    Wall has been plastered. Noticed whilst doing base coat that there were track marks on the plaster. Now I've completed the base coat (Matt White paint mixed with water) I can see clearly that there are loads of these track marks down the wall. It looks a mess. It appears to be where there have been drips down the drying plaster (plaster too wet perhaps??).
    It looks like it needs replastering or skimming. However the original plasterers have finished for Christmas and I really think they should come and sort it out. But of course family coming for Christmas and this is the main wall in the living room.
    So any suggestions on how we could fix this now, e.g. Painting products, plaster repair??
    Alternatively I'll have to get a very eye catching Christmas tree to detract from it!!!

    hello katfish, are they drips of plaster, or more like where a liquid ran down that no amount of paint can cover? If the latter, they might be pva streaks.Try painting over with an oil based undercoat close in colour to your emulsion. Then as normal.

    Thanks. The track marks are slight indentations in the plaster so the base coat has highlighted them. I don't believe they are pva as the plasterers suggested for us to apply pva before painting. Currently I think they can't be hidden by paint as it will just adhere to the indentation.

    I did nothing to it until two weeks later when I did the base coat of paint mixed with water. The drip marks were already there but were highlighted by the painting. I believe the plasterers were meant to know what they were doing though it seems like sloppy work.

    Am trying a thicker oily coat on part of the wall to see how it looks.

    Just out of interest what does happen if you put glue onto plaster?

    pva is put on a surface before plastering. It should not be put on after plastering but for some years people did do this. The after-pva becomes a problem in damp areas like kitchens and bathrooms.
    If you're set on getting rid of the indentations then use Easifil powdered filler to give yourself a chance with the inevitable rubbing down afterwards.

    Seems like PVA has run on the plaster which you should be able to fill with a fine filler - what sort of area are you having problems with?

    I can't imagine why PVA would be going on the wall after the plaster.
