders that complement the Cuyahoga Valley topography without dominating it. The design teams that competed for the work were evaluated on their ability to deliver on not just cost and an ambitious schedule, but also on preserving the aesthetics that define this part of Cleveland’s landscape. The project was awarded to general contractor Walsh Construction in partnership with HNTB Corporation, the lead architectural and engineering design firm, and HDR, the independent quality engineering firm.
