    1. PART 3 EXECUTION
    1. INSPECTION
      1. Verify surfaces and cracks to be treated and coated, are dry, clean, and free of efflorescence, oil, or other matter before beginning the treatment of cracks and application of coating to the surface.
  • Beginning of installation means acceptance of substrate.
      1. PREPARATION
      1. Remove loose particles and foreign matter.
  • Remove oil or foreign substance with a cleaner that will not affect coating.
  • Protect adjacent surfaces not scheduled to receive coating.
  • Cracks of 1/8" or greater, or that contain spalled areas or are fragmented in structural sections within the crack shall be opened by routing or other means. The crack is then, to be moistened with water. The crack is then, to be filled with a BOND&SEAL 40% and silica sand mix to a level flush with the top of the substrate.
  • Areas containing cracks of less than 1/8 in., shall be treated with silica sand (blend of 30 and 60), by sprinkling and brushing it into the cracks. This is, immediately followed by a light watering, to ensure compaction of the sand into the cracks. This should be repeated, 2 to 3 times or until such time the silica is level with the substrate’s top surface.

    • F.? Excessive surface sand should be removed by an air blower or other effective means.

      1. FIELD QUALITY CONTROL
      1. Field inspection and testing will be performed.
  • Manufacturer of water repellant coating shall provide the inspection services as required.

    •  

      1. APPLICATION
      1. Delay work until top of substrate is dry to touch but sanded cracks are still damp.
  • Apply coating in one liberal flood application and using an industrial foam squeegee to move material into silica filled cracks to ensure complete saturation and to remove excess material. Application should commence from highest point to the lowest point.
  • For a finished non-skid surface, silica sand should be, lightly and evenly, broadcast on to the first coat, with a second coat of the coating being, immediately applied over the sand for increased adhesion.
      1. PROTECTION AND CLEANING
      1. Protect adjacent surfaces from damages and stains.
  • Clean materials from surfaces where inadvertently applied.
  • Protect finished installation.
