Cemintel Barestone prefinished panels are extremely popular for a raw, contemporary finish to many internal applications.
Barestone is available in four colours – Original, Ash, Lunar and Graphite. Ash, Lunar and Graphite add colour depth while maintaining the raw, natural appeal of the much-loved Original.
The panels have a stain resistant coating applied and are simply installed internally with either split battens, adhering to timber battens, and for a more industrial look, exposed fixing.
** Internal Samples will be available in August**
