Really the only time your going to have to make a carpet seam is when you’re piecing together one or more pieces of carpet, which usually happens in your bigger rooms. The other major thing that you need to remember about a carpet seam, is you need to do it right the first time or the carpet will have to be replaced as you can’t redo the seam. There are a few steps to insure that you get it right the first time, so you do not run into this sort of problem as it can become quite expensive.
You will need to have a carpet knife, some seam tape, a seam iron, as well as a straight edge which is optional but is good to have on hand just in case. The first thing you will do is overlap the two pieces of carpet that you want to seam together. By overlapping them, you can make a clean cut the first time and not have to trim down later. Once you have them overlapping, cut the two pieces of carpet so that they will meet evenly and you have no gaps that can be seen. An alternative way to cutting your carpet this way is turn them upside down, this way the tuft of the carpet will not block any view you will need.
Now that you have the two pieces of carpet cut, you will use your seam tape and tape the two pieces together. You will want to make sure that you have your carpet taped tightly and securely, and also on the bottom of the carpet so that later when your seaming the pieces, they won’t come apart. Now that you have this down you will heat the seam iron to a temperature that is specified on the tape.
Now that you have the tape in place as well as your iron heated, run your iron over the taped seam so that you can activate the tape. You will want to move your iron at a slow even pace to make sure that not only is your tape is activated and being pieced to the carpet pieces, but also to make sure that your are getting the adhesive activated all the way across.
You have just done your basic carpet seam. It is quite easy to do it just takes patience and time. Now that you’ve done your first seam your next carpet seams should go quite easier. Remember to take your time and make sure you get it right the first time so you won’t have to replace more carpet than is necessary.
