Optimix SA329 C2FT Stone Floor Adhesive (Fast-Setting) / 25KG

Product Overview

Optimix SA329 is a fast-setting, high-quality polymer-modified cementitious stone adhesive that is easy to mix and apply. It offers good open time and working time while setting rapidly to achieve the required strength in a short time. This allows easy positioning and adjustment of tiles and stone during installation, while enabling earlier grouting and faster reopening to foot traffic. Its high polymer content delivers outstanding bond performance and excellent flexibility, making it the ideal choice for large-format stone subject to loading or impact.

Key Features

• Fast setting — rapid strength gain significantly reduces site closure time, enabling earlier grouting and foot traffic
• High bond strength and flexibility — high polymer content delivers outstanding bond strength and elasticity
• Suitable for all stone types — including large and heavy natural stone
• Grey or white available — to match different stone colours
• Good thixotropy for convenient application
• Suitable for both thin-bed and back-buttering methods
• Consistent quality, easy to use
• Locally produced in Hong Kong — contributes to BEAM Plus green building credits
• Low volatile organic compounds (VOC) — compliant with HKEPD regulations (per manufacturer)

Applications

• Floor stone installations requiring rapid return to foot traffic
• All stone installations, including large and heavy natural stone
• Natural stone, terrazzo, recycled tiles, homogeneous wall and floor tiles, and paper-faced stone
• Modular Integrated Construction (MiC) projects
• General application thickness range

Limitations

• Cannot be applied directly onto gypsum-based surfaces — proper interface treatment is required
• Has moisture-resistant properties but is not a dedicated waterproofing coating
• For porous natural stone (e.g. marble), an additional waterproofing layer is recommended to prevent staining

Packaging

Important Notes

• Clean the substrate before application — remove all dust, oil and contaminants

• For detailed application methods, coverage rates and technical parameters, please refer to the official product data sheet

FAQ

What is the difference between SA329 and TA328?

SA329 is a fast-setting stone adhesive (C2FT) — its key advantage is rapid strength gain, making it ideal for projects requiring quick return to foot traffic. TA328 is a standard-setting flexible tile adhesive (C2TE S1) with a longer working time. Both offer high bond strength and flexibility.

How quickly can SA329 be walked on?

SA329 is a fast-setting formula that achieves the required strength far more quickly than standard adhesives, significantly reducing post-installation closure time. Grouting can commence shortly after installation, followed by reopening to foot traffic. Actual timing depends on site temperature and humidity — refer to the official product data sheet for details.

Is SA329 suitable for large-format stone?

Yes. SA329 contains high polymer content for outstanding bond performance and excellent flexibility, making it the ideal choice for large-format stone subject to loading or impact.
