Check out our installation video to see the fitting process. Our beadboard panels 1500mm high come in a pack of 5 and will cover 1.95 linear metres, each panel is 390mm wide plus a 10mm lapped halved joint that is hidden in the groove. The beadboard is made from 9mm moisture resistant mdf so it's suitable for environments like bathrooms and kitchens where moisture is present but it's not waterproof and should not be in direct contact with water. Each groove is 130mm apart centre to centre, the grooves have a double V groove with a bead in the middle. The panels are unfinished but are available primed white and sanded, after priming the panels will need an undercoat and finish coat of paint, the beadboard can be placed directly to the wall using wall adhesive and fixings. Top trims are sold separately.
