I got a good 14 inch above my door frame, worked ok with a normal trowel :-)

My first plastering job was like this, bought a cheap trowel and cut it down to size with and angle grinder clamped in workbench, worked a treat!

Strip the wallpaper off first, the paste holding it is water soluble so when you plaster over it the water in the plaster will then start to dissolve the paste and the weight of the plaster will pull it off.

If you have washable paper on the walls, the plaster will not adhere to this anyway and, if you score the wallpaper to give adhesion, then the problem in paragraph one will rear its head.

You can buy a trowel at any of the 'sheds', tool suppliers or builders merchants reputable or otherwise.

The reason you cant plaster over wallpaper is because the moisture i the plaster would make the old wallpaper peel.

I know its a hard job removing old wallpaper, but you have to do it fo reskimming the walls with plaster.

To give yourself a better chance of a decent finish,don't forget to chamfer the edges and round off the corners with a file and put a bit of a curve across the trowel.

[Rob Morley]

Don't do it.

You must have low ceilings or high doors if you can't get in there with a regular plastering trowel held sideways.

Buy an 11" jobby and take it to a engineers work shop and ask could they cut half inch of either side with their sheet metal cutter.

Have you thought about removing the architrave around the doorway?

I suggested that to him in September, in the thread "the right tool for the job?", see: Message-ID:

- however, no reply. Perhaps he doesn't see them, something to do wit "diybanter".
