Not with the immediate problem but what you would have found a help is
a "Plasterers Derby".

The Wickes one is a tenner and is a four foot length of aluminium with
handles on. You use it to go over walls to finish plaster off. It is
fairly easy to use.


But that doesn't alleviate the ridges which is caused by the trowel scraping
the plaster ie the trowel is not getting swept across the plaster at the
right angle.

You can hear and feel this when it happens.

ps a derby is for levelling the plaster.
