New Plaster - Prime or not?

[infidel]

Hello folks, just looked at a job that involves tiling new plaster walls. Plaster is over 4 weeks old. Will be using MapeiStik tubbed adhesive.

Am I right in thinking that I don't need to prime with tubbed adhy?

Cheers

some tubbed adhesives you dont have to if you brush down the walls.. but i always prime not only as a precaution but stop the sticky drying out to quick on fresh plaster...
prime with bal apd ratio 1:1 or with bal bond ratio 4:1

If in doubt, prime it out

i have just started using nicobond unique bagged gear. no priming needed sets in one hour, cement free and non slip. £10.60 for 15kg bag.

If there is acrylic in the mix of the tub gear then just brush down the surface and tile. Should say on the front

I always prime, then never any problems, customers love it as it shows them you a professional tiler.
