Depends on the kind you get I guess, I'd suggest looking for some description of non-damaging tape to secure them.

I don't plan on removing my lights ever so I use stronger double sided tape instead, because no matter what you get the adhesive backing is weak

The tape to apply them might. It is not a big deal since you can repaint the wall.

Depends on the adhesive used. Have you tried Goo Gone?

If the paint isn't water soluble you could use rubbing alcohol and you slowly peel it away. Although before you do this, do a small test on the wall to make sure no reaction happens.
And be careful with inhaling too much if you do this, you might get dizzy if you inhale it for a long time

Steam

Use a flexible putty knife to remove the strips and adhesive. Sand smooth, spot prime with oil-based primer over the adhesive (there's always residual glue), light skim with hot mud, sand and re-prime the mud, top coat.

Put the led strips in a casing.

To move your LED strips, try wrapping the adhesive side with painter’s tape or wax paper to protect it. You can also use a hairdryer to gently heat the adhesive if it’s tough to remove. This will help preserve their stickiness for reusing in your new place!

Good luck with the move!

tape perhaps

I have a lot of experience with LED light strips, but I'm not sure exactly what you are asking.

Are you asking how to:

1. Safely remove the strips without damaging the paint?
2. How to store the strips so the sticky side doesn't become a mess?
3. How to re-use the sticky side after your move?

1. Very carefully, and you might not be successful depending on the stickiness/paint quality combo. Use a putty knife and pull verrrryy slowly. Be prepared to touch up with a little patch paint just in case.

2. I would use strips of paper, plastic, or electrical tape to safely cover the sticky. Then re-spool the lights (buy or make a spool if necessary) to keep them from tangling in the move.

3. Don't. In my experience, the built-in sticky is one-use. Fortunately, you can use little strips of mounting tape to reinstall your lights somewhere new (I've moved with mine several times) and mounting tape is also more reliable in not damaging the paint in your next place. :)

Instead, cover the old sticky with something permanent like paper and then use mounting tape in the new place.

Stick them to baking paper 

Actually...looking closer...if you are not doing a repaint...just sand those few minor places and repaint and touch-up that small area...it's pretty minor....

Yes...you do. Scrape any dried paint off and then sand it and mud over it and sand and smooth out. Prime and paint. My son did the same thing in his room.

It’s tough to try to fill shallow holes . Maybe sand to attempt at evening out the surface , may just chip More. Little you can do.

Nah.

Nah, use a delicate tape if you’re not painting the white wall too

Typically I have to remove the shader if it doesn't have screws, get a new one if the first shader is damaged, then apply black gasket maker to the void in between the pixels. Then press the shader in evenly, wipe away the excess, place the mod pixel side down on a flat surface with some kind of weight. Unfortunately, it's not always the fastest, but it works.

If it’s Absen, I always just bang them back in to place with a soft part of my hand. Or like my thumb sliding it back into place. Some models have little screws that hold them in place as well so you could check if it’s missing those tiny screws.

Sometimes you can replace the shader itself (brand dependent)

Email hugo@roevisual.us he covers parts. Let him know the PO# on the back of the panel and he'll find the matching shaders for you

If your close the shop you can ask for the replacement shader for carbon panels. They come on sheet with the adhesive already applied. Just peel the old one off and replace with the new one. Just make sure it’s in the same orientation. (There is a lip normally on the bottom)

I have a wallpaper roller on a stick I use sometimes!! It’s just a rubber roller. It works!!

No problems. I often tour this style wall and always ask for 1-200 of them as they are the first thing to go and easy to fix without a replacing the entire module. Just be delicate peeling it off as to not remove any pixels either it.

Drywall is basically a gypsum core with paper on both sides to sandwich it for strength. Peeling a bit of it is okay, but peeling a lot of it is not a good idea.

What you need to do is get a small container of joint compound and a six inch putty knife. You will first use the putty knife to remove all loose stuff, being careful not to damage more. Then use the joint compound to resurface and feather (youtube!!!). Once that sets you will sand and resurface again with the joint compound. (oh, get a good N95 mask for this) Once you have a nice smooth surface you will wait 24 hours and then use a drywall primer. Then you will repaint the whole face of that wall with the closest match you can find unless you have exactly that paint in a can somewhere in which case you can just touch up, feathering again to blend old and new.

Seal the brown paper with bizs first or it will blister when you but joint compound on.

Intriguing indeed! Are they individually addressable pixels or regular strip lights? What were you powering them with? What’s the voltage and how many amp do they pull?

Tiny amounts of static lighting them up briefly? How odd.

Yep, check out triboelectric effect on e.g. Wikipedia. Flashes are caused by electric discharge when two charged dielectrics are being separated. Tearing off a sellotape will give you the same effect.

Thats in crystals.. this seems like static electricity

So you know when you are rolling up a hose and some water spills out...

I'm guessing static electricity.

If you turn off all lights and rub something for static electricity, you can actually see an arc between your hand and the fabric.

Not static discharge in air - I think there's enough capacitance between the strip, adhesive, and the rug/wall that when you move it, enough voltage is briefly induced in the wire that a few electrons hop over the LEDs and illuminate them.
