APA is a new revolutionary, zero VOC, non-conventional exterior, 100% polyurea coating. This product has been designed specifically to deliver the toughness and abrasion resistant properties of that of an aromatic polyurea but provides the capability of retaining color-fastness for a full range of pigmented colors. Unlike conventional aromatic polyurea, which in a white pigmented system turns yellow in hours when left in direct sun light, APA systems can withstand direct harsh sunlight experiencing no color change after 1 year. APA is available with different hardness and reactivities. APA is available in 2 versions – horizontal and vertical. Horizontal APA has a gel time of approximately 30-45 seconds allowing the ability to broadcast into it if desired, whereas Vertical APA is a quick set material allowing to be sprayed vertically without running. APA has excellent adhesion properties allowing it to be sprayed on all types of surfaces including spray foams. APA complies with FDA 21CFR 175.105 and 21 CFR 175.300. APA is also available with fire retardant additives. These additives allow APA to meet ASTM E84 Class A. APA uses a mix ratio of 1A – 1B. APA may be applied using high pressure heated plural equipment, low pressure heated equipment or using cold spray 2K cartridge equipment. Recommended heater settings are 140°F for both primary heaters and hose heater. Machine pressure should be set at around 2000 psi.
Application temperature ranges from 40°F – 125°F. APA may be applied using a 2-component, high pressure spray machine or cartridge gun application. Substrate surfaces must be clean, dry and free of contaminates and dust. Substrates must be free of loose rust, paint, moisture, dirt oils, etc. If application surface exhibits extensive corrosion, spalling and/or weak deteriorating substrate, normal forms of media or shot blasting is recommended to create a secure surface preparation. For conditions which may only require liquid washing and cleaning with detergents, acids, bio-enzymes, etc. or conditions involving processes of scrubbing, rinsing and drying, the finish surface must not retain any residual cleaner unless specified by Superskinsystems, Inc. Concrete must be fully cured and should be prepared with shot blasting, diamond grinding or machine sanding depending on the severity of the concrete surface condition. Similar proper preparation must be performed for metal surfaces. Primers are recommended for proper preparation. Always power clean using mild detergent prior to sanding, etc. Spray coverage at 16 mils is 100 sq. ft./ mixed gallon.
