Application Data Step 5: Grouting Instructions and Options Times based on 70°F / 21°C. All dry times are calculated at 70°F (21°C). Drying time is a function of jobsite temperature and humidity conditions. Low substrate temperatures and/or high ambient humidity will extend the drying time. Adequate ventilation and heat will aid drying. Water ratio: Pot life Open time: Adjustment time: 5 - 5 1/2 quarts (4.7 - 5.2 L) of clean water per unit; or 2.
