Application and Preparation
To ensure maximum adhesion and long-lasting durability, the surface must be dry, dust-free, and structurally sound. It is recommended to prime the surface with Baumit UniPrimer before applying the plaster for uniform absorption.
Baumit DuoTop is suitable for:
- Mineral substrates such as lime, lime-cement, and cement plasters.
- Concrete and other mineral surfaces.
- Old but well-adhered mineral coatings, dispersion, and silicate paints and plasters.
Application Method
- Mixing – Stir the contents of the bucket well at a slow speed.
- Application – Apply the plaster evenly using a stainless steel trowel, ensuring the layer thickness matches the grain size.
- Texturing – Immediately after application, structure the surface using a plastic float:
- Scraped texture – Formed with circular movements.
- Dragged texture – Formed horizontally, vertically, or in a circular motion.
- Continuous execution – Work in one uninterrupted process across the entire facade surface to avoid visible differences.
