Repair any damaged stair area. Remove any projections or obstructions. Remove loose dirt and debris.
NOTE: SURFACE MUST BE FLAT!
Tread ends, risers, and/or stringers are to be repainted, it is advisable to paint the surface prior to installing the BOLD STEP Safety Treads for this method of installation. Place all tools, materials and treads for installing on the bottom landing of the flight to be installed.
Begin with the top stair or landing and work down. If clearance has been allowed at the ends of the treads, center one BOLD STEP 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 guideline will be centered.
Push the BOLDSTEP Safety Tread back as far as it will go and place the top landing tread or treads in the proper location. Using the tread as a hole location template, carefully punch the location of each attachment hole.
Using the hammer drill, drill each hole 1/4” deeper than the length of the screws. Remove the dust created with the portable vacuum.
Lay 1/4” bead of construction adhesive on the underside on the underside of the tread being installed in a pattern similar to the illustration.
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.
Be sure that there is a consistent bead completely around the perimeter of the tread and around each screw hole to keep moisture from getting under the tread.
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.
