Hi all! I have this very problem. See photo attached. As it’s everywhere, based on what has been written on this thread, I can only assume that the builders did no leave enough time for the screed to dry. Is the colour change to wooden floo permanent, or does it ever revert back to original colour when fully dried out? Thank you! @Temp @JohnMo @stanmoor @Nickfromwales
