Abstract We reported in a previous study that wood fiber orthogonal grooving improves flame retardant vacuum-pressure impregnation performance. However, it was limited to small sample sizes. extended our investigate the effect of on Japanese cedar ( Cryptomeria japonica D. Don.) and Korean larch Larix kaempferi (Lamb.) Carriere) full-size timber [2,400 mm(L) × 100 mm(W) 22 mm(T)], which are widely used as building interior lining. had higher open-pore porosity gas permeability than larch. As result, no significant difficulty impregnating retardant, even without pretreatment process. The retardant's performance control insignificant, but ability improved after grooving. In conclusion, can meet fire safety standards announced by Ministry Land, Infrastructure Transport groove processing before impregnation. On other hand, be impregnated with direction achieve this is simple practical technique immediately impervious commercial wood.
