After setting the leak
Before you can determine exactly what the damage is caused by a leak, it is necessary to ensure what was causing the leak in the first place has ceased. In my experience, is generally advantageous to use a trained professional to ensure that the cause of the problem is properly attached before attempting a backdrop in any form whatsoever.All surfaces must be completely dry before painting or decorating can begin, including the materials that you can not see. As a general rule, it is best to water-damaged areas to leave at least four weeks before the decoration, the base material of sufficient time to dry it.
After calling a plumber to see if the problem is one thing certain, what to do next depends on the severity of the damage to the affected areas. If the plaster is still intact and not loose in any way, could be stored. If the patch does not crack or fall, you should be fine to decorate.
As you decorate areas damaged by water, is a good idea to stain blocking paint to apply. It is noteworthy that for applying a paint stain blocking, the area should be treated with a layer of fog at least one vinyl matt emulsion comprising diluted with water for about 40%. There are two ways you can block the stain to apply the first method is to patch the entire block area to apply the stain so the paint job is not to invade. Once the areas are treated with a stain blocking solution should be possible to decorate the usual way to start without the need for specialist equipment.
