SP Plus - Preservation of Mineral Façades

BEECK SP Plus is a solvent-borne deep-action impregnation and permanently prevents penetration of moisture into porous mineral building materials as a result of spraying, sprinkling and rainwater. By adding a hydrophobic lining to the building materials' pores to induce deep-action water repellency. Protects against capillary water absorption and therefore against water-induced building material corrosion, contaminant input and soiling. Dry building fabric has improved thermal insulation properties and is barely susceptible to algae growth. Air-borne dirt is effectively rinsed off sprayed façades with self-cleaning action. Unlike renders and coatings with "hydrophobic finish", BEECK SP Plus produces a deep impregnating, alkali-resistant long-term preservation of render and coating "homogeneously and seamlessly". With BEECK SP Plus, washing out or leaching of water-repellent additives such as calcium stearate or silicone resin emulsion.

Deterioration of surface hydrophobicity is to be expected due to the natural, surface degradation of substances as part of general weathering of the façade, as well as contaminant infiltration (soot particles, dust, pollen). Cleaning and repeat impregnation around 12–15 years also protects fully exposed outdoor façades durably and economically. Water-vapour diffusion, that is to say the exchange of gaseous water vapour between the building material and atmosphere, remains effective without limitation even after hydrophobing with BEECK SP Plus.

Suitable for subsequent long-term preservation of BEECK ASF® Active Silicate Formulations such as BEECK Pure Crystalline Finish. In this combination, provides optimum contemporary building protection, verifiable through long term references. Cannot be used on external thermal insulation composite systems (ETICS) and synthetic resin render. Apply by flow coating until saturated.

Features and benefits:

• Use only on façades.
• Colourless transparent, not visually perceptible in dry weather.
• Provides long-term protection of porous building materials against rainwater, penetration of moisture and contaminant input.
• Prevents the activation and capillary transport of structurally damaging salts and discolouring ingredients.
• Highly penetrative deep-action preparation.
• Unsurpassed durability as long-term preservation.
• For alkaline and also for chemically neutral substrates.
• Non vapour retarding, valuable in building physics terms.
• Does not block pores, non-thermoplastic or film-forming.
• Binder free, without consolidating effect.
• Optimally compatible with BEECK ASF® Active Silicate Formulations, e.g. BEECK Pure Crystalline Finish.
