External wall - bonding allowed up to 2" to floor
Internal wall - skirts removed, bonding added to fill gaps where plaster came off allowed ?
I thought you could bond anywhere?
Never skim (plaster) or bond right down to the floor.
Bond on any internal wall.
Would not recommend bonding on an internal wall that is an external elevation.
Geddit ?
For example: the inside of the walls under bay windows are notorious for damp. Putting bonding on that wall will make matters worse, use a 5:1 render with a waterproofing additive like febtite or similar, and skim over with neat thistle plaster.

Got it, luckily not much bonding to be done on external wall..

PS. The reason a 5:1 ratio (5 sand to 1 cement) is used, is that there is a lot of expansion & contraction in old mortar walls (movement) and a 3:1 mix is too hard and will crack. 5:1 will flex with the wall as it is a softer mix (Lime may be added to increase flexibility)
