Confirm that the concrete substrate is in full compliance with Federal, State, local standards, building codes, project plans and specifications, prior to installation of AlertTile panel.
Installation surface area must be cleaned of debris, dust, oil, grease and concrete laitance, making sure the area is completely free of surface moisture. It’s recommended to use a diamond cup grinder, pressure shot-blaster or (at a minimum) use a wire brush to remove any dirt or foreign material.
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)
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 ¾” from the edge following the scored perimeter and center cross pattern. (Figure 2)
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)
Begin in the middle, then work your way towards the edges, inserting anchors and #14 stainless screws into the pre-formed countersunk fastener locations. Using a #3 square head bit, apply downward pressure with screw gun, press 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)
Following panel installation, caulk around the perimeter of the panel with NP1 or equivalent. Blend and taper the caulking smooth around the perimeter in a cove profile between tile and adjacent concrete substrate. (Figure 6)
Always wear protective gloves/protective clothing/eye protection/face protection.
