It is generally not advisable to paint over water damage without addressing the underlying cause. If moisture remains trapped beneath the paint, it can cause further damage and create an environment conducive to mold growth.
In cases where the water damage is superficial and has been thoroughly dried, it may be possible to paint over it. However, it is essential to ensure that the surface is completely dry, and a primer is used to seal in any remaining moisture.
If you are unsure whether it is safe to paint over water damage, it is highly recommended to consult a professional water damage restoration company. They will assess the extent of the damage and determine the appropriate course of action.
