Fast setting coatings


National Coatings’ Quick Set roof coatings are excellent for use during Fall because they prevent early wash-off related to light rain and heavy dew weather conditions. The Quick Set coatings are ideal for restoring and maintaining your rooftop in a hurry.

Our watertight base and top coatings not only allow for quick installation but also provide a non-intrusive application process. These renewable systems eliminate the need for a costly and timely roof tear-off and provide cost effective solutions while reducing roof maintenance throughout the roofs lifespan. The AcryShield Quick Set coatings products can be applied on most roofing substrates, including:

  • BUR
  • Mod Bit
  • Asphalt
  • Hypalon
  • EDPM
  • TPO
  • PVC
  • Metals
  • SPF
  • Concrete 

It can be challenging for a contractor when heavy dew or light rain are forecast soon after initial application has begun, but National Coatings is here to help.  Contact us NOW for more information 800-423-9557.


Acrylic AcryShield QuickSet Coatings can be used in the following systems:

Acrylic AcryShield QuickSet Base Coats:

    • AcryShield A602 is a quick-set base coat with low VOC's.  This high performance base coat has the technology to coat directly over hard to coat substrates such as Hypalon, TPO, and EPDM. A602 eliminates the need for costly TPO and PVC membrane replacement, and pre-treating EPDM with a caustic solution before the coating is applied.

    • AcryShield A603 is a quick-set base coat with low VOC's. It is a water borne coating for surfaces such as Concrete, BUR, Mod Bit, and Asphalt Emulsion. A603 has superior protection against ponded water. 

Acrylic AcryShield QuickSet Top Coats:    

    • AcryShield A600 is a premium elastomeric quick-set top coat that has optimum adhesion over SPF, Metal and Concrete and is excellent where extra levels of low temperature flexibility are required. A600 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion, and weatherability. It also includes a fire retardant package.

    • AcryShield A610 is a premium quick-set top coat that is excellent where extra levels of low temperature flexibility are required.  

    • AcryShield A640 is a premium elastomeric quick-set top coat that has unique bleed blocking properties that make it particularly suited for coating over Asphalt, BUR, and Mod Bit surfaces. A640 can also be coated over Metal, and Concrete. A640 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion, and weatherability.

Common Roofing Issues that Need to be Repaired Immediately

Posted by Nicole Gale on Tue, Oct 16, 2018 @ 08:00 AM

Common roofing issues

The following 6 pictures show common roofing issues that occur to roof tops that have not be properly checked on or maintained. By continuing to avoid or overlook these issues, an expensive roof repair project can be in your future. The good news is, if they are addressed and properly fixed, you will save yourself a lot of time and money. Check out our article "Can My Roof Benefit from a Roof Maintenance System?"


Ponded Water: Ponded water leads to delimitation, blistering, peeling and compromised adhesion of the roof system to the buildings substrate. This issue needs to be fixed immediately. To remedy ponded water, the AcryShield SPF Roofing System allows you to create a custom slope in areas where ponded water typically occurs, allowing the standing water to flow towards proper drainage.


Impacted or Clogged Drainage: A plumber is recommended to unclog the drain and then the ponded water needs to be inspected to make sure no further damage has occurred. (See Ponded Water above more information.)


Large Blister: Blisters occur because of several reasons, including: adhesion issues, ponded water, an aging membrane and more. This is another issue that needs to be fixed immediately as water penetration is likely. Contact a Roofing Professional with zero obligation to determine your next steps to restoring your current roof.


Debris from Overhanging Trees: It is necessary to cut back branches that hang over the roof top because they can cause abrasions to the surface of the roof and leaves and branches can clog drains and create ponded water issues. It is important to ensure the roof is clean and free from any debris.


Mastic Cracking at Pipe Jack: When seals are failing and not functioning as designed, water penetration can occur. All joints and flashings need to be inspected to ensure seals have good flexibility (not brittle), adhesion, and water resistance.


Plant Growth: Weeds, trees, and plants can grow out of the smallest cracks on your roof. Carefully remove any form of plant growth immediately as this can cause several issues including: improper drainage, damage from roots, inadequate adhesion, ponded water, etc… Do not pull or yank the plant from the roof as the roots may have penetrated through the surface and this could cause even more damage. Contact a roofing professional if you think this could be the case for your roof.

National Coatings is here to help you. If your roof has any of the above issues, contact us. We will provide you with a cost savings solution that will allow you to restore and maintain your current roof without any business closures or disruptions.

Inspect your roof

  • InspectionClear all debris off the roof (dirt, rocks, branches, leaves, etc…)
  • Clean out drains and gutters to ensure proper drainage can occur, preventing ponded water
  • Remove any overhanging tree branches or anything else that could penetrate the roof surface
  • Install walk pads in high traffic areas - especially around roof hatches and equipment systems
  • Inspect and insure all equipment is properly flashed and watertight
  • Inspect all areas for leaks and deterioration – pay attention to stains and discoloration of the roof edges and surrounding walls as they are possible indications of a leak
  • Take note of any trouble areas that could cause leaks, damage or deterioration and call your National Coating representative 800-423-9557 for further guidance.
