The Polydeck 100 balcony/walking deck system is for light service and is a liquid applied, moisture cured, polyurethane waterproof system. The system utilizes an epoxy primer, one coat of an aromatic polyurethane basecoat, one intermediate coat of an aromatic polyurethane with aggregate, and one aliphatic polyurethane topcoat. The Polydeck 100 balcony/ walking deck system is a specialized application of elastomeric waterproof coatings designed to expand and contract with normal structural movements. The Polydeck 100 balcony/walking deck system can be applied to protect surfaces against spalling, freeze/thaw damage, and chemicals commonly encountered on these surfaces. Installed and maintained properly, the Polydeck 100 balcony/ walking deck system will ensure years of service.

Product Instructions
For complete information associated with the application of all Polycoat Products decking systems and products, refer to the General Guidelines and Technical Bulletin sections of the Polycoat Products catalog, which describes the products, surface preparation, job conditions, finishing details and other necessary information.

Phase 1: Check area of application to ensure that it conforms to the substrate requirements, as stated in the general guidelines section. Prime all joints, cracks, flashings with approved primers as specified below in Phase 2. Apply PC- 260 over all joints, cracks and flashing. Bridge joints, cracks, and flashings with 4' Straight Jacket Tape pushing it into the PC-260 with a trowel. Using PC-260 as a caulking compound will shorten the curing time appreciably over conventional polyurethane caulks. Over reinforcement tape, apply a stripe coat of PC-260 and taper it onto the adjacent surface. Allow the surface to cure for 1 to 2 hours.

Phase 2: Metal, concrete and existing plywood which has been cleaned and sanded should be primed with Polyprime 2180 at a rate of 1 gallon/300 sq. ft. (0.14 liters/m²). Apply using a brush or phenolic core roller. This will result in a 3 dry mils (76 microns) thick membrane. *Note: For rough or porous concrete, use Polyprime EBF-LV at an approximate rate of 1 gallon/200 sq. ft.(0.20 liters/m²); this rate may vary on the porosity of the substrate. Metal should only be primed with Polyprime 2180. Allow Polyprime to become tack free before proceeding to Phase 3.

Substrates other than new plywood are to be primed.
Phase 3: Apply PC-220 to the substrate at a rate of 2 gallons/ 100 sq. ft. (0.82 liters/m²). For best results, use a notched trowel or squeegee. A phenolic core roller may be used but extra care should be taken to prevent air bubbles. Spread mixed PC-220 evenly over the entire deck resulting in a 23 ± 2 dry mils (584 ± 51 microns) thick membrane. Allow PC-220 to cure before proceeding to Phase 4. Recoats must be done within 24 hours of cure.

Phase 4: Apply a second coat of PC-220 at a rate of p gallon/ 100 sq. ft. (0.31 liters/m²). Immediately broadcast washed, dry, rounded sand, 20 mesh (0.0331 in.; 0.841 mm), 6.5+ Moh's minimum hardness, at a rate of 20 lbs/100 sq. ft. or as required to achieve a slip-resistant finish, into the wet second coat, covering it completely. This coat will result in a 8 ± 2 dry mils (203 ± 51 microns) thick membrane, exclusive of aggregate. After allowing to cure, remove all loose aggregate. Recoats must be done within 24 hours of cure.

Phase 5: Apply desired color of Polyglaze 100 or Polyglaze AL-50 topcoat at a rate of 1 gallon/100 sq. ft. (0.41 liters/m²). For best results, use a phenolic core roller. This coat will result in an additional 11 ± 2 dry mils (279 ± 51 microns) thick membrane.

Optional Second Topcoat: A second coat of topcoat is required for a warranted system. Apply a second coat of desired color of Polyglaze 100 or Polyglaze AL-50 topcoat at a rate of p gallon/100 sq. ft. (0.31 liters/m²). For best results, use a phenolic core roller. This coat will result in an additional 7 ± 2 dry mils (178 ± 51 microns) thick membrane.
