I'm new to the forum (but not new to the advanced DIY), so please forgive me any inaccuracies and loss in translation (I'm Polish).
1. I'm looking for a ready to mix, mineral (not gypsum) powder, in about 25kg bag, that I can mix with water and apply on not very even/straight concrete brick wall.
What would you recommend, available from the popular merchants (TP, BQ, Homebase)?
On the Continent, we would use for example this: KERAKOLL KERALEVEL LR or this: Ceresit CD25.
I need to correct the levels before bathroom tiling.
2. Also, before applying that stuff, I would like to use some sort of transparent, acrylic primer ( to reduce water absorption, prevent loose sand particles dropping and to increase working time with my leveler).
3. After applying the leveller from question one, I would like to waterproof the wall and the surrounding plasterboards with the flexible stuff such as PCI Seccoral ( https://www.youtube.com/watch?v=5JzhCeRPdZE ). I am aware of the Mapei system - currently on offer in Screwfix, but maybe fellow DIYers suggest something absolutely amazing.
4. What gypsum powder is good for a quick skim on the plasterboard joints and screws (before painting). I'm not keen on ready mix polyfilas, as these can be quite tricky to sand by hand.
