Optimix TA313 C1TE Tile Adhesive (Semi-Flexible) / 25KG

Product Overview

Optimix TA313 Semi-Flexible Tile Adhesive is a high-quality polymer-modified cementitious adhesive that is easy to mix and apply. It offers good open time and working time, allowing easy positioning and adjustment of wall and floor tiles. The product delivers excellent all-round bond performance with a degree of flexibility to ensure long-term durability. For enhanced efflorescence resistance, consider Optimix TA313S.

Key Features

• Semi-flexible formula — accommodates minor substrate movement, effectively reducing hollowing and debonding
• 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
• 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 and CIC Green Product Certification (per manufacturer)

Applications

• Interior and exterior wall and floor tiling
• Terrazzo, recycled tiles, homogeneous tiles and general ceramics
• Paper-faced mosaic tile installation
• Modular Integrated Construction (MiC) projects
• Light-traffic floor installations

Limitations

• Cannot be applied directly onto gypsum-based surfaces — proper interface treatment is required
• Suitable for light-traffic floors; high-impact, vehicular, heavy machinery or industrial applications require specialist consultation
• 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

FAQ

What is the difference between TA313 and TA313S?

TA313S is the enhanced version of TA313, offering improved efflorescence resistance. If white deposits tend to appear in tile joints — especially in outdoor or damp environments — TA313S is the recommended choice.

Is TA313 suitable for large-format floor tiles?

TA313 is a C1TE-grade semi-flexible tile adhesive, suitable for standard-size interior and exterior tiles. For larger or heavier tiles, consider the higher-grade TA328 or TA338 high-strength tile adhesives.

What is the difference between tile adhesive and traditional sand-cement mix?

They refer to the same category of products by different names. Polymer-modified tile adhesives like the Optimix TA313 offer stronger bonding than traditional cement-sand mixes and include flexibility for added durability.
