250 to 300 sq. ft./gal. (6.14 to 7.37 sq. m/L)

Shelf life is three years when stored indoors and in original, unopened containers at temperatures between 40 u0096 90u00b0 F (4 u0096 32u00b0 C).

Surface Preparationu0085 All surfaces to receive adhesive must be clean, dry, smooth, and free of all voids. Fill all voids, and remove sharp protrusions. When used on concrete, concrete should be cured at least 72 hours; For additional substrate surface preparation requirements, see instructions for applying MEL-ROL, PRECON, MEL-DEK, and/or AIR-SHIELD.
NOTE: Metal surfaces must also be clean, dry and free of loose paint, rust or other contaminants.
Application Method u0085 Apply MEL-PRIME with a roller or brush at a coverage rate of 250 to 300 sq. ft./gal (6.14 to 7.37 sq. m/L). Apply only to the area to be covered with the membrane during the working day. Areas not covered with a membrane in 24 hours must be re-applied.

Drying Timeu0085Allow to dry for one hour or until the surface feels tacky but does not pick up when touched. If the work area is very dusty, apply membrane as soon as possible after MEL-PRIME is dry.

Cleanup u0085MEL-PRIME may be cleaned with mineral spirits.

Do not apply MEL-PRIME when rain is imminent, or on damp or frost-covered surfaces. Avoid allowing MEL-PRIME to puddle u0096 this will lengthen drying time. Do not dilute; use as is.
