Lath and plaster

Take off all the old lathe and plaster and plasterboard

Very difficult to effect a repair to lath and plaster walls especialy if areas have blown and falling away. The plaster is held in place by the surplus that squeezed past the laths when it was origionally plastered, setting and holding it in place, over a lot of time this bond fails. So really the only effective solution is to remove and board.

First option I always suggest, is to take all the lath and plaster off if 70% of the walls are in bad state i.e blown, or soft. Second option if the lath and plaster is 25% blown and to keep dust to a minimal is to remove loose areas secure the entire wall back to the joists 600mm apart with thin type washers preferably the ones from topps tiles £5 a pack of 50 got to be them ones. Make good to removed surface areas with either plasterboard, bonding or both to get correct level to existing surface and mesh the full wall to prevent further cracks. Should be done on all lath ceiling re skims too.

Lath and plastered walls that have blown are not ideal to patch repair best repair is to board and reskim regards sdg
