Warm the tape with a hair dryer or heat gun.When the adhesive is warm it comes off easier.
oil
Nail varnish remover, turpentine or lighter fluid are all very good at removing this but make sure you open windows/ doors ect when cleaning with these.
To repair a torn carpet, gather some heat-activated carpet tape, a seam iron and a utility knife. Lift up the edges of the rip in the carpet, remove the old carpet tape, and apply a length of new carpet tape. Use the seam iron to activate the adhesive and mend the carpet tear.
Gum, sticky tape residue, or dried paint can be challenging to remove from a carpet.
It is not recommended to tape carpet on stairs. There is a double sided carpet tape available but, generally used on some floor installations. A couple hundred dollar investment can get a professional to install it correctly with power staples.
Double sided carpet tape works well for most indoor and outdoor applications. For instance, if a person wants to keep a floor mat or carpet from sliding around, an application of double sided carpet tape will help hold the mat or carpet in place.
You need to be a bit more specific. If you are talking about an adhesive type tape, (duct, binding, or strapping tape), there are several commercial solvents available that will remove any residual glue. (Goop, Goo Gone, etc) If you are referring to the thermoplastic seam tape designed to hold sections of carpet together then no there is no solvent that will dissolve the adhesive. A professional will try one (or more) of three methods to remove seam tape residue. 1) Heating the glue will bring it back to a liquid state you can then try to wick it into a soft cloth or series of paper towels 2)Cut out the section of carpet & replace it with a patch 3)With a razor knife scrape the glue carefully from the carpet fibers Note that all three of these methods carry risks to both you & the carpet you're working on. Unless you know what you're doing call a professional. You're much better off hiring someone to do a small repair rather than paying to replace an entire room of carpet
If you're laying a fully fitted carpet, neither. If however it is rug, then realistically, either will do, but there's no real guarantee of their effectiveness.
The double sided tape will keep the carpet down, but not for long. The best thing to use is to turn to the use of specialized carpet glue.
with tape measure
You can either remove your carpet and add a new one, or wash the carpet
when you join two pieces of carpet you have to join them with seam tape, and the heat from the seam iron melts the glue on the tape to hold the carpet together
