USE

CHARACTERISTICS

PACKAGE

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 Exclusive coating, after drying for at least 24 hours under normal conditions.

Preparation and application :

The surface to which the render is applied must be flat, 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-lime mortars, reinforcement layer of thermal insulation systems, gypsum cardboards, and cement-fiber boards. Before applying the decorative render, coat the substrate with BK-Ultra Prime primer, and for smooth surfaces, perform priming using BK-Grund Universal. Prepare the compound by adding the powder to about 25% water to achieve a homogeneous mixture without lumps (~5L of water for 20kg powder). Allow the compound to rest for 10-15 minutes before stirring again and adjust the consistency with water if necessary. Use the prepared compound within 2 hours. Apply BK-Travertino in two coats with a stainless trowel: first coat at a thickness of 1-2 mm, and apply the second coat after the first one dries completely (about 6 hours under normal conditions). Achieve the natural stone texture with an appropriate tool, creating irregular recesses characteristic of travertine stone. Additional effects can be achieved by leveling with a metal trowel when the material begins to "pull." After about 2 hours (under normal drying), joint lines can be created with a tool to imitate stone block appearance. See product datasheet for more detailed instructions.

Application temperature :

The air and substrate temperatures during installation should be in the range from +5 °C to +30 °C. Do not work under direct sunlight, fog, wind or rain.

Consumption :

Approximately 2.5-2.7 kg/m², depending on technique and thickness of application.

Shelf life and storage :

18 months in original sealed packing. Store at +5°C to +25°C, in a dry and well-ventilated room. The production date is printed on the packaging.
