We are currently renovating our kitchen in a 1930s flat. We pulled up some lino floor which was backed with sheets of MDF. When we started to pull up the MDF we noticed some kind of underlay / screed that had been painted green but with a red core. The screed is incredibly crumbly and looks like it will completely come apart once all the MDF has been taken out.
It is possibly magnesite, but after lighting a small lump from it, there was no glow as described on some online forums. Could this potentially be a sand cement or some kind of asphalt layer?
Any ideas and advice would be much appreciated!
