    Warnings and precautions


    Fibrostuck is specifically formulated for filling, for the regularisation and the levelling of different types of surfaces: concrete, mineral and cement plasters, wood, etc.; it is ready-to-use and must be remixed, slowly, only upon its application
    The three-dimensional reinforcement of nylon fibres provides different levels of finishing and weaving; it can be recoated directly, without resorting to fixatives or insulation materials; it allows the construction of perfect bases for the subsequent application of finishing products.

    Fields of application
    Reclamation of the degenerative condition (cracks and discontinuities) of external walls, prior to the finishing operations, painting, etc.
    Allowed supports
    Cement-based or lime-based mortars
    Preparation of supports
    The surfaces should be clean and free of any dirt, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

    The cracks to be grouted should be preliminarily opened, cleaned, brushed and dedusted; where necessary they should also be treated with the fixative Protech Fix AC.

    Mode of use
    Work by spreading the product with a spatula or steel trowel, grouting or skimming with one or many coats, until achieving the correct filling and/or levelling.
    Avoid applying in conditions of rain and high humidity, which could compromise proper drying with consequent possibility of runoff that may continue for several days.
