    Clean and dry all surfaces.

    Remove old sealant with stiff brush and isopropyl alcohol.

    Shake well before use. Remove inner foil.

    Pour small amount of Tent Sure into plastic container.

    Apply a thin film onto fabric with foam brush. Apply to coated side of fabric (or inside of item).

    For best results use an even, sweeping motion to avoid puddles or over-application.

    Some high-wear areas like tent floors may need two applications.

    NOTE: Two thin applications are more effective than one thick application.

    LET TENTSURE DRY FULLY for 24 hours at room temperature before use. Keep treated fabric surfaces separated while drying. Test for dryness before use or folding.

    CLEAN-UP AND STORAGE: Wash brush or squeegee with soap and warm water immediately after use; stiff bristles may be loosened with lacquer thinner.

    Store in a cool, dry place. Tent Sure is freeze/thaw stable and washable/dry-cleanable.

    To sharpen a knife, slide the knife across the sharpening stone as though you are trying to cut a thin slice off the stone. Hold the blade at roughly a 20 degree angle and draw it steadily. Be sure to count the number of strokes and do the same number of strokes on the opposite side.
