There is a wide range of tapes, with many different uses. Most are self adhesive and pressure activated, but there also exist water activated tape, heat activated tapes and tapes with no adhesive at all.


Tapes

Insulating Tape

800px-Electrical-tape green-yellow.jpg
  • PVC
  • Electrical insulation
  • Available in various colours
  • Often misused
  • Often falls off years later, don't rely on tape alone for basic insulation
  • Easily torn
  • Peels off most surfaces cleanly
  • Writable
  • PVC tapes also exist that aren't intended for electrical insulation. These are generally not self extinguishing
  • White tape isn't uv resistant

Building Tape

  • Fairly tough, easy rip general purpose tape
  • Peelable
  • For bundling materials
  • Masking (but several times the price of paper masking tape)

Masking Tape

Masking tape 0049-7.jpg
  • Peelable low tack flexible crepe paper tape
  • Available in various widths
  • Easily removed if not left on too long.
  • Masking tapes have a day rating, from 1-60 days. Leave it in place longer and it can stick very firmly
  • Low cost masking tape is best removed within a day or 2
  • White spirit can remove tape residue
  • Blue painter's tape is less prone to paint bleeding under the edges than tan masking tape, and should be used for car paints & similar.
  • Outdoor duty masking tape also available
  • Used to reduce chipping of laminate edges during sawing. Apply tape across the cut line.
  • Masking woes & solutions
  • Modern masking tape was invented in 1925 for use when 2 tone painting vehicles, previous masks could damage the paintwork.

Masking Roll

  • Wide paper or polythene with peelable adhesive strip along one edge of one side
  • Used similarly to masking tape, but giving much wider protection.
  • Different widths available

Carpet Mask

Cellophane Tape

Cellophane tape 4440-2.jpg
  • Eg Sellotape, Scotch tape, etc
  • Very low cost, light duty, limited life
  • All the adhesive tape defects in one tape type:
    • low strength.
    • adhesive fails in time
    • adhesive fails if wet
    • adhesive creeps & fails if heated
    • adhesive not peelable
    • old adhesive permanently marks the workpiece
    • tape discolours
    • tape goes brittle in time
    • tape vulnerable to UV
    • tape often shreds during use
  • Sometimes useful to hold things temporarily while you fix them permanently.
  • Sometimes used as a temporary fix if nothing else is to hand
  • Cellulose tape with clear adhesive was invented in 1930, and proved an unexpected hit in the depression, with people using it to repair a wide range of items.


Duct Tape

Duct tape 4442-3.jpg
  • Tough cloth reinforced tape for most jobs
  • sometimes called duck tape
  • Tearable by hand
  • Waterproof
  • Not recommended for ducting, duct conditions cause premature failure
  • The rubber adhesive can tear or mark what its applied to when removed
  • Gorilla tape is a stickier heavier duty version of duct tape
  • Tests show duct tape kills 21% of warts
  • Most popular tape for kidnap, abduction, armed robbery etc
  • Reminding employees of that can be counterproductive

Gaffatape-3.jpg
  • As duct tape, but with a cleanly peelable synthetic rubber adhesive.
  • avoids marking after removal
  • Several times the price
  • widely used on stage sets

Foil Tape

Ali tape 3531-7.jpg
  • self adhesive aluminium tape
  • For ductwork & HVAC
  • Seals gaps between foil faced insulation sheets to restore the vapour barrier

Window Foil

  • Self adhesive aluminium tape around 1/4" wide
  • Conductive, applied to window glass, detects breakage
  • Mostly superceded by PIR and ultrasonic glass break detectors.
  • Window foil has a mix of advantages and disadvantages compared to its now more popular alternatives.

Self Amalgamating Tape

  • Tape sticks permanently to itself.
  • Temporary repairs to pipes & hoses
  • Used as an insulation tape substitute, especially where the tape must not fall off in time
  • Waterproof
  • UV proof
  • Insulating (electrically)
  • Stretch it during application to ensure it bonds together

Self fusing tape

Silicone based version of self amalgamating tape with greater resistance to liquids

Friction Tape

2 types exist...

Electrical friction tape

  • Rubberised cloth insulating tape with very poor adhesion
  • Slightly tacky on both sides.
  • Obsolete

Grip enhancing friction tape

  • Modern friction tape has an effective adhesive on one side only
  • Used to enhance grip on handles, especially of sports equipment

Wall Repair Tape

Wall repair tape 0049-6.jpg
  • Crack repair tape
  • Ultrathin cloth with tapered edge
  • Put it over the crack & paint. Very quick, & hardly noticeable
  • The painted tape has a non-smooth surface, so it soils faster than the surrounding flat smooth wall
  • Its therefore a bit of a bodge

Clear Waterproof Tape

Clear tape 0063-4.jpg
  • Repairs to plastic cracks.
  • To repair plastics, align the plastic very accurately and apply tape to both sides of the crack. This prevents the break flexing and separating. The broken edges need to be aligned perfectly for this to work effectively. If done correctly with a tough tape, there will be no extra flexibility at the crack, and good usability is restored.
  • Can be used as glass crack repair where the lost strength is acceptable, eg for some greenhouse glazing

Magic Tape

  • Clear matt tape for torn paper repair
  • clearer & longer lived than cellophane, doesn't stain paper

Paper Tape

Paper tape 4055-4.jpg
  • Use to reinforce wet plaster on plasterboard joints

  • Can be used with wallpaper paste

Gummed Paper Tape

  • Water activated, and sticks on drying
  • Not often used in DIY now
  • Formerly used as a peelable tape, the paper must be soaked to release the glue.

Corner Bead Tape

  • Flexible paper tape

Plasterboard Joint Tape

PB joint tape, fibreglass 5733-4.jpg
  • An open mesh tape applied to joints before filling.
  • glass fibre or plastic

  • Used for high pressure gas as well
  • White is used for water but not approved for gas
  • PTFE on yellow reels is approved for gas work
  • Yellow reel PTFE is thicker than white
  • PTFE is a relatively inert material, making it suitable for use with a wide range of chemicals.

Marine Grade Tapes

Various different tapes come under this heading, but all are designed to be reliable in a harsh environment, and equivalent marine products have much longer life on land than products designed for land use.

They also come with much higher price tags, but where durability and reliability are important, marine grade adhesives are an excellent choice. Don't be surprised to see price tags starting at tens of pounds per roll, rising to over £100.
