The use of wood for construction is not new, however, in some countries there are many resistances to its use, due mainly to the behaviour of wood during a fire. This study aimed to enhance the fire resistance of wood by treating the wood with Kraft lignin emulsion. An emulsion from Kraft lignin was used for the treatment of wood Pinus sp. by full cell methods. The specific mass, wettability and Brinell hardness were analysed. Fire resistances were determined (ignition, flame and ember time). The obtained results showed that the ignition times of treated wood, were higher than those of untreated wood. The emulsion hinders the ignition of samples in approximately 10 seconds. Conversely, the flame and ember time was significantly longer in wood treated, but there was a lower mass loss, compared to untreated wood. This shows that the treatment improves the behaviour of wood in relation to the ignition of fire and also increases the hardness of the wood. Wettability analysis was possible to observe that treatment reduces the rate of moisture uptake.
