Thin Coat Plaster Seams Showing With Lighting At An Angle

We had a home built 6 months ago in Wisconsin. I’ve never lived in a home that had thin coat plaster, so I’m trying to get some opinions if I’m being overly critical about the plaster while our 1 year home warranty is still valid. Overall to me the plaster work looks good with normal daylight lighting and most nighttime lights, however when brighter lights hit the ceilings at an angle I can see where some of the seams are. It almost appears the sharper the lighting angle the more visible these areas/shadows appear. Running your hand across an area you can feel a slight ridge.

Am I being overly critical, or can/should these areas be touched up and repainted? I would assume it would not take a plasterer long to hit these areas again and have the painter blends things in, although I don’t want to make things any worse. I’m assuming our builder will push back saying these flaws are normal and why I’m trying to get some opinions since I have no experience with plaster.[/FONT]
 
Get the brightest portable light you can buy, walk through the doorways and have a look at your walls. You'll be taking the lot off!!!:-0
 
s.p.t are you saying it is "normal" on large ceilings (mainly my case) to see seams when shining light across them? Again, I have no previous experience with plaster and nothing at the moment to compare to.

No mate not at all, i've just not seen many done right, is it taped or plastered yours?
 
its plastered and its probably blue board tapered edge they havent filled them properly when skimming
 
I worked for a firm years ago that did a ceiling that was about a 1000m2 and had a glass screen right across it and they painted it with silk paint and it showed every mark in it, we spent weeks putting easy fill on it and sanding and still couldnt get a decent finish on it, some things are just impossible to get right.
 
Easy to see but hard to capture in a digital image. There is a horizontal line in the center of this image that runs the entire length from the left to the center of the light, this is where the wallboard seam between two pieces meets. Thin Coat Plaster Seams Showing With Lighting At An AngleAny help would be appreciated.
 
you could ask if they could aemes the discrepancy out, then sand it and repaint the ceiling if you show the builder what you are not satisfied with

The wall is supposed to look as good as a tape/jointed surface but sometimes you get marks showing through on certain lighting situations that were not visible to the tradesman doing it at the time.
 
Thanks for the comment. I’m not actually taking a light and shining it at an angle but in fact describing that when lighting hits the ceilings at an angle you see the lines where the wallboard seams are. As an example, we have a cathedral ceiling with a stairway adjacent to it leading to the basement. When you turn the stairway light on it projects light across the cathedral ceiling at an angle and then you see the wallboard seams. On a flat ceiling with light projecting perpendicular to it things look fine, but stepping back a ways and having the light at an angle shows the seam areas I’ve been describing.
 
i can see the seam you are on about it looks like the boards aint been butted tight and when the finish is applied you get a little sag in the joint sand and fill with mud finishing compound
 
Big gaps in the tacking, should always be filled before scrimming up,not scrimmed over , otherwise....that will happen.
 
Well i couldnt see any thing from that photo but then i am old and blind but i know no one dose it anymore but i do know that you shouldnnt butt boards up should have a penny gap, an old penny that is, we used to use a couple of clouts for spacers nailed in the joist.

Yes, I remeber penny lathes.. did not need to hessian over the joints, and if you did, you buttered up first ( filling the gap) then hessian over. So th gap was still filled.
