PART 3 - EXECUTION

3.01 INSPECTION

  1. General
    1. Concrete surface shall be free of excess roughness, voids, protrusions, loose particles, dust or debris. Poorly finished concrete may telegraph through the Excel-Coat K/D (or K/D II) System.
    2. Concrete surface must be free from curing agents, bond-breakers, hardeners, oils, grease or foreign matter that may affect the adhesion of the Excel-Coat K/D (or K/D II) System.
    3. Concrete substrate shall be designed and constructed as to freely drain and eliminate the ponding of water. Slope: 1/4" per foot.
    4. Concrete moisture content shall not exceed 10%. Moisture Vapor Transmission shall not exceed 5 lbs. per 1,000 square feet per 24 hours.
  2. New Concrete
    1. Curing of concrete shall be by means of water-cure or dissipating compounds. Curing compounds to be used shall be approved by an authorized representative of Excellent Coatings International.
    2. Concrete shall be cured a minimum of 28 days prior to installation of Excel-Coat K/D (or K/D II) System.
    3. Concrete shall be finished with a power metal float followed by a light steel trowel and fine-medium hair broom or equivalent.
    4. Concrete moisture content shall not exceed 10%. Moisture Vapor Transmission shall not exceed 5 lbs. per 1,000 square feet per 24 hours.
  3. Old Concrete
    1. The following are effective means of cleaning and preparing old concrete prior to the application of Excel-Coat K/D (or K/D II ):
    2. Surface Grinding: A heavy duty, industrial grinder may be used to clean and abrade the concrete when the surface is dry. Loose particles and dust must then be removed by vacuum or blower.
    3. Shot Blasting and Sand Blasting: These are both effective means of cleaning concrete surfaces. Before coating, area must be free from dust or any loose particles.
    4. Acid Etching: A solution of commercial muriatic acid and water (3 parts water: 1 part muriatic acid) is also a satisfactory method of cleaning concrete. Pour solution over concrete surface and agitate with stiff bristle broom or brush. The solution will react with the concrete causing it to bubble. Once the bubbling has stopped, power wash the deck with water to rinse away residual salts and contaminants. To ensure complete neutralization of the concrete surface, the deck may be brushed with alkali solution (1% ammonia in water) and then rinsed.
    5. Commercial Detergents: Commercial detergents, such as Trisodium Phosphate (TSP), will work well to clean light grease and grime, but these products are not recommended for heavy contamination.
  4. Concrete Patching
    1. Repairs to old or new concrete may be necessary to correct minor imperfections in the surface (i.e. low spots, holes, ridges and protrusions).
    2. All repair areas shall be cleaned as described above, then filled with Excel-Crete Patching and Sloping Compound for repairs less than 1/8 inch in thickness. Refer to Excel-Crete Data Sheet for repairs that are greater than 1/8 inch in thickness. Excel-Crete repairs shall cure for a minimum of 24 hours prior to Excel-Coat K/D (or K/D II) system application.
    3. Small spalled areas may be repaired with a two-part semi-rigid epoxy.
  5. Expansion Joints & Cracks
    1. Expansion joints shall be cleaned thoroughly and sealed with urethane sealant.
    2. Cracks over 1/16"shall be routed, primed and repaired with an epoxy crack repair material.

3.02 INSTALLATION (Select Installation for appropriate system that is to be used. Selection shall correspond with 2.01)

    3. Mix texture coat and apply using a hopper. To create a knock-down finish, follow the texture application with a steel finishing trowel. Careful and consistent measuring of products helps to ensure color uniformity. Excel-Crete Retarder may be added to mix to prolong workability of product in the hopper. For best results, allow the texture to begin to dry (1-15 minutes) before knocking down with trowel. Allow 24 hours to dry.
