Well i finally got down and dirty with the tiles and adhesive, but not before I put down the Durabase CI mat to decouple the tiles from the screed. I wanted to make sure any shrinkage was covered. Its interesting stuff, a kind of rigid waffle that is cut and then stuck to the floor. Allegedly it allows screed floors that aren't fully dry to dry out buy not trapping the moisture, giving a route to pressure adjust and balance.
Well it was cut and stuck, the indentations filled, more adhesive and the tiles laid over. Time will tell if it does its job and if on e still gets as solid a base. It did add a stage but probably not more than an hour and an extra 30% adhesive.
I also used the LASH tile levelling system. This was the cheapest of the systems and didn't require any tools. As far as i can see the only shortfall of this is the lack of an edge clip which means that there is no additional support to the base on edges and potentially your tiles could run slightly in that direction. In terms of ease of use though, 10/10.
Meanwhile John is busy on the walls, doors (Eclisse pocket sliders are always a bit tricky when you haven't done one for a while, and the instructions are some of the worst on the market!), and leaks – yes we have one mystery leak on an exposed elevation that is keeping one wall VERY wet. The hunt continues. The new oak doors came too and we will do a post on those separately.
The Apprentices are on the first lime skim coat downstairs and its all starting to look a bit closer to being a habitable room.
Pics to follow soon.
