ABSTRACT:
A screed ski system includes a plurality of circlip saddles supported by corresponding stakes and a plurality of sections of screed ski tubing is snap-fit into the circlip saddles. After screeding of a first layer of aggregate or plastic material, the screed ski tubing and circlip saddles are removed as a unit. The spacers are optionally placed on the stakes, and the screed ski tubing and circlip saddles are placed as a unit on the spacers to facilitate screeding of a second layer of aggregate or plastic material over the first. Some of the screed ski tubing can be flexible to provide an arcuate screed ski.
