You may know the type: they come in white or gray color, and they're a meter long and about 1/2 inch wide and deep.

They peel apart and you stick the flat piece against the wall, put the wire in, and press the curved piece to snap in place over top to hide the wire.

There's a factory stick strip on the flat piece - but like much of Thai construction materials, it doesn't work. If it sticks at all, it might stick for 90 seconds. I've tried drilling and screwing them in (a big hassle if trying to place them against masonry or painted walls. Here's what I've found works:

get a tube of the UHU glue (yellow squeeze tube, German stuff). I buy it in largest sizes because it's good for many things. And Thais never quite figured out how to make glue.

Peel the teflon strip off the flat conduit piece. Put splots of glue every 4 inches (10 cm) along its length - then press it firmly on to the wall. Then go do something else, because it won't be fully secure until the next day.

I've even used the UHU glue to stick for masonry toilet roll holders and shower soap holders against dry grout. It works, but you have to let it dry 2 days. good stuff.

Try using a small concrete nail to tack them on the wall. It should hold them. I tried another way to get rid of the plastic strips on the walls. I tacked on a 1/4 inch strip of wood (depends ofn the wiring size) and put it around the wiring. Then I put concrete between the 2 pieces of wood. Then remove the wood & the concrete should stay and then paint the concrete. It looks a lot better.

Concrete plugs and screws is the normal procedure back home .

I use several plugs and screws and it works well but will give UHU a try. The new version, called Power, is instant bonding after you cote both services and let dry about 10 minutes and then press together.

Hot glue gun that uses glue sticks.

Why not use wood trim with a groove cut out in back big enough for the wires to fit. It would certainly look better.

And the termites will thank you.

My solution is to put a dab of epoxy every few inches along the two-sided tape strip. The two-sided tape holds it in place long enough for the epoxy to cure.

If you paint over the strip after that, it'll be stuck forever (or until somebody yanks on it).
