Merlex Stucco Keeping it Premium since 1963


Exterior Stucco

  Polymer-modified leveling and base coat for stucco finishes
  Hand applied with embedded fiberglass mesh
  LevelXMerlex LEVELX is specifically designed to level walls and provide a crack- resistant base coat. LEVELX contains a high percentage of polymer for flexibility and bond strength, and additives for workability and working time. The product has suction to ensure good bond between the finish plaster and base coat. LEVELX can also be used on rescrubs directly over structurally sound existing plaster, eliminating the need for sandblasting. When mesh is embedded in LEVELX, cracking is reduced significantly, which allows for higher-quality smooth- troweled finishes, or for any finish when crack tolerances are low.
  • Provides crack-resistance and impact-resistance when used with mesh
  • Evens out suction on different substrates for uniform finishes
  • Ideal for new construction and rescrubs Eliminates need for sandblasting old stucco
  • Ready to use, with all ingredients in the bag
  • An economical alternative to EIFS base coats
  • Available in #20 and #30 grit
  • Provides a durable, hard,water-resistant level and base coat
Textures & Substrates
  LEVELX is suitable for application over standard Portland cement brown coat, concrete masonry units, existing stucco, and poured-in-place concrete.
Components & Storage
  Merlex LEVELX is packaged in 50 lb. bags, 56 bags per pallet. Product must be kept dry at all times.
  Coverage depends on texture of substrate and thickness of mesh used. One 50 lb. sack will cover approximately 50 to 70 square feet at 1/8" thickness over 4 ounce mesh.

Merlex LEVELX should be mixed with clean water to a consistency of pancake batter. This can be accomplished one bag at a time in a bucket with a suitable drill and mixing paddle, or in a mechanical mixer. Do not entrain air by overmixing or using excessive mixer speed. After mixing, allow material to sit for approximately 5 minutes, and then re-temper by mixing for a short period of time.

  Merlex LEVELX must be used in conjunction with alkali-resistant mesh (4 ounce/square yard mesh is available from your Merlex distributor) to achieve its full crack-resistance. Apply 1/8" of LEVELX over the substrate and then immediately embed mesh in LEVELX. An additional coat of LEVELX may be needed to fully bury the mesh. Leave LEVELX rough or use a sponge float in order to achieve mechanical bond when the finish plaster is applied. Wet the LEVELX before applying any cement finish coat.

Allow LEVELX to dry at least 24 hours. No bonding agent is needed if finish coat is applied before LEVELX has fully cured (28 days).
  Immediately clean all tools and mixing equipment with water after use.
  Merlex LEVELX should not be expected to eliminate all cracking, and is most effective for controlling one-time minor structural cracks, including door and window cracks. A surface bonder, such as Merlex Superhold, should be used when applying LEVELX over painted surfaces and smooth surfaces with minimal suction. LEVELX should not be used when temperature exceeds 110°F (43°C) or will fall below 40°F (4°C) within 48 hours of application.
