  • How do I finish DragonBoard +
    Dragonboard subflooring will accept almost all floorings from carpet to wood to resilient products such as luxury vinyl. DragonBoard decking works well with a wide range of waterproofing systems that allow foot traffic. In high impact walls, it can be finished similarly to drywall.
