HR PROF (also sold as Holz Prof) is a water based, ready to use fire retardant treatment for wood and other porous combustible building materials. It penetrates into the substrate rather than forming a surface film, and is supplied colourless and odourless so the appearance and texture of the timber are retained.
It is solvent free, non-hazardous in use and has anti-fungicidal properties. No separate protective finishing coat is required, although compatible stains, varnishes and some paints can be applied over it. Typical uses include timber frame buildings, external cladding, staircases, trusses, doors, joists, floors, walls, stables, log cabins, fencing and garages.
