Czech Silesian Larch is yellowish white, the core wood is reddish brown to dark reddish brown and further darkens. Typical features of Czech Silesian Larch include the tendency to resin clogging, which may occur during installation and after completion. However, using the OSMO product "Resin Removal Set" you can easily solve this small problem yourself. Larch is particularly sensitive to iron, and we recommend stainless steel fasteners only to prevent rust. As larch tends to cleft, all attachment points should be pre-drilled. We recommend using OSMO End Grain Sealing Wax No. 5735. Wood density: approx. 550 kg / m 3. Artificially dried to: 16-18%
