Description

DESCRIPTION

  Rustic plaster with old walls appearance, used in the finishing work of the building. Interior decorative plaster which can be used on any sound support to decorate and finish

  interior walls of houses and constructions.

  * Micronized marble powder 5 to 10% * Plaster of Paris 50 to 60% * White cement 25 to 30% * Vermex (vermiculite) 1.5 to 2.5% * Rhône Poulenc bonding resin "Rhoximat Pav 22" 2 at 4% * Natural oxides or ochres according to colors 1 to 10% Product for covering interior walls and partitions of houses, giving the appearance of walls painted with lime, but

  with long-lasting durability and incomparable hardness.

  This product is characterized by the possibility of searching for different materials and aspects depending on the desired effect

by the user.

  This product does not necessarily require a setting

  work by a professional, by its ease of application.

  This product can be dosed in dyes almost infinitely. CAUTION: It is not a painting; it is not possible, with old-style rustic plaster, to obtain a uniform and constant color or material effect. By definition, rustic rendering gives nuanced, sometimes even extreme, effects in the same color. The effect obtained depends on both the support and the applicator. COMPOSITION: Natural mineral bases with different particle sizes and densities. The dyes of the rustic coating are ochres or oxides. Colors are not constant, it may

there are slight variations.

  APPLICATION ON ALL HEALTHY SUBSTRATES: Such as plaster, cement,

  plasterboard, honeycomb concrete, plaster tiles.

  The support must be dry, clean, porous, free of grease,

oil or varnish.

  On agglomerated or plywood, inert or rigid, as well as on old paints and fatty plasters, it is

  recommended to do an undercoat paint.

  The coating is not flexible. It is not suitable for hinged or sliding doors, as well as any flexible support. Doubtful support necessarily leads to delamination in the long term. On walls of variable composition such as plaster, wood, old paint, traces of cracks, fittings, plaster tiles and / or siporex, the printing of the wall is mandatory, There are risks of finding the drawings under the coating and

  traces of the different zones, or joints of panels or slabs.

  The undercoat paint neutralizes these undesirable effects.

  The coating applies to the trowel, the spatula or the trowel

  with blunt edges, depending on the desired finish.

  In one application, spread the mixture a little

  irregular without wanting to smooth it out on the first pass.

  People who want an "old wall" look let it dry without smoothing. For those who want a smooth appearance, let the product harden for 10 to 15 minutes depending on the temperature, then smooth to dry for a partially uniform effect,

wetting for a nuance effect.

  Depending on the medium, one to two applications are required. On very porous substrates, the first application should be a little more liquid; it is possible to go back to the first pass for a second application without waiting for complete drying, just after hardening. Another application is also possible, several days after the first or the

second application.

  For inexperienced people, it is advisable to give it a try and let it dry for a few days in order to see the final color. Avoid crossed, vertical and horizontal layers. This product is not a smoothing or filler, nor is any underlayment or paint. The effects are in the material. Avoid tiring the product, apply a layer of sufficient thickness. Do not crush it to

  make a paste as for a greasy or smoothing coating.

  Rustic plaster is a simple product that does not need to be reworked. It is possible to smooth the second application, but in all cases, attempts to define and confirm the colors are desirable before undertaking any

important sites.

  THICKNESS: From 1 to 3 mm on average. However, the coating makes it possible to make up for unevenness and to fill in cracks ranging

  from 10 to 15 mm before the first application.

  WORK: 30 min, once mixed with water. Avoid

  add water to lengthen the product at the end of the bowl.

  DRYING: On very porous substrates, rustic plaster is

hard in an hour.

  The coating is considered dry only after taking its final color, i.e. between 2 and 4 days, depending on the porosity of the support, the temperature, and, or, the humidity of the

  room; however, on printed walls, drying is slower.

  CONSUMPTION: 15 liters of dry product cover 10 to 12 m2 (average consumption for standardized support) depending on the desired thickness, the condition of the walls and the skill of the applicator. FINISHING: Once dry, the rustic coating can be varnished, waxed, polished, patinated; all patina techniques are possible, it can also be waterproofed. Pass

the vacuum cleaner before any treatment.

  For any finish and any treatment, it is imperative

  the plaster is absolutely dry and free of dust.

  COLORS, SHADES, VARIATIONS: The product has been designed to render an old, non-uniform, nuanced or very nuanced wall effect. PROPERTIES: The product is non-flammable, has no known incompatibility with polystyrene or insulators. he

  exhibits good resistance to humidity migrations.

  PRECAUTIONS: Rustic plaster should not be applied in cold weather, or on damp or oily substrates (the temperature of

  air and wall must be greater than 5 C).

  COLORS: 12 basic colors and derivatives - 1) Vine black - 7) Havana 2) Red ocher - 8) Yellow oxide 63 - 3) Red oxide 83 - 9) Ecru - Stone tone - 4) Light green oxide - 10) Titanium white oxide - 5) Green earth 11) Burnt shade - 6) Ultramarine blue - 12) Natural sienna

  Special colors are possible.

  Note: - The drying time must be respected before being able to judge the final color, and before any treatment, waterproofing, wax or patina etc ... - In case of marking of old woodwork or traces of plaster tile joints

  or siporex, iron one layer after the wall has completely dried.

  In all cases, use for variable supports, the

undercoat paint.
