they seem to do it in a couple of hours on changing rooms. i just had a changing rooms experience i demolished a kitchen cupboard and found beautiful red tiles on the floor. took up the shabby lino to find more plastic tiles which have been sealed to the lovely red stone tiles using some black adhesive - if thats not hard enough to get up there is cement or concrete a thin layer which seems impossible to remove.
mumsnetters know everything in my experience so please help me as my husband and kids are fed up of scrubbing the floor with wire brushes and wallpaper scrapers and just want to put a carpet over it!
