Try to farm the replacement carpet from an inconspicuous area, such as inside a closet or underneath a bed. Be sure that the place you farm the replacement carpet from isn’t going to be visible. You can also keep extra carpet in your attic or storage for repairing damaged areas.
If working with a carpet cutting tool, use the tool to first make an imprint. Once an imprint has been made, attach the cutter blades and the pivot screw and make your incision, rotating as many as two or three times in order to remove it. [4] X Research source
Make sure that the adhesive disk is significantly larger than replacement patch: you want the disk to hold onto all of the replacement patch, especially the corners, as well as some surrounding carpet. When the patch becomes sticky again, in about three to five minutes, press down on the outer edge of the carpet to secure it into place.
Align the patch so that the direction of the fibers in the patch match the direction of the fibers in the rest of the carpet. You have about 15 minutes to position and align the patch perfectly before the glue sets, permanently anchoring your patch in place. Work quickly.
You can also vacuum the section with an agitator attachment to lift up the pile.
Rectangular patches can be cut using a utility knife, while circular patches can be cut using a circular carpet cutter.
You may want to save the damaged section in case you need to patch a smaller area that can be cut from this section.
You should hear a light sizzle when you touch the iron onto the patch pad. This is the water reacting to the heat, not the carpet burning. If the patch is big, go over different spots the patch with the iron — enough to cover the entire patch. You don’t want to fail to activate the head beneath the patch.
