Advantages of Full-Surface Gluing Full-surface gluing is one of the best installation methods when looking for a durable, stable, and long-lasting flooring solution. This method involves gluing the entire surface of the floorboards to the subfloor, providing several benefits: Increased stability and durability Reduced footstep and impact noise Ideal for underfloor heating as it ensures faster heat transfer No need for expansion joints between rooms   Finishing of Floorboards Floorboards Oak Mix come with a factory-brushed surface, so no additional sanding is required after installation. Knots and cracks are pre-filled and sanded in the factory. After gluing the floorboards, they can be finished with lacquer, oil, or hardwax oil in the desired shade. It is also possible to order factory-finished floorboards for an additional cost.
