We have moved into a villa from '71, where a basement room has acted as a recreation room. This room has a number of troublesome walls that we would like to sand down and paint.

However, I have no idea what tools I should rent to do this.

Some of the walls seem to have some form of "texture plaster" or similar. It looks like someone just took some plaster-like putty and made patterns on the walls with it. Picture is here: http://i.imgur.com/YqTWhrJ.jpg Since this is just plaster, I assume it can be sanded down fairly easily, but I still don't know what I need :)

However, there is also another wall that is more troublesome... It has "stones" embedded in it. The stones themselves are not hard, you can easily penetrate them with a screwdriver or anything. The "putty" or whatever holds them in place is harder. Picture is here: http://i.imgur.com/bvGQGpN.jpg

("the brick closest to the camera seems quite easy to remove. The loose lamp cord has already been removed)

I assume I need some form of electric sander, where you can attach a construction vacuum, but what exactly should I be looking for?

I believe in crowbar and patience.....

Doesn't sound like it would get particularly smooth with a crowbar :)

The plaster is, as mentioned, very "soft" so it can be removed with something like a putty knife, but it's going to take a hell of a lot of time, and it won't be smooth underneath, instead there will be quite a few residues left.

The "stones," on the other hand, I don't know...
 
Yes, I also believe more in cutting it off from the side/underneath than trying to grind it down. Maybe some sort of really sturdy chisel-like tools? Any potential damage to the surface will hopefully not be bigger than what can be filled...
 
Are you only talking about the stones now, or the gypsum wall as well?

The gypsum structure feels like something one should be able to sand down quite easily(?)
 
Waterjet cutter if available for rent, otherwise angle grinder.
 
I should add that I have no idea what the stones are held together with, but it's strong! Mortar maybe?
 
Isn't it easiest to embed the stones in plaster?

Hmm, that might be an option.
I would be losing a few cm of the room's width, but it might be worth it...
 
car hammer with a wide chisel first, then either wide putty the wall or sand it with a concrete sander
 
Car hammer with a wide chisel looked perfect for this!
I'll have to find somewhere to rent it + a construction vacuum cleaner, then I'll really go to work on the wall...
 
Cramo has a good range, Hilti has a lot of chisels of different kinds and widths.
 
And Cramo has a location in Bromma just 2km away or something by car... :)
Thanks for the tip! I'll go there and see which car hammer + wide chisel they recommend, and then it's just full steam ahead!
 
Google "giraffe"
A wall sander that painters use, it comes with a vacuum cleaner that goes with it. Wonderful tool.
