HOW ARE FLUID-APPLIED SYSTEMS SUSTAINABLE?

THE KEYS FLUID-APPLIED SYSTEMS

• Proven Performance

• Higher Performance

• Fully Sustainable

• Ease of Installation

• Ease of Maintenance

WHO ARE THE BEST CLIENTS?

• Low Slope Commercial / Industrial / Institutional

• Typically Own the Property for an Extended Period

• National & International Corporations

• Municipalities

• Hospitals

• Military

• Multi-Facility Owners

WHY BUILDING OWNERS CHOOSERESTORATION VS RE-ROOFING

• Technical and Economic Benefits

• Minimal Disruption During the Installation Process

• Ease of Maintenance

• Environmentally Friendly Systems

• Hybrid systems available if restoration alone not possible

TECHNICAL BENEFITS

• Liquid applied restorations provide a seamless system (seams are the weak points in any system)

• Highly reflective (among the most reflective in the industry averaging 85%-90% reflectivity)

• Cooler roof surface translates into Energy Savings & Cooler Interior

• Resistant to Ponding Water (some can handle 72-hour standing water)

• Easily renewed (Sustainable); easily repaired because material bonds to itself

EXPENSE LOWERING BENEFITS

• Save on the initial system compared to most “conventional” application methods

• Fully tax deductible as an operating expense, classified under maintenance

• Lower utility expenses • Eliminate the expense of replacing the insulation• Economical maintenance• Long-term ROI improves due to lower cost of subsequent

restorations

• Overlays require a cover board; fasteners create thermal gaps reducing effectiveness of new insulation

• Long-term SRI is better for high-performance coatings than for many sheet goods

• Emissivity of coated roofs comparable to or better than sheet goods

• Condensation point is not raised into roof assembly with restoration

BUT WHITE ROOFS ARE ALL THE SAME. AREN’T THEY?

• Different chemistries impart different physicals

• Appropriate uses vary• Differences in cost• Single component vs.

multi-component

DIFFERENT CHEMISTRIES IN ROOF COATINGS

• Lowest tensile and elongation (both > 400)

• Cannot handle standing water

• Low chemical and impact resistance

• Waterborne = low VOC/odor, easy cleanup

• Inexpensive

• No solvents = reduced bitumen bleed

• Single component

ACRYLICS

THE GOOD THE BAD

URETHANES

There are two classes of urethanes: aromatic and aliphatic. Each has strengths and weaknesses.

AROMATIC

•Less expensive

•Better elongation

•Prone to chalking

•High millage loss

•May need accelerant in arid climates

ALIPHATIC

•Better UV resistance

•High impact resistance/durable

•High odor

•High cost

•Require catalyst, long cure

SILICONES

THE GOOD THE BAD

• High UV resistance

• Good initial physicals

• Single component

• Loses physicals rapidly

• Noncompatible with other systems

• Prone to discoloration

SEBS

THE BAD

• Proven track record• Superior physicals, stability• Chemical cure -- not

dependent upon weather• Single component• Good resistance to

chemicals and ponding

• Initial odor

• Solvent cleanup

• Higher cost

THE GOOD

POLYUREAS

THE GOOD THE BAD

• Rapid cure under any conditions

• High solids

• Low odor

• Plural component = high margin for error

• Improper mixing results in inconsistencies

• High cost

PMMA

THE GOOD THE BAD

• Short cure time

• Resistant to ponding water

• May be installed in wide range of temperatures

• Poor chemical resistance

• High cost

• Strong odor during install

• Lower adhesion strength

Chemistry lesson is over!!!

THE OBJECTIONS

• This isn’t a finished roofing system.

• These systems have to be field-assembled.

• I don’t want to order caulking, sealants, etc. from multiple sources.

• Fluid-applied systems can’t handle standing water.

• This guy is an idiot and is selling us a line of bull.

• “We’ve all seen the failures.”

THE OBJECTIONS

THE ADVANCES

• Fibered mastics now offer one-step seam and curb detailing. Some manufacturers now offer a complete system including caulking, emulsions, etc.

• There is no poly to tent or fishmouth. Random orientation of fibers means higher tensile strength and less sacrifice of elongation.

• Factory reps now trained in infrared analyses, moisture probes, newer substrates, etc. We are a resource for specifiers and contractors alike.

THE ADVANCES

• Simplified systems

• Less room for error

• More competitive bids—less labor!

• Quicker installation = reduced disruption

• Waterborne and high-performance systems available

• Quality control improved by single-source manufacturing

• Adhesion tests routinely done by manufacturers

• In-house technical services

• Better contractor education

ROOF RESTORATION—THE ADVANCES

Existing Roof Detailed with Mastic

Base Coat Completed Sustainable Cool Roof

METAL ROOF RESTORATION—THE ADVANCES

NEW CONSTRUCTION

• Coatings provide renewable system

• LEED points available

• Benefits of monolithic system

LIFE CYCLE COSTS100,000 SF – 30 YEARS

• Single ply: $200k initial install + $250K overlay at 15 years + $350k

re-roof at 30 years = $800k• Fluid-applied: $250k initial install + $125k recoat X 3 (every 10 years)

= $625k

It’s time to consider this option!

EXTERIOR ENVELOPE

• Exterior Wall Restoration

• CMU, Brick, Concrete, Stone, EIFS and more

• Available in clear and color options

• Options in waterborne and higher-performing materials

CONCRETE RESTORATION

• Inhibits vapor drive through slab

• Retards wear and provides stain resistance

• Provides slip resistance when aggregate added

• Possible uses: plaza decks, flooring, concrete roofs

FERROUS METAL RESTORATION

• Superior Shore A hardness

• Better chemical resistance than paint

• Less respraying equals less down time—lower costs!

•Leak Free

•Durable

•Long Lasting

•Cost-Effective

•System Warranty

•Ease of Maintenance

•Sustainable

•Greatly Reduce Landfill Waste
