@datsroj-- Please explicate.

3. hard to see in video but it looks like its keyed fine from the back but the front coat is way to thin. It appears that its only 1/8 to 1/4 thick where 1/2 is the standard. It appears that if you used a scarifier to actually scratch the coat for the brown and finish coat that you would scratch right down to the lath.

4. has more waves than michael jacksons jerry curl. Apply it with the correct thickness, then use a darby, slicker, or rod to make the wall true.

1. used rib lath where flat would of been fine, rib lath used for ceiling work.

2. where new work meets existing wall the corner wasnt chipped back to allow corner right so the new lath could be tied into existing. Or it could of been chipped back and you could bend 2 inches of flat to wrap the corner. Im not saying it wont work but certainly wouldnt of passed inspection from a competent inspector and a crack will likely present itself.
