BK-TravertinoExterior&Interior is a precious mineral render intended for decorative protection of interior and exterior surfaces. It is characterized by excellent adhesion to mineral surfaces, exceptional water repellency, as well as, resistance to atmospheric influences and UV radiation. It provides high vapor permeability and excellent resistance to the development of microorganisms. BK-Travertino is produced exclusively in white color and subsequently is coated with a transparent BK-Velatura Exlusive coating, after drying for at least 24 hours under normal conditions.


The surface to which the render is applied must be fl at, dry, clean, free from loosely bonded parts, dust, water-soluble salts, grease and other impurities, which can prevent good adhesion to the substrate. Suitable substrates are cement-limemortars, reinforcement layer of thermal insulation systems, gypsum cardboards and cementfi ber boards. Before applying the decorative render coat the substrate with BK-Ultra Prime primer and in the case of smooth surfaces perform priming using the BK-Grund Universal. The preparation of the compound is done by adding the powder to about 25% of water to achieve a homogeneous mixture, without lumps ( 20kg of powder requires ~ 5l of water). Allow the compound to rest for at least 10-15 minutes, before stirring once more, and if necessary add water to adjust the consistency. Use prepared compound within 2 hours. BK-Travertino is applied in two coats with a stainless trowel. Apply the fi rst coat evenly in an approximate thickness of 1-2 mm. The second coat is applied after complete drying of the fi rst one (about 6 hours at normal drying). The creation of the texture of natural stone is achieved with the appropriate tool by which irregular recesses, characteristic of travertine stone, are created. The added eff ect of the render is achieved by lightly leveling with a metal trowel when the material begins to “pull”. When the material is surface-dried (about 2 hours when drying under normal conditions) it is possible to form the appearance of joints with the proper tool to imitate the look of stone blocks.
