Yes. Treatment to hazard class 3 (H3.2) is recommended for all Glulam beams exposed to the weather. Along with this treatment, an exterior adhesive such as resorcinol adhesive should be used. The finished beams must be suitably coated & maintained with either a penetrating sealer or paint coating. When painting or staining external TimberLab Glulam beams it is preferable to use lighter colours. Dark colours attract heat and may cause surface shrinkage. Because TimberLab Glulam is chemically inert, it is ideally suited to corrosive atmospheres such as marine structures, fertilisers and scouring plants; where steel is subject to rust and corrosion.
