Repairing plaster

So I removed the wall paper in my entrance way to find this cracked plaster above my door. How would I go about repairing this section? I can feel cold air coming in from that spot that's exposed. Name:  image.jpg

Use some setting type drywall joint compound. Mask the picture mold and the door casing. Buy or make a tool that just fits between the two piecs of wood. Press the mud into all the voids then smooth it off.
Oh, one more thing clean out whatever is still there but loose.

Not sure if you can buy a knife that narrow, I'd grind down the side of a cheap putty knife so it would fit between the moldings. You could just caulk the crack above the framing to stop the air flow if you don't have time to patch the plaster.

Look to brick point tucking tools to find something that will work to fit into the area you have to work with. I have one for just these specific reason. Can be found near the brick trowels at the box stores.

thanks for the advice i went to homedepot and picked this type of compound up:

Search Results for setting type compound at The Home Depot

hopefully this is the right one. i was planning on removing the trim moulding around the door because i think the plaster behind it is also cracking. repair the whole section and then put the moulding back on.

The easy sand should work well. Remember to only mix up what you can use before it sets up. Any leftover mixed mud needs to be thrown out [it can dry rock hard in your bucket or mud pan] If any of the exposed edges of the plaster are dusty [and the dust can't be wiped off] it is usually a good idea to prime those areas first.

I've never applied mud directly over wood like that before but no bigger than the area is it shouldn't be a problem. If further scraping reveals a big hole, using a scarp piece of drywall makes a good substrate to apply the setting compound to.

All the easy sand is pretty much the same except for the work time. What you bought will have a short work time but that also means it can be sanded or recoated sooner than a setting compound with a longer work time.
