Knauf Kati S - Silicate Render - Stone Texture 2.0mm Grain - 25kg tub

Knauf Kati S - Silicate Render 2.0mm grain is a ready‑mixed silicate stone texture render designed for exterior façades requiring a highly vapour‑permeable, mineral‑like decorative finish. Based on potassium silicate binder, it provides excellent breathability, strong adhesion to mineral substrates and long‑term colour stability, making it ideal for both new‑build and refurbishment projects

Applied as a thin‑coat stone texture finish, Kati S produces a fine, uniform mineral texture with a matt appearance. Its mineral‑active formulation ensures reliable weather resistance, natural alkalinity and compatibility with silicate primers and base coats. The render can be tinted within the Knauf colour system for stable, UV‑resistant façade shades.

Consumption: 2.9 kg/m2

Note: The exact consumption can only be determined with a test application on the individual object.
