Installation Guide
Installation Instructions and how to video available at Stairtek.com 
Tools Needed for Installation: 
• Table Saw 
• Circular Saw 
• Hand Saw 
• Level 
• Square 
• Bevel Square 
• Caulk Gun 
• Hammer 
• Chisel 
• Eye Protection 
• Ear Protection 
•  Polyurethane based construction adhesive (PL2000 or similar). 
Preparing the Existing Treads for Covering: 
•  Remove all the carpet and padding, making sure you remove all the nails, staples and tacking 
strip. 
•  Use circular saw to trim the front nose of the tread. Cut the nose flush with the face of the riser 
below it. Wearing your safety glasses, make sure the blade is set to the depth of the tread that 
you are cutting off. 
•  Due to the circular saw not being able to cut the entire overhang of the nosing off carefully cut the 
remaining nosing off at both ends with a hand saw and remove it. Cut carefully to avoid 
scratching the stringer. 
•  Clean up the front edge of the tread with your chisel, as needed. It is important to have a square 
surface. 
Checking the Stairs’ Safety Before Installing: 
•  Cut a small piece off the ends of both the riser and tread and set them in place. 
•  Mark the intersection where the tread meets the stringer. 
•  Measure the distance your pencil line is from the top of the stringer. 
•  Mark the balance of the treads by measuring down from the top of the stringer to ensure that 
each is equal distance to the top of the stringer (This ensures the safety of the new stairs when 
they are in use and that the front edge of all treads have the same overhang). 
Installing the First Riser – Start at the bottom where the riser meets the floor and work up 
•  Check that the intersection of the riser and the existing stringer is square.  
•  Right Side. Use the bevel square to ensure you get a tight fit. Slide the bevel square into the 
right corner and swivel the arm tight against the stringer then tighten the wing nut to keep the 
angle. 
•  Transfer the angle with the bevel square to the new riser. 
• Cut the right end of the riser with the table saw. 
•  Measure the distance the new riser is across. You will need the distance so that you can transfer 
it to the material. Before transferring the distance to the material, please note two points: One, the 
initial cut you made on the end of the riser is not square; therefore, there is a top and bottom to 
the new riser. Two, make sure you measure from the new cut to the uncut end of the riser to 
ensure a tight fit.
