We have in our house there aretwo wooden floors which had lino on them. On removing the lino we found a slurry of what looks like cement over the boards. About 50% of this is flaking off & we thought fine just chip it off & paint the floor with lime wash look. However it either comes off easily, comes off with chipping or does not budge atall. This is our holiday home & we only have a limited budget & time. Any suggestions ? I have several other questions but do not know how to start a new topic?
