Typically 25–75 mm. Minimum 25 mm for proper flow. Maximum depends on grout type.

Epoxy grout for high loads and chemical resistance. Cementitious for general use and lower cost.

10-15% for simple rectangular shapes. 20%+ for complex shapes with cutouts.

Divide total volume by bag yield (typically 14-25 liters per bag depending on product).

Most grouts require 5-35°C. Epoxy is sensitive to cold; cementitious to frost.
