What is this plaster... and how do you remove it?

[Adrian L]

As the title suggests, we have a rather coarse "plaster" on the interior walls in our new house that we plan to smooth and repaint before moving in. It is rolled on and feels like some sand/paint/plaster. I would say it's too coarse to skim coat. Apparently quite common in the 70s/80s, I've heard. It likely has regular drywall behind it.

Does anyone know what it is and how to remove it?

(Unfortunately, I don't have better pictures at the moment as we haven't gotten access to the house yet)

Seems like you have been affected by the 70s-80s "pizzeria plaster" of the worst kind, paint mixed with gravel, sometimes reinforced with cement. Not a fun job to remove.

Tear down the gypsum boards and install new ones. This is said to be the most time-efficient way. You'll also get good new surfaces that you can then paint and achieve a good result.

looks like "Artex," a thick paint or material that could be rolled, unfortunately, some contained a lot of asbestos.

Oh, how ugly! And I learned something new about the 70s. Renoveringsgips? Cover it up!

Oh dear, no positive responses.

Considering a proper wall sander but "Gör det själv" link provides a few more tips.

If you are considering sanding, send in a sample so you know it does not contain asbestos.
If it contains asbestos, sanding is not suitable as sanding is the absolute worst possible method to work with asbestos-containing materials.
