[philipcooper]

i have just had my kitchen dot and dabbed and skimmed on 1 wall u can see the joints were the boards have met is it possible to do a very light skim over things like this or have u got to plaster the whole wall again

Phil.is the wall smooth when you rub your hand over.If it is there's nothing to worry about,its the way the plaster has dried.I get it some times when i dot n dab.BUT if the wall is not smooth and you have a lip, then you've had a bad job done mate,so get them to do it again.

Is the plaster completely dry yet?

Did they put scrim tape on the joints before plastering? If not, Rip it out and start over!!

If they are just minor drying / shrinkage craks you can scrape them out and fill the will a gyproc based filler.

Once you have painted the walls you will not see the lines.As long as the wall is nice and smooth,then it could be the way the wall has dried.

You probably see the joints when light shines at an acute angle across the wall and technically you should not be able to see them.I cant think scim tape wasnt used but a one coat plaster system probably was say a three mill skim of multicoat. the trueness of the finish is related to the truness of the boards so if they are out of true then so will the finish be. Check with a 1.8m straight edge in all directions. The B.S. 5492 allows a 3mm deviation over 3mm. Any more than this and the work is substandard according to the B.S. If the boards aare ok then a coat of unibond and a further skim will sort the problem out. Make sure you tell the plasterer to finish the job to the B.S. and quote the tolerances.
