Description

United Asphalt‘s Armour Proof AP-5400 High Solids Silicone Roof Coating is an exciting, new high yield, low VOC one-part silicone elastomeric roof coating! It was specifically designed as a protective coating over a variety of roofing substrates. Once cured, this liquid applied silicone coating provides a durable, seamless, flexible, waterproof membrane that resists lateral movement, shear and will allow for normal expansion and contraction. AP-5400 High Solids Silicone Roof Coating, when compared mil for mil, provides greater UV protection than similar silicone coatings and offers increased resistance to moisture penetration. AP-5400 provides excellent long term protection through exceptional weatherability properties.

Coverage and Drying Time

Apply AP-5400 at the rate of 1.5 gallons per square. Minimum dry mil thickness shall be above 20 mils. Two passes of silicone and a primer coat may be required for some applications and warranty programs. PRODUCT APPLICATION SHOULD BE SUSPENDED IMMEDIATELY AND OUR TECHNICAL SERVICE PERSONNEL CONTACTED IF THE RESULTS BEING OBTAINED ARE LESS THAN DESIRABLE. Refer to the Armour Proof Coatings Specification for detailed instructions.

Application

AP-5400 High Solids Silicone Roof Coating may be applied by medium nap rollers, soft brushes or high pressure airless spray equipment. Apply AP-5400 only to clean, dry, sound surfaces free of loose particles or other foreign matter. For best results, ambient temperature should be between 50-90°F. Higher temperatures will shorten the cure and working times for proper application of granules before the material has skinned. Lower temperatures will lengthen the skinover, tack free and ultimate cure time. Sudden temperature declines may also result in dew formation on surfaces, which can prevent adhesion development. For best results, relative humidity should be above 20%. Lower humidity will slow the cure time significantly.

Suitable Roof Substrates Use as part of a System
