Description
HOW TO USE
PREPARATION OF THE SUPPORT: the surfaces must be clean, free from dust, oil, grease, dirt in general, crumbly parts or paint and in any case from anything that could harm adhesion, furthermore they must be suitably prepared with the MICROCRETE TOP base layer (see specific technical data sheet).
PRODUCT PREPARATION: MICROCRETE TOP fine is supplied in pre-measured packages. Slowly pour comp. B into comp. A while stirring and continue until homogenized, adjust the density with small additions of water and apply with a smooth spatula. The mixing ratio between the two components by weight is 17 : 5. In the case of applying two coats, sand with fine sandpaper between one coat and the other. If required, add the necessary coloring (color toner) to comp. B (liquid part) and shake and mix very well.
FINISH: the surface can therefore be finished with various types of finishes according to the aesthetic/technical functional needs. As a matt or glossy finish, we recommend proceeding with the transparent POLYLUX TR/F product (solvent-based) or POLYLUX AQ (water-based) or POLYLUX FINISH matt acrylic-polyurethane system, or with EXTRA MATT protective wax.

CLEANING OF TOOLS
Equipment used for the preparation and application of the product must be cleaned immediately after use with water.
INDICATIVE YIELD
The surface created can be protected and finished with various types of impregnating agents, applying them later between 24 and 48 hours after creation and with a coating that has reached a humidity lower than 5 % measured with instruments suitable for this purpose. As a matt or glossy finish, we recommend proceeding with the product POLYLUX TR/F transparent (solvent-based) or POLYLUX AQ (water-based) or POLYLUX FINISH matt acrylic-polyurethane system, or with EXTRA MATT protective wax.
