Beeck Quartz Filler is a white, textured, fibre-reinforced priming coat formulated to level uneven mineral surfaces, bridge hairline cracks, and prepare backgrounds for long-lasting mineral paint finishes. Designed as part of the Beeck Mineral Paint System, it provides a durable, slurry-like coating that enhances adhesion and strengthens the underlying substrate.
Ideal for both interior and exterior applications, Beeck Quartz Filler acts as a preparatory layer to help achieve a smooth, uniform surface before applying mineral paints such as Beeck Beeckosil or Beeck Renosil Coarse/Fine.
Key Features
-
Excellent durability and longevity
-
Bridges hairline cracks and fills minor surface imperfections
-
Levels mineral substrates for improved paint performance
-
Contains silicification-active fillers with 0.4 mm grain size
-
Suitable for internal and external use on mineral backgrounds
-
Free from solvents, preservatives, and biocides
Recommended Uses
-
As a textured primer for absorbent mineral substrates including lime render, cement render, concrete, and mineral silicate masonry
-
For external use, it must be used as an intermediate coat and overcoated with Beeckosil ASF or Beeck Renosil Coarse or Fine
-
Particularly well-suited as a fibre-reinforced primer where enhanced surface bonding and minor crack bridging is needed
Application Guidelines
-
Ensure the background surface is stable, water-wettable, clean, and free from dust, debris, efflorescence, or any separable materials
-
Prior to application, thin Beeck Quartz Filler with 10–20% Beeck Fixative to achieve a brushable consistency
-
Protect freshly applied surfaces from rain, frost, and moisture using appropriate sheeting
-
Always perform a test area to verify compatibility, finish, and consumption
Coverage
-
Approximate application rate: 0.25 – 0.40 kg/m² depending on surface texture and absorbency
-
Perform an on-site test to determine actual coverage for your project
Important Notes
-
For exterior use, Beeck Quartz Filler must be overcoated with a suitable Beeck mineral paint
-
Refer to all technical data sheets, safety information, and guidance documents before use
-
Background preparation, dilution rates, and application method will vary depending on the substrate
Beeck Quartz Filler ensures the highest standard of substrate preparation for mineral paint systems, enhancing durability, appearance, and performance—especially for breathable, conservation-friendly finishes.
