.Freeze/Thaw Effect of Har-TnA Courts <br />Frost occurs in the Har -Tru clay court surface profile when water in the <br />surface freezes, Depending on t1w extent of the freezing weather, frost <br />may extend through the entire 1" thickness of Har -Tru, When sunlight and <br />higher temperature reach the frozen surface the fallowing morning, these <br />ice crystals will begin to malt from the top of the surface downward through <br />the profits. <br />It may take several hpurs for all ice crystals to melt in the profile. While <br />these ice crystals are melting, water wilt farm on top of the surface and form <br />puddles until the entire surface below begins to thaw. Once the profile, has <br />thawed completely the water will drain through the profile, <br />Until the entire profile has thawed and the water has drained back drawn <br />into the profile, the surface may be torr wet for maintenance practice s and <br />for 'tenni„ play. We recommend everyone stay off the surface until it is <br />playable and workable since Any traffic on a wet surface may compromise <br />they quality of that surface. if players or court maintenance staff enters•thp <br />playing area before this drying cycle is complete, minor damage to the <br />surface can occur, <br />To repair the indentations (footprints, roller marks, etc.) caused by entering <br />the playing area too quickly, use standard patching techniques or call Har - <br />Tru $ports or your local filar -Tor Clay Court m aterW distributor for <br />guidance. <br />42 <br />
