Morcemcril^® Silicona

Technical Caracteristics

Product based on silicon resin, mineral pigments, and organic and inorganic additives.

Advantages and Uses

• Anti-mould.
• Weather resistant.
• Texture: medium grain.
• Non-flammable.
• Permeable to water vapour, allowing the substrate to breathe.
• Highly breathable.
• Easy and quick to apply.
• Suitable for most substrates.
• Ageing, city-environments, and UV rays resistant.
• Excellent adhesion on traditional construction substrates.
• Easy to clean. Self-cleaning.
• TRADITERM® external thermal insulation system prepared for decorative finish application endorsed/approved by ETE:

This product has a protection against fungus, mould and algae which provides a long-lasting preventive and retardant effect although not permanent. The duration of this affectation depends on the exposure to humidity and the concentration of spores in the area, which create especially favourable conditions for the growth of micro-organisms. Therefore, periodic preventive maintenance treatment is recommended.

Suitable Substrates

• Compatible with cement mortar substrates, concrete, one-coat mortar, gypsum, plasterboard, and painted substrates.
• Traditerm external thermal insulation system prepared for the execution of the final decorative finish. Not compatible with fresh lime plasters, resins or varnishes, distemper paints, lime, or silicate paints. Substrates must be clean, free from dust, greases, old paint, oils, fungus, mould, and any other kind of product.
• New cement plasters must be fully cured (at least 4 weeks old). On surfaces affected by fungi and algae, proceed with their complete removal beforehand.
• Level any irregularities with a suitable amount of paste. Let it dry and sand it.
• Existing deteriorated paints must be completely removed by brushing, sanding, or stripping the surface.
• On surfaces with loose particles, apply FIJAMOR primer beforehand. Apply a FONDO MORCEMCRIL coat before applying MORCEMCRIL MOSAICO
• Apply 3 coats of FONDO MORCEMCRIL in areas where it remains visible (working joints with masking tape).

Application Procedure

• Shake until getting a perfect mixture.
• The product is already ready to use, and it should be applied with a stainless-steel trowel or gun.
• If applied manually, you can adjust its consistency and workability by adding water, up to a maximum of 250 ml per 25 kg container. If applied with a spray gun, you can add water up to a maximum of 1 litre per 25 kg container to adjust the consistency and workability.
• This adjustment will depend on the pump to be used. Stir the product just before applying it.
• In the case of manual application, spread the product evenly using a steel trowel across the entire surface, removing any excess material above the aggregate thickness.
• Once the product has been spread over the substrate and has lost its tackiness, proceed to float the material.
• The surface shall be floated using a plastic trowel or a polyurethane float, floating regularly in circular motions or rubbing horizontally, or vertically.
• Work evenly and uninterruptedly. Preferably with the infinite movement technique to obtain an even textured surface.
• The choice of tool affects the roughness and structure of the surface, so the same type should always be used on a construction site.
• To obtain a uniform structure, it is crucial to make sure that the same person structures adjacent surfaces.
• Due to the natural aggregates and granules in the product, slight colour variations between different batches may occur. Adjacent surfaces should use product from the same batch to ensure consistency.
• For mechanical spraying of the product, the nozzle diameter should be chosen based on the product's particle size distribution.
• During spraying, exceptional care must be taken to apply the product evenly, avoiding overlaps, joints, and uneven loading due to application.
• Cleaning of the tools will be conducted with abundant water immediately after being used. Any dried particles should be removed with solvents such as turpentine.

Recommendations

• Do not apply under 5ºC nor above 30ºC, under direct sun light, rain, or healing risk.
• Do not apply on floors or inclined surfaces where the exposed face is facing upwards.
• Protect the upper surfaces of the render from the penetration of rainwater.
• To ensure colour uniformity, it is recommended to request the total amount of product needed in a single supply. In any case, do not mix different manufacturing batches in one working area.
• In machine spraying application, maintain consistent pressure, angle of projection, and distance from the substrate to avoid changes in the final appearance of the product.
• In machine spraying application, it is recommended to apply multiple coats until achieving the desired coverage and thickness.
• Protect the surrounding area of the surface to be applied and clean any splashes with water before the product dries or hardens.
