FIELD: adaptation of ice surface for speed skating competitions and training.
SUBSTANCE: ice surface creation method involves preparing ice massif for following ice layer application; performing prepared ice machine massif shipping through 0.35 mm depth in single operation; spraying purified water at temperature of 40°-75°C onto prepared surface to freeze the first ice layer; performing machine spraying of water-based composition at temperature of 40°-75°C and freezing of the second and at least one finishing layer during previous ice layer shipping, wherein the water-based composition includes 0.003-0.009% by weight of glycerin and 0.0003-0.001 % by weight of surfactant; holding said layers for time selected from time interval between 20 min and 2 hours at temperature of heat carrier in ice massif base plate pipes equal to -9°C÷ -14°C.
EFFECT: increased ice surface slipperiness.
