TOOLS REQUIRED

• Electric or cordless drill/driver 
• chalk line
• hammer
• tap handle
• taps & punch
• caulking gun
• drill bits
  

MATERIALS REQUIRED

• Step and landing treads
• adhesive
• stainless steel machine screws

PREPARATION
Repair any damaged stair area. Remove any projections or obstructions. Remove loose dirt and debris. NOTE: SURFACE MUST BE FLAT!

If tread ends, risers, and/or stringers are to be repainted, it advisable to paint the surface prior to installing the BOLDSTEP Safety Treads.

Place all tools, materials and treads for installing on the bottom landing, of the flight to be installed.

INSTALLATION
Begin with the top stair or landing and work down.

• If clearance has been allowed at the ends of the treads, center one BOLDSTEP Safety Tread on the top stair and one on the bottom step. Strike the chalk line on one edge of the treads from the top and bottom tread to create your guide on all steps. All treads, when placed along the guide line will be centered.
  
  
• Push the BOLDSTEP Safety Tread back as far as it will go, place the top landing tread or treads in the proper location. Using the tread as a hole location template, carefully mark the location of each attachment holes.
  NOTE: Sometimes on diamond plate, this center location will be on a sloped side of the embossed metal, so punch the center locations deeply and accurately!
  
  
• Drill and tap the holes with the proper size drill bits and taps for the screw size being used.
  
  
• Lay 1/4” bead of construction adhesive on the underside of the tread being installed. Place the adhesive around each screw hole, the edges of the tread and in an up and down format across the bottom of the tread.
  
  
• If there is a large radius at the front nose of the existing tread, place one or two extra beads of caulk at the appropriate location.
  
  
• Screw the tread in place and install the rest of the treads in a similar fashion.
  
  
• If possible, allow the adhesive to cure for several hours before use.
