Acrylic Top Coat Options for SPF

• AcryShield A500 is an excellent coating choice for both base and top coat over SPF roofing. It provides longevity and brightness with superior dirt pick-up resistance and protection against biological attack such as algae. AcryShield A500 exceeds all ASTM D6083 requirements and also offers excellent tensile strength, elongation, and wet adhesion.
• AcryShield A510 can be applied as a base and top coat for SPF. It was developed for areas where additional fire retardant packages are not required. AcryShield A510 also exceeds all ASTM D6083 requirements and also offers excellent tensile strength, elongation, and wet adhesion.

 Acrylic Base Coat Options for SPF

• AcryShield A501 base coat is the industry leading, high performance base coat with optimum adhesion to SPF roofing. A501 provides an additional layer of waterproofing, superior adhesion, and resistance to ponded water.
• AcryShield A410 base coat is a low-perm elastomeric coating, specifically designed for the exterior of buildings and rooms where there is reverse vapor drive (cold storage, food packing plants, etc.)

Silicone Top and Base Coat Option for SPF

• SRC 720 and SRC 740 silicone base and top coats deliver ultra low VOC coatings with high solids. These coatings create a one-component, moisture-curing silicone roof coating system that can be applied in excess of 30 mils in a single coat while maintaining maximum adhesion without blistering due to the high solids content and absence of hydrocarbon solvents. 

Extra Foot Traffic and Physical Abuse Protection Option

• AcryShield A550 can be both a base and top coat, it has double the toughness of any other AcryShield coating. With its urethane-like strength and elongation properties, this acrylic product is excellent for superior protection against foot traffic and physical abuse. AcryShield A550 also exceeds all ASTM D6083 requirements and also offers excellent tensile strength, elongation, and wet adhesion.

Ultra High Reflectance Option

• AcryShield A590 base and top coat has ULTRA high reflectance with superior UV protection and low VOC's. It lowers air conditioning energy costs, reduces roof degradation, and prolongs the lifespan of the roof. A590 also exceeds all ASTM D6083 requirements and also offers excellent tensile strength, elongation, and wet adhesion.  

SPF Fast Setting Option

• AcryShield Quick Set base and top coats are specifically formulated to resist early wash-off associated with heavy dew and light rain. Ask about our different quick set products for SPF.  Base and Top coats: A600, A610.

Granules

• RoofGuard Granules are specifically designed for use with high performance AcryShield® roof coatings and are the superior choice for SPF roofing applications. These granules enhance the appearance of the SPF roofing system while delivering added durability, improving impact and foot traffic protection.

Hurricane season is quickly approaching beginning May 15th in the Eastern Pacific and June 1st in the Atlantic lasting through the end of November. For low sloped, commercial buildings in these regions it is important and necessary to install a roofing system that can withstand extreme wind uplift while providing waterproofing capabilities during hurricane season to guarantee protection and coverage to your building and the assets inside. 

Spray polyurethane foam roofing systems or SPF roofing systems can do just that! They have excellent waterproofing capabilities and provide wind uplift protection. The SPF roof systems are sustainable and quick to install, as they are spray applied directly over your existing roof, allowing you to restore and renew your roof rather than replace it.

Waterproofing Capabilities

The spray application allows a custom slope to be created where necessary to improve and correct any water drainage and ponded water issues. Spraying each layer of the roofing system directly on the roof top also provides a 100% seamless and monolithic roofing system ensuring excellent waterproofing protection across the entire roof and especially in hard to reach and seal areas such as around rooftop equipment, skylights, pipes, drains and other items. Seamless roof membranes are flexible with an even amount of tension across the entire roof field. This is unlike systems with seams (such as single-plies), which experience a lot of tension at the joints and seams causing tears and rips to occur over time – eventually leading to water penetration into the roof deck.

Excellent Wind Uplift Protection:

SPF roof coating systems are composed of many closed-cells, which provide durable structural integrity to the roof and excellent adhesion to the roof deck and walls it is sprayed onto. These systems have such great adhesion capabilities they have been proven to withstand recent hurricanes such as Katrina and Rita and scored above average scores when tested in hurricane conditions by the National Institute of Standards and Technology (NIST).
