MiraPatch RM 3000
MiraPatch RM 3000 is a single component, polymer-modified, pre-blended cementitious repair mortar fortified with micro-fiber reinforcement and shrinkage-compensating additives to achieve exceptional physical properties with very low drying shrinkage. Designed for horizontal and vertical applications, MiraPatch RM 3000 can be troweled-applied at a minimum depth 1/8” up to 1”. For repair depths 1” and greater, extend mortar with 3/8” clean coarse aggregate to produce MiraPatch RM 3000 concrete.

- Advantages
Polymer modified powder – no need liquid latex admixture.; High early strength – 2,200 psi in 4 hours.; Rapid return to service for fast track installations.; Low free water content – can be coated in 6 hours.; Very low water absorption and drying shrinkage.; Excellent compressive, flexural and tensile strengths.; Tenacious adhesion to prepared substrates.; Excellent freeze-thaw resistance.
- Limitations
Concrete surface repair dimensions including overall length, width, depth and shape need careful consideration, and should be in conformance with ACI recommended standards of practice.; Mechanical surface preparation methods may require additional testing to verify substrate tensile strength in accordance with ICRI Guideline No. 210.3R-2013 (Guide for Using In-Situ Tensile Pull-off Tests to Evaluate Bond of Concrete Surface Materials).; Extension with coarse aggregates may alter the physical properties of MiraPatch RM 3000, as published herein.; Do not use solvent based curing compounds.; As with all cement-based materials, avoid direct contact with aluminum to prevent an adverse chemical reaction. Refer to MiraPrime AL for an appropriate primer.

- For Best Results
Always install a minimum 4' by 4' test area or job site mock up for owner approval of acceptable color, texture, finish adhesion and any other critical requirements prior to proceeding with the installation.; Verify that the most current versions of product technical data sheets (PTDS), color charts, material safety data sheets (MSDS), and installation guidelines (IG) are being utilized for project submittals and application reference.; Protect materials always from excessive heat and cold, and pre-condition material as required in adverse conditions.; As per ACI recommendations for Portland cement concrete, curing is required to meet published physical properties. Moist curing with burlap/polyethylene or burlene is the preferred method. A compatible water-based curing compound is also acceptable but may require removal prior to the application of subsequent coatings or other materials.; The proper application of this product is the sole responsibility of the end user. The intent of job site visits by Miracote representatives is for observation of the work and offering technical recommendations only. Supervision and quality control are the sole responsibility of the user.; Measure surface and ambient temperatures to ensure that material is only applied when both temperatures range between 40°F (7°C) and 90°F (32.2°C) during mixing, placement and time of application.; When applying resinous and other moisture sensitive coatings after only 6 hours of cure, perform in-situ tensile pull-off tests to evaluate bond and confirm acceptable adhesion to the MiraPatch RM3000.
