[Shop-talk] joint compound

[Brian Kemp]

Tim - If you take about an inch off the top of the bucket, the rest may 
be useful enough for the current job, but you may have issues with it 
bonding and setting properly.  To me it isn't worth it.

I like the setting type compound for most jobs patching jobs since it 
doesn't shrink.  I normally buy the 90 minute kind so I have enough 
working time.  You have to be a pro to need the faster stuff.  This 
stuff is much harder, so you will want to scrape it down when wet so you 
don't have to sand much.  If it starts setting while using it, either 
jam it is some deep holes or big cracks or toss it.

It is common to use the finishing compound like your bucket for the 
finish/top coat as you can get it smoother.  You can also use the 
finishing compound to slightly texture the surface to match the 
surrounding area.  Dilute some finishing compound with water then blot 
it on the patched area with a sponge.  After it is dry, you can lightly 
sand if needed, but if you get it right, you can go straight to primer.
