SPECIFICATIONS/STANDARDS

Complies with all current federal, state, and local maximum allowable VOC requirements, including U.S. EPA, SCAQMD, and OTC.

APPLICATION
Surface Preparation … Concrete should be clean, dry, smooth, and free of all voids. Repair spalled areas, fill all voids, and remove sharp protrusions. For additional surface preparation requirements, see instructions for applying MEL-DEK, MEL-ROL, and/or AIR-SHIELD.

Mixing … Product requires thorough mixing prior to application.

Application Method … Apply MEL-PRIME W/B in fair weather when the surface and air temperatures are 40º F (4º C) and rising. Apply with a sprayer*, roller, or brush. Condition only the area to be covered with the product membrane during the working day. Areas not covered with a membrane in 24 hours must be reconditioned. NOTE: Metal surfaces do not require conditioning; however, they must be clean, dry, and free of loose paint, rust, or other contaminants.

*Only specific sprayers will work with the product. Hand-pump sprayers are not recommended for application. Please contact W. R. MEADOWS if spraying for proper recommendations.

Drying Time … Dries in approximately one hour, depending on temperature and application rate. Surface must be tacky to the touch before covering. If the work area is very dusty, apply membrane as soon as possible after MEL-PRIME W/B is dry.

Cleanup … Application equipment can be cleaned with soap and water before MEL-PRIME W/B dries. Once dry, equipment can be cleaned with mineral spirits.

PRECAUTIONS
Do not apply MEL-PRIME W/B when rain is imminent, on frozen or frost-covered surfaces, or when surface and air temperatures are below 40º F (4º C). Avoid allowing MEL-PRIME W/B to puddle – this will lengthen drying time. Do not dilute, use as is. KEEP FROM FREEZING. Refer to Safety Data Sheet for complete health and safety information.
