How to Prepare Your Surface Before Applying Béton Ciré Concrete?
Preparing the surface is a critical step in ensuring the successful application of béton ciré concrete. To achieve the desired result, it’s essential to thoroughly clean the surface before application. Ensure that the substrate is clean, dry, and sufficiently solid. Use specific cleaning agents to eliminate dirt and residues, as a poorly prepared surface can lead to issues such as rising moisture, which may affect the mortar's adhesion.
Preparing Béton Ciré for Porous or Sealed Surfaces
Before starting, answer two important questions:
- What is a sealed surface?
- A sealed surface is non-porous and does not allow for air exchange. Examples include plaster, tiles, or old layers of intact paint.
- What is an open surface?
- An open surface is porous and breathable, such as stone, brick, lime, or cellular concrete. Untreated wood is also considered an open surface.
To identify whether your surface is sealed or porous, apply a small amount of water. If the water is absorbed, the surface is porous; if it beads up, it is sealed.
Steps to Prepare the Surface
- Use the appropriate primer based on the substrate type:
- For sealed surfaces, select a primer designed for non-porous materials.
- For open surfaces, use a primer that enhances adhesion to porous substrates.
- Apply the primer evenly with a roller, ensuring no irregularities are visible.
- Allow the primer to dry for up to two hours, depending on the substrate and ambient temperature.
Preparing Béton Ciré for Humid Surfaces
When working on humid surfaces, such as in bathrooms or kitchens, special primers are required. These primers prevent moisture from compromising adhesion.
Steps for Preparing Humid Surfaces:
- Mix the Primer
- Use a slow-speed agitator to ensure a uniform and homogenous mixture. Correct proportions are crucial for effectiveness.
- Application
- Apply the primer evenly with a roller to the cleaned surface.
- Sandblasting
- Immediately after applying the primer, sand the surface until it’s fully covered.
- Let it dry for 24 hours, then remove excess sand.
Once dry, the surface is ready for béton ciré application.
Preparing Béton Ciré for Tiled Surfaces
To apply béton ciré on tiled surfaces, follow these steps:
- Apply Primer
- Use an adhesion primer and spread it evenly across the tiled surface with a roller. Ensure all irregularities are addressed.
- Drying
- Allow the primer to dry until the surface feels dry to the touch.
- Apply Repair Mortar
- Mix the repair mortar thoroughly, respecting the product’s proportions to achieve a homogeneous consistency.
- Use appropriate tools, such as a trowel, for application.
- Smooth the Surface
- Apply the repair mortar evenly, smoothing it with a sponge to eliminate irregularities before it sets.
- Clean Your Tools
- After completing the application, rinse your tools thoroughly with clear water.
By following these steps carefully, you’ll create a solid and uniform base for the béton ciré, ensuring a flawless and durable finish.
