PL600 vs drywall compound?

[MostWanted]

Planning to install renovation gypsum on my plastered brick walls, which are very rough and unattractive, and I've read that one should glue them up. Which method is the easiest/best/cheapest? Some recommend PL600/400 and some use gypsum mortar. What are the pros/cons?

It is very difficult to assess how well it will adhere to a plastered surface.

Normally, you "nail" the renovation plasterboard onto such a wall, then you patch up any dents. Drill and insert wall plugs, quite a few and preferably in combination with glue behind.

I glued with PL 400, plastered concrete walls, put in some screws where needed because the wall wasn't straight.

I have looked at the Norgips guide regarding plaster: http://www.norgips.se/file?dnl=SE/Produkter/1_11_Gipsbruk_061027.pdf

There, they don't use any screws at all, but isn't any pressure needed apart from a few taps with a rubber mallet for the plaster to stay in place and dry?

Going to put renovation gypsum on my plastered brick walls, which are very bumpy and ugly...

6mm renovation gypsum will follow the contours of the wall, and you will end up plastering yourself to death. Switch to 13mm gypsum, and you'll have half the work with plastering/painting.
Furthermore, I would glue and also use red plugs and gypsum screws or alternatively nail plugs.
I have tried both with good results, however, I glued with Casco Superset.

I am planning to use tile adhesive/multifix to attach plasterboard to rendered brick, do you think it could work?

I was thinking of using tile adhesive/multifix to set drywall on plastered brick, do you think it might work?

We glued the drywall in the bathroom with adhesive on lightweight concrete blocks with no problem, so it should certainly work on plaster as well.

Okay, that's great, thanks, so Most wanted is indeed a cheap and fairly simple option.
