How much Har-Tru do I need to resurface my court?
Sprinkler irrigated Har-Tru courts will lose material over time due to the effects of watering, wind, rain, and play. Sprinkler irrigated Har-Tru courts in most regions of the country will lose 2-3 tons per year (50-75 80 lb. bags). Sprinkler irrigated courts in Florida lose 4-5 tons per year (100-125 80 lb. bags) due to more rain and year round play. Har-Tru courts must be top dressed on an annual basis to maintain their safety and playability. You can either top dress using a small amount of material (8 bags per court) multiple times per year or top dress using a large amount of material (50-75 bags per court) once per year. However, if you have neglected to add the proper amount of material on an annual basis, a more extensive laser-tapered resurfacing may be needed. In this procedure, laser guided grading equipment is used to remove built-up material at the low end of the court and add new material at the high end of the court to restore the proper court slope. Generally 10-20 tons
