hairline cracks in new plaster

How do you prepare the wall before skimming ?

Say how, and the 'experts' on here will give you some clues.

you included no doubt :^O

 

Here we go again. Can't you play nicely, children?

 

I am here , answered something like this before ,pva or water ,---------------------------------------------------------------------------fruit juice ,orange juice, carrot juice ,grapefruit juice ,apple juice , thats you shopping, oh yeah , sorry

 

From your OP i can assume you mean re-skim. Why else would you be taping the cracks. IMO i think you ahve one of two problems. Firstly, have you used PVA to seal the wall and if so was it strong enough? Secondly, are you plastering on stud walls? Perhaps the plaster board has not been fixed correctly and is moving under pressure.

 

Are you putting it on too thick ?

Have you tried adding a pinch of fibre bind, supposed to stop top coats from cracking.

 

Another issue could be drying out the plaster too quick. Don't allow the room to be too warm when drying. Allow plenty of ventilation but no direct heat. Turn down rads to keep the room warm, not hot.

 

Do you skim while pva is still tacky ?

If not, you could try that.

Who oh why does the OP ask a Q then we never hear from them again?

I tape up any existing cracks, then 2 coats of diluted pva

 

clever cloggs, i stand corrected

 

I get this in old houses after a season or two. I guess lime plaster has alot going for it if you have to time and money
