Plastering the right way for the property
The correct approach depends on what is behind the surface. A 1930s semi in Cheam with solid walls and a sand-and-cement backing coat needs something different from a 1990s flat that was dry lined from new, and a Victorian terrace with lath and plaster different again.
We check that first. Getting it wrong is why plaster sometimes fails within a couple of years — new material applied over something that was never going to hold it.
