i did some internal rendering for a client who said they wanted sand and cement as the finish coat. so i rubbed it up to a smooth finish. They now (2weeks later) want it skimmed. so how can i get a good key in the sand and cement as i didnt devil float when the wall was wet.
any ideas?
i have been asked to render a cellar ceiling in sand and cement. i have a lot of experience plastering but never done this before.
i am concerned about how the render will "stick" to the ceiling any advise would be most helpful
