Attaching to surfaces that could never be sewn.

Walls, panels, housings and equipment all become usable.

One face carries the hooks or loops.

The other carries a pressure-sensitive adhesive.

That opens the application up enormously.

It also introduces the failure mode the product is known for.

Because the hook and loop engagement is rarely the weak point.

Almost every complaint is a bond problem rather than a fastening one.

Surface preparation is usually the cause.

Dust, grease and release agents all prevent bonding.

Low-energy plastics resist adhesion inherently.

Powder-coated and textured surfaces limit contact area.

Clean, dry surface, firm pressure along the whole strip, then leave it.

The surface must be above the adhesive's minimum temperature.

Pressure activates most pressure-sensitive adhesives.

A roller works better than pressing by hand.

Bond builds over hours rather than instantly.

Loading it immediately is a common reason a strip lifts at one end.

Heat and sustained shear load.

Many adhesives soften as temperature rises.

A strip carrying continuous downward load will creep.

Intermittent loads are far less demanding.

Where the load is constant, mechanical fixing is more honest.

Outdoor and vehicle applications combine both conditions.

It is the property that matters most in use.

Hook and loop is designed to be pulled apart by peeling.

That peel force acts on the adhesive as well.

The tape must hold against exactly what the fastening generates.

It does so every time the fastening is opened.

Higher-specification adhesives exist for demanding surfaces and are worth the difference.

Usually with residue, and sometimes with damage.

Strong adhesives leave material behind on removal.

They can also lift paint or veneer.

Heat and solvents help remove residue on suitable surfaces.

Removable-adhesive grades exist where the surface matters.

Testing on an inconspicuous area first is worth doing on anything finished.

Convention puts hooks on the fixed surface and loops on the removable item.

Hooks are harsher and catch on clothing and fabric.

Loops are softer and safer where people touch.

Hooks exposed at low level collect lint and debris.

That gradually reduces the engagement.

Following the convention keeps the harsher face out of contact and out of the dirt.
