Bad Walls

[WetSaw]

The board is inherently waterproof, you only need to waterproof the joints. It can be fixed with adhesive alone. Compared to cement board it may seem expensive but when you factor in not having to tank, the ease of cutting, low weight ( important when you're trying to lug great big sheets on your own) I know what I prefer!

mechanical fixings?...i looked at their site...no screws seen...why cant they say what they mean?
play this video:-

Schlüter®-KERDI-BOARD | Video | Schlüter-Systems

They did a whole bathroom with no fixings...just tile ad to stick these panels to....am I wrong?

1st video I looked at they were using screws and washers!

That's mechanical fixing!
Drill and plug your brickwork.

incomprehensible. for me. you are not in spain?
It should work. as in italy +/-.
sand, cement, lime (with fibers). the max. primer on the bricks. (But not required).
Then waterproof all. (Mapelastic use. These works. Residual moisture)
I have always seen him do so.

Yes Antonio, I am in Spain. My concern is that I would not be able to get mortar to adhere properly to the bricks with the amount of plaster still remaining on them. A Spanish builder suggested making holes all across the wall so mortar could enter and grip. I may try a test area your way ( also lime is only in huge bags!) If I wasn't going to fix tiles @ 30kg m2 I wouldn't be so concerned.

I did not see. which was plaster.
use primer. no mortar. use type (Planitop Mapei / keralevel kerakoll).
secured engagement. as it says bricklayer is also ok. make some hole. not hurt. you could fix. also a steel mains. thin. prior to shaving.

I've had Man-flu for the past 4 days so I've not done anything. Will certainly try a test area before ordering the Kerdi board ( over €500!!)
