I have had 3 separate groups of plasterers to work on various areas of my new house and they all complained about how quickly the blockwork sucks in water and is prone to cracking.
On the photos you can see how one group of plasterers left the job one afternoon, everything has cracked and in one place the hardwall had set away from from the block so it sounded hollow. The following day the same group used rendering mesh (comes in rolls of 1m width) and put it everywhere over every single wall.
I would have been happier if they had taken down the cracked hardwall and started again...
On another section of the house I tried to take off a couple of plasterboards stuck with drywall adhesive onto the same type of blocks, and it was very very hard and impossible to remove from the blocks, it had become one with the blocks. If drywall adhesive is so good, why not use that instead of hardwall which is so delicate?
