How To Use

It is recommended to add glass fiber Anti-crack chopped strand into wet concrete during the last stage of mixing, or directly into a ready-mix concrete truck on the job site. For dry-mix applications, fibers can be added into the dry premix.

The recommended dosages are:

Packaging & Storage

HardTape anti-crack HT12mm: Packed in 1000g paper bags (water dispersible), and plastic bags (5 kg)

Anti-crack HT 18mm: Packed in 5 kg plastic bags

Anti-crack HT 24mm: Packed in 5 kg plastic bags

HardTape Anti-crack  glass fiber chopped strand should be stored away from heat and moisture, and must stay in its original packaging.

Optimum conditions are temperature between 15°C and 35°C (59ºF to 95ºF) and humidity between 35% and 65%.

If the product is stored at lower temperatures, it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.
