Hello Sujeeta, Take care of the waves in the wall while preparing the base . The reason behind this is, when you finish the wall with the wall paper the waves in the wall is noticeable or the gap creates the bubbles in that particular area. Practically go for the pop putty or the gypsum sheet fixed for the perfect finish.

It would be better if you can consult Admixtures company like ., Myk laticrete, Bostik ., etc It's a kind of plaster STUCCO...

I want to achieve this concrete finish on walls . any recommendation on specialist or agencies who does this in mumbai
