Teak has dark golden yellow heartwood that turns dark brown with exposure. Its sapwood is pale yellowish and sharply demarcated. It has a straight and sometimes wavy grain with an uneven and coarse texture. When freshly cut, it has an oily feel. Teak is considered to be the most suitable species for outdoor use.
1" (25mm), 2" (50mm) , 3" (80mm).
Easy to work in nearly all regards, with the only caveat being that Teak contains a high level of silica (up to 1.4%) which has a pronounced blunting effect on cutting edges. Despite its natural oils, Teak usually glues and finishes well; though in some instances it may be necessary to wipe the surface of the wood with a solvent prior to gluing/finishing to reduce the natural oils on the surface of the wood.
