Product overview

Where is it used?

  • Baumit SilikonTop can be used as a finish coat render on all main wall areas.
  • It can be applied on to old and new mineral renders (lime and cement renders), organic base coat renders in the Baumit range and on to EWI systems.

How is it used?

  • Baumit SilikonTop should be gently whisked in it’s tub prior to use to ensure a homogeneous consistency. Up to 1% water can be added to improve workability.
  • Surfaces should be clean, dry, free from dust and suitably cured.
  • All surfaces must be primed with Baumit Premium Primer prior to application.
  • The Baumit SilikonTop is applied with a stainless steel trowel and troweled back to the grit thickness. The surface is then finished with a PVC float using small circular motions.
  • For the best finish apply and finish each panel continuously, without breaks.
  • It is best to use the same person to finish the whole of each panel to avoid differences in texture mid way.

Frequently asked questions

How long does it take to set?

  • Setting times vary with temperature and humidity but in the summer the product will usually be dry enough to resist a shower in a 4-6 hours and sets hard over the next few weeks.
  • In winter the initial drying to resist showers may be extended to more than one day so the finished surface must be protected from dust and rain.
  • To speed up the setting, even in fog or temperatures down to 1°C, use the Baumit SpeedTop additive.
