My underground room wall keep flaking, every time I repair it, the unusual concrete newly flakess rotten again. How do I fix
Answers: you should use paint for a basement or paint for a bathroom. The moisture from the subterranean vault is wreaking havoc on the paint... Try running a dehumidifier as well!
What started the "flaking" contained by the first place? The problem you describe is usually caused by not properly cleaning and preparing the nouns you are patching. Wire brush and clean nouns with concrete cleaner. Allow to dry thoroughly, consequently apply patch.
