Gluing Carpet Seams

    Unroll The Carpet

    Take the two pieces that are going to be joined and lay them out side by side, so that they overlap by about three inches. Make sure that the pile is facing the same direction in each. If you are unsure, check the back, as it often contains arrows indicating the direction of the pile. If necessary adjust it so that the pieces are straight and even all the way up and down.

    Cutting a Straight Edge

    Roll back the carpet that is on top, and measure one inch in from its outer edge. Mark this with a shop pencil at twelve-inch intervals down its length. Then snap a chalk line across these marks to create a tracer. Next place a piece of scrap carpet underneath the rolled back edge, between it and the face of the carpet to protect it from your blade.

    Lay a straight edge along the chalk line that you created, then take a fresh carpet blade and slice it through the material along the guide. Be sure...MORE to cut down a single line of threads as you work. This is done to create a perfectly precise edge through the entire length of the carpet, removing any fraying pieces that may exist in its regularly manufactured condition.

    Cutting The Second Piece

    Now you want to lay the precise cut edge of the carpet back down over the uncut piece. It should still overlap the bottom piece by about one inch. Place a straight edge along the top cut line of carpet, and then use your sharp carpet blade to slice through the bottom carpeting material. As you work to make sure that you slice through a single row of threads. This will create a line that will perfectly match the edge of the first cut piece.

    Carpet Seaming Tape

    Center a line of carpet seaming tape underneath the two cut edges of the two pieces of carpet. Lay the tape out along the entire length, with the two pieces of carpet perfectly lined against one another. Using a single piece for the entire seam will help to make the join between the carpet pieces tighter.

    Heating The Carpet Seaming Tape

    Depending on the type of tape you use, you might need to heat it for several minutes in order to activate it. Heating is accomplished by applying an electric iron to its surface. This iron is embedded between the two pieces of carpet, with a thin handle stretching out between them so that you can operate it along the length of the seam. You should follow all manufacturer’s instructions concerning the amount of time the tape needs to be heated.

    Joining The Seams

    Move the iron slowly and steadily down the seams across the tape, allowing it to linger long enough to activate the adhesive at each point. As the iron passes on, press the carpet pieces behind it gently down into the tape, and together against one another. Place heavy objects such as tiles, large books, or pieces of wood on top of this seam to hold the carpet in place until the adhesive has a chance to dry.

    Completing The Seam

    Continue moving the iron steadily until you reach the end. When you are done, carefully run a rolling pin along the seam, removing, and then replacing the heavy objects as you run down the line. The weight of these items should then be left on the seam for another 15 minutes before they are removed completely. The final result should be a carpet surface that appears nearly unbroken, with the bristle of the threads hiding the precision of the cut between them.
