Webermin P 1.5
Webermin P 1.5 is a cement-based, polymer-modified decorative exterior coating with a 1.5 mm texture that provides an aesthetic, durable, and long-lasting finishing solution for exterior facades. Thanks to its high water vapor permeability, resistance to environmental conditions, and ease of application, it is a preferred choice for both new construction projects and facade renovation works. The product is specifically designed as a finishing coat for exterior thermal insulation systems.
Advantages of Webermin P 1.5
Breathable Surface: High water vapor permeability helps regulate moisture within the wall structure.
Weather Resistant: The cement and polymer-enhanced formula provides long-lasting protection against environmental factors.
Water and Frost Resistant: Delivers reliable performance under exterior weather conditions.
Decorative Appearance: The 1.5 mm textured finish creates an attractive facade appearance.
Easy Application: Can be applied quickly and efficiently with a homogeneous mix and trowel application.
Areas of Use
- Exterior facade coatings
- Finishing coat applications in exterior thermal insulation systems
- Decorative coatings for new construction and renovation projects
Suitable Substrates
- Cement-based plasters
- Fair-faced concrete surfaces (primed with webertec R, RK, or RM)
- Aerated concrete surfaces with suitable plaster applied
For other substrates, consultation with the manufacturer is recommended.
Surface Preparation
- The substrate must be clean, sound, and smooth.
- The surface should be moistened before application.
- In hot and windy weather conditions, saturating the substrate with water is recommended.
Application Conditions
- Ambient temperature: +5°C to +30°C
- Do not apply under direct sunlight or in excessively hot or humid conditions.
- Do not apply on frozen surfaces or surfaces at risk of freezing.
Application Steps
Mixing
- Add 6–6.5 liters of clean water to each 25 kg bag.
- Mix with a low-speed mixer for approximately 5 minutes.
- Allow the mixture to rest for 5 minutes.
- Remix before application.
Application
- Apply evenly using a steel trowel.
- Spread the material to a uniform thickness across the surface.
- Create the texture using a plastic trowel with circular movements while the material is still wet.
