Deck restoration usually takes 3 days to fully complete depending on the size of the deck, its condition and of course, weather conditions at the time. If a deck is stained before it is totally dry, it will usually peel or chip within the first year. Some contractors will get the job done in 2 days. They forget that the wood needs to be completely dry and free from deep moisture. Decks usually don’t fully dry in 1 day. It is best to wait for optimal weather conditions instead of rushing the job.
