If the floors
are a bit worn, a second coat of polish really makes a difference. It depends on what you're using. Some products you can re-coat in an hour or so, others say 24hrs. between coats. The relative humidity has a lot to do with drying times.
I've used commercial products that say not to walk on finished area for at least 24hrs. and up to a week before moving furniture around on the floor! So many formulations so little time! Where I once cleaned apartments they used Mop & Glo, Brite,Armstrong and one I don't see anymore,"Future" DEP has some good products.
If you buy from a janitorial supply business make sure to read the application instructions before buying. Some have you washing twice with a special cleaner/stripper,then rinsing three times and then drying 12 hours to over night before you even think about using the polish. This is for wood floors. Some require mask wearing and plenty of ventilation. Use a good lint free applicator too! Bonn is another good consumer grade floor care brand with several different finishes for finished wood flooring.
