View Full Version : New Ceiling is Painted and Setting looks terrible
24th Jun 2008, 09:35 PM
Had some Gyprockers put up some WR board to a pergola for an outdoor entertainment area two weeks ago.The installation was fast and looked like they had did a good job till I sealed/primed and applied to coats of acrylic dulux semi gloss. When natural light gets under the ceiling or when lighting hits the ceiling (down lights not installed yet) two of the sheet joins which span 4.5 meters are obvious.
Looks like plaster has sunk along the join and not been sanded properly on other parts of the join.
Where there is no direct light on the ceiling it looks flawless!
I have called them back to come look and repair, they will be coming out tomorrow.
My only concern is now that it is painted (did not notice the imperfections when primered) that it will look worse than what it does now if they try and repair it?
What are your thoughts? It obviously bugs me that it was not done right in the first place and that s one of the reasons I chose not to do it myself.

They should be able to skim coat the join and when sanded, primed and painted, you will be none the wiser... it is done all the time in repairing ceilings. But none-the-less I am sorry it did not get done right the first time, it is always disappointing......
Only comment I have is that because it is outside, I might have chosen cement sheet. Just make sure it is well painted and protected from moisture.

Typical plasterers!! They would have only 1 coated the joins I would say being a small job and wanting to finish quick. This is where salt is very handy it sppeds up the setting time allopwing you to do 2 coats with one mix on a small job like that.
Chipman is right they only need to put another top coat over and sand again and all should be ok. Provided they can get that right.
Glancing light will always show imperfections more than direct light, however it sounds like you have under filled joins.
For anyone reading this if you have an area of ceiling or wall that is affected by glancing light not just poor work on the joins. Then you may consider a level 5 finish, that is skim coating the entire wall or ceiling with topcoat to give the painted surface the same texture.
In certain lighting conditions the joins can be perfectly flat yet stand out like dogs b***** thsi is the contrast between the trowelled surface and the paper surface.A level 5 finish will solve that problem.

Thanks , that gives me some comfort in knowing all is not lost, provided their second setting attempt is better than the first!
I would imagine for best results - undercoating and repainting the entire sealing would be the way to go?
Never had great results with patching sections myself.

You will only need to undercoat the repaired section but you may need to top coat the entire ceiling... not such a task with a small flat surface like yours. (often if it is all relatively new, you can do a spot repair as long as you have the same paint and roller)
Note: if you use a roller with a little longer pile, you will get a more textured finish which tends to reduce the visibility of the joins.

Well they didn't turn up for the second time and have promised to show up this weekend .
Much harder to get tradies back when they have been paid, partly my fault for not seeing the fault at first I guess.
Chipman-when you say top coat, you are referring to a coat of paint right and not top coating the entire ceiling with finishing plater?
Also where they have sanded enough and the edge of the plaster is proud, would they normally sand this although painted or feather it out by skim coating?
On the nap, I think the roller I used was 10-12, the paint was semi gloss which will obviously show up more than a flat finish , being outside though I thought the semi finish would repel the moisture much better than flat or low sheen.

Yes, I did mean the paint....
And I would use the satin finish too.
Hope those tradies turn up soon for you,
