The widely popular type of ceiling for such homes is called lath and plaster ceiling because it makes use of a wood or a metal lath to serve as the base where the plaster can stick with.
Although such a ceiling evokes class, it is not to be forgotten that plaster lives on moisture, while wood lath dries out. Hence, a crack – or worse – a collapse on the plaster occurs. When either happens, an immediate lath and plaster ceiling repair needs to be done.
Depending on the extent of the damage, here are the ways on how to repair lath and plaster ceiling:
Prevention is always better than cure that’s why as soon as you see small cracks starting to form on your ceiling, remedy it.
- For starters, dampen a paint brush of any size and use it to get rid of dust or anything that may be in the cracks. If you do not do this, whatever you will use to seal the cracks back together will not be very effective because of such obstructions.
- As your first coating, you can use cornice or latex adhesive to fill in the gaps.
- Let the first coating dry thoroughly before you polish a plaster compound over it as your second coating. Do not hesitate put pressure on it with your trowel to even it out.
- When the second coating has been dry for several hours, it is now time to apply the last coating.

Regardless of how big or how small
- Like in any lath and plaster ceiling repair, make the affected areas extra clean. You can even vacuum the debris out, but you cannot use a regular vacuum that you use for your home because it may ruin both your vacuum and your plaster ceiling.
- How you can moisten the holes in your ceiling is up to you. You can use damp small paint brush or a spray bottle. Nevertheless, you cannot skip this step because plaster needs enough moisture to stick.
- Once all the holes are ready, apply the first coating of plaster compound to them, and let it sit for hours. After that, you can add more coatings.
For Large Damages
A part of the plaster hanging 5 inches away from the lath, the wood lath barely hanging from the ceiling joists, and a portion of the whole ceiling where the lath and plaster has once been are all considered as large damage that need immediate repair.
- The first step for this lath and plaster ceiling repair is to remove any debris that may be lodged into the area. This is highly necessary if you want to have a safe and gap-free ceiling again.
- Cut out a piece of drywall that you will be using to cover the damage. You can go crazy on the amount of screws that you are going to use to attach the drywall perfectly to the ceiling joist, but remember to keep the screws no more than 5 inches apart from each other.
- When that is settled, apply three coatings of joint compound over the drywall. Do not forget the rule for plaster application though: apply the first coat, wait to dry, apply the second coat, wait again to dry, apply the final coat, and wait for it to dry before you decorate it.
