If carpet tape is not doing the job you can also use carpet glue to hold the patch in position.
Can you fix a patch of carpet.
Apply some carpet adhesive onto the patch requiring floor.
Properly planned and executed.
A line or 2 of glue on the surface of the carpet pad will often be sufficient.
Orient the patch so the grain of the carpet runs the same direction as the installed carpet then.
If you re using carpet tape stick it onto the base floor as well.
Place your patch to fill the hole the way that the patch s fibers follow the direction of the rest carpeting fibers.
Use the utility knife to lift the edges of the seam or rip.
Because the donor area is filled in either with a piece of remnant carpet or is left unrepaired carpet patching is considered to be imperfect but a net overall improvement.
Remove the old carpet tape from under both sides of the seam or rip.
Apply carpet adhesive to the fabric and to the carpet edges that surround the hole you cut out.
If those fraying discoloring factors have concentrated in one particular section of your carpet you can patch the installation rather than replace the entire thing.
Tools and supplies you will need.
Hold the patch in place for a little while.
If the rip is small enough you might need to lengthen it with the utility knife.
