ST 30 THERMO

Fiber reinforced one-layer cement render

Pre–mixed one–layer, cement–based fiber reinforced render with selected aggregates and special additives. Required only mixing with water, thus increasing the rate of application. It is easily applied to horizontal and vertical surfaces with a spatula, trowel or plastering machine.

Consumption: 13 kg/m²/cm thickness
Color: White
Package: Paper bags 25 kg
Pallet: 1350 kg

Description

  • Fiber reinforced one-layer cement render ST 30 THERMO:
    • is suitable for:
        • smooth masonry thicknesses up to 15 mm in one layer
        • plastering of brick or concrete walls and ceilings
        • it simplifies and accelerates the application
        • internal and external application
        • smooth or rough surfaces
    • has:
        • excellent adhesion
        • high elasticity
        • excellent workability
        • stable quality
        • vapour permeable
        • medium–grain, traditional textured finish
  • Bulk density: 1.4 ± 0.1 kg/L
  • POT life: ≈ 60 – 90 min /20°C
  • Application temperature: from +5°C up to +35°C

Substrate preparation:

Remove deteriorated and loose concrete parts until the substrate is solid, strong and rough. Surfaces must be clean, free of dust, dirt, oil, grease, rust and other elements that might compromise adhesion. Soak the substrate with water before applying ST 30 THERMO.

Preparation of the mix:

Mix the content of the 25kg paper bag containing ST 30 with 4.0 – 50. liters of clean and fresh water by means of appropriate electric stirrer at low speed (500 rpm) for 3 min, until a uniform mortar free of lumps is obtained. During hot periods and in general, it is recommended to avoid direct sunlight exposure of the materials (in powder or liquid form) before use, otherwise the working time is reduced. For small quantities mixing can be performed also by hand.

Application:

The mixture is applied by means of a flat spatula, trowel or plastering machine, in horizontal and vertical surfaces applying enough pressure and compacting the material well to the surface. The maximum application thickness is 15 mm per layer. When higher thickness is required, apply subsequent coats when the preceding layer starts to harden.
The mortar should be applied under normal conditions within 60-90 minutes of mixing. After this period do not try to mix it with water again. Low temperatures extend the life of the mortar while high temperatures reduce workability. After applying ST 30 THERMO, it should be allowed to mature in a relatively humid environment. Protect fresh mortar from rapid drying by appropriate means.

Recommendations:

  • Avoid applications during direct sunlight exposure and/or strong wind and rain
  • Apply only upon solid and well-prepared rough substrate
  • Do not add water or additives once the mix starts to set
  • Do not apply upon existing expansion or movement joints of the substrate
  • Do not add cement, gypsum, lime or other materials that might affect the properties of the mortar
  • Do not apply upon substrates subjected to rising humidity
  • Do not exceed 15 mm in thickness per layer and 30 mm in case of small areas
  • Do not apply when temperature of the substrate and environment is lower than +5°C and higher than +35°C
  • Do not apply upon anhydrite-based substrates, metal surfaces or resilient substrates
  • Application must be done by professional applicators

Cleaning:

Tools, buckets, tiles etc. can be cleaned with fresh and clean water as long as ST 30 mix is still fresh. After hardening occurs, cleaning can take place by mechanical means.
