Treads for indoor stairs are manufactured from clear Douglas fir or hard-wood thatâs free of knots and has dense grain. Due to this, fastening the treads to stair stringers needs some preliminary work to assure the wood doesnât split up during installation and stays in tact for the life span of the stairway. Stair- materials is milled using a bull nose edge that minimizes tripping hazards. Typically, you slice the the treads to size using a table saw or circular saw thatâs outfitted using a complete saw blade. Installation progresses to the very best of the stairway and starts at the cheapest — stage.
Stack the cut treads close to the base of the stairway for comfort. Position a tread atop the set of stringers using the bull-nose edge. Fit the edge of the tread from the risers sections — of the stringers.
Create a reference mark in the edge of the tread where it aligns with all the middle of either riser.
Set up an electric drill or cordless drill using a 1/16-inch-diameter drill bit. Drill three pilot holes for nails throughout the very top of the tread at every stringer. Space the innermost and pilot holes 1 1/2 inch in the edges of the tread. Drill the middle pilot holes mid-way between the front and back edges.
Set the tread apart. Set up a tube of building adhesive in a gun. Apply a bead of adhesive across the very top of every stringer.
Reset the tread in place and align the reference marks. Fasten the tread to the stringers -penny finish nails in to each pilot hole using a complete hammer. Set the 16-inch-deep using the hammer as well as a nail set.
Repeat the actions to fasten the treads.
