Hi All,
I'm in the middle of installing a corner shower in my downstairs cloakroom. I was hoping to tile the shower area but I've found some areas of wall plaster cracked and blown. The walls are internal 100mm aerated block (Thermalite type) with sand & cement render, finished with plaster skim. The cracks tend to be along the blockwork mortar lines both horizontally and vertically. In some cases the vertical ones are right through the centre of the blocks as well, but they do not appear in the room next door.
I'm wondering if I should replaster the blown areas or whether I could leave the walls as they are and tank them with a flexible liquid membrane like Mapei Mapelastic AquaDefense or similar.
Any advice would be much appreciated.
Cheers.
