Anyone have any tips for skimming onto old plaster? Managed an almost
perfect skim onto plasterboard but finding that old walls are much
more difficult. Any slight lumps and bumps mean that the you are more
likely to miss bits when trying to get a good finish.

I primed the surface first with PVA which I think helped to increase
the working time. Total thickness of the skim was about 2-3mm. Can you
go thicker than this on old walls to help cover up any imperfections ?
Applied in two coats, the second applied just as the first was
begining to set.

Also found that there were a few grit marks. Badly mixed plaster ?

When ironing out the trowel marks as the plaster is setting does
anyone have any tips on which way to work across the wall. Should you
go top to bottom or left to right? Are long sweeps, short sweeps
better ?

Any help much appreciated.

Andy.

There's no golden rule to Plastering if you feel comfy the way You apply it
then settle for that.
One tip I can give instead of having a large pasting brush in hand to dampen
plaster as your Polishing it, use a spray bottle.
