  • One-part BASF NP-1 Sealant / Adhesive (qty. 1)

Tools and Equipment Needed

  • One AlertTile® detectable warning panel
  • Hammer drill with 5/16” x 3″ concrete bit (or 8mm)
  • AlertTile® adhesive / sealant (BASF NP-1)
  • AlertTile® anchors
  • Caulking gun and sealant edging tool

  1. Confirm that the concrete substrate is in full compliance with Federal, State, local standards, building codes, project plans and specifications, prior to installation of the AlertTile® panel. Refer to the AlertTile® website for compliance documents.
  2. Installation surface area must be cleaned of debris, dust, oil, grease and concrete laitance, making sure the area is completely free of surface moisture. We recommend using a diamond cup grinder, pressure shot-blaster or (at a minimum) use of a wire brush to remove any dirt or foreign material. Note: Any application over newly poured concrete should have a minimum cure period of 30 days. 
  3. Lay out the panel on the concrete substrate and mark around the panel corners with a pencil to identify the designated installation location. (Figure 1) (not recommended or warranted for asphalt installations).
  4. Remove the panel from the marked installation area, flip over and apply a continuous bead of NP-1 adhesive to the back of the panel approximately 3/4″ from the edge following the scored perimeter and center cross pattern. (Figure 2)
  5. Place panel in marked installation area. Make necessary adjustment prior to fastening. Standing on the panel using a hammer drill with a 5/16″ carbide tipped bit, drill a hole a minimum of 2″ deep. (Figure 3) Clean drilling debris from holes. (Figure 4)
  6. Beginning in the middle and working your way towards the edges, insert anchors and #14 stainless screws into the pre-formed countersunk fastener locations. Using a #3 square head bit, apply downward pressure with a screw gun and press firmly until the anchor goes through the panel and is flush with the surface of the concrete substrate. Tighten the screw until the screw is in full contact with the countersunk fastener surface of the panel. (Figure 5) 
  7. Following panel installation, caulk around the perimeter of the panel with NP-1 or equivalent. Blend and taper the caulking smooth around the perimeter in a cove profile between the tile and adjacent substrate. (Figure 6)
