Wood preservatives are chemical solutions applied to wood to protect it from decay, insects, and other forms of damage. These products help extend the lifespan of wooden structures, such as decks, fences, and furniture, by creating a barrier against moisture and pests. There are various types of wood preservatives, including water-based, oil-based, and borate treatments. Each type has its own advantages and is suitable for different applications. Proper application and maintenance of these preservatives are essential to ensure effective protection and longevity of the wood.
