MEL-PRIME™ W/B

WATER-BASE PRIMER

Technical Description
SEALTIGHT MEL-PRIME W/B is a ready-to-use priming compound specifically formulated with polymers in a true water-base emulsion. MEL-PRIME appears reddish-white in the container and dries to a transparent finish with a reddish sheen. Furnished in 1 gallon (3.79 liter) and 5 gallon (18.93 liter) pails. MEL-PRIME W/B meets maximum VOC content limit of 350 g/L for Primers and Undercoaters as required by the U.S. EPA Architectural Coatings Rule.

Uses
Apply SEALTIGHT MEL-PRIME Water-Base Primer to simultaneously prepare and dustproof new and old, vertical and horizontal concrete in one easy, economical operation. Use MEL-PRIME to prime all concrete surfaces to receive applications of SEALTIGHT MEL-DEK, MEL-GARD, MEL-ROL, AIR-SHIELD and/or MELNAR Waterproofing Membranes.

Advantages and Benefits

Application
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.

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

Limitations
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 safety information.

KEEP FROM FREEZING.
