References to "AcryShield" include "AcryShield A405", "AcryShield A500", "AcryShield A550" and "AcryShield A600", etc.

"AcryShield II" or "Acryguard" with 35 lbs/sq of roofing granules embedded into the topcoat may be substituted for "AcryShield" in any of the following systems.

"AcryShield II" or "Acryguard" without granules may be substituted for "AcryShield" in any of the following systems: max incline shall be limited to 3/4 in.

"AcryShield II" or "Acryguard" may be substituted for "AcryShield" in any system surfaced with "RoofGuard".

One-half in. thick (min) gypsum board or 1/4 in. thick (min) G-P Gypsum DensDeck® may be used in any existing noncombustible deck Classification. When this is done, the resulting roofing system is acceptable for use over combustible (15/32 in. min) roof decks. The joints in the gypsum board and overlayment board are offset 6 in. with the joints in the deck.

35 lbs/sq of roofing granules embedded into an additional 1-1/2 gallons of "AcryShield" may be added to any of the following systems.

Any thickness isoboard may cover a metal deck under any of the following systems, without changing the Classification, as long as the spray foam has a min thickness of 1-1/2 in. The total insulation thickness (polyisocyanurate and spray foam) shall not exceed the max thickness limitation of the spray foam.

"DuraTuff" may be used in place of "AcryShield" in any of the following systems.

"AcryShield Basecoat" may be used for the first coat(s) in any of the following systems, as long as at least 1-1/2 gallons of "AcryShield" is applied for the topcoat.

"AcryShield" , "Acryguard" or "AcryShield II" (max 3 gal/sq) coating is suitable for use over any Siplast modified bitumen roofing system up to a maximum incline of 3/4 in.

"Acryguard" may be used in lieu of "Acryshield II" in any applicable system.
