Renosil Coarse

Finely levigating basic or intermediate coat in the BEECK RENOSIL system for heat insulation composite systems (WDVS) and synthetic resin-coated facades.

Field of application:
Filling primer coat with a structural grain size of 0.4 mm and a finely balanced granulometric curve. To be used as compensating basic and intermediate paint coat on synthetic resin plasters and weathered bearing old paint coats on dispersion basis. For heat-insulation composite systems (WDVS) only use brightened paint coats (lightness value HBZ > 40) to prevent heating up. Final coat in any case with BEECK Renosil fine of the same colour.

Handling:
Thoroughly mix with electrical stirrer before use. Thin with up to 10% BEECK Fixative, depending on the type of substrate, and apply with a roller or brush. Paint coherent surfaces evenly, quickly and seamlessly. Avoid visible roller edges, and drying spots, particularly around scaffolding; ensure sufficient personnel. Smoothly blend in the edges with the surface wet-on-wet. Ensure smooth and even grain distribution in the grazing light. Intermediate or final coat after 12 hours at the earliest. Final coat with BEECK Renosil fine in the same colour. Minimum handling temperature +5oC. Do not apply to heated-up surfaces, in wet conditions or in full sunshine. Adjacent surfaces, in particular windows, window sills and anodised surfaces must be protected from splashes - water glass is irreversibly etching e.g. for glass panes. Do a trial application of BEECK Renosil coarse on critical surfaces; apply a smoothing undercoat with BEECK Bonding coat fine/ coarse or BEECK Quartz filler, see substrate and pre-treatment.

Technical properties:
Quartz-grain silicate basic coat with good filling and covering capacities. Allows for permanent silicate facade protection also on less than perfect substrates. The COARSE product produces a particularly attractive stray light effect on smooth substrates and compensates structural defects. The surface is remineralised, moisture content and tendency to contamination is reduced.

Characteristics for water absorption and steam diffusion:

W24-value < 0.1 kg/(m2h1/2)
sd-value (H2O) approx. 0.07 m

Physical/Technical Characteristics:

Density approx. 1.45 - 1.6 g/cm3
PH value 11
VOC-content (Cat. A/c) max. 10 g/l

Colour:
White and factory-toned acc. to BEECK Colorsil. Can be individually toned with BEECK Renosil full colour. Final coat with BEECK Renosil fine in the same colour.

Drying:
Can be painted over after 12 hours, at the earliest. Protect fresh paint coats from rain and full sunshine; hang up scaffolding foil.

Consumption:
On smooth, regularly absorbent surfaces approx. 0.23 kg to 0.25 kg per paint coat and m2 . Define object-specific consumption by means of a trial application, particularly for rough substrates and levigating undercoats.

Available container sizes: 20 kg / 8 kg

Cleaning:
After use, immediately clean devices, tools and clothing with water.

Storage:
Usable for minimum 12 months if stored in a cool but frost-free place.

Composition:
Filled, ready-to-use silicate basis system, pigmented with light-fast mineral pigments. In addition to potassium water glass, recovered from water, quartz sand and potassium carbonate, it contains organic auxiliary products and binding agents with a proportion of ≥ 5%. Structural grain approx. 0.4 mm.

Substrate and pre-treatment:

General requirements:
The substrate must be clean, dry, solid and stable and free of efflorescence. For application on porous, both absorbent and repellent facades that may be organically bonded and must have at least partial mineral characteristics. Carefully correct any chippings, cracks and defective points with plaster corresponding to type and structure of the substrate; if required, use reinforcement mesh. Gently clean pressure-sensitive surfaces (WDVS); for algae-covered facades pre-treatment and after-treatment with BEECK Fungicide is required. On critical or mended surfaces or surfaces with hair cracks provide a full-surface undercoat with BEECK Bonding coat fine/coarse or BEECK Quartz filler, depending on requirement. Only apply BEECK Renosil coarse for levelling of minor structural defects as basic and/or intermediate coating. Final coat with BEECK Renosil fine.

Film-forming old paint coats, synthetic resin plasters, heat insulation composite systems (WDVS)

Cracked, weakly bonding old paint coats must be removed pore-deep, if possible. Check remaining paint for bonding and bearing capacities. Strongly bonding paint coats and plasters must be thoroughly cleaned, algae must be removed with BEECK Fungicide (see below). Prime absorbing and crumbly surfaces with BEECK MBA fixative, thinned with 2 parts water. BEECK Bonding coat fine and coarse can be applied as strongly bonding white basic coats. In case of hair cracks or minor structural defects, pre-paint the full surface of the facade with BEECK Quartz filler. Information on facade cleaning: Since synthetic resin plasters swell upon absorption of water and dry only slowly, sufficient intervals must be scheduled between cleaning and painting. Composite materials, insulation plasters and similarly pressure-sensitive surfaces must be gently cleaned to preserve the substrate.

Lime plaster (PI), lime-cement plaster (PII), cement plaster (PIII), concrete, fibre cement

Check new plaster for dryness and stability. Remove sinter layer from new plaster with BEECK Etching fluid. Prime strongly absorbing plaster with BEECK Fixative, thinned with 2 parts water. Plasters that are sanding on the surface but are otherwise stable must be repeatedly saturated with a mixture of 1 part Fixative and 5 parts water without leaving the layers to dry. Correct any chippings and defective spots according to type and structure of the substrate. Mended facades must be coated on the full surface with BEECK Quartz filler. Clean concrete pore-deep with a jet cleaner and formwork oil remover. Prime fibre cement with BEECK Silane primer and BEECK Bonding coat and do a trial application.

For defective substrates a different processing method is required. Substrates, such as air-hardening lime plaster, clay- containing or efflorescent surfaces as well as non-bearing old paint coats are not suitable for application of this product. Provide restoration plaster for efflorescence-exposed dado areas; pre-paint with BEECK Quartz filler.

Auxiliary products:
BEECK Etching fluid for removal of sinterskin from new plaster.
BEECK Fungicide against algae build-up. Apply in a saturating manner; clean the facade the next day either with a jet cleaner or another material-preserving method. For protection from re-infestation, after-treatment is recommended after completion of painting work. Determine efficiency on a sample surface that is exposed to long-term weathering.
BEECK Silane primer reduces moisture transport and salt efflorescence. BEECK Quartz filler, fibre-reinforced, levigating basic coat for covering of hair cracks and minor structural defects.
Full-surface application using a brush.
BEECK Bonding coat fine and coarse (0.4 mm), as white undercoat with excellent bonding properties.
