Coloured tri-component render with fine texture for polished plaster coatings in the NATURAL range

Description

NATURAL TOP 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 TOP  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.

Specific preparation

NATURAL TOP viene usato su superfici preparate con NATURAL BOND.

Product preparation

NATURAL TOP 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 TOP COLORABILE:

  • based on the colour selected, weigh and pour the NORDRESINE “SISTEMA TINTOMETRICO” water based range pastes into the NATURAL TOP COLORABILE comp. A container, or use the pre-weighed pigments in the NATURAL COLOR range
  • homogenize the coloured comp. A so obtained;
  • pour NATURAL TOP 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 white-plastic trowel:

  • for large areas on the floor or walls the ideal trowel is 48 x 14 cm (MOD.PLA 817/RB-36) or  similar;
  • for small areas or to obtain colour effect the ideal trowel is 28 x 13 cm (MOD.PLA 817/RS-33) or similar;
Product application

Apply the product in a smooth layer, keeping the plastering trowel at an angle of approximately 10° from the surface.

At least two coats should be applied, with 3 or more hours between coats based on environmental conditions.

Once the first coat has dried (optional) sand with a grade 120 abrasive and vacuum.

If the end result of the job complies with the plan, it can be finished by sanding with a grade 180 abrasive mesh (for best results use a partially used abrasive mesh).

If necessary in order to achieve an even smoother surface, a further thin coat can be applied and then sanded as above.

The end result of the job is a floor:

• NATURAL CROMO

achieved using:

  • 1 coat of NATURAL BOND
  • 2 coats of NATURAL TOP

Application can be continued based on the desired finish:

• NATURAL with ALIZEE finish

achieved using:

  • 1 coat of NATURAL BOND
  • 2 coats of NATURAL TOP
  • 3rd coat:
  • prepare NATURAL TOP (A+B+C) in a darker shade, or in any case a different shade, to the base layer (first 2 coats), apply with a 28 cm white plastic spatula (MOD. PLA 817/RS-33); the application technique for the finishing coat consists of "applying and removing" the product to create areas that are thicker with product and others that are thinner.
  • Wait 12 hours and sand with a grade 180 abrasive, taking care to remove more product where needed in order to create the ALIZEE cloudy effect.

• NATURAL with EVIDENCE finish achieved using:

  • 1 coat of NATURAL BOND
  • 2 coats of NATURAL TOP
  • 3 rd coat:
    • prepare NATURAL TOP (A+B+C) in a darker shade, or in any case a different shade, to the base layer (first 2 coats), apply with a 28 cm white plastic spatula (MOD. PLA 817/RS-33). The application technique for the finishing coat consists of "applying and removing" the product to create areas that are thicker with product and others that are thinner, with greater differences in thickness with respect to the technique used for ALISEE, in order to create the EVIDENCE effect.
    • Wait 12 hours and sand with a grade 180 abrasive to remove the areas that are excessively thick.

 

Product finishing

Apply NATURAL COAT PRIMER following the instruction of the product TDS, followed by NATURAL COAT LUX or NATURAL COAT MAT.
