removing plaster from kitchen walls

Best ask your plasterer. You don't need to remove the old plaster if it is sound. Just remove any loose paint and wall paper etc.

mark

wrong assumption.

A plasterer will skim it all with bonding coat to build up, and then skim a finish over that the next day.

You don't. You only need to remove anything that's loose and any excessively raise bits. Plasterer should start by bringing it all the the same level, and then do a skim over the lot. However, I suggest checking this with your plasterer.

However, if you want to continue stripping it off... An SDS drill with rotary stop and a wide flat chisel bit would be easiest for this job. You would probably damage the scratch coat underneath but as long as you don't bring chunks of it off or make it lose key with the wall, you would be OK. Put one on your list for Santa, and protective goggles too (and ear defenders if there's loads of this to do). Also make sure it has a safety clutch for when you're using it for drilling.

ah wish i had known this before ive made a right mess of dust and bits of plaster, should have waited for the plasterer to take a look and advise me
