What Are the Water Curing Frequency Requirements for GRC Panels? GRC Curing Process Standards

The watering frequency for curing GRC panels is determined by ambient temperature: at 20-25℃, water 3-4 times per day; at 25-30℃, 4-6 times; above 30℃, 6-8 times. Watering should be done in the morning and evening, with the water temperature within 15℃ of the panel surface temperature, keeping the surface moist but free of standing water. The curing period must be no less than 7 days.

Scientific curing increases GRC strength by 20% and reduces shrinkage cracks by 60%. In one project, an automatic sprinkler system precisely controlled the watering frequency, achieving remarkable curing results—components were crack-free and strength met specifications. In contrast, comparative specimens without standardized curing developed surface crazing and lost 15% of their strength.

Temperature-Based Adjustments

For every 5℃ rise in temperature, add 1-2 watering sessions; these adjustments adapt to the environment.

Selecting Watering Times

Morning and evening watering avoids evaporation; these choices improve efficiency.

Water Temperature Control Requirements

The temperature difference between water and panel surface must be ≤15℃; these requirements prevent thermal shock.

Curing Period Regulations

Standard curing lasts 7 days; these regulations ensure strength development.

Curing quality determines final performance. Qinglong GRC scientific curing ensures quality.
