Edge Finish Carpet
Just place a bead along the edge where it is fraying.
Edge finish carpet. Pull the edge of the carpet back 1 to 2 feet so you can see the underlying subfloor which may be concrete or plywood. Place your carpet face down on your work surface. Staple along the edge. Start from the back side applying the tape where the carpet edge meets the finishing raw carpet edges.
Check straightness of the remnant edge with the measuring tape and marker marking on the back side of the rug any areas that need to be trimmed with scissors. This is done by a carpet binding machine. Step 3 measure the width of the doorway using a tape measure and then cut a carpet tack strip to the same width using tin snips. Binding the edge of a carpet involves wrapping a strip of fabric which is generally made from either polyester or cotton around the edge of the carpet and stitching it in place.
Place the cloth along the edge on top of the pile so the edge of the pile and the edge of the cloth are together. Cut any protruding edges straight or to the shape you want your rug. The stuff mentioned above is for fabric the fray check and stop thread i don t think it will hold up if it gets wet. Set your carpet down pile up.
Vacuum the subfloor to remove all dirt and grit. If you are using the staple gun plate idea you would put your metal plate under the carpet and staple down the edge. One of the methods that you can use to finish off the edge of a piece of carpet is to simply attach it to a tack strip. I would say glue hot glue or a marine glue.
