Rystix Sales is privileged in having close and mutually respected working relationships with organisations like the South African Bureau of Standards, the CSIR, the Hans Merensky Foundation and the South African Wood Preservative Association To verify its superiority Rystix submitted the exterior sealer to the Council for Scientific & Industrial Research and contracted them to run an accelerated weathering test comparing it to four of the leading locally made competitive products plus the leading imported product Flowing from this positive test result, Rystix Timbacare has been successfully marketed to many of the leading timber log home and deck builders in South Africa since late 1993
