is it wet john or is it just very stained from the constant water leak??
nice job again by the way
It's still wet unfortunately. No obvious change this morning either, I expect it will take a week or two to dry out at this rate
@JhnBssll how come you went down the batten route as opposed to self levelling scree and then insulation? I need to do something similar in mine when the kitchen is renewed.
It might be worth puttting some sealing oil based paint over the damp patches to stop any residual damp from rising up and rotting your ply and where the wet appliances will go putting water resistance treated timber down instead of normal ply so it’s a bit more resistant.
There are loads of gaps between the blocks, a self leveller would have ended up on the dirt under the house unless I went around and sealed it all first but I did consider it. The main reason I went for pressure treated battens was to minimise flex as we're going to tile the floor. I've levelled and screwed the battens down in to the blocks then screwed the ply to the battens so it's a pretty solid structure now compared to the old floating floor which was a bit like a trampoline in places The downside was it took a bloody long time to do, a self leveller would have been far quicker of course. Re. sealing, the foil tape and foil faced insulation board should keep anything from coming up from below. I've got some 5mm cement board to screw down over the ply which I'll then paint with diluted SBR - the cement board will stiffen the floor further and the sbr will waterproof it to minimise anything getting to the ply from above
