"Whitewash, or calcimine, kalsomine, or calsomine is a type of inexpensive paint made from slaked lime (calcium hydroxide) and chalk (whiting). Other additives have historically included water glass, glue, Portland cement, salt, soap, milk or flour...

Lime wash is pure slaked lime in water. It produces a unique surface glow due the to refraction of calcite crystals."  (from Wikipedia)

I wonder if this could be a typographical error and that the word is LIME, not TIME.
