BEECK Häftgrund Fin

Silica-based primer with high adhesion, without graininess in texture.

Binder for interior and exterior surfaces with weak silicification. Suitable substrates provide strong adhesion for solid emulsion coatings, synthetic renders, resin-based plastering, and external thermal insulation composite systems (ETICS). Can also be used on smooth coating substrates with low porosity or poor wetting properties, such as stucco, fiber-reinforced cement, dense concrete, and tiles. Maintains consistency for a smooth and even coating.

Approximately 0,14 l/m².

The substrate must be mineral-based, water-compatible, clean, dry, solid, stable, and free from efflorescent and separating substances.

Suitable substrates include shrinkage-free, dimensionally stable, porous to non-penetrable, water-absorbing to water-repellent substrates with at least partially mineral character, such as lime plaster/render, lime-cement plaster/render, cement plaster/render, gypsum plaster/render, stucco, gypsum, gypsum boards, concrete, fiber cement, natural stone, brick, calcium silicate masonry, ceramics, old coverings, synthetic plaster or resin render, and external thermal insulation composite systems (ETICS), provided that the substrate is correctly prepared.

Unsuitable substrates are horizontally exposed, less solid, efflorescent, and non-alkali-resistant substrates such as wood-based materials (MDF, OSB), clay, or loam.

Additionally, thermoplastics as well as old, non-solid, glossy, and plastoelastic coatings are unsuitable.

Defective substrates require different treatments. Apply a non-vapor-permeable moisture-inhibiting renovation plaster or render on damp, salt-attacked surfaces and the base areas.


Check the required suitability of the substrate.

Thoroughly cover surfaces that are not to be treated (e.g., windows, window profiles) and protect them from paint splatters.

Provide personal protective equipment.

Before use, stir the mixture with a power mixer.

Add water until you achieve an optimal coating consistency.

Do not use the product in wet conditions, at risk of freezing weather, on hot surfaces, or under intense sunlight.

Minimum application temperature: +8°C.

Protect fresh coatings from rain and direct sunlight.

Use a roller, brush, or apply using a spray method.

Apply to separate areas with a very thin layer, without overlaps, in one working session, and uniformly coat the surface using a cross-coating technique.

Test on a sample area on-site to determine differences in application amounts based on the substrate.

Please note that the provided text describes specific guidelines for using BEECK products on different types of surfaces. For more accurate information and product usage, it is essential to consult the manufacturer's instructions and recommendations. *Applies to certain colors
