I repainted the internal doors of our home in an outdoor shed using Empire Furniture Paint. It has been several days now, but the paintwork is not yet completely dry. Is there something wrong with the product?
Slow drying may be due to several reasons. Low temperature in the room where painting is carried out and high relative air humidity will prolong the drying process. Empire, the paint you used, is an alkyd paint that dries by oxidization. Once the solvent has evaporated from the coat of paint, oxygen in the atmosphere produces a reaction in the binder that makes the coat of paint harden. If the doors have been painted with undiluted paint or a large amount of paint has been applied, it can take time to dry completely. Even a thick coat of paint dries quickly on the surface, but drying through to the base takes considerable time, sometimes several weeks.
