A quart of SealGreen Finishing Sand will cover an average of 45 linear feet (1/2 inch wide joint). It all depends on how much sand you apply. If you apply the sand when the weather is hot the caulk will be softer, and the sand will sink more. If you apply the sand when the weather is cold it will use less. All these variations will have an impact on how much a quart of sand will cover.
