Freshly skimmed bathroom wall help

[tapper]

Hello all,

New tiler here advice needed

Just had a customer's bathroom wall skimmed as it wasn't in good shape after the tiles were removed.

The plasterer told me it will be good to tile in 3/4 days which I thought was to soon.

Anyway if I do give it 4 days would it be okay use mapei plaster primer with mapei mapegrip plus adhesive? The tiles are ceramic metro.

Thanks in advance for any help.

3 weeks minimum - but that never happens in the real world.
Mapei is good adhesive.

Tech sheet for adhesive says 4 weeks for fresh plaster.

Not that anyone has ever waited that long I doubt.

I find these sheets ambiguous as they don't seem to differentiate between going on plaster board or going on bonding that may of only gone on yesterday and there must be a difference between that .

If I've read the tech sheet correctly it says a primer isn't needed, I've been told it will definitely need it.

I will leave it 3 weeks but I am now confused about the primer, what would you guys use?

That's because they use contract adhesive which allows the wall to breathe and dry through it , oh hang sorry that's what they say about the paint, sorry contract paint allows the wall to breathe through it

Why are people still using plasterers on areas are going to be tiled ... plaster is week and needs prepping, give your self more income and rectify the wall yourself with products like Mapei nivoplan or Kerakoll kera level ... stronger and ready for tiling in hours
