Special white skim coat with high workability, thixotropy, plasticity and elasticity, breathable, very low in volatile organic compounds and fully recyclable at end of life, based on FL B 3.5 lime (CL65 Q35) compliant with UNI EN 459-1, pure selected aggregates and additives, suitable for:
- skim coating new indoor or outdoor plaster before painting, mineral finishing, tiling or wallpapering;
- skim coating existing plaster, especially on protected or listed buildings, outdoors or indoors, after removing old paint or the old finishing coat;
- skim coating existing plaster, especially on protected or listed buildings, left uneven after removing the old finishing coat or mineral finish;
- skim coating radiant wall heating systems that require thin layers of mortar;
- partial patching or full replacement of plaster less than 10 mm thick;
- leveling or smoothing skim coats on walls or ceilings, 3 to 30 mm thick;

Rasante K FL has very low plastic shrinkage, bonds excellently to the substrate even when smooth and poorly absorbent, and offers excellent abrasion resistance and high durability against the weather. It is highly breathable and hygroscopic, does not form a vapor barrier, has a low content of water-soluble salts and a very low content of volatile organic compounds (VOC), contains no solvents or substances harmful to health and is fully recyclable at end of life.
Rasante K FL is available in two versions, depending on the maximum aggregate size:
- fine version (type 08), with a maximum grain size of 0.8 mm;
- extra-fine version (type 04), with a maximum grain size of 0.4 mm.
Key features:
- very low VOC content and class A+ under the French VOC – CMR Regulation;
- high elasticity and ease of application, not rigid;
- highly durable outdoors;
- very low content of water-soluble salts;
- contains no cement;
- contains no solvents or substances harmful to health;

Rasante K FL is used to even out or level masonry or mixed plasters with different water absorption using a single product, in a single coat. It is particularly suitable for historic or listed buildings.
As a plaster: Rasante K FL fine (type 08) can be applied up to 30 mm thick on solid brick, brick, concrete block, wood-cement, aerated concrete or tuff masonry, or on existing hydraulic binder plasters, even uneven ones, with or without paint or mineral finish, provided they are sound, clean and well bonded to the wall.
As a skim coat: Rasante K FL fine and extra-fine (type 08 and type 04) can be applied at least 2-3 mm thick on existing plasters with or without paint or mineral finish, provided they are based on hydraulic binders, sound, dust-free and well bonded to the wall, and in general on any substrate whose low water absorption and low roughness can cause poor adhesion with ordinary mortars.
Rasante K FL can be used for skim coats reinforced with glass fiber mesh and is compatible with radiant wall heating systems.
Rasante K FL can be painted with lime, silicate, siloxane or acrylic paints, or finished with white or through-colored mineral finishes in powder or paste form, preferably vapor-permeable. It is compatible with wallpaper and with ceramic or stone wall tiles.
