Ayan is a tropical hardwood native to Nigeria. It is pale yellow in color and its heartwood can range from a lemon-yellow to golden-brown, sometimes with dark streaks. It has a wavy and interlocked grain pattern, and when quarter sawn, it displays a striped and mottled figure. Its surface has a glossy sheen with a fine, even texture, and it can contain silica particles. Ayan is often used for windows and doors, but it can be challenging to paint or coat due to its tendency to burn through the finish. To successfully paint or coat Ayan, it must be de-oiled and a blocking primer should be used.

The heartwood of Ayan is resistant to preservatives and the wood is classed as moderately durable.
The drying and seasoning of Ayan is dependant on a number of factors; the speed in which it is processed after felling and logging, the method of drying and the specific kilns or location (if air dried). Generally the care taken by those processing the wood will have an impact on its drying and seasoning. As an overview; Ayan - It dries quite quickly and must be seasoned carefully, with protection from sunlight and strong winds while drying; otherwise it can twist and split. In service there is little movement and has very good dimensional stability. Please note that all wood is liable to move when in service plus there can be dimensional change. The extent of this will depend on; the stability of the species itself, the conditions it is exposed to, the coating, decoration and protection.

Ayan is a hard and dense wood with medium bending strength. Compression strength is good along the grain and high crushing strength. It has with low stiffness and shock resistance. Severe blunting on tools can occur and a certain resistance to cutting due to silica in the wood. Saw blades can become clogged. A good finish can be obtained if the surface is pre-filled. Nailing and screwing requires pre-drilling. Glues very well. Ayan is not suitable for areas like kitchens, because the yellow dye in the pores is soluble in water, which result in staining.

Commonly asked questions about Ayan Wood
Is Ayan a hardwood or a softwood? Ayan is a hardwood. It is the same for; is Ayan hardwood or softwood? - Ayan is a hardwood.
Most groups/families of species share the same characteristics but this normally relates to their life as plants. Individual species do not always share the same characteristics as their relatives, in terms of the wood. Many factors influence how we use the wood and what we use it for, including where it grows, how it is forested, how it seasons/dries, etc. The answers to the following common questions, therefore relate to this particular species/wood and not the Ayan family as a whole. Even more specific – our answers relate to the wood (as we know it) in its form as a useable resource.
What colour is Ayan? Ayan can be described as light brown, yellow/brown
Is Ayan good for outdoor use? or is Ayan good for exterior use? Ayan is most suited for exterior/external use. Ayan can be used as an exterior/external timber (without treatment).
Whether the wood is naturally durable or not we would still recommend that it is decorated and/or coated with a suitable product to provide protection and/or maintain its appearance. This even applies when using the wood internally as, even subtle, changes in temperature or humidity will affect the wood. This will depend on the application/purpose of the wood and the user’s desired appearance. We also recommend that a recoating, care and maintenance programme is adhered to, for the life of an exterior wood. Wood cannot rot if it is kept dry – coatings and decoration can provide this protection. All of that said there are many durable timbers that are often left to weather naturally and will last for many years untreated/coated – movement and visual changes will occur but this is sometimes the desired effect. All wood is hygroscopic (it 'wants' to be in tune with its environment) it will therefore take on water from moisture in the air (or when directly exposed to or submerged in water) and ‘release it’ when dry or exposed to heat. This, inevitably, results in movement and dimensional change. For more about moisture in wood please click here - Moisture in wood
