  2. The Vitrified Polymer Composite (VPC) Surface Applied Detectable Guidance Tiles specified is based on Armor-Tile manufactured by Engineered Plastics Inc. (800-682-2525).

 

 

  1. MATERIALS
  1. Heavy duty elastomeric polyurethane adhesive as manufactured by Boiardi, Mapei, Bostik or approved equal.
  2. Heavy duty elastomeric polyurethane sealant as manufactured by Boiardi, Mapei, Bostik or approved equal.

 

PART 3 EXECUTION

 
  1. INSTALLATION
  1. During all surface preparation and tile installation procedures ensure adequate safety guidelines are in place and that they are in accordance with the applicable industry and government standards.
  2. The application of all adhesives and sealants shall be in strict accordance with the guidelines set by their respective manufacturers.
  3. Throughout the installation phases of surface preparation and tile setting, ensure that care is taken to prevent damage to any work.
  4. Lay out area to receive tile and mark with an indelible felt pen a reference grid for the tile to be laid.
  5. Set the diamond bladed double headed wet saw to the appropriate depth of 1 ½ " x ¼" wide to achieve the necessary parallel grooves in the area to receive the Detectable Guidance Tile.
  6. After saw cutting has been completed, the surface is to be vacuumed and power washed with clean clear water, free from all dirt and debris. Visually inspect all surfaces for obtrusions or foreign matter. If obtrusions are present, promptly grind away.
  7. Immediately prior to installing the surface applied Detectable Guidance Tiles, all surfaces must be inspected to ensure that they are clean, dry, free of voids, curing compounds, projections, loose material, dust, oils, grease, sealers and determined to be structurally sound before the application of the setting adhesive. The setting adhesive requires that the substrate and the ambient temperature are 40 degrees F minimum.
  8. Spread the adhesive to provide complete coverage in the grooves and over the surface, using a clean, well-maintained ¼ " x ¼ " V notch trowel.
  9. Inspect the tile and clean with acetone all dust and other contaminants from the surfaces to be adhered, then set the tile in place, true and square
  10. All subsequent tiles are set following the same procedures as outlined in H and I. A gap of 3/16" allowed between tiles for expansion and contraction is mandatory.
  11. Following the installation of the tiles, the urethane sealant system color matched to the adjacent surface should be applied to the joint between abutting tiles and between tiles and adjacent surface. Follow the manufacturer’s recommendations when mixing or applying the sealant system and ensure that the joint is clean and free of debris, and any excess adhesive is cut away to provide sufficient depth for the sealant in the saw cut in accordance with the contract drawings.
  12. After the area has been fully tiled and sealant system applied, the tile surface shall be cleaned, following the recommended maintenance and cleaning procedures.

  1. CLEANING AND PROTECTING
  1. Protect tiles against damage during construction period to comply with guidance tile manufacturer’s specification.
  2. Clean guidance tiles not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean tile by the method specified by the manufacturer.
