New plastered ceiling

leaskovski · 8 Jul 2013 at 13:17

Just had the bathroom ceiling in the flat that is let out re-skimmed as part of having the bathroom referbed.

Im pretty sure you do a mist paint first before putting the final paint on. Anyone recommend a paint to dilute to do the mist paint, and how much water to dilute with it?

Also, do I really need to sand the ceiling first? The finish looks pretty good.

Have always used Matt emulsion with water mixed 50/50 for mist coat.

If the plastering is good, you might get away with any rubbing down, but I always like to give it a light rubbing to give the paint a key,usually use a 400 grit paper, maybe 320, anything much coarser leaves scratches n the plaster.

The plaster will absorb the paint quite a bit. You dont need too much water in the emulsion tho.

Prior to applying the first coat of paint, give the surface a scrape to remove any little nibs and bits. Make sure the blade is nice and level so you dont leave gouges/scratches on the surface.

That is why I prefer to use paper on a solid block,or my orbital sander to avoid the gouges.

Cheers all. The ceiling was artex previously and we had it skimmed. I'm wondering how long I should leave it for it to dry. The colour is pretty consistent, and it was done on Tuesday or Wednesday last week. Hmm, I'm pretty sure it looks dry now.

Should be totally dry by now, it's only a skim, I work on around 4mm per 24 hours to dry.
