Removing Lime Buildup Before Painting Garage Walls - Best Methods?

Question

Hello
I have walls in the garage that are covered with this white chalky stuff and it stains clothes terribly if you lean against it. I think it's lime.
How to remove it from the walls so that it can be painted with normal paint?

I wouldn't wash it off, just paint it twice with emulsion paint, once heavily diluted and the other normal. Apparently, you can put an emulsion on the lime. Regards .

You won't wash it off, you'll only make mud. Remove mechanically
putty, or try to prime the walls with a primer, Atlas produces such a specific. This binds the individual layers applied to the substrate into one whole.
As for the paint, it is a white emulsion Czech production, it has anti-fungal and waterproof properties.
I'll post the name when I find it.

You have several options. You can wash it off.. Leave the algo scraping and prime it. If you want to remove this layer of lime, look for gray soap. Dissolve it in water and apply it to the walls quite generously.
Personally, I would prime this lime with an emulsion paint solution and paint it. The only thing you need to pay attention to is whether the lime does not fall off somewhere with platami.

Hello, from your post it appears that you have a damp garage. The white coating is lime and salt efflorescence. Dry the room and remove the deposit mechanically (using a wire brush). I suggest priming the walls with the preparation "ZSE - lime and cement tarnish remover" - Quick-Mix. Then (after the preparation dries) paint the walls with emulsion paint. Remember about proper ventilation of the garage (ventilation grilles).

Such ground:

after smearing it on the walls, it feels as if you covered them with liquid foil, it will bind what was peeling and flaking.
And this paint:

It is for rooms exposed to moisture, it gets so hard that it is impossible to scratch it with a fingernail.

Hello, I have a similar problem,
I want to remove the lime from the ceiling in the garage and glue the Styrofoam.
I don't want it to fall apart after a few months.
As for grinding with a wire brush, it would be a bit of work,
and lots of dust.
I was thinking about doweling these plates, but this is gel concrete and a flat roof

Maybe someone has an idea.
