Optimix TA328 C2TE S1 Tile Adhesive

Product Overview

Optimix TA328 is a high-quality polymer-modified cementitious tile adhesive that is easy to mix and apply, with good open time and working time. Its high polymer content provides enhanced flexibility and bond performance, making it the ideal choice for large-format tiles subject to loading or impact. It also offers waterproofing and moisture-resistant properties. For enhanced efflorescence resistance, consider Optimix TA328S.

Key Features

• High bond strength and flexibility — high polymer content delivers outstanding bond and shear bond strength
• Suitable for all tile sizes — including large and heavy tiles, ideal for load-bearing or impact-prone applications
• Grey or white available — white adhesive provides a more uniform colour, ideal for pairing with light-coloured stone
• Suitable for both thin-bed and back-buttering application methods
• Good thixotropy with extended working time for convenient tile positioning
• Waterproofing and moisture-resistant properties
• Lower slurry density for easier, less strenuous application
• Locally produced in Hong Kong — consistent quality, contributes to BEAM Plus green building credits
• Low volatile organic compounds (VOC) — compliant with HKEPD regulations (per manufacturer)
• Certified under China Green Building Materials (3-star) and CIC Green Product Certification at Platinum level (per manufacturer)
• Compliant with Waterworks Regulations Schedule 2 for potable water contact (per manufacturer)

Applications

• Interior and exterior wall and floor tiling (all sizes)
• Large and heavy tile installations
• Emergency vehicular access floor tiling
• Natural stone, terrazzo, engineered tiles, homogeneous tiles and paper-faced mosaics
• Modular Integrated Construction (MiC) projects

Limitations

• Cannot be applied directly onto gypsum-based surfaces — proper interface treatment is required
• If significant substrate or tile movement is anticipated, or for industrial applications, specialist consultation is required
• Has waterproofing and moisture-resistant properties, but where waterproofing is the primary concern (e.g. water storage, damp-proofing), use in conjunction with dedicated waterproofing products

Packaging

Important Notes

• Clean the substrate before application — remove all dust, oil and contaminants
• Product is alkaline — wear protective gloves and eye protection during use
• Store in a cool, dry indoor location away from direct sunlight before use
• After tiling, grouting with Optimix TG410E High-Performance Anti-Mould Grout or TG480 Two-Component Epoxy Grout is recommended
• For detailed application methods, coverage rates and technical parameters, please refer to the official product data sheet

FAQ

What is the difference between TA328 and TA313?

TA328 is a higher-grade flexible tile adhesive (C2TE S1) with greater bond strength and flexibility than TA313 (C1TE). TA328 is suitable for all tile sizes including large and heavy formats, while TA313 is mainly for standard-size tiles.

What is the difference between TA328 and TA328S?

TA328S is the enhanced version of TA328, offering improved efflorescence resistance. If white deposits tend to appear in tile joints — especially in outdoor or damp environments — TA328S is the recommended choice.

Is TA328 suitable for large-format floor tiles?

Yes. TA328 is specifically designed for large and heavy tiles, offering high bond strength and flexibility. It is the ideal choice for large-format tiles subject to loading or impact.
