This long-lasting, zero VOC waterproofer derives its power from juniper — nature's best natural preservative — and is safe for people, pets, and the environment. It penetrates deep into the wood to control moisture flow and prevent decay, mold, and mildew. Use on raised beds, elevated planters, wood furniture, even railings and fences. Invisible when dry, it allows your wood to age naturally over time. Easy to apply, and cleans up with just soap and water. Vermont-made.
