INFORMATION

Vierosil Q is an exterior paint based on quartz, acrylic-siloxane resins, inorganic pigments, micronized fillers and special surface preservatives, which protect the coating from the formation of moss, algae and fungi. The product is applied in two layers, with an average consumption of approximately 0.25 lt/m2. It is suitable for use in the renovation of buildings located in historic urban centers and on plaster surfaces, cementitious wall surfaces, different mortars or equivalent, prefabricated cementitious elements, porous natural stones and surfaces already treated with other paints, after preparation, possible restoration with an anti-mold solution and subsequent application of Primer ACQ.

Preparation

  • To achieve maximum performance of Vierosil Q it is necessary to completely remove any pre-existing paint coating. Maximum water-repellent performance is achieved after 28 days of drying.
  • Local repair: for best results we recommend using a roller.
  • Ambient and substrate conditions:
    • Ambient application temperature: less than +5°C / more than +35°C
    • Relative humidity: < 80%
    • Substrate temperature: less than +5°C / more than +35°C
    • Do not apply to substrates exposed to direct sunlight or strong wind
  • Dilute the product with water 20% by volume for the first coat and 10% for the second. Dilute the product according to the instructions and mix until a homogeneous mixture is obtained.
  • New, mature, homogeneous, complete city wall surfaces:
    • Clean thoroughly, removing all traces of dust.
    • Make sure the wall is completely dry, apply a coat of Primer ACQ and wait 24 hours.
  • Wall surfaces made of lime, cement, plaster, already coated or partially degraded:
    • Synthetic paints and coatings: to make the most of the product’s breathability characteristics, it is recommended to completely remove old paints and synthetic coatings either with a special abrasive or with a pressure washer and water jet.
    • Mineral or absorbent paints and coatings: remove all traces of dirt, parts that are not completely adhered and any frayed areas.
  • Fill and smooth with compatible products and let dry. Make sure the wall is completely dry and apply a coat of Primer ACQ and wait 24 hours.
  • If there are traces of mold or moss, first apply a mold and moss cleaning solution.
