There is no easier way to waterproof your commercial roof than spray applying a monolithic membrane on top of your existing, failing roof.

AcryShield roof coating systems are installed in a few simple steps: a layer of AcryShield base coat with polyester reinforcing fabric embedded into the base coat if necessary, and lastly a layer of AcryShield top coat. These systems are applied over a wide range of roofing membranes to give your existing roof superior waterproofing, industry leading UV protection, dirt pick-up resistance, tenacious adhesion and resistance to ponded water.

A few reasons the AcryShield coatings provide ease of application:

• Applying an AcryShield roof coating systems over your existing roof eliminates a costly and timely roof tear-off.
• These systems are spray applied, removing any need for patching and sealing areas around HVAC equipment, pipes, skylights, etc… These systems are sprayed around those hard to reach and hard to seal areas to create a seamless system for excellent waterproofing.
• No business closure during installation. Throughout installation, there are minimal noise disruptions because there is no drilling, nailing or seam welding during application. The roof coatings used in these systems contain low or even ZERO VOC’s, with no harmful or strong odors, allowing you to keep your business open.
• The AcryShield A502 basecoat eliminates the need for traditional primers or etching rinses to be applied and captured before the base coat can be applied on top of EPDM, Hypalon or TPO. This allows contractors to eliminate installation stages and building owners to save money.
• Installation time is fast with minimal steps and can even be quicker when using the AcryShield Quick-Set base and top coats. These Quick-Set products are formulated to set rapidly in order to resist early wash-off associated with heavy dew and light rain.

Spray Polyurethane Foam or SPF roofing is excellent for restoring your current roof or as a new construction project. The foam used in these systems must be coated with a roof coating in order to provide the SPF roof with adequate protection needed from deterioration caused by the sun’s Ultra Violet (UV) radiation and water infiltration. 

Acrylic roof coatings are among the most popular in the roofing industry for protecting SPF because of their strength and ability to adhere to the spray foam. These coatings have a long history of success (check out our SPF Case Histories), high quality ingredients, and fire retardants that work together to construct a seamless, durable, and flexible membrane with excellent resistance to UV destruction and water penetration. 

When you combine SPF roofing with an acrylic roof coating system, you gain the strength and protection needed for the roof to function properly, as well as, excellent insulation, custom slope and superior reflectivity. These systems provide customizable levels of insulation to reduce heat loss and gain to the building, allowing your building to remain a consistent indoor temperature with less need to heat or cool the building. Custom slope can be created with the spray polyurethane foam for improved proper water drainage and ponded water protection.  High solar reflectance and thermal emittance properties gained from the acrylic roof coatings ability to reflect the sun’s heat away from the rooftop, lowers energy cooling costs and contributes to the reduction of heat transfer to the inside of the building, allowing the building to remain cooler on a hot day.

National Coatings has several SPF roofing systems coupled with acrylic roof coatings to provide all the benefits mentioned above. With over 33 years of proven performance, the AcryShield SPF Roofing Systems can decrease your energy consumption and costs. This is a huge reduction in cost based off California’s energy-efficiency movement - Flex Your Power© which states “A 30% reduction in energy consumption can lower operating costs by $25,000 a year for every 50,000 square feet of office space.” If you are interested in more information on SPF Roofing or the Benefits of Coating an SPF Roof, download our FREE Guide.
