What is the recommended dosage in dry-mix mortar?

For most dry-mix mortar applications, the recommended dosage is 1–3 kg per ton of material. The exact amount may vary depending on the specific formulation and foam-related challenges.

Dosage Guidelines for Dry-Mix Mortar:

1 kg/ton

Light foam control for standard applications

2 kg/ton

Moderate foam suppression for typical conditions

3 kg/ton

Maximum foam control for challenging formulations

                                Professional Recommendation: Start with 1-2 kg/ton and adjust based on your specific formulation requirements and foam challenges.
