How to Splice Carpet | HomeSteady

Carpet in a house is rarely one single piece. More often it is made of several strips that are spliced together. When done properly the splice lines are invisible, creating the illusion of a solid carpet surface. Splicing two pieces of carpet is accomplished with the use of a seaming iron and seaming tape.
Both of these items are available at your local hardware store. If you have never spliced carpet before, practice on a few remnants first.
-
Line up the two pieces of carpet. If the edges are not perfectly straight, overlap one on top of the other slightly. Use a sharp knife to trim the edge of the lower piece, using the edge of the upper piece as a guide.
-
Lay a strip of hot-melt seaming tape under the seam created by the two pieces of carpet. The seam should run down the middle of the tape.
-
Turn on the seaming iron and give it time to heat.
-
Hold the sections of carpet open and press the iron against the tape at the beginning of the seam. Let it sit for 30 seconds.
-
Begin sliding the iron slowly forward, heating the tape as you go. Have a second person press the two pieces of carpet together into the hot tape behind the iron, creating as tight a joint as possible.
-
Continue ironing the tape and splicing the carpet until the seam is complete.
-
Sew the two halves together using a curved needle and fishing line if the splice is in a particularly high-traffic area. Keep the stitches as small as possible to prevent them from being noticed.
-
Roll a carpet tractor over the seam to blend the carpet from both sides together.
