Fully sealed, out of the light and protected from freezing, a bucket will last 12 months.
Because the product is designed to react with water, if you have an open bucket it will react with moisture in the air and will get hard within days.
If you are storing it somewhere hot, the liquid may settle at the bottom of the bucket. To reactivate, we recommend you put the product upside down in your truck so the liquid filters back through the solids while you drive to your job site.
If your Aquaphalt has frozen, it's important you let it thaw completely before using it.
