MiraPatch RM1
MiraPatch RM1 is a two-component, polymer-modified, cementitious, trowel-grade concrete repair mortar and high performance underlayment for Miracote and other subsequent finished flooring installations. Designed primarily for horizontal applications, MiraPatch RM1 can be applied from near feather up to 3/4” in thickness. It can also be used in vertical and overhead applications when repair methods using formwork are being utilized. For applications greater than 3/4” in depth, extend MiraPatch RM1 with coarse ¼” (3/4” to 1”) or 3/8” (>1”) clean aggregate to produce MiraPatch RM1 concrete which will enhance dimensional stability.

- Advantages
Low slump, trowel-grade consistency.; High abrasion resistance.; Excellent freeze/thaw & de-icing salt resistance.; Ideal trowel-applied mortar for horizontal surfaces.; Suitable for use in cast-in-place repair methods.; Two component – high polymer-to-cement ratio.; High compressive, flexural and tensile strengths.; Tenacious adhesion to prepared substrates.; Extendable with coarse aggregate for repairs > 3/4".; Zero VOC - contributes to LEED credits.; Meets USDA and FDA compliance standards.
- 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 1 as published.; 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 at all times 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 in order to meet published physical properties. Moist curing with burlap/polyethylene or burlene is the preferred method. A compatible waterbased 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. Job site visits by Miracote representatives are only for the purpose of making recommendations. Supervision and quality control are the sole responsibility of the user.; Measure surface and ambient temperatures to ensure that material is only applied when temperatures are 45° F (7° C) and rising during placement and time of application.
