Prior to installing Concrete Resurrection CR-545 Inside Matte Urethane, a primer coat of Concrete Resurrection CR-531 Inside Epoxy must be applied. Allow a minimum of 16 hours for Concrete Resurrection CR-531 Inside Epoxy to cure, then mechanically clean and abrade using a floor machine (buffer) with 80 mesh sanding screen prior to application.
Mixing Instructions
Pour a full pre-packaged kit of 2 parts of Part A to 1 Part of Part B together and mix well with slow speed mixing equipment such as a squirrel cage mixer for 2 minutes to completely mix the components. Be careful to not whip air into the mixture, and be certain to scrape the sides and bottom of the can to combine all molecules. Incomplete mixing or an off balance mixture will result in a coating that will remain soft forever.
Application Recommendations
Apply the mixed material by brush or roller to a primed surface with a 3/8” nap-3/4” nap shedless roller cover at a rate of 4-6 wet mils within the usable pot life time frame, as well as the recommended temperature and relative humidity guidelines listed. If continuous outgassing in the concrete is causing bubbles, re-roll the material using a cross rolling method before the material cures to reduce or eliminate air entrapment. If the material becomes thick while applying and sticking to the roller, stop applying and discard the mixed material. At this point it has reached the end of the usable pot life. While applying, keep a wet edge to prevent roller marks. It is recommended to work in sections usually using control joints or cut lines as dividers to ensure proper application results. Do not allow to Puddle! Remove any excess material in joints or low impressioned areas. Puddled areas may not cure adequately and may cause blush or a white haze. If recoating after 24-36 hours(depending on temperature) a light sanding using a fine sanding screen must be done.
