2. The application of all adhesives, sealants and mechanical fasteners 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 line for the saw cut to be made.
5. Make saw cut in existing substrate straight and true. Ensure all dimensions and tolerances are as shown on the contract drawing. The saw cut at the leading edge of the installed tile is to be approximately ¼" wide x ¾" deep and 2’0" from the platform edge. A trial of the saw cut approximately 10’ long shall be done on each platform to allow for checking to the contract drawing and fitting two tiles confirming tolerances are maintained.
6. After the saw cut is made, the surface between saw cut and platform edge is ready for planing. Setting the diamond head planer to the appropriate depth, plane approximately 10 feet of platform edge. Use two of the tactile tiles shipped as a template to check all tolerances are within that of the contract drawing. Make necessary adjustments and continue to plane platform edge ensuring planing is straight and true and the depth of the cut is within tolerances.
7. After planing has been completed, the surface is to be vacuumed and flushed with clean clear water, free from all dirt and debris. Visually inspect all surface and saw cut for obtrusions or foreign matter. If obtrusions are present, promptly grind away, making sure saw cut is not chipped or damaged.
8. Immediately prior to installing the surface applied tactile 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 degree F minimum.
9. Spread the adhesive to provide complete coverage over the planed concrete surface and platform edge, using a clean, well-maintained ¼" x ¼" V notch trowel. The adhesive is also to be applied to the leading edge saw cut to a depth of ½" for proper tile embedment.
10. 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 to the platform edge. Drill holes true and straight to the depth required using the recommended bit with holes located by the molded recesses provided in the tile. Clean dust from the holes to provide clear passage for the anchor.
11. Mechanically fasten tiles to the floor surface using a punch pin and hammer to set the stainless steel impact anchors provided. Ensure the fastener has been set to full depth, straight and true. Care should be taken when setting the fastener to avoid any inadvertent blows with the hammer to the tile surface.
12. The leading edge of the tile should be checked to ensure that the tolerance provided is in accordance with the contract drawings. Adjustment to the tiles leading edge is accomplished with a small shim driven into the leading edge saw cut to wedge the tile flange against the side walls of the groove and hold the tile to the desired elevation.
13. All subsequent tiles are set following the same procedures as outlined in I, J, K, and L. The gap of 1/8" allowed between tiles for expansion and contraction is mandatory.
14. Following the installation of the tiles and allowing the tile setting adhesive 12 hours for curing, the urethane sealant system color matched to the adjacent floor finish should be applied to the leading edge saw cut to finish the tile flush with the adjacent floor finish. 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.
15. After the platform edge has been fully tiled and sealant system applied, the tile surface shall be cleaned, following the recommended maintenance and cleaning procedures.

2. CLEANING AND PROTECTING

1. Protect panels against damage during construction period to comply with tactile panel manufacturer’s specification.
2. Protect panels against damage from rolling loads following installation by covering with plywood or hardwood.
3. Clean tactile panels not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean tactile panel by method specified by tactile panel manufacturer.
