Thanks mate, much appreciated.
A bit of progress today...the blue foam/polyfiller “molehill” now has a coating of Wood glue/sand that will provide some texture plus toughen up the exterior.
I might prime the remaining blue foam that is visible, before moving on to work on the floor of the cellar...it needs sealing in to protect it before some of the later stages, and probably less messy to do it now before I sort the floor.
