DOWNLOAD Technical Data Sheet

RHOPLEX™ MC-1834P is a low-odor acrylic polymer emulsion designed for modifying Portland cement compositions. It also can be used as a latex bonding agent to enhance adhesion of new concrete to existing concrete. In addition to excellent adhesion, ultraviolet light resistance, water resistance, and increased mortar strength properties, this modifier offers improved sprayability in a low-odor formulation.

RHOPLEX™ MC-1834P is especially useful for applications with thin sections, excessive vibration and heavy traffic. Applied correctly, this modifier works well on concrete, masonry, brick, wood, glass, metals, and rigid polystyrene and polyurethane foams.

Typical applications

  • regular and lightweight spray-applied coatings
  • cement bond coats
  • traditional trowel-applied stuccos
  • basement waterproof coatings
  • general-purpose patching and repair mortars
  • floor resurfacing and underlayments
  • terrazzo
  • heavy-use industrial/commercial cement flooring
  • binder for certain non-cementitious products (ex: one-package tile grouts)

Performance advantages

  • increased flexural, tensile and impact strengths
  • excellent abrasion resistance and adhesion
  • excellent hardness, toughness and durability
  • low odor and ammonia-free
  • longer mortar pot life
  • improved flow characteristics for spray coat applications
  • uniform color – resistant to discoloration from UV light exposure
  • water resistance
  • chemical resistance
  • air-curing at ambient temperature and relative humidity
  • sediment-free, stable emulsion


These properties are typical, but they do not constitute specifications.
