KULBA UNIL Sandsteinfestiger OH 100 (Sandstone hardener)


PRODUCT TYPE
Stone hardener with impregnation properties against water. KULBA UNIL  Sandsteinverfestiger H has an excellent penetration power. The one-component system offers a simple application process. It offers hardening and impregnation in one single step. Pollution is prevented by the non-sticky and clear surface after drying time. The stone is not affected by side-products or side-reactions (salt formations, binder etching, etc.). Since no film is formed, a high gas permeability is guaranteed.

FIELD OF USE
KULBA UNIL Sandsteinverfestiger H is a ready to use, solvent containing product for the hardening and impregnation of absorbent, porous mineral construction materials.
Main field of application is the restoration of natural stone, stucco and frescoes as well as brick and terracotta. Stone which lost binding agents due to weather influences receives new binders through the product application and is also impregnated against water.
KULBA UNIL Sandsteinverfestiger H is absorbed through the capillaries of the substrate and transported to deeper layers. Silica gel (approx. 300-340 g / kg product) forms as a new binder in a catalysed reaction with air moisture and water adherent to the capillary walls. The end of this reaction (i.e. final strength) is after approximately after 2 weeks at 20°C/60% rel. air humidity.
KULBA UNIL Sandsteinverfestiger H is not suitable for the hardening of flaking components, because they cannot be connected to the underground.
