MARBRO MURO:

• One of a family of thick plastic coatings (DTU 59.2)
• An ornamental coating based on natural marble granules for interiors and exteriors.
• Ready to use product (with addition of water -2 to 3%) which can be applied simply and rapidly.
• Product exists in 48 basic colors, perfectly adapted to the environment of the region.

COMPOSITION

• A resin in aqueous dispersion.
• Marble granulate, naturally tinted.
• Specific additives to ensure good stability and effective application of the coating as a paste.

USAGE

The product is a decorative coating for individual, collective, industrial or tertiary buildings, for either exterior or interior application.  Aside from the wall surfaces mentioned above, the product is also perfectly adapted for use on window sills, lintels, loggias and support beams.

ALLOWABLE SUPPORTS

Exterior supports:

• Cast concrete (DTU 23.1) with a powder mortar (Planimur, Planidress, Monocouches).
• Masonry for elements in conformity with DTU 20.1, covered with a waterproof coating following DTU 26.1 or with a grey monolayer coating under CSTB certification.
• Old supports: consult PB technical services.

Interior supports:

• The supports mentioned above.
• Plaster coatings, cardboard plasterboards, plaster tiles, etc.
• Masonry or concrete wall panels.

SUPPORTS TO AVOID

• Supports exposed to damage by humidity through capillarity (sub-foundations).
• horizontal or sloping (inclined less than 45%) exposed to rain (window supports, balconies).

APPLICATION

• Use at a temperature between +5C and +30C
• Avoid applications on supports that are frozen, freezing, or thawing or if there is a risk of frost in the next 24 hours.
• Avoid application at high temperatures and humidity or in strong winds.
• Apply product only on dry supports.  Otherwise because of the extended drying time, air bubbles may appear between the coating and the supports.
• Apply in equal thicknesses, not exceeding 2 grains.  Avoid excessive thicknesses during application.
• For supports covered with a coating or waterproof paint, consult the NFP 84404-1 referenced in DUT 42-1 annex B, which indicates the required removal process or the treatment of the coating already in place.  If the organic coating is to be maintained, apply the Marbro Muro under ideal climatic conditions, followed by a long period of dry weather and after a treatment that can ensure the effectiveness of the required under-layer of absorption (DTU 59-2, 4.22).
• Protection of vertical surfaces.
• The upper angles of vertical surfaces must be given the appropriate construction treatments, in conformity with the initial design, for example: ledges, skirts or drips, so that rainwater does not run into the adhesive surface of the coating.
