i am building my first house and I don't really have anyone that can give me advice on the plastering job that has been done....generally the house looks reasonable although one wall has like spider web looking cracks through the whole plaster..... is this normal.... do they need to do another coat on this? :rolleyes:

You may be right Skew...could be a thickness of top coat.

Jodes, who did the plastering? Contractors?
If it's just Gyprock sheets, you may be able to get away with sanding... gyprock really shouldn't have any "coats" in the first place, except over joints.
If it's rendered over bricks or laths, the repair depends on a few different things; like deeply the cracks penetrate and just why it cracked. Too wet a mix? The bricks weren't properly sealed?

I am really naive when it comes to this !!!!!!
I just don't "get" the lingo but what I do know is that the brick walls have been rendered and then the "white stuff-plaster" has been coated over the top....once..... yes a contractor did it...... all the walls in the house are all nice and smooth except this wall.... it is smooth then course over all the cracks..... the cracks are a good few mil.... sort of makes my wall look like a jigsaw puzzle :eek:
just want to say I really apreciate all your advice.... if it needs to be fixed I sort of want to know why it is like this and why only one wall.... my first initial thought was that because the week it was done was really hot.... like mid 40's all week so I thought maybe it set too quickly..... is this possible or am I being a typical blonde!!!!!

I'd say you're probably spot on. It could be for other reasons, hard to say sight unseen, but I think you've put your finger on the most likely cause.
I'm no plasterer, although I've put up my fair share of Gyprock. (That's lingo for the sheets of plaster. :D ) But I do remember being taught that in hot weather the brickwork should be wetted first to help prevent drying out too quickly and cracking...

I could only offer a professional opinion on presentation of a pic. ;)

tap the area around where the cracking is and notice what it sounds like.Then tap a good wall,and see if they sound different.If they do and the bad wall doesn't sound solid,then you will need to remove the render and the set back to the brickwork.If it is solid,it is probably just in the set.Have you asked the plasterer to come and have a look at it?
