Mount lights on a stucco facade - how to get it straight?

[andreascarlsson]

Now we're going to put lights on our house!
The facade is plastered, which means it's extremely uneven. Now we're going to mount a lamp on this, and of course, it's difficult to get it even. See picture (I know, the cable needs to be cleaned or replaced 😂).

One could sand down the facade right where the lamp is going to sit so that it rests on an even surface, but since the power cable in this case is exposed, I'd prefer to raise the fixture a few cm from the wall so that the cable has a chance to sneak in under the fixture.

I'm thinking of a base made of black modeling clay or foam rubber, that should work, right?

How do people usually do this?

What does the wall mount itself look like?

Foam rubber, etc., usually does not withstand the sun's UV rays, it dries out and crumbles.

Perhaps some type of EPDM rubber and/or washers/pipes so that the wall mount is straight, then maybe paintable sealant between the outer edge of the wall mount & the wall.

Thanks for the input!

The actual mount is a plastic plate. Quite hard, but it can be bent. But it's obvious that it wants flat ground.

You could build a small base of mortar/outdoor putty as well.... 🤔
But then clay feels easier. It feels like you want something that can be shaped and cut off if it becomes too big, etc.

Attaching flat things to a plastered wall, however, feels like it should be done every day, there should be some clever trick, right?

Stainless steel washers between the wall and fixture?
