When a wooden window frame becomes spongy and soft, and crumbles easily in the hands when touched, the window has become rotten. Learning how to repair rot and decay on wooden windows is a quick process, and a simple money-saver, for homeowners. The basic steps involve applying primer, applying epoxy, and then applying paint or stain, and a sealer. Rot may be caused by either sun, or moisture. Both elements are abundantly present in nature, and moisture is typically the more dangerous of the two. Moist, airtight conditions, such as those between a bead of caulk and a wood frame, provide the perfect environment for fungal growth, and dry rot. Failed caulking, damaged finish, and excessive moisture are all reasons that a window might begin to decay. Removing the rotten wood is the first step in repairing the window. With either a knife or a paint scraper, homeowners should dig out old paint, and decayed wood, until they uncover a layer of new wood. Homeowners then need to dry and sand the new wood, because paint needs a dry, coarse surface, for adherence. After prepping the surface, homeowners should apply a primer. Depending on the brand, the preparatory liquid is either known as primer, or consolidant. It usually consists of two liquids, with equal parts of each mixed together. The primer, or consolidant, pre-treats the surface, by soaking into the wood grain. Homeowners may have to drill holes into the frame. If dry rot goes all the way down, then drilling small, sloping holes, will help the consolidant to cover all of the gaps in the wood. When the primer has been applied, it should be given sufficient time to cure, as written in the manufacturer's directions. When the consolidant has completely cured, the epoxy may be applied. The best application tool is a trowel, so that the epoxy may be pressed into all gaps in the wood's surface, and into all damaged areas. When cured, according to the manufacturer's instructions, the epoxy should be sanded, and then either primed and painted, or stained. After painting or staining has been completed, the wood should be covered with waterproof sealer. Rotten windows are an eyesore, and an invitation to moisture problems, for a home's exterior. Understanding how to repair rot and decay on wooden windows will allow a homeowner to fix the cosmetic problem, and to save money on labor costs. Whatever the primary cause, with time, and a little elbow grease, homeowners will have no problem completing this easy repair. |
