Surface Preparation
New concrete must be cured a minimum of 7 days. Light-weight 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-GARD, MEL-ROL, MEL-DEK, AIR-SHIELD and/or MELNAR Waterproofing Membranes.

Apply MEL-PRIME in fair weather when the surface and air temperatures are 25F (-4C) and rising. Apply with a roller or brush at a coverage rate of 250 to 350 ft/gal. (6.14 to 7.37m/liter).

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 the primed 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.

NOTE: Metal surfaces must be primed. They must also be clean, dry and free of loose paint, rust or other contaminants.

CLEANUP: MEL-PRIME Solvent-Base VOC Primer may be cleaned with mineral spirits.

1 gallon (3.79 liter) Units
5 gallon (18.93 liter) Pails

Do not apply MEL-PRIME Solvent-Base VOC Primer when rain is imminent, on frozen or frost covered surfaces, when surface and air temperatures are below 25F (4C) or when the weather conditions are cold and damp. Avoid allowing MEL-PRIME VOC to puddle this will lengthen drying time. Use "as is", do not dilute.
