Application instructions
Construction sequence from the product source
Surface Preparation
Concrete/render must be sound, dry and clean; new cementitious surfaces require curing, moisture <10% and pH <10.
Application Environment
Normally ≥10°C; substrate ≥3°C above dew point; relative humidity ≤85%; stop below 5°C.
Mixing
Stir the single-component paste until uniform.
Application Tools
Trowel, scraper or airless spray.
Thickness per Coat
Build 2-3 mm in multiple coats; do not apply too thickly in one pass.
Curing
At least 72 h before decorative finish coating.
