Can i get the tolerance limit for plastering surface undulation..
There is as such no limits on undulations on surface which you want to plaster.
If you want to make plaster in straight line without undulation.

You first need to make the surface on which plaster to be applied plain by applying backing coat.
the thickness of any plaster coat should not exceed more than 25mm.
if its more than 25 mm, you need to do 2 back coats/ chat coat before proceeding to plastering to avoid shrinkage / cracks, due to settlement by own weight of coat.

It depends on the

surface on which plaster is to be applied.
Cost incurred due to plastering.

Normally plaster done in 2 coats. back coat and finish coat.

Thickness of plaster should bot exceed more than 25mm during plastering.

We can have plaster of 75mm too, but its not a good idea to have such thickness as it will incur the cost of extra system and materials, which no one will pay so the thickness depends on the purpose for it is done.
