The BC S900 from BCI Neutral Silicon is a specialized silicon-based material designed for elevation applications, particularly in construction, flooring, and leveling. Here’s what you need to know:
Key Features of BC S900:
1. High-Performance Leveling Compound
- Used for floor elevation, smoothing uneven surfaces before final flooring installation (tiles, epoxy, laminate, etc.).
- Suitable for both interior and exterior applications.
2. Neutral Silicon Base
- Provides *excellent adhesion* to various substrates (concrete, screed, anhydrite, etc.).
- Resistant to *cracking and shrinkage* due to its flexible, durable formulation.
3. Self-Leveling Properties
- Spreads easily and *self-smooths*, reducing labor time.
- Can be applied in thin or thick layers (check manufacturer specs for exact thickness range).
4. Fast Drying & High Strength
- Typically achieves walk-on strength within *a few hours*.
- High compressive strength, making it suitable for heavy-duty areas.
5. Moisture & Chemical Resistance
- Resistant to water ingress, making it ideal for wet areas (bathrooms, balconies).
- Can withstand mild chemical exposure (depends on exact formulation).
Typical Applications:
- Floor preparation before installing tiles, vinyl, or epoxy coatings.
- Repairing uneven concrete surfaces (indoors/outdoors).
- Elevating floors to match different heights between rooms.
- Underfloor heating systems (compatible with many thermal solutions).
Installation Notes:
- Surface must be clean, dry, and free of dust/oil* (priming may be required).
- Mixing – Usually requires precise water-to-powder ratio (follow manufacturer guidelines).
- Application – Poured and spread with a smoothing tool (squeegee/notched trowel).
Manufacturer (BCI Neutral Silicon)
- BCI is known for high-quality construction chemical.
- The "Neutral Silicon" line suggests a low-alkali or pH-neutral formulation, reducing risks of substrate damage.
