FİXA BETOPRIMER – Professional Plaster Primer for Fair-Faced Concrete Surfaces

FİXA BETOPRIMER is a professional plaster primer formulated with acrylic polymers and quartz aggregates to provide excellent adhesion on fair-faced concrete surfaces. Applied before cement-based or gypsum-based plaster systems, it creates a strong bonding bridge between the substrate and the plaster, ensuring improved workability and long-lasting performance.

Product Description

FİXA BETOPRIMER is a quartz-filled surface primer specifically developed for dense, low-absorbency fair-faced concrete substrates.

The quartz particles create a micro-textured surface that improves the mechanical bonding of plaster mortars. Its acrylic polymer-based formulation maintains water vapor permeability, allowing building elements to breathe while enhancing surface durability and adhesion performance.

Areas of Application

• Primer for cement-based or gypsum-based plaster applications on fair-faced concrete
• Gypsum plaster, gypsum cornices, aerated concrete, chipboard, and block surfaces
• Bonding layer for ceiling plaster applications
• Renovation projects and new plaster applications
• Suitable for horizontal, vertical, and ceiling surfaces in both interior and exterior areas

Advantages

Superior Adhesion

Provides strong bonding between plaster and low-absorbency substrates such as fair-faced concrete.

Ready-to-Use Formula

Single-component product requiring no additional mixing procedures.

Easier Plaster Application

Balances surface absorption and improves plaster workability.

Quartz Reinforcement

Creates mechanical anchoring that reduces the risk of plaster detachment.

Breathable Structure

Maintains vapor permeability and helps prevent moisture accumulation within the substrate.

Enhanced Surface Durability

Supports surface integrity and helps minimize cracking risks after application.

Application Instructions

Surface Preparation

The substrate must be clean and free from dust, dirt, oil, loose particles, and form-release agents.

Mixing

FİXA BETOPRIMER is supplied ready to use. Before application, stir with a low-speed mixer for approximately 1–2 minutes to achieve a homogeneous consistency.

Application

• Apply using a brush, roller, or spray equipment.
• Ensure complete and uniform coverage of the surface.
• Allow the primer to dry completely before plaster application (approximately 4–6 hours).

Plaster Application

Once the primer has dried, cement-based or gypsum-based plasters can be applied directly onto the treated surface.

Application Recommendations

• Do not apply at temperatures below +5°C.
• Protect the product from freezing conditions.
• Avoid application under direct sunlight or strong wind.
• Clean tools and equipment with water immediately after use.
• Ensure the primer is completely dry before proceeding with plaster application.

Frequently Asked Questions (FAQ)

1. On which surfaces can FİXA BETOPRIMER be used?

It can be applied to fair-faced concrete, aerated concrete, gypsum board, chipboard, pumice blocks, and masonry block substrates.

2. What is the advantage of the quartz-filled formulation?

Quartz particles create a micro-rough surface that significantly improves plaster adhesion.

3. Can it be used as a paint primer?

No. FİXA BETOPRIMER is specifically designed as a bonding primer before plaster applications.

4. How long should I wait before applying plaster?

A drying period of approximately 4–6 hours is recommended under normal conditions.

5. Is it suitable for outdoor use?

Yes. FİXA BETOPRIMER is suitable for both interior and exterior applications.
