Beyem S-Color

One coat weather resistant colored render suitable for spray machines

BEYEM S-COLOR is a rainwater-proof, rendering and plastering colored dry mortar, formulated with white cement, selected aggregates, special additives and inorganic pigments. 

  • Suitable for spray render and pump machines or manual applications.
  • Good mechanical strengths.
  • Applicable  directly to the building enclosure.
  • High workability.
  • Float/sponge/trowel smoothed finishes.
  • Rainwater-proof and permeable to water vapour.
  • Suitable for internal and external walls.
  • Easy and  fast application.
  • Factory produced for consistency of proportioning.
  • Through-coloured render. Wide range of colours.

Mineral render for facade decoration, suitable for brickwork and  concrete block enclosures. Suitable as a colored coat finishing render or as a base coat for receiving mineral plasters, paints  and ready to use dispersion/silicate/silicon resin based renders.  As an undercoat in others multi-coat render systems.  Interior plastering. Suitable for  walls and ceilings  both in  interior and exterior situations, manually or mechanically. 

BEYEM S-COLOR is suitable for:

  • Bricks.
  • Concrete blocks.
  • Concrete  (treated with BEYEM UNIÓN MORTEROS adhesion promoter primer).
  • Cement based substrates.
  • Fábrica de ladrillo o bloque cerámico.
  • Bloque de hormigón.
  • Hormigón (tratado con puente de unión tipo Beyem Unión Morteros).
  • Soportes convencionales a base de cemento.

Substrates must be clean, compact and  free of substances that reduce adhesion such as dust, oil, grease and with no loose material. Substrates must submit an adequate porosity and surface roughness. Uneven areas must be corrected.  Dampen substrates with water  to cool down if they should be too warm, in case of wind or over absorbent substrates  and wait until the thin layer of water disappears. It is a good practice curing with a fine spray of clean water  24 h after application.

Do not apply on cellular concrete, gypsum based plasters, paint, plastic, wood or materials with  low mechanical properties.

En caso de calor o viento, conviene humedecer el soporte y esperar a la desaparición de la película de agua así como  humedecer el mortero 24 horas después de la aplicación.

No aplicar sobre hormigón celular, yeso, pinturas, superficies de metal, plástico y materiales de poca resistencia mecánica.

Mix manually of mechanically BEYEM S-COLOR with 3,5-4,5 l per bag of clean water until a homogeneous, creamy and lump-free paste  is obtained. Let the mix stand for 5 minutes before application.

To apply with render  spray machine, it´s necessary to set the relation water/mortar  and pump pressure depending on section and length of hose  and climatology conditions. It´s important to maintain the  variables affecting the properties of the applied mortar (distance to the wall, angle of application and water proportion). Spread the mixed product with a trowel (in case of manually or mechanically application) leaving  10 mm of average  thickness. Press to ensure adhesion and expel the air contained in the pores. Smooth with a ruler the applied material to regulate thickness. When BEYEM S-COLOR is green (set but not fully hardened) it should be  finished using a stainless steel trowel, wooden, plastic or sponge float according to the desired effect. 

  • Always mix with the specified amount of water.
  • Do not apply below 5ºC or above 30ºC.
  • Do not apply when there is  risk of frost, rain, strong wind or direct sunlight.
  • Above 10 mm of thickness, apply the product in two layers, leaving a roughness surface in the first to improve the adhesion of the second layer.
  • The minimum finishing thickness of render must be 10 mm, to contribute actively to the  waterproofing of surface.
  • Es necesario armar el mortero con malla en los puntos singulares donde se acumulen tensiones (dinteles, forjados, puertas, unión entre soportes de distinta naturaleza…).
  • Respetar las juntas de dilatación.
  • Para soportes de muy alta absorción, tipo hormigón celular, o de muy baja absorción, es necesario aplicar una imprimación previa.
  • Variaciones de las condiciones climáticas durante la aplicación, así como la aplicación en varias fases  pueden producir  cambios de tono.
