Ceiling Plaster Crack
Ceiling plaster cracks can be caused from your house
settling with age or movement as temperatures fluctuate between hot and
cold. Hot and cold temperatures can make some building materials expand
and contract. Over time this can develop cracks in your walls and
ceilings.
Home Repair Tip: There is very little that you can do, to prevent a
plaster ceiling from cracking. If it's going to crack, there is nothing
you can do to avoid this. However, these cracks can easily be repaired
using
Fiberglas drywall tape and finishing it with drywall joint compound.
I have probably made this repair sound easier than it is, but there is
another alternative. You could fill the crack with a good paintable
caulking. Make sure that the caulking you use is paintable, some
silicone-based caulking aren't paintable. If the caulking can be painted
over, it will save paintable on the tube of caulking.
If you choose to use the caulking or repair the ceiling crack with
drywall tape and joint compound, the crack could always come back. If
this is the case, maybe there's a structural problem within the house
and a contractor should be contacted to examine the ceiling.
