Untreated wood is vulnerable to moisture as well as insect pests, such as termites. Wooden steps and patios located outdoors can quickly absorb rainwater and snow, causing the wood to warp, erode and eventually rot. Treating wood with a water seal helps it repel moisture, blocks harmful insects and keeps the wood looking its best.
