Recommended Use
Characteristics
Silancolor Tonachino is a fibroreinforced silicone resin-based plaster that has the advantages of both mineral-based coats (high vapour permeability such as Silexcolor Tonachino) and synthetic based coats (uniform colour tone, excellent adhesion on existing paints that are well bonded to the substrate and a wide range of colours).
Thanks to its special formula, Silancolor Tonachino makes the substrate very permeable to water vapour and considerably water repellent. Unlike normal synthetic coatings, Silancolor Tonachino does not create a film that is waterproof to water vapour because it creates a porous film and, at the same time, the use of special silicone resins does not let liquid water penetrate, ensuring the render remains dry.
Silancolor Tonachino contains synthetic fibres for good crack resistance. Silancolor Tonachino adheres perfectly onto all types of traditional renders, dehumidifiers and well bonded existing paints. Due to its water repellent nature, it protects the substrate from chemical aggression, does not dirty easily, has excellent resistance if exposed to U.V rays and ageing, retaining its properties during the years.
Silancolor Tonachino does not only protect the surface, but has a very pleasant rustic appearance. Silancolor Tonachino is available in a wide range of colours obtained using the ColorMap automatic tinting system. Silancolor Tonachino complies with the requirements of EN 15824 (“Specifications for external renders and internal plasters based on organic binders”) for internal and external use.
Application Procedure
Preparing the substrate
New surfaces to be treated or any renovation with repair mortars must be cured, perfectly clean, well bonded and dry. Completely remove any traces of oils or grease from the surfaces and any loose particles. Seal cracks and repair damaged parts. Seal pores and level any uneven parts of the substrate with mortars and finishing compounds from the MAPEI Building line. Apply Silancolor Primer or Silancolor Base Coat on the dry and cured substrate. After 12-24 hours apply Silancolor Tonachino. To ease the laying of the 1.2 mm, 1.5 mm and 2 mm coatings and to improve the hiding power, the use of coloured Silancolor Base Coat is recommended.
Preparing the product
Silancolor Tonachino is ready-to-use, but must first be stirred thoroughly with a low speed mixing drill. If the product is too viscous, add 1-2% of water.
Application of the product
Apply Silancolor Tonachino with a stainless or plastic trowel on the dry Silancolor Primer or Silancolor Base Coat. The product can also be applied by spray with suitable equipment. The protection cycle requires the application of one coat of Silancolor Tonachino. Spread the product in a uniform layer and level with a plastic trowel to create an even finish or use a damp sponge float to obtain the desired final effect. According to the Tonachino grain size and the roughness of the substrate, the application can be carried out in two layers, to reach a perfectly homogeneous finish
