Celtis D Afrique
Species profile
The wood is cream white to light yellow bordering on light brown. Unpleasant odour when green or with rewetted wood. It does not have demarcated sapwood. The grain is straight or interlocked and the texture is medium.

The blunting effect is fairly high and peeling and slicing is reported to be good. Possible difficulties with highly interlocked grain; in this case, special tools are recommended. Sometimes, high silica content for C. tessmannii. Nailing is good but pre-boring is necessary. Tends to split in nailing. Gluing is correct. Celtis dries slowly. Defects can be reduced by top weighting the piles and applying end-coating products. Drying must be done slowly and carefully. Hardness varies from fairly hard to hard.

Celtis is not durable to fungi and is susceptible to dry wood borers; sapwood not or slightly demarcated (risk in all the wood). Prone to blue stain.

Celtis can be used for several applications such as:
• interior: e.g. panelling, veneer, boxes and crates, furniture, stairs, formwork, flooring, joinery, moulding, matches, sliced veneer
• exterior: e.g. heavy carpentry, vehicle or container flooring

Sawdust may be irritant (Ohia)
