- 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 (SDS), and installation guidelines (IG) are being utilized for project submittals and application reference.; Refer to all Miracote published documentation pertaining to MiraFlex II Decking System where MiraPatch LM is most typically used.; Protect materials at all times from excessive heat and cold before and during application.; Precondition liquid and powder components between 55°F(4.5°C) to 80°F(4.5°C) prior to mixing and application.; 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 installer.; Measure surface and ambient temperatures to ensure that material is only applied when temperatures are 40 F (4.5 C) and rising during placement and cure time.; Condition the concrete substrate with MiraPrime Aqua-Blok XL to minimize the potential for efflorescence migration and mitigate the corrosion of reinforcing steel at a 95% confidence limit as tested per the U.S. Bureau of Reclamation M-82 Standard Protocol to Evaluate the Performance of Corrosion Mitigation Technologies.
