How to Replace Carpet Aluminum Edging on a Slab

Remove the Old Aluminum Edging

• 1

  Look at the top of the aluminum strip to identify if concrete screws hold it to the subfloor. Turn each screw counterclockwise using a power drill to detach them. If you don’t see any screws, the strip is held to the subfloor using only adhesive.

• 2

  Insert the wedge-shaped end of a pry bar under the metal strip. If needed, tap the end of the pry bar with a hammer to slide it under the edge. Push the handle of the pry bar toward the floor to pry up the strip.

• 3

  Locate the wooden carpet tack strip along the edge of the carpet and pry it up from the floor as well.

• 4

  Place a chisel on the concrete subfloor and tap it gently with a hammer to dislodge any chunks of adhesive that remain attached.

• 5

  Vacuum the area thoroughly to remove all adhesive and dirt before you apply the new aluminum strip.

Install the New Aluminum Edging

• 6

  Measure the width of the old aluminum carpet edging to determine the proper width for the new one. Measure the proper length on the new strip and mark it with a marker. Then repeat the measuring process on the rubber molding that attaches to the underside of the strip.

• 7

  Cut the rubber molding along the marker line using tin snips and cut the metal part using a circular saw. Always wear safety glasses when using the saw.

• 8

  Turn the metal portion upside down and align the rubber portion on the back in the center track. Push the rubber molding in place until it is secure.

• 9

  Install a tube of construction adhesive in a caulk gun, snipping 1/4-inch off the nozzle with scissors.

• 10

  Apply a 1/4- to 1/2-inch-wide bead of adhesive along the entire width of the floor, directly on top of the exposed concrete.

• 11

  Cut a new carpet tack strip to the width of the opening and cut it using the tin snips. Install it on the concrete floor as close as possible to the carpet. Press the carpet into the upper spikes to hold it in place.

• 12

  Turn the new aluminum strip so the rubber faces downward and press it into the construction adhesive.

• 13

  Apply painter’s tape over the aluminum strip every 4 to 5 inches to hold it down while the adhesive dries. Remove the tape after 24 hours.
