NATURAL BOND

Coloured three-component render with rough texture for polished plaster coatings in the NATURAL range

Description

NATURAL BOND is a three component product made up of:

  • component A: aqueous dispersion of liquid epoxy pre-polymers, additives and special fillers;
  • component B: aqueous dispersion of co-polymerisation polyamines and additives;
  • component C: cementitious powder and silica-quartz sands.

NATURAL BOND is specifically designed to realize the bottom layers with a Venetian Plaster Effect in the NATURAL range.

NATURAL BOND is available in two versions:

  • COLORATO: with pre-pigmented component A;
  • COLORABILE: with pigment-free component A, that must be coloured with the mixtures belonging to the NORDRESINE “SISTEMA TINTOMETRICO” water based range.
Usage field

Specific preparation

Coloured base layer for polished plaster coatings in polymer-cement for private and commercial buildings.

 Surface preparation

NATURAL BOND shall be used on surfaces previously treated with primer.

NATURAL BOND is usually applied on surfaces treated with NATURAL FONDO, which allow the restoration of any surface imperfection, in particular when application over tiles and natural stones is required.

For vertical surfaces and furniture sector application, the surface can be treated with a layer of NORPHEN FONDO SL followed by a light quartz sand 0.1-0.6 broadcast.

Product preparation

NATURAL BOND COLORATO:

  • pour NATURAL BOND comp. B into comp. A and mix well with a professional blender at low rpm;
  • pour comp. C into the mixture that has formed and stir well until a completely homogeneous dough is obtained.

 

NATURAL BOND COLORABILE:

  • based on the colour selected, weigh and pour the NORDRESINE “SISTEMA TINTOMETRICO” water based range pastes into the NATURAL BOND COLORABILE comp. A container, or use the pre-weighed pigments in the NATURAL COLOR range
  • homogenize the coloured comp. A so obtained;
  • pour NATURAL BOND comp. B into comp. A and mix well with a professional blender at low rpm;
  • pour comp. C into the so obtained mixture and stir well until a completely homogeneous mixture is achieved.

 

Leave the mixture to rest for 3-4 minutes and then apply with a steel plastering trowel:

  • for large areas on the floor the ideal plastering trowel is 48 x 10 cm (MOD.TED 814-02) or similar;
  • for large vertical surfaces, as above or 28 x 12 cm (MOD. AM 845/S 87);
  • for small areas or uneven surfaces, 20 x 8 cm (MOD. NR 841-603).
Product application
  • Apply the product in a smooth layer, keeping the plastering trowel at an angle of approximately 10° from the surface.

    When smoothed properly, one coat should be sufficient.

    If required, a second coat can be applied as soon as the first coat can be walked on, or as soon as the product has hardened on walls.

    Once dry, which may take 4-5 hours (at 20°C) based on environmental conditions, the surface can be sanded with a 120 grade abrasive mesh and vacuumed.
Tool cleaning

If the product is fresh, tools should be cleaned with water; if the product has hardened, it must be mechanically removed.

Average Consumption

Tiled surfaces with wide and deep joints (such as Tuscan terracotta) require a second coat of NATURAL BOND once the first coat has hardened (4-5 hours at 20°C), for a total coverage of approx. 1.10-1.15 kg/m2 for two coats.
