MANUFACTURER CELCORE INCORPORATED 775 US Hwy 70 West Black Mountain, N.C (704) (704) Fax 3. PRODUCT DESCRIPTION Basic Use: Celcore Foam Concentrate is mixed with water and generated into a preformed foam for addition to cement/water slurry mixtures to create a closed cell cellular concrete of a specific density. Typical air dry densities are in the range of pcf. Oven dry densities are in the range of pcf. Typical uses for Celcore Cellular Concrete are poured-in-place insulating applications and geotechnical fills. Celcore Cellular Insulating Concrete is a key component of a Celcore Cellular Insulating Roof Deck System. Celcore Cellular Insulating Concrete may be used in conjunction with expanded polystyrene board to produce a thermally efficient, fire rated, Underwriter's Laboratories Approved, Factory Mutual Approved, South Florida Approved insulation assembly. Celcore Cellular Concrete can be poured over some existing roof membranes in reroofing applications, galvanized steel deck form, precast concrete, or poured-in-place structural concrete. Celcore monolithic insulating concrete roof deck fills placed over metal deck form can be designed into structures as shear diaphragms. These composite systems provide good resistance to shear forces which may result from wind or seismic activity. Shear diaphragms provide bracing to the structures they cover acting to transfer and distribute an acting load force through-out the structure. Composition and Materials: Celcore Foam Concentrate contains no synthetic surfactants. It is comprised of natural saponified rosins and is protein stabilized. Celcore Foam Concentrate is non-corrosive, non-hazardous and readily biodegradable. It is packaged in (5) gallon [18.93 L] pails and displays the UL and FMRC mark on the product label.

CCC shall not be applied when raining. -END OF SECTION- CELCORE PVA SPECIFICATION 2

23 CELCORE THIN PATCH DATA/SPECIFICATION PART 1: GENERAL THINPATCH is a non-hazardous, non-corrosive additive to Portland cement mixes. It was developed to prevent rapid drying of concrete mixtures used to make repairs or detail cementitious roof decks. Rapid drying can cause powdering, chalking and/or severe cracking of non-modified mixtures. Additionally, THINPATCH is added to ensure adequate bond to the parent surface and to lower the modules of elasticity in high cement factor concrete mixtures. Accordingly, the brittleness of the repair material is reduced, lessening the possibility of fragmentation which could damage the roof membrane by puncture. THINPATCH also serves as a plasticizer which will allow mixing water reductions of 10% to 15% over corresponding mixes without its use. In situations where THINPATCH is used to cap or repair roofing substrates, its use should be communicated to the roof membrane manufacturer. Although THINPATCH has been tested by several roofing manufactures for BOND and UPLIFT resistance, there may be special conditions that the roof membrane manufacturer may want to confirm by test or verbally with CELCORE Inc. PART 2: MATERIALS: THINPATCH is produced by CELCORE, Inc., of Black Mountain, North Carolina. Containers of THINPATCH shall be clearly identifiable by labeling. The admixture is a free flowing, redispersible powder which shall be kept in dry storage to avoid caking. PORTLAND CEMENT used may be of various brands, however, the Types must be identified as either I, II, or III, and labeled as meeting the requirements of ASTM C-150. WATER for mixing shall be lean, fresh, and free from injurious quantities of acid, alkali, salt, oil, organic matter or other impurities. Installation in cold weather may require the use of heated water. AGGREGATES, if utilized, may be conventional concrete aggregates (limited however to fines) meeting the requirements of ASTM C-33, perlite lightweight aggregate meeting the requirements of ASTM C-322, Group 1, or preformed foam for cellular concrete, meeting the requirements of ASTM C-796. The use of vermiculite aggregate is not approved. PART 3: MIXES: Where minimum thickness of 1/8 in. [.32 cm] or less are required for surface smoothing, THINPATCH modified neat cement slurry mixtures are recommended. These THINPATCH modified cement paste mixtures may be applied by troweling, squeegee, or other method resulting in the desired smoothness of the finished surface. The THINPATCH mixture for this type of application shall be formulated as follows: Cement: 94 lbs [42.64 kg] 1 sack Water: 56 lbs [25.4 kg] 6.7 gal [22.36 L] THINPATCH: 3 lbs [1.36 kg] After mixing the above ingredients thoroughly, allow the mixture to stand idle for about 10 minutes to allow adequate wetting of the cement, then re-mix to assure uniform dispersion. Begin application of the mixture immediately. Where repair thickness greater than 1/8 in. [.32 cm] but less than 3/4 in. [1.09 cm] are required, an aggregate filler is recommended. For nailable decks use perlite concrete aggregate. For non-nailable decks use concrete or masonry fine aggregates. Depending on strengths required, mixes of 1 part cement to 2 parts or 3 parts aggregate may be used. THINPATCH additive shall be used at the rate of 3 lbs [1.36 kg] per bag of cement. Aggregate gradations shall be chosen to fit the thickness of the fill required. Water content shall be sufficiently high to allow an easy flow for placing. CELCORE THIN PATCH SPECIFICATION 1

24 Where thicknesses greater than 3/4 in [1.09 cm] are required cellular or perlite concrete is recommended. Perlite mixes shall not have a cement factor of less than 1 part cement to 6 parts perlite with 6 lbs [ 2.72 kg] of THINPATCH per cubic yard. Cellular concrete mixes shall be designed to 40 lbs/ft3 [64 kgs/m3] cast density. Water content shall be sufficiently high to allow an easy flow for placing. PART 4: PREPARATION: Before the application of the selected THINPATCH mixture, the surface must be thoroughly cleaned of loose debris. The preferred method of deck preparation shall be by sweeping, vacuuming or blowing. Deck surfaces may be moistened to receive thin applications particularly in hot weather. A covering of standing water shall not be permitted however. Any portion of the existing deck determined to be unbonded to the structural substrate or otherwise unsound shall be pointed out to the architect/contractor/owner for proper corrective action. PART 5: PLACING: The crew installing the THINPATCH mix must be of sufficient size to handle the volume of the batches. Placement time for any size batch should not exceed one hour. in no case shall batches be retempered with water after the placing operation has commenced. Materials which have exceeded the time limitation or have lost desired workability shall not be used in the application. With the exception of applications having thickness of less than 1/8 in. [.32 cm], screeds should be set when capping to provide a uniform and true surface. CELCORE THIN PATCH SPECIFICATION 2
