In the outdoors, bare wood is destroyed by the forces of nature - sunlight and water. Protect the beauty of all your exterior surfaces with Circa 1850 DEX Outdoor Oil - a bio renewable wood finish comprised of natural plant oils. This hand-rubbed, marine grade finish penetrates deep into the wood fibres to protect against drying and weathering. Circa 1850 DEX Outdoor Oil is the ideal finish for exotic (teak, mahogany, ipe), coniferous (cedar, fir, redwood, pine) and deciduous (maple, birch) wood. Use it to protect furniture, decks, woodwork, boats and raised garden beds.
