CR-546 Inside High Gloss WB Urethane
Concrete Resurrection CR-546 Inside High Gloss Urethane is the ultimate solution for those looking to elevate the aesthetic appeal and durability of their concrete surfaces. Formulated as a two-component water-based aliphatic polyurethane, this high gloss urethane not only enhances color but also provides a robust finish that withstands the test of time. Whether you’re revamping your garage, showroom, or office, this versatile product promises excellent adhesion and impressive hardness, ensuring long-lasting protection against abrasion, hot tires, and various chemicals.
Each 2.5 Gallon Kit covers an impressive 500 to 700 square feet, catering to a variety of interior applications. Ideal for fully cured concrete surfaces—typically requiring 28 to 45 days of cure time—CR-546 is specifically designed for porous substrates that have been meticulously cleaned of dirt, oil, dust, and other contaminants. Its low VOC and low odor formulation offer a user-friendly experience, making it a perfect choice for residential and commercial spaces alike.
Once applied, light foot traffic can resume in just 16 to 20 hours, while full curing occurs within 4 to 7 days, allowing for minimal disruption to your routine. However, users are advised to consider safety, as the surface may be slippery when wet. The innovative nature of the CR-546 formulation also means that excessive buildup should be avoided to achieve the best results.
For optimal application, referencing the technical data sheet is recommended to ensure a flawless finish. Note that this product should not be used on brick surfaces, maintaining its focus on enhancing the beauty and resilience of concrete. Transform your spaces with CR-546 and enjoy a stunning, high gloss look that lasts.
Coverage rate is: First Coat: 200 - 300 sq ft per gallon. Second Coat: 250 – 350 sq ft per gallon
Coverage variations depend on concrete surface porosity, texture and amount of material applied. Excessive build up should be avoided.
For a thin film build system (2-3 mils) we suggest either mechanical scarification, acid etching (and the neutralize to 7 PH), or diamond grinding until an appropriate profile is accomplished. To ensure adequate adhesion, the substrate must be free of all dirt, oil, dust, and foreign contaminants.
Refer to technical data for complete instructions.
Mixing Instructions
If mixing less than a full kit, mix Part A only separately by vigorously shaking container AND mix with a drill mixer for 2-3 minutes prior to blending the smaller kit to ensure uniform distribution of all ingredients (drill mixer must be used, not a stir stick). Failure to do so may result in craters/fish eyes. Pour a full pre-packaged kit of 4 parts of Part A to 1 part of Part B together and mix well with slow speed mixing equipment such as a jiffy mixer for 2-3 minutes or until the material is thoroughly mixed and homogenous. Water based two part systems need to be mixed well for adequate cure and a streak free finish.
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.
