Sanding back filler

[purpleroad]

Been filling holes then sanding but as in photo white from filler has come through first coat. Do I need to sand all filler back except stuff intended holes or lines?

The filler is sucking in the paint, that's why it shows through. You'd normally put a mist coat on new plaster, but in your case, it'll juts be putting on a few more coats there to even it up.

Or seal it with zinza?

There are lots of cracks under the coving.. Shall I just paint over it wh

en cutting in?

If you've got some floating round yes; if you've got to buy some, then it's a lot to buy for such a small area.

Edit: fill the cracks with caulking first.

Shall I scrape out the flaky bits then put caulk in? Regarding the filler, is it best to water down paint so a primer then use zinza on top of that or use zinza straight onto the fresh filler?

 

[Doggit]

If you scrape out any loose bits, then the caulk will grip better. When you get some new filler done, use the 50/50 emulsion and water to seal it first, before you paint the whole wall.

Sorry, but as I never use the Zinsser, so I can't help you on that last one.
