Loira

Finish mineral coating, grain size 0,3mm and 0,6mm

Mineral coating composed by selected granulometry inerts, specific addictives and UV stable pigments, base on cured lime EN 459-1 certified. Features excellent vapor permeability, ideal for the realization of highly breathable velvet finishes. It allows to replicate from a physical, chemical and mineral composition point of view the properties of the original mortars found in buildings of historical and artistic interest.

Available in two granulometries:

  • 0,3mm
  • 0,6mm


Information

Fields of application

Recommended for the realization of fine texture intonachino, for indoor and outdoor , on:

  • Old and new plasters based on hydraulic lime
  • De-humidifing, macroporous substrate plasters
  • Lime/cement based plasters

 

Support preparation

Substrates must be completely cured. Remove dust, efflorescences, dirt and oil traces from surfaces. To level and even the support absorption, it is recommended to apply a mineral skim-coat from Renovo line (see Simeto) and let dry. Wet the support before application and wait the superficial water to evaporate.

 

Application

Product is ready to use, just mix briefly before application. Apply with a steel spatula in two coats, with a 12 hours gaps at least between coats. Once the second coat has dried out the surface can be treated with a wet sponge spatula, applying circular gestures, in order to obtain a rustic finish. To obtain a smooth finish, treat the surface with a steel spatula.

Recommendations

Do not add any binding agents, inerts or other materials to the product. Do not apply it in windy days or in rain forecast, do not apply on hot surfaces, under direct sunlight, use adequate protection devices (windbreakers, sunshieldings). Do not apply with temperatures lower than +10°C or higher than +35°C and humidity >75%. Protect the surfaces from rain for at least 48 hours. Apply on cured supports.

Because of natural raw materials, color variation may occur among production batches. To avoid color differences, large surfaces must be worked with product from the same batch. Avoid the application of the material on the same surface on different times and weather conditions, because this could cause color variations. It is recommended to fetch the material in one batch.

To obtain a good looking finish it is recommended, once the surface dried out, to apply a transpirant siloxanic protector (Metauro or Secchia), in order to maintain the structure of the tint and protect the product during the curing phase.

Protect eyes during application and in case of contact, wash with water. Refer to safety sheet for further details.
