A well-balanced additive mix for cement-based tile adhesives
As an alternative to screed, cementitious tile adhesives (CTA) have evolved to become essential in modern construction, providing benefits for various tile applications.
The trend toward developing higher-quality CTAs is driven by several factors, including demand for large format tiles, increasing durability and performance requirements for high traffic areas or wet surfaces, and stricter building codes and industry standards such as EN 12004, EN 12008, and EN 12002. Additionally, rising labour costs, faster construction demands, and climate and environmental challenges requiring adaptation to seasonal and regional varying job-site conditions and reducing carbon footprints also play a significant role.
To deliver on this trend, high-quality CTA formulations require a well-balanced formulation of cement, fillers, polymers, cellulose ethers, and additives to ensure adhesion, flexibility, workability, water resistance, and durability. We have selected best-performing additive combinations and optimised cement dosage to provide guide formulations for various CTA performances: C2TE, C2TE S1, C2TE F, C2TE S2.
Benefits:
This advanced CTA formulation is developed for a wide range of tile installations, offering:
- Strong adhesion: suitable for ceramic, porcelain, and natural stone.
- Versatile use: ideal for bathroom tile adhesives, kitchen tile adhesives, pool tile adhesives and floor heating systems.
- Lightweight options: improve handling and increase coverage for cost efficiency.
- Fast-setting tile adhesives: enable rapid installations, minimising downtime for commercial and residential projects.
Key materials:
- Dispersible polymer powders (DPPs): enhance adhesion and flexibility, by improving bonding strength and allowing for decoupling of movements
- High-performance cellulose ethers: optimise workability and ensure smooth application and extended open time.
- Seeding technology: allows fast-setting and high durability, by improving crystallisation for faster curing without compromising strength.
- Lightweight fillers: enhance coverage and ease of handling while reducing weight and material consumption.
- Reduced clinker cement: offering lower CO₂ footprint by optimising clinker dosage and integrating alternative binders.
