When your house becomes affected by flooding, the temptation is to start the repair as soon as possible in order to get it over with. One aspect that you might want to do immediately is to start repainting as soon as the water dries up. You would like to cover up the effects of the water and the damage that was left by the flooding right away. However that is not really advisable, because of certain things. In order to help you out when it comes to repainting a flood damaged home, here are some tips that you can follow.
Exterior- You would need to clean the surface thoroughly first once the water has dried. Mud and other residues can be carried by the flood water and deposited on the walls and on the surface. There are certain products that you can use for that.
If there are any damage on the surface that was left by the water that would have to repair first before any kind of action is considered. Remember that the surface would have to be thoroughly dried out and that would take some time.
When the exterior has dried completely dried, your next step would be to remove any flaking paint on the surface. Look for any cracks or damage on the surface and fill it using some high quality sealant or plaster. Once that is done, then the surface might be ready for repainting.
Interior- The interior of your house is a different story. The walls inside when soaked with water would be very difficult to completely dry and would thus be prone to mould and mildew. It is best to have them dry first before you can assess the damage you have sustained. Only then can you decide if you to repaint or not.
If the walls inside can be dried and would need no repainting, you would still have to clean them using some specialized solution to kill any existing mould on the surface. Make sure that you apply some primer over the whole area that you need to repaint. That would provide an appropriate surface where the paint could cling on and provide a good finish to the coat. You should think about adding some mould treatment solution to the paint that you are going to use, in order to inhibit the growth of these pesky microorganisms on the surface that you are working on.
