|Brush away the excess "dusting".|
The freshly plastered walls were dusted with dry filler in order to smooth the finish and "fix" it in place. We left the structure looking as if it was pebble-dashed. It is a finish that works nicely in some circumstances but not for old plaster render - for that it is woefully over-scale.
After checking carefully that the building is thoroughly dry take a stiff brush and start brushing the "dusting" from the walls. The amount you remove is a matter of personal choice - I wanted only a few areas with a rough finish so brushed the majority away. Any especially lumpy or rough areas can be tackled with glasspaper but remember the whole point of this method is to achieve a flawed facade. If you want smooth flat surfaces grab the foamcore! When you have the finish you think looks right - STOP! There is always a temptation to fiddle but this should be resisted.
Be warned this is extremely dusty work covering everything nearby. I would advise a dust-mask and vacuum cleaner. Alternatively you could get brushing outside - again wearing a mask.
|Groundwork applied and smoothed.|
|Do not waste your cash on flashy "talus",|
As before, place this somewhere safe to dry allowing a few days (or more) for the groundwork to "set".
Next part is the FINAL construction phase then it's on to painting.
