Sectional meranti wooden garage doors are very popular because of their unique look and security. They do require regular maintenance to ensure that they not only look good, but that the wood is protected from the elements and doesn’t rot, warp or crack. Wood is a living material which expands, contracts, absorbs and dries out, depending on the conditions it is exposed to. For this reason, it is important to apply the proper treatment to meranti sectional garage doors, a treatment that allows this expansion and contraction to occur without damaging the exterior appearance.
