Abstract: In this study, changes in combustion properties in solid wood treated with different chemicals and varnishes were investigated. Wood samples prepared from Scotch pine ( Pinus sylvestris L.) and chestnut ( Castanea sativa Mill.) were impregnated with tanalith-CBC, water repellent (WR) solutions + synthetic varnish and WR + polyurethane varnish. Afterwards, synthetic and polyurethane varnishes were applied to the surfaces. Varnishing had the initial effect of fire retardation in both Scotch pine and chestnut impregnated with tanalith-CBS. Loss of weight was found to be 20% in chestnut samples and 13% in Scotch pine samples. However, varnishes did not affect combustion properties after the impregnation proccess. The split result of combustion did not occur in samples impregnated with tanalith-CBS samples.
