Cuprinol Ultimate Garden Furniture Oil is a high performance treatment for teak and other hardwood. It has a special formulation that provides longer lasting protection than traditional Teak Oil and works in 3 ways. Waxes increase the ability of the wood to repel water, protecting it from the weather. Oils penetrate to replace the natural oils lost through weathering. The natural clear or lightly tinted colours enhance the grain pattern and appearance. Regular application will help prevent the wood from greying and maintain the original appearance of your garden furniture.
