Homeowners may save a substantial amount of money by learning how to repair rot and decay on wooden windows. The process involves putting on a primer, adding an epoxy, and finishing with paint or stain, and a waterproof sealer. Windows will look as good as new, instead of feeling spongy and soft, and crumbly when touched.
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.
Applying primer prepares the surface for further repair. Different brands may use the term “primer, ” while others will use the term “consolidant.” The material usually contains two equal parts of two different liquids, which the homeowner will mix together. The primer’s job is to pre-treat the surface and to soak well into the grain of the wood.
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.
A rotten window is both an eyesore, and a beacon for fungal growth and moisture problems. Homeowners who learn how to repair rot and decay on wooden windows, however, will easily be able to fix this cosmetic problem. Learning this simple repair will also allow homeowners to save a substantial amount on labor costs.
