Lime-based trowel coating with marble powder for interiors and exteriors
Marmur Medio is a lime-based finishing plaster coat, made of wellseasoned hydrated putty, fine marbles and rheological modifiers, which guarantee a perfect workability of the product.
With its formulation, Marmur Medio permits to achieve “cloudy” esthetic effects, with soft and vibrant shades. Thanks to its versatility, Marmur Medio permits to get several textures, depending on the application techniques.
Marmur Medio is indicated for the decoration of prestigious exterior and interior surfaces. Natural lime plasters represent Marmur Medio’s most suitable substrate, since the product reacts chemically with them, building up a unique “body” able to preserve the lime coating for a longer period of time.
Application:
- The substrate must be perfectly dry, dust-free, with no humidity and salt stains. Resurface or consolidate the surface with specific products if necessary.
- In case of mould, treat the surface with suitable specific products.
- Brush or remove any efflorescence and old peeling paint. Higher layers of old lime-based paint and tempera paint must be removed. Brush out dust, smog or other deposits before the application.
- In case of non-homogeneous or chalky surfaces, apply one layer of Decofix (micronized wall sealer) diluted, with a brush.
- Over dry and compact substrates, apply one layer of Novaprimer (water-based acrylic pigmented primer), diluted, with a brush.
- On dry surface, apply one smooth coat of Marmur Medio with a stainless steel trowel. Before it dries out, work the surface with a wet sponge trowel. Remove any imperfections and over-product.
- Wait the complete drying of the surface, then apply a second coat of Marmur Medio with stainless steel trowel and, before it completely dries, finish off the surface with a wet sponge trowel, obtaining a compact and rough surface at the same time.
- In order to obtain a semi-polished and compact effect, work the surface still wet with a stainless steel trowel.
- To improve the visual and tactile effect, it is recommended to keep the surface wet, compacting it until obtaining the desired effect.
- Different textures can be reach using specific tools and/or applying, after at least 24 hours, one or more coats of Antiche Patine, siloxane colour wash, properly diluted.
May also be applied over:
- Plaster and cement mortars
- Pre-mixed renderings
- Pre-existing lime and gypsum plasters
- Moisture-permeable plasters
- Gypsum plaster-boards.
Approximate coverage yields 2-2.5 Kg/m2 in two coats, depending on the substrate and its absorption rate.
