B. Project conditions involve only inspection and preparation of the substrate surface to be coated.

C. Environmental Conditions

1. All materials individually or mixed shall have zero volatile organic content (VOC).

2. Do not apply materials if rain is anticipated within three hours of application.

3. Substrate and air temperatures must remain above 40ºF for at least four hours after application of materials and remain above freezing for 24 hours.

4. All materials are non-hazardous and Class A fire rated.

1.07

GUARANTEE

A. The certified applicator shall provide the owner with a five-year guarantee on the labor and the manufacturer shall provide a five-year guarantee for the products covered by this specification.

1.08

MAINTENANCE

A. Wash traffic deck membrane with soap and water using a bristle brush or pressure washer of 1000 psi. Periodic cleaning extends the life of the membrane and enhances its appearance.

B. Chemical spills must be removed to avoid possible damage.

PART 2 - PRODUCTS

2.01

MATERIALS

A. SC-113 VEHICULAR TRAFFIC SYSTEM WITH CORROGARD MCI

Three coat 135 mil (minimum) traffic-bearing membrane overlays, EM-100 P over cracks and flashings, and the substrate. No substitutions.

B. MANUFACTURER: Strongwall Industries, Inc. as provided by: Shield Systems, Inc. 5205 Bischoff Avenue, St. Louis, MO 63110 Office: 314-865-5550 Fax: 314-865-5556

2.02

COMPONENTS

A. Traffic-bearing component is a latex vinyl copolymer emulsion and a factory apportioned catalyst with abrasion resistant aggregates and Corrogard MCI (Migratory Corrosion Inhibitors).

B. Crack treatment is an elastomeric polyurethane and epoxy system component membrane with sand broadcast.

C. Cleaning agent is water or solvent depending on product.

2.03

MIXES

A. Materials

1. Crack treatment component:

EM-100-P, a rubber emulsion, packaged in 5-gallon pails.

Mixing Ratio: Per manufacturers written instructions Yield: 40 sq. ft. at 40 mils wet.

2. Traffic-bearing component:

Strongcote SC#3 Liquid, a latex vinyl copolymer, 5 gallons of liquid packaged in a 6-gallon pail and Strongcote #3-HD (heavy duty) Powder, an aggregate catalyst, packaged in 55-pound bags includes Corrogard MCI (Migratory Corrosion Inhibitors).

Mixing Ratio: Two 55-lb bags of Strongcote #3 (HD) Powder and one 5-gallon pail of Strongcote #3 Liquid form one unit.

Average Yield Per Unit (on smooth concrete) SC-113: 350 SF per coat. @ 45 mils per coat Note: Yield dependent on substrate condition, temperature, method of application and other variables.

B. Mixing

1. Stir Strongcote #3 Liquid in its shipping container for about 30 seconds and pour one-half its contents into a clean mixing container.

2. Gradually add one bag Strongcote #3 HD Powder into the shipping container, mixing continuously as the powder is added, using a ½” -3/4” varispeed drill with mounted Jiffy blade or mortar mixer.

3. After all powder is added, continue to mix for 3 minutes until the materials form a lump-free mixture. The mixture has a pot life of 30 minutes at 70°F.

PART 3 - EXECUTION

3.01

ACCEPTABLE INSTALLERS SHALL BE TRAINED AND CERTIFIED BY THE MANUFACTURER

3.02

EXAMINATION

A. Concrete

1. Before the membrane is applied, inspect the top surface of the substrate, perform all required structural and surface repairs, profile to eliminate ponding and treat as necessary to remove laitance, loose material on the surface, grease, oil, paint and other contaminants, which will affect the bond of the membrane.

2. Verify that curing methods used for concrete are compatible with the top surface requirements for the traffic deck membrane.

3. Commencement of membrane installation implies acceptance of the top surface of the substrate area only, as suitable to accept deck-membrane system.

3.03

PREPARATION

A. Equipment Options

1. Shot blast existing surface in accordance with International Concrete Repair Institute (ICRI) Technical Guideline No. 310-2. Concrete Surface Profile (CSP) after shot blasting should be CSP-3 to CSP-5. Ensure all oil, grease and other contaminants are removed prior to placement of ramp coating.

3.04

APPLICATION

A. Vehicular and Heavy-Duty Vehicular Traffic Membrane: Strongcote SC-113

1. Crack treatment component

a. Detail all cracks and cracks wider than 1/16” minimum to 3/8” maximum and fill with EM-100 P sealant, per manufacturer’s recommendations and details. Apply over all cracks, a 3" wide (minimum) ribbon of EM-100-P epoxy primer and allow to dry 2-4 hours. Spread at 150 SF per gallon. Next mix and apply EM-100P elastomeric rubber component in one 40 wet mil coat at 40 SF per gallon 3” wide. Broadcast clean, 10-20 sand over coating when coating becomes thumb print tacky. Upon cure remove excess sand and apply EM-100P epoxy primer at 150 SF per gallon. Allow to cure.

b. Refer to project details for more information.

2. Traffic bearing component

a. Dampen concrete surfaces to a dull grey with no standing water prior to applying SC-113.

b. Mix and apply three consecutive coats in the specified thickness over the entire surface by squeegee and then provide broom finish for texture. Control thickness by covering a measured section with each unit. Allow to cure for 2 hours (minimum) before reapplying.

c. Allow to cure for 24 hours (minimum) before opening to traffic.
