Clay plaster strengthener - Baumit VitonFestiger


Baumit VitonFestiger is:-

  • a water based Potassium Silicate primer for internal and external use
  • ideal for strengthening soft sandy surfaces, especially clay plasters.
  • improves abrasion resistance and reduces surface 'chalking' without reducing permeability.

Where is it used?

  • It is used internally or externally.
  • On the surface of applied plasters or as an admixture to plaster mixes.
  • In areas where impact or abrasion will occur regularly.
How is it used?
  • Surfaces should be clean, dry and free of dust and salts. 
  • Sandy/damaged surfaces should be brushed with a stiff brush to remove loose material.
  • Protect surrounding areas with appropriate plastic sheeting. The product is caustic and will react with metals.
  • One part Baumit VitonFestiger clay strengthener should be mixed two parts clean tap water and applied with a soft brush or by spraying.
  • Once the product has been applied to the surface of the plaster no water or other products should be applied until fully dried.
  • Initial drying time is 2-3 days and full silicification is reached in around 14 days after which other products can be applied if required.

How much will you need?

  • Each can contains 10 litres and will treat up to 160m2 of surface once diluted, depending on absorbency.
