ABSTRACT:
The problems associated with patching, sealing and forming ice due to water run off and large imperfections on skating rinks is solved by the use of an additive for treating water which comprises a polymer selected from the group consisting of water gelling starches and polymers of acrylic acid and sodium salt commonly referred to as super absorbent polymers and means for dispersing the polymer in water. The polymer absorbs water, which may be tap water at a temperature in the range of 45.degree.-55.degree. F., producing a generally homogenous mixture with slush-like consistence, when mixed with the water. The mixture may then by applied where patching, sealing or the formation of ice is required. The frozen mixture formed has desirable characteristics for skating. The invention also encompasses novel methods for patching, sealing and forming ice.
