Solvent-Based VOC Adhesive
MEL-PRIME is a solvent-based, ready-to-use adhesive for W. R. MEADOWS membrane systems. It is red to reddish-brown in color.
MEL-PRIME simultaneously prepares and dustproofs new and old and vertical and horizontal surfaces in one easy, economical operation. MEL-PRIME is designed for surfaces to receive waterproofing and air/vapour barrier systems from W. R. MEADOWS. Use MEL-PRIME on surfaces to receive applications of MEL-ROL®, PRECON®, MEL-DEK™, and/or AIR-SHIELD™ from W. R. MEADOWS.
- High solids for optimum performance.
- Ready-to-use … no mixing or dilution required.
- For exterior vertical and horizontal applications.
3.78 L (1 U.S. Gallon) Can

When stored indoors in original, unopened containers at temperatures between 4° – 32° C, optimum performance and best use is obtained within two years of date of manufacture.
Surface Preparation … 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 … Apply MEL-PRIME with a roller or brush at a coverage rate of 6.14 – 7.37 m2/L (250 – 300 ft.2/gal.) 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. MEL-PRIME should be used at temperatures of -18° C and above for maximum adhesion.
Drying Time … Allow 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 … MEL-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 – this will lengthen drying time. Do not dilute; use as is.
