It was a *bad* idea to get WIFI here at the bungalow. I can bug you all sh*tless all the time and do no actual work :)
Just knocked the skim off the bad walls in the new bathroom.
According to my 6' straightedge, I need to fill in some areas (which are back to brick between otherwise very sound undercoat) to depths varying between 1/2" and 1 1/2" (!!) thick (bent wall again).
In a couple of places, there are slight hollows on the undercoat, which would ne nice to flatten, though tile adhesive could be made to handle these.
I'm not bothered about skimming as I'll be sticking tiles all over this lot and less layers the better IMO.
So - what would be the best undercoat plaster to use? I want to slap it on and rule it off flat, mostly using the existing plaster as a guide (except for hollows previously mentioned).
Finish is irrellevant as long as tile adhesive sticks to it :)
I assume with the 1 1/2" deep area, 2 coats would be a better bet?
Is this a time to be using plastering sand (never added that to any plaster before)?
Thanks in advance as always!
