Mist coat before filling old walls

[ando]

Hi,I have a hallway which has been stripped,the walls are really old and are gona be lined most of the walls are back to plaster but there is a lot of filling to be done,do you think it will be ok to fill these without sealing them,I will be sizing the Walls before lining many thanks

No, the filler won't grip. Dilute PVA is best.

Thanks,what pva all the walls first

No just the bits that need filling. The odds are that you have lime render which is very crumbly. The pva will harden it up - then you can fill it.
