|Ready-to-use; No mixing or dilution required
|Contains fugitive dye for easy visual confirmation of
|VOC-compliant...meets the U.S. EPA Architectural
Coatings Rule requirements
|For interior and exterior, vertical and horizontal
SURFACE PREPARATION: New concrete must be
cured a minimum of 7 days. Lightweight structural concrete must dry for 14 days.
Concrete surfaces must be clean, smooth, dry and structurally sound. For
additional surface preparation requirements, see instructions for applying MEL-DEK,
MEL-GARD, MEL-ROL, AIR-SHIELD and/or MELNAR Waterproofing Membranes.
APPLICATION: Apply MEL-PRIME W/B in fair weather when the surface and air
temperatures are 40ºF (4ºC) and rising. Apply with a sprayer, roller or brush
at a coverage rate of 250 to 350 ft.²/gal. (6.14 to 8.59m²/L).
Prime only the area to be covered with the waterproofing membrane during the
working day. Areas not covered with a membrane in 24 hours must be reprimed.
DRYING TIME: Allow to dry for one hour or until there is no evidence of
dampness. If the work area is very dusty, apply membrane as soon as possible
after MEL-PRIME W/B is dry.
NOTE: Metal surfaces do not require priming; however, they must be clean, dry
and free of loose paint, rust or other contaminants.
CLEANUP: Application equipment may be cleaned with soap and water before the
MEL-PRIME W/B dries. Once dry, equipment may be cleaned with mineral spirits.

Do not apply MEL-PRIME Water-Base Primer when rain is imminent, on
frozen or frost covered surfaces, when surface and air temperatures are below
40ºF (4ºC) or when the weather conditions are cold and damp. Avoid allowing
MEL-PRIME to puddle – this will lengthen drying time. Use "as is",
do not dilute. Refer to Material Safety Data Sheet for complete health and
KEEP FROM FREEZING.
