The more time and effort you put into proper preparation, the easier your painting tasks will be and the longer the paint job will last. All of the steps involved in preparing a house for painting also require some precautions that are serious enough that they can’t be ignored. Eye protection is essential to guard against dust and flying paint chips, and you need to wear a dust mask or respirator for protection against dust inhalation while sanding. First, you need to complete any necessary repairs. If the weather has rotted or splintered siding or trim boards, for example, they need to be replaced or re-secured before proceeding. This includes repairs to windows and doors, weatherstripping, roofing and any other damaged areas. Don’t think that fresh paint over a cracked board is going to be the answer — you’re just asking for trouble down the road.
