How to fill cracks between wall and ceiling

[Andy Hide]

Having had walls and ceiling replastered a slight crack has appeared between the ceiling and wall. I think this is normal and relates to slight movement of the building. The edges were not taped when the plastering was done because apparently if you do this can cause a whole chunk of plaster to be dislodged from the wall should any movement occur. Any thoughts on this ?

My question is what is the best way to fill these joints ? If you fill with polyfilla surely they will crack again ? Coving would of course hide the join but I don't want to do that.

Would acrylic decorators filler do the job as it should be more flexible ? Does anyone know a good make of filler that has worked in this situation and stopped the crack from re-appearing for a substantial amount of time ?

Decorator's filler will do fine. Score the crack with a pointed object, so that there's somewhere for the filler to go, then apply a thin bead with a sealant gun and smooth it with a wet finger.

I was given a tube of Vallance Decorator's Caulk by someone working on my house - and this is far and away better than anything you can buy in the sheds. You may get it from a BM - but I'm still struggling to find a supply of the stuff. Note that the tube is slightly longer than the shed ones - so you'll need a professional length sealant gun to go with it.

I usually get it from a trade decorating suppliers.

yep. Can do.

Yes, definitely. I have filled up to 1 cm wide gaps with it. Bees Knees.

Does anyone know a good make of filler that has worked in

I am using a Dow corning caulk. It will take maybe 10% movement without cracking. That's enough to cover most cracks after a house stabilizes. but not enough to cover a house still drying out.

Its easy stuff to use, because you can use water to smooth and to remove surplus it before it sets. A wet finger works wonders. As do wet sponges.

You can paint it within an hour or two, Though it takes days to set completely.

Its the best possible thing for this.
