Papering over plastered walls

[daisylou]

Hi

After a damp proofing course last October the walls throughout my house were re-plastered to just over 1m in height. I was advised to wait at least 6 months before decorating. I am now wanting to line and paint. However, I keep reading conflicting information about how to deal with the plastered walls. I have sanded and cleaned them and now need to know if I need to apply a primer coat or size the walls or both and if what order?

Thanks

Youll need to size them..glue size is the best, failing that, thinned out wallpaper paste.
