In the world of architecture and design, innovation often arrives not with a bang but with a quiet sigh of relief. Sika, a global leader in construction chemical products, has done just that with their SikaTile® Silica Free range, released in September 2022.
Tiles have been a mainstay in architecture for hundreds - if not thousands - of years. They’re still used abundantly in construction - from our homes, commercial projects, and even to industrial architecture. For that reason, it’s essential we’re able to get tiling right, both in the quality of the final product, and in ensuring the safety of tilers and construction professionals throughout the installation process. For decades, however, traditional tile adhesives have often contained silica, a known respiratory hazard when inhaled. And while knowledge of the dangers of silica are not new, a recent increase in cases of silicosis (respiratory disease caused by silica inhalation) has driven a renewed regulatory focus on the matter, culminating in the ban on the use of engineered stone on July 1, 2024.
Sika recognised the need for a change, and their response was as elegant as it is practical. SikaTile®-410 Secure Set, SikaTile®-405 Lite, and SikaTile®-510 Mega Lite aren't just new products; they're a paradigm shift. The products are working examples of Sika’s compounding innovation - technology that has been developed by the company’s dedicated technical department to create formulations that comply with AS ISO 13007 – Class C2TES1 without the use of any silica sand.
The holistic removal of silica sand from the process is an important point. While many other manufacturers have opted to reduce their levels of silica sand to bring the final amounts of respirable crystalline silica below required standards, Sika has opted for a different approach. By removing silica sand entirely, the company has eliminated a significant risk factor for workers while maintaining the high-performance standards expected of their products.
Sika's dedication to sustainability doesn't stop at safety. The SikaTile® Silica Free range also boasts lower dust emissions during manufacturing, handling, and application. This translates to cleaner worksites, reduced environmental impact, and potentially even faster project timelines due to less cleanup. The results are compelling, and tests show that Sika's silica-free adhesives maintain performance while generating significantly less dust than traditional counterparts. Sika is bringing to life their vision of tiling projects with less airborne dust, fewer respiratory concerns, and a cleaner working environment.
For architects, designers, and specifiers, SikaTile® Silica Free presents a unique opportunity. By specifying these products, they are not just choosing a high-quality adhesive; they’re able to make a conscious decision to prioritise the health and safety of the people who bring their designs to life. Furthermore, Sika's silica-free technology aligns with the growing demand for sustainable building practices. It's a solution that benefits not only the workers on-site but also the environment and the long-term health of the building itself.
The SikaTile® Silica Free range isn't just an innovation; it's a testament to Sika's commitment to both performance and responsibility. It's a huge step into a future where we think differently - not only about tiling, but about sustainable construction as a whole. And in a world where every breath matters, that's a change we can all appreciate.
