BIOPRIMER PRO FINE

Plasters adhesion primer with coloring capability

  • Easy application.
  • It is characterized by deep penetration into the substrate and the creation of a slightly rough surface.
  • It limits the risk of microcracking in the final render.
  • It is ideal for external thermal insulation systems.
  • It ensures uniform drying and contributes to the color stability of decorative plasters.
  • Its fine granulometry helps to reduce the consumption of decorative plasters.
Composition & Features

• Aqueous solution of polymeric dispersion, enriched with quartz sand of selected granulometry and special improving additives.

Application

• The substrate must be firm, dry and clean. • Before the application, the contents of the plastic container must be thoroughly stirred. It can be diluted with up to 20% water. In case of dilution, it is recommended that the contents are consumed within 2-3 days. Within these time limits, the separation of the phases, after dilution, does not affect the properties of the product. In this case, good stirring is recommended. • It is applied to the surfaces with a roller, a brush or with the special automatic spraying device. • The coated surface is ready for plastering after drying for 4 to 8 hours depending on the weather conditions and the type of substrate. • The application temperature should be between +5 oC and +35 oC.

Packaging & Storage

• In containers of 17 kg and 4 kg in pallets. • In sealed containers and in a dry environment, protected from frost and prolonged exposure to strong sunlight for 12 months from the date of production.

Consumption

Approximately 250-350 gr/m2, depending on the thickness of the layer, the dilution and the type of substrate.
