Installation Procedure: Flush-Fit

Step 1: Install the riser flush to the stair. Use stairnose & shim to determine where to start your flooring. Tongue side of flooring plank MUST face stairnose so stairnose can fit snugly onto tongue. Remove stairnose and glue the flooring plank & shim down. Remove padding 2” back from plank before you glue it down.

Step 2: Preparing the floor & molding as outlined is mandatory to achieve the required bonding strength.

  1. Use a damp cloth (water only) to clean both surfaces of loose particles or surface films.
  2. Turn stairnose over and roughen the inside surface of the stairnose to increase bond by means of 60 grit sandpaper, sanding sponge, or a metal brush.
  3. Roughen the area that will be covered by the stairnose with sandpaper (100-150 grit), sanding sponge or metal brush. Only roughen up area that will be covered (1.25” to 1.5”).
  4. Degrease both surfaces to remove all traces of oil, grease, dust, and fingerprints by using a light solvent such as isopropyl alcohol.
  5. Let both surfaces dry thoroughly before applying adhesive.

Step 3: Next, apply a generous serpentine bead of a Versatrim Molding Adhesive or PVC construction adhesive along the entire inside corner as shown below. Reveal edge of plank may show when stairnose is installed. To compensate, apply a little more adhesive to the molding.

Step 4: Touch the bottom of molding to the stair riser and carefully roll the stair nose in place. Make any final adjustments before you push the molding all the way down. Once it’s in the final position, press down firmly with your hands and make your way down the entire stair nose. It may take 2 or 3 passes to set it firmly in place.

Step 5: Allow at least 24 hours for the adhesive to form a bond. You should always start at top of stairs and work your way down to avoid contact with the installed moldings until cured.

Installation Procedure: Overlap for Floating Floors

Step 1: Install the riser flush to the stair. Cut a 1” wide strip of your floor. Drill, counter-sink, screw and glue it flush to the stair riser. Install flooring 0.375” from the glued down 1” strip.
DO NOT glue flooring down.

Step 2: Preparing the floor & molding as outlined is mandatory to achieve the required bonding strength.

  1. Use a damp cloth (water only) to clean both surfaces of loose particles or surface films.
  2. Turn stairnose over and roughen the inside surface of the stairnose to increase bond by means of 60 grit sandpaper, sanding sponge, or a metal brush.
  3. Roughen the area that will be covered by the stairnose with sandpaper (100-150 grit), sanding sponge or metal brush. Only roughen up area that will be covered (1.25” to 1.5”).
  4. Degrease both surfaces to remove all traces of oil, grease, dust, and fingerprints by using a light solvent such as methyl ethyl ketone (MEK), acetone, or isopropyl alcohol.
  5. Let both surfaces dry thoroughly before applying adhesive.

Step 3: Next, apply a generous serpentine bead of a Versatrim Molding Adhesive or PVC construction adhesive along the entire inside corner as shown below. Be sure to NOT put adhesive toward the front of the molding.

Step 4: Touch the bottom of molding to the stair riser and carefully roll the stair nose in place. Make any final adjustments before you push the molding all the way down. Once it’s in the final position, press down firmly with your hands and make your way down the entire stair nose. It may take 2 or 3 passes to set it firmly in place.

Step 5: Let the adhesive cure for at least 4 hours before any walking on it. For exposure to full traffic, wait 24 to 48 hours.

Installation Procedure: Miter Cut for Stair Tread Return

IMPORTANT: Make sure to use safety goggles and thick gloves while using saw and handling the blade.

We recommend using a compound miter saw fitted with a carbide tipped cross blade (60 or 80 teeth, ATB) for cutting aluminum stairnose molding.

Use a 2×4 miter sample to see if your stair is a true 90 degree corner, as they often are not. Adjust your miter cut by increasing or decreasing your angle accordingly.

Step 1: MAKE TEST CUTS ON SCRAP 2×4

IMPORTANT: Make sure the bevel angle is set to ZERO (A).

We highly recommend you do a test cut on 2 scrap pieces of 2×4 to make sure your cuts line up. Set the miter angle to 45 degrees for the first cut (B). Cut the 2×4 (C).

Then change angle of miter cut to 45 degrees in the other direction (D). Cut the other piece of 2×4.

Line up ends of the 2x4s to form a corner (E). Check the pieces to see if they line up correctly with no gap on the top or front view (F).

Step 2: CUT YOUR STAIRNOSE

IMPORTANT: Use a scrap 2×4 piece to set stairnose on while you make the cuts (G). This will keep the stairnose level while you cut.

Set the miter angle to 45 degrees. Make your cut (H).

IMPORTANT: Hold the molding extremely tight, otherwise it will pull in the direction of the blade and your cut will be off.

Change miter angle to 45 degrees in the other direction (I). Again, make sure you hold the molding extremely tight. Don’t let it move while you make the cut. Cut the other piece of stairnose.

Check the 2 molding pieces to see if they line up correctly with no gap on the top or front view (J).

STEP 3 – APPLYING STAIRNOSE TO THE STAIRS

After wiping the stairnose clean from debris, turn the moldings over (K).

Line up the ends of the moldings to form a corner. Place a piece of painter’s tape between them to hold them together so you can test the fit (L).

Test the fit on your stairway. Make sure there is no gap between the moldings (M).

After you test the fit, run a thick line of Versatrim Molding Adhesive or PVC construction adhesive along the inside of each molding (N).

Put the molding in place, pressing down firmly to make sure it is in contact with the floor or stair tread (O).

Make sure the edge is square. While pressing both ends firmly together, stretch a piece of painter’s tape tightly across the corner edge to keep the moldings from separating while the adhesive cures (P). Let the adhesive cure for at least 4 hours before any walking on it. For exposure to full traffic, wait 24-48 hours.
