Vierosil ASX 1.0/1.2/1.5mm is a trowel plaster with a full and fibrous coating structure, for external and internal wall surfaces. Water-based product with Siloxane and Acrylic copolymers, colored oxides, marble chips and special additives. The type of binder used gives the product high resistance to alkalis and atmospheric agents, excellent applicability, workability and remarkable adhesion. The adoption of solid pigments very resistant to light and alkalis ensures the stability of the colors even in masonry that is particularly exposed to light radiation and bad weather conditions.

Due to its characteristics, it is suitable for use as a final coating in VIEROCLIMA External Thermal Insulation systems.

INFORMATION

Vierosil ASX 1.0/1.2/1.5mm is a trowel plaster with a full and fibrous coating structure, for external and internal wall surfaces. Water-based product with Siloxane and Acrylic copolymers, colored oxides, marble chips and special additives. The type of binder used gives the product high resistance to alkalis and atmospheric agents, excellent applicability, workability and remarkable adhesion. The adoption of solid pigments very resistant to light and alkalis ensures the stability of the colors even in masonry that is particularly exposed to light radiation and bad weather conditions.

Due to its characteristics, it is suitable for use as a final coating in VIEROCLIMA External Thermal Insulation systems.

Preparation

  • New, mature, homogeneous, urban wall surfaces: Clean thoroughly, removing all traces of dust. Make sure the wall is completely dry, apply a coat of PRYMER ACQ acrylic primer and wait 6 hours.
  • Cementitious wall surfaces, already coated or partially deteriorated:
    • Painted surface: remove all traces of dirt or stains, parts that are not completely adhered and any frayed parts.
    • Surface with many old layers: remove the old layers with an abrasive and wash the surface with a water pressure washer. In case of extensive moss or mold, clean first with the anti-mold solution. Apply layers up to 5 mm thick with ADESAN G5 WHITE or GREY cementitious leveling mortar, after unifying the surface by applying a layer of PRYMER ACQ 100 primer and leave to harden for at least 5-6 days. Thicker areas should be treated with materials compatible with the existing cementitious mortar and left to harden. Make sure the wall is completely dry and prime the entire surface with a layer of PRYMER ACQ 100 primer. If necessary, apply another layer to the entire surface with ADESAN G5 WHITE or GREY cementitious leveling mortar, complete the application and leave to dry.
    • Wall surfaces with external thermal insulation system: After hardening of the reinforced Glue-Mesh system, proceed with the application of a layer of the stabilizing primer PRYMER PGM (alternatively you can use AKROSIL A acrylic siloxane insulating primer or the acrylic Nanotechnology primer PRYMER ACQ 100).

Note: The combination of PRYMER PGM and the colored finishing plaster Vierosil ASX 1.0/1.2/1.5mm is part of the VIEROCLIMA PV system, which enjoys the technical assessment of the European Organization for Technical Assessment (EOTA). For proper installation, it is recommended to follow the instructions given in the “Vieroclima Installation Manual”.

 

Application
  • Do not apply to masonry exposed to intense sunlight during application or in ambient temperature conditions where the substrate may reach below + 5ºC or above + 35°C in the first 24 hours after application. The relative humidity must not exceed 70%.
  • Apply to homogeneous substrates. In the case of very large surfaces, provide suitable breaks near gutters or gutters or create expansion joints.
  • After application, the surfaces must be protected from possible rain for at least 48 hours.
  • The product is generally ready for use.
  • Depending on the needs (climatic conditions, type of treatment) it can be diluted with a maximum of 1% water (equivalent to a glass of water for a 25 kg package).
  • Mix well until a homogeneous mass is obtained and apply a layer with a stainless steel top handle spatula. Then work the material with a plastic trowel and before it starts to dry, spread it with the same tool.
  • The product completes the drying and polymerization processes within 8 – 10 days in good environmental conditions (+5°C / +35°C, Humidity max. 85%). If the product, during this period, is washed away by rainwater, unsightly marks and runs with a translucent and sticky appearance may appear. This phenomenon, of a temporary nature, does not affect the quality characteristics of the product and can be easily eliminated by washing with water or by waiting for the next rain.
