Self-adhesive cable clips have one failure mode, and it is nearly always the surface rather than the adhesive. A minute of preparation is the difference between years and a fortnight.
Clean the Surface
The step almost everyone skips. Adhesive bonds to what it touches, and what it usually touches is a thin film of dust, grease and furniture polish.
Wipe with isopropyl alcohol or a little methylated spirit and let it dry completely. Household cleaners frequently leave a residue that is worse than the dust.
On a desk or a skirting board that has been polished, this matters enormously, because silicone polish is specifically designed to stop things sticking.
Press and Wait
Adhesives reach full strength over time rather than immediately. Press firmly for thirty seconds, then leave it a day before loading it with a cable.
That single instruction resolves most of the failures people report, and packs sold in quantity, of the kind at eboot.net, make it easy to place several and let them all set together.
Surfaces That Work
- Painted wood and melamine, once cleaned
- Glass and glazed tile, which are ideal
- Smooth plastic, including most desks and monitor stands
- Metal, provided it is not oily
- Sealed skirting boards
Surfaces That Do Not
Textured wallpaper, which peels away from the wall taking the clip with it. Bare plaster, which crumbles. Anything dusty, silicone-treated or freshly painted.
New paint needs a proper curing period, usually several weeks, before anything is stuck to it. Adhesive on uncured paint pulls the paint off.
Temperature Matters
Most adhesives bond poorly in the cold and creep in the heat. Applying at normal room temperature works best.
A clip on a car dashboard in summer, or on a cold garage wall in winter, is working outside what the adhesive was designed for.
Do Not Overload
A clip designed for one thin cable will not hold a thick power lead under tension.
Match the clip size to the cable, and where a cable pulls sideways, use two clips close together rather than one taking the strain.
Removing Them Cleanly
Warm the clip gently with a hairdryer to soften the adhesive, then peel slowly rather than pulling.
Residue comes off with isopropyl alcohol or a citrus-based remover. Pulling a cold clip off a painted wall takes the paint with it, which is the usual damage.
Where Not to Stick Them
Not on rented walls without checking the tenancy terms. Not on anything you would mind marking. Not on a surface that gets hot.
Buy More Than You Need
Placement is trial and error, and a clip removed once will not restick. Packs of a hundred cost little and mean you can afford to reposition.
