As described in the book, Best Practices Guide to Residential Construction Chapter 5, Interior Finish:
Interior finishes are the most visible and, on a square-foot
basis, often the most expensive components in a house.
However, since many of these products and materials are
marketed directly to consumers, they are often not well
understood by builders and designers. Making good decisions
on such finish materials as flooring, carpeting, and
lighting fixtures can make a critical difference to homeowner
satisfaction. The builder or designer can play a key
role in helping the homeowner choose finishes that are
well-suited to the intended use, as well as providing the
structural support and prep work the materials require for
good performance.
Veneer or skim-coat plaster has, for the most part, replaced
traditional three-coat plaster in residential work. It consists
of a single coat of plaster 1
/1
6 to
1
/8- inch thick over a special
type of gypsum board, commonly called blueboard, which
is treated to bond well to plaster. Although the finished job
costs 30 to 50% more than standard drywall, veneer plaster
has a number of advantages over drywall:
- A pleasing, smooth texture that is very similar to
traditional three-coat plaster.
- A harder, brighter surface that resists dents and nail pops.
- No raised seams, tape bubbles, or other imperfections
associated with drywall.
- Greater mass reduces sound transmission.
- Quicker installation: about two days for a typical
house, and it can be painted 24 hours later.
- Requires no sanding, making it particularly good for
remodeling.
Surface Preparation for Interior Veneer Plaster Ceilings & Walls
Skim coat prep work is similar to drywall
with a few exceptions. Because the finish coating is less
than 1/8 inch thick, the boards must lie flat in a plane. Other
than that, the board can be hung pretty quickly with few
concerns. The screws can be left flush with the surface,
and butt joints can fall anywhere. Expanded metal corner
bead goes on all outside corners and self-sticking mesh
tape goes over all seams.
Some plasterers prefer to apply the finish with baseboards
and door and window casings already in place, protected
with masking tape, so the plaster can fill in any
waviness in the board behind the trim. Otherwise, install
1/8
-inch plaster grounds at the baseboard and around all door
and window openings to guide the trowel and produce an
even finish.
Application Procedures for Interior Veneer Plaster Ceilings & Walls
Using a 12- to 16-inch plaster trowel, a
first scratch coat goes over all flat seams and then the finish
coat is applied right away. If the seams are allowed to
dry overnight, they will need to be wetted first or the dried
plaster will suck too much moisture out of the finish coat,
leaving a weak joint. The same is true of cold joints along
a wall. If a wet edge is allowed to dry out, it should be
rewetted. Otherwise it will be difficult to blend the new
plaster into the cold joint.
Different brands and types of veneer plaster get
slightly different treatments, but in general, the finish coat
is troweled on in one or two passes and troweled smooth.
Once dried, small imperfections or voids can be misted
with water and fixed with standard joint compound.

Paraphrasing from this document: USG uses the term shadowing in this document in describing the visual effect over gypsum board joints caused by the lower moisture absorption rate (take-up) and lower capacity than gypsum base face paper. Shadowing at joints occurs where veneer plaster is applied over tape joints, requiring a second coat to completely hide the tape, providing a visually uniform surface. USG Advises: "This [second] cover coat must be allowed to harden and dry before plaster application is started.
