As we move on to the second fix, I'm at the stage of trying to convert from dusty / muddy floor to a cleaner environment.
Gradually vacuumed out areas and sealed the screed with a watered down pva to stop it dusting, mist coats will be going on the plaster. No muddy boots allowed inside.
Now debating between the large dirt trapper mats on the outside and inside and or the plastic tacky surface sheets/ mats.
Thoughts?
