Though the refinished area can be used as normal after 12 hours, and your new finish will be fully cured in approximately 2 weeks. Normal usage after 12 hours will not hinder curing or damage the finish.
THEREFORE, Keep the surface open to the air to dry when not in use.
Do not set and leave mats, wet towels, soap, bottles, etc. on the surface, as that traps moisture and may alter uniform curing.
Any surface dust /lint in the final coat (dust bumps), if any, will fade and wear off with normal cleaning and usage in 3-4 weeks. This is normal and unavoidable without sterile ‘clean rooms’. Picking at these may create a void in the surface.
Leaking or dripping faucets must be repaired.
