Paint for laminate cabinets takes around 6 hours to dry. I would recommend leaving at least 6 hours between each coat to allow the color to fully dry before moving onto the next stage. You might need to set a couple of days aside for the job due to all the drying times.
When the job is done, the color will take around 1 week to fully cure and reach maximum hardness. If possible, avoid using the doors until 1 week later. If you do need to reattach them sooner, be careful not to damage them or clean them too thoroughly for the first week.
