Repair Mortar Overlay (RMO)

What is CRETO RMO?

CRETO Repair Mortar Overlay is a concentrate designed to be mixed with several different types of masonry products. RMO can be used to fix cracks (large or small), and overlay any type of masonry including concrete, asphalt, and many others. RMO can also be used as a substitute for grout, caulk, stucco, and many other adhesive products.

A RMO can also be colored to match any job. It is highly recommended that RMO be used with CRETO DPS and CRETO TopSeal®.

Please note that CRETO RMO needs to be mixed according to the application instructions for each type of application.

CRETO RMO is a proprietary admixture designed to be used as a modifier for Portland cement. It gives Portland cement unusual and unique properties not obtainable from other admixtures or modifiers.

CRETO RMO contains proprietary copolymer components which induce cross linking in the presence of Portland cement, producing a chemical as well as mechanical bond both adhesively and cohesively.

CRETO RMO is:

  • environmentally safe
  • non-reemulsifiable and will waterproof and seal from the positive or negative side of substrates
  • an excellent priming system, or bond coat, for other coatings and systems.

CRETO RMO, when added to Portland cement, sand and water, provides extraordinary adhesion and flexibility without fatigue, in thickness™ applied from paper thin to as thick as desired. The result is a durable patch and overlay system that will not delaminate, even at a feather edge.

CRETO RMO gives cement base repairs the ability to be used as a permanent repair and/or resurfacer on virtually any sound surface. This includes concrete, masonry, asphalt, wood, metal, and surfaces not normally considered sufficiently bondable.

CRETO RMO enables the creation of various mix designs which could be applied in thickness™ ranging from a foot or more down to the thickness of a coat of paint, with no delamination, even at a feather edge.
