Licata Winter Silicone Render 25kg - 4Seasons

Ready to use coating made with a siloxane binder paste affording high water- repellency and excellent permeability to water vapour, certified in accordance with ETICS standards. Offering excellent mould-proof and anti-algae properties, it is an ideal decoration during styling/functional restoration work on façades and specifically in licatatherm external solid insulation systems. Ideal as a decorative finish in all work requiring high permea-bility to water vapour. Siloxan Color LBS 4S can be applied without the need of any additional additives at low temperatures (down to +1 °C) and at high relatives humidities (up to 95%).

Siloxan Color LBS 4S is a coating made with water-dispersed siloxane binder paste, ready for use and which can be pigmented. Siloxan Color LBS 4S is specifically designed for work on new or existing façades, as well as for the decorative phase of reinforced skim coating, and in licatatherm external solid insulation. Owing to its formula, Siloxan Color LBS 4S licataTHERM, external solid insulation. Owing to its formula, Siloxan Color LBS 4S provides complete protection for the façade against rain and atmospheric agents. The special additives contained in the formula guarantees outstanding protection against algal and mould growth. Ideal as a finish where a high degree of permeability to water vapour is required, such as in damp-proofing work or breathable insulation systems. Combined with colouring pastes, Siloxan Color LBS 4S guarantees good durability, gloss and full colours. Available in 5 particle sizes.

MAIN AREAS OF APPLICATION

Siloxan Color LBS 4S is recommended for decorating external surfaces, whether new or existing, on residential industrial or commercial buildings. IT is advisable to use the product on seasoned substrates, in other words generally after a curing time of four weeks. IT is applicable to substrates such as:

• licataTHERM thermal insulation systems
• Damp-proofing renders
• Thermal renders
• Lime or lime/cement based renders
• Reinforced skim coating in façade restoration work
• Concrete
• Prefabricated concrete panels

For application on other types of substrates, please contact our engineering department.

CHARACTERISTICS

• High water-repellency: the carefully selected latest-generation additives give the coating self-cleaning properties.

• Workability: the thixotropy of the coating combines excellent spreadability of the coating with good adhesion to the substrate to minimise any material peeling during processing.

• Excellent permeability to water vapour: the carefully selected siloxane binders maximises the coating’s properties ensuring the walls breathe without creating a “barrier effect”.

• Improved pot life: Siloxan Color LBS 4S, in standard conditions, makes for easier work on large-size façades thanks to an improvement made to the extended working time.

• Algal and mould protection: the special mould-proof additives found in the formula guarantee an excellent degree of protection against algal and mould growth.• Extensive range of colours: from pastel hues to particularly bright shades, Siloxan Color LBS 4S can be pigmented in over 600 different types of colour.

• Low temperature applicability and high relative humidity compatibility

APPLICATION METHOD

Preparing the substrate

If the surface is old, you will need to remove any blistering parts, in the process of peeling or not sufficiently firm, making sure you restore them subsequently to recreate proper flatness. If the surface is new, we recommend you pre- treat the substrate with a coat of Siloxan LG, in order to even out and reduce absorption, while on existing surfaces presenting a “chalking” effect, apply Nano Primer or Acril Primer Plus to make the surface more compact. On uneven surfaces, apply a coat of Siloxan LG. If the substrate presents mould or algal growth, pre-treat the surfaces affected with suitable biocide such as Sanus. The substrate ready for application must be clean, flat, firm and free of any release agents.

Preparing the product

The product is ready for use and it can be applied by hand or using dedicated equipment. IT is in any case advisable to mix the product using a paint mixer whisk in order to soften the paste, and, in the case of coloured products in medium/ strong shades, to even out the paste with the pigments.

Application

For application by hand, apply the product onto the substrate using a normal stainless steel trowel and mix it using the plastic trowel, crushing and stirring the product in a circular motion. Coating laying that is not applied in a single processing cycle, in an uneven or discontinuous manner could easily create chromatic alterations or “voids” in the coating pattern.

The use of different types of trowels, or mixing with different circular trowel movements during application could compromise the homogeneity of the final appearance of the finish.

On internal substrates, a single coat of the product can be applied, whereas on external substrates, a double layer ofrender needs to be applied to ensure suitable thickness for protection against the weather.

Make sure the surfaces being laid are not exposed to direct sun rays, to wind, and that laying is not carried out in the presence of mist or fog or high degrees of humidity in the air. In the event of direct exposure to sun rays, plan for suitable.
