Usage

Miracote MiraPrime ML is used to seal new or existing concrete, prior to the application of polymeric flooring, polymeric decking or conventional flooring products.

Installation Steps

• Shot-blast and clean all concrete surfaces removing grease and loose debris.
• If concrete surface is damp, remove puddles, but leave concrete damp for MiraPrime ML application.
• Mix A and B components of MiraPrime ML together.
• Apply MiraPrime ML in a thin film with a short nap roller (1/4” nap roller). Do not build film of the primer, but roll out so that it soaks into the surface. Two coats of primer may be necessary on porous surfaces to insure uniform coverage.
• When primer turns from cloudy to clear, it is possible to apply a water-based topcoat.
• If applying a 100% solids epoxy topcoat, allow MiraPrime ML to cure for four hours minimum before applying topcoat. Do not exceed 36 hours on the re-coating of the MiraPrime ML. If 36 hours is exceeded, an additional application of MiraPrime ML is required. 6 to 24 hours is the optimum re-coat time.
• Depending on the porosity of the concrete, the coverage rate of MiraPrime ML is between 325 and 375 square feet per gallon for one coat. Over extremely porous surfaces, a second coat may be necessary.
