Description
¤Description
RASOCHIM FIBER is a fibre-reinforced cement premix
single-component gray powder to set and ad
quick drying, composed of special cements, fibers
synthetic and silica sands of selected granulometry.
RASOCHIM FIBER can only be used indoors.
By mixing RASOCHIM FIBER with water a paste is obtained
sliding cementitious suitable for smoothing
self-levelling high-strength and quick-maturing substrates
old and new. RASOCHIM FIBER is applied in thicknesses up to 10
mm per coat on sand and cement screeds or ready-to-use screeds,
primed anhydrite screeds, existing ceramic floors,
tiles, natural stones, clinker and stoneware.

¤Laying conditions
◊ Type of fund
Sand and cement screeds or ready-to-use screeds without any
priming, primed anhydrite screeds, floors
existing ceramic tiles, tiles, natural stones, clinker and stoneware.
◊ Status of the fund
Make sure that the substrates are dry, solid, free from dust,
removable parts, varnishes, waxes, oils, rust and traces of chalk.
Inadequately solid cementitious substrates must
be removed or, where possible, consolidated using
PRYMER W 30 K (see relative technical data sheet).
Dusty or very porous cement substrates must
be treated with PRYMER W (see relative technical data sheet)
or CHIMIGRIP diluted 50% with water (see relevant sheet
technique) in order to fix the powder.
Non-absorbent surfaces: apply CHIMIGRIP (see relative
technical data sheet) after cleaning with DILUENTE ACETONE or with
appropriate cleaners or wax removers.
Moist absorbent cementitious substrates must be
primed with PRYMER SF 1105 or PRYMER PUB 77 (see
relative technical data sheets) and subsequently quartzed.
Damp non-absorbent substrates should be treated with
PRYMER EPOX WETT or PRYMER WB 328 S (see related
data sheets) and subsequently quartzed.
Anhydrite screeds must be primed with PRYMER
W (see relative technical sheet) before they can be levelled
with RASOCHIM FIBER.
¤How to use
Dough preparation
Mix a 25 kg bag of RASOCHIM FIBER into the following
method: pour the required amount of water indicated in the item
"Mix ratio" into a clean bowl and add
powder gradually, mixing with a hand mixer, a
low number of revolutions, until obtaining a smooth, homogeneous mortar
and free of lumps; after 2-3 minutes, stir briefly:
the dough is ready for use.
The amount of RASOCHIM FIBER mixed each time must be
the one needed to be used within 45 minutes (at
temperature of +20°C). The residual moisture measurement must
only be carried out with a carbide hygrometer tool.
Applying the mix
Pour RASOCHIM FIBER on the substrate in a single coat
up to 10 mm by vigorously pressing with a spatula
American, squeegee or trowel to improve adhesion to the substrate
and then adjust the thickness. To improve adhesion and
therefore the thickness, any imperfections from troweling will be
eliminated by the self-levelling effect characteristic of the product.
If more coats are required, it is recommended to apply
RASOCHIM FIBER in rapid sequence (about 20-30 minutes a
depending on the temperature and the degree of absorption of the
background). After 24 hours, wooden floors can be applied
and resilient.
In the case of very large surfaces, respect all joints
existing expansion joints in the substrate, create joints
split every 50 m² approximately.
