Plastering Of Walls After Paint Sealant Is Done

[ArchAngelz 0]

Hi,

I would like to ask a question about plastering of walls.

My contractor intially said that my walls do not need to be plastered, and hence proceeded to paint primer sealant on it. After the primer sealant is done, it is quite apparent that the wall is uneven and hence, I thought of doing white plastering.

However, the contractor now says it is too late, that we cannot apply white plaster onto walls to which primer sealant has already been applied.

Is this correct? Or is my contractor trying to get out of doing more work? Why is it white plaster can be applied even to painted walls, but walls to which primer sealant has been applied cannot be white plastered?

Any help would be appreciated.
