Recommended Use
Characteristics
Silexcolor Tonachino is a one-component, fibroreinforced, modified potassium-silicate based coating, with selected fillers and pigments which are resistant to natural light, applied on internal and external vertical surfaces. Once the silicatisation reaction has been completed, Silexcolor Tonachino forms a single body with the substrate and covers defects, without modifying its permeability.
Silexcolor Tonachino contains synthetic fibres for good crack resistance. Silexcolor Tonachino has excellent resistance to ageing, freezing weather conditions and de-icing salts, and it is very difficult for dirt to remain attached to the surface. Silexcolor Tonachino is also available in a wide range of colours obtained using the ColorMap automatic colouring system.
Silexcolor Tonachino must always be applied on substrates treated beforehand with Silexcolor Primer or Silexcolor Base Coat. If there is a high saline concentration and/or rising damp, only use Silexcolor Primer. Silexcolor 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 requiring treatment or areas patched up with repair mortar must be well-cured, perfectly clean, coherent and dry. Remove all traces of oil and grease from the surface and any areas which are not well adhered. Seal all cracks and repair deteriorated areas. Seal porosity and even out the surface of the substrate with mortar and smoothing compounds from the MAPEI Building products range.
Apply Silexcolor Primer or Silexcolor Base Coat on dry, well-cured substrates only. Wait until completely dry (12-24 hours) and proceed with application of Silexcolor Tonachino. To make application of the versions with particle size 1.2 mm, 1.5 mm and 2 mm easier and to help them cover better, use the same shade of Silexcolor Base Coat.
Preparing the product
Silexcolor Tonachino is ready-to-use. If it is slightly thick, add 3-5% of Silexcolor Primer and mix the product with a low speed drill fitted with a whip to avoid entrapped air. Mix until the paste is completely uniform.
Application of the product
Apply Silexcolor Tonachino with a stainless steel or plastic spreader over the dry Silexcolor Primer or Silexcolor Base Coat. The protection cycle consists of the application of one coat of Silexcolor Tonachino: spread an even coat of product on the surface, then go over the product with a plastic float to create an even finish or with a damp sponge float to create the effect required. Depending on the particle size of the product and the roughness of the substrate, two coats may be required to form a perfectly even aesthetic effect.
