10th June 2022 Can I use VJ Board Pro in bathrooms? We don’t recommend using VJ Board in wet areas or areas exposed to a lot of moisture, such as bathrooms. MDF products don’t expand or contract like real wood does, meaning that it’s more susceptible to moisture damage if water is allowed to penetrate the surface (as is commonplace in a bathroom). All our VJ sheets are standard MRMDF. There are many other products appropriate for use in the bathroom such as Intrims range of Lining Boards, which when run vertically provide the VJ Board appearance. You can use H3-treated pine LB03 or LB06 Intrim Lining Boards.
