Specifier's can Count on High-Quality, Long-Lasting Roofing Systems with Low Installation Costs when they Select National Coating's Roofing Systems for their Clients

Posted by Nicole Gale on Wed, Apr 03, 2013 @ 11:00 AM

Long-Lasting Roofing Systems  

National Coatings has four superior roofing systems for either roof maintenance, restoration or new construction: AcryPly Roof Restoration SystemAcryShield Roof Management System (ARM), AcryShield Sprayed Polyurethane Foam (SPF) System and the AcryPly-D Deck Up System. All our systems have excellent benefits, longevity, and low installation costs.

UNBEATABLE FEATURES AND BENEFITS

These four systems have unbeatable product features and benefits. They use a non-intrusive application process, minimizing any installation disruptions and allowing you to keep your organization open for business during the process. With quick installation, these systems are easily applied - no drilling, nailing, fasteners or seam welding. AcryShield Quick Set products are available to set quickly, resisting early wash-off associated with heavy dew or light rain. The AcryShield coatings create seamless roofing membranes, customizable to meet specific needs of a customers roofing substrate. AcryShield coatings are watertight, providing additional layers of waterproofing, superior adhesion to your existing roof membrane, and resistance to ponded water. These coatings are rich in UV blocking ingredients, providing excellent protection to your roof and reducing roof maintenance costs. The UV protection against sun damage and UV rays, which are the leading causes of roof degradation, allow your roof to last substantially longer than a traditional, non-coated roofs. 

LONGEVITY

Our roofing systems are renewable, environmentally friendly systems, designed to extend your roof's life indefinitely. The AcryShield Roof Management System (ARM) or AcryPly Roof Restoration System applied to your roof approximately every 10 years will preserve and enhance your current roof, keeping it watertight without ever having to worry about a costly tear-off.

LOW INSTALLATION COSTS

National Coatings AcryShield Roofing Systems are the most cost effective method for long-term roof asset management. The installation of these systems are quick and trouble-free. They have the ability to self-flash without cracking or bending and require no need for welding, adhesives, fasteners, or boots. The use of roof maintenance coatings can indefinitely defer reroofing and the even higher cost of tear-off and replacement. In most cases, the roof life cycle cost is lower with an AcryShield Roofing System than other traditional reroofing options.

National Coatings Roofing Systems deliver superior product performance while providing supreme benefits, unmatched by other roofing substrates. For more information on our systems contact us on the web or call 800-423-9557.

National Coating's Received New ICC-ES Report for International Building Code (IBC) Compliant Roofing Systems

Posted by Nicole Gale on Wed, Mar 06, 2013 @ 09:00 AM

 ICC ES Report

"We are very proud of this report and know our highly rated products will benefit the roofing industry." says Matt Kolb, President of National Coatings Corporation "These building codes set stringent regulations and National Coatings Systems undoubtedly have proven their superior quality and performance capabilities."

Why is the ICC-ES Report Important?

The new ICC-ES Evaluation Report (ESR #2140) provides evidence that our AcryShield® Roof Management (ARM), AcryPly® and SPF Roof Coating Systems meet code requirements. 

How Difficult is it to Get a Report Like This? 

ICC-ES thoroughly examined all of National Coatings product information, test reports, calculations, quality control methods and other factors to ensure the products are code-compliant. 

Who Uses the ICC-ES Report and Why? 

This new report is utilized by building officials, architects, contractors, specifiers, designers and others to provide a basis for using or approving roof systems in construction projects under the 2009 and 2006 International Building Code.  

Can I Use National Coatings ICC-ES Approve Roofing Systems in Any Project?

The systems listed in this new report are ideal roofing systems for new construction, restoration, maintenance and roof repair.

Determining Dry Film Thickness for Roof Coating Using a Wet Mil Gauge

Posted by Nicole Gale on Mon, Jan 16, 2012 @ 02:35 PM

DIRECTIONS FOR USE:

  • Press gauge into wet elastomeric roof coating.

  • Withdraw vertically and note deepest tooth having paint on it and the next higher tooth that is not coated with paint.

  • The true wet film thickness lies between these two readings. Clean gauge after each use.

Elastomeric Roof Coating Wet Mil Gauge

DETERMINING THE DRY FILM THICKNESS (DFT) AFTER FINDING THE WET FILM THICKNESS:

Many roofing specifications and warranty policies call out for a certain number of dry film thickness mils to be required on a job.  The wet mil gauge gives you one of the numbers needed in the formula to determining the dry film thickness.  The other number you will need to know is the volume solids of the elastomeric roof coating.  Here is the formula:

 Wet Film Thickness x Percent Volume Solids = Dry Film Thickness (DFT)

Let’s use a specification from National Coatings as an example.  The specification calls for 24 mils DFT of elastomeric roof coating AcryShield A503 base coat & AcryShield A400 top coat.  Let’s first take the AcryShield A503 base coat. It has a 54% solids material – the contractor will need to apply 1 ½ gallons (these quantities are based on perfect conditions, perfect spray equipment, no wind, etc…see "Things to Consider” below) per square to achieve approximately 24 wet mils. Using the formula above we will take 24 and multiply it by 0.54 to find out the DFT equals 12.96.  When the base coat is dry, the AcryShield A400 top coat will also need to be sprayed at 1 ½ gallons per square to reach 24 wet mils. This top coat has a 52% volume solids content, so we will take 24 mils and multiply it by 0.52 to find out that the DFT equals 12.48. When you add the 12.96 DFT of base coat and 12.48 DFT of top coat, you are left with a roof membrane that is 25.44 mils DFT which slightly exceeds the specifications requirement of 24 mils DFT. 

THINGS TO CONSIDER:

  • When measuring the wet film thickness, you must do so immediately after the application of the roof coating. If the coating has a high concentration of volatile solvents (liquids that vaporize at room temperature), they will evaporate immediately giving a false reading.

  • Wind Loss:  Winds up to 20 miles per hour, you may lose 20%-30% of the coating required.

  • Miscellaneous Loss:  Add between 3% to 10% to the total coating required (extra coating required due to lapping of the coating between passes and coating trapped in the lines and in the empty pail/drum)
