ProBor 50 is a ready-for-use wood preservative paste based on boron, a naturally occurring mineral with a long history of use. It is supplied in a 310ml cartridge for use with a standard mastic gun. ProBor 50 is designed to be injected into timber or masonry. It can also be applied to the surface of timber, although it should be noted that a white deposit will be left.
