How to fix a flashing drywall plaster repair?

Anonymous user 23/02/2024 - 3.14 PM

I fixed some damaged plaster in the drywall (with Tetrion all-purpose filler) and then sanded and painted it with 3 coats of white emulsion - but you can still see where I've done the repair. I think it's called flashing, and it looks awful when you shine the light on it. Question is - how can I fix this now? Besides not shining the light on it ;) Thanks. EDIT: I used a roller with the emulsion, not a brush.

Are you a tradesperson and able to answer this question?

Tetrion filler has a reputation in the trade for doing this, as a tradesman I would never use it. For future reference use either Pollyfilla or Easyfill on walls, if you have Tetrion use this on woodwork only...In answer to your question any area that is flashing use either stain block or oil based undercoat, lightly rub down the surface and apply a further coat of emulsion, hope this helps

On plaster walls it is best to use easy fill, unlike tetrion it doesnt contain cement compound which makes surfaces flash. If the walls were previously rolled & you are touching up that area with a brush then this will cause the flashing so recommend rolling the area till the flashing disappears. It also depends on what emulsion your using if its vinyl silk you cant touch this up you will need to repaint the whole wall

Hello I would have thought you could use gyproc easifill over the current filler spreading out a few extra inches to feather the edges into existing wall/plaster work. Do two coats each time extending a little further out. You could then sand it to a smooth finish but not far back enough to expose the filler you have had a problem with. Alternatively if it is that unsightly and horrid you could get the area plastered. Thanks Matt
