![]() CONCRETE LEVELER may be used as an underlayment in moisture control systems. CONCRETE LEVELER is not designed to be a permanent finished floor surface. To determine if CONCRETE LEVELER is suitable for your specific application, install and evaluate jobsite test sections using the prepared substrate and the specified finished floor.ĬONCRETE LEVELER may be used as a temporary work surface for foot traffic in 2 to 4 hours and rubber wheel traffic in 24 hours at 70☏ (21☌). CONCRETE LEVELER is not designed to function as a vapor barrier. Always follow the flooring manufacturer’s recommendations for Moisture Vapor Emission Rate and retained moisture. ![]() Allow CONCRETE LEVELER to cure for 16 hours prior to installing moisture sensitive flooring such as some adhesives and coatings. Avoid excessively dry, windy, hot or sunny conditions.įLOOR COVERINGS: Ceramic tile may be placed in as little as 4 hours and other moisture insensitive flooring may be placed in 6 hours. If used in exterior applications, apply a fine water mist to the newly hardened surface of CONCRETE LEVELER as soon as it can be done without marring the surface. CONCRETE LEVELER can be troweled to a featheredge to match existing elevations.ĬURING: No curing is required under moderate conditions of 70☏ (21☌). A smoother trowel may be used to smooth the material. Use a Rapid Set® Spiked Roller to remove any entrapped air. Use a gauge rake, spreader or other tools to place the material. PLACEMENT: When primer is completely dry, pour or pump CONCRETE LEVELER with a minimum thickness of 1/8" (3 mm) over the highest point. Maintain material temperature between 60☏ and 80☏ (16☌ and 27☌). Mixed CONCRETE LEVELER should be placed within 20 minutes at 70☏ (21☌). Avoid mixers that entrap large amounts of air. Mix 3 to 5 minutes until the mixture is smooth and lump free. CONCRETE LEVELER may be mixed using a drill-mounted paddle mixer, or by using an appropriate mixer and pump. MIXING: Add one 50-lb (22.7-kg) bag of CONCRETE LEVELER to 4.5 to 5 quarts (4.3 L to 4.7 L) of potable water. When extended with aggregate, CONCRETE LEVELER may be placed up to 5" (12.7 cm) thick. For thicknesses greater than 2" (5.1 cm), extend each 50-lb (22.7-kg) bag with 25 lb (11.3 kg) of clean, dry 3/8" (0.95 cm) pea gravel. Follow the application instructions stated on the primer product packaging.ĪPPLICATION: Apply CONCRETE LEVELER up to 2" (5.1 cm) thick. PRIMING: Apply Rapid Set® Concrete Leveler™ Primer to all substrate surfaces prior to placement. ![]() Surface must be dry and be between 50☏ and 90☏ (10☌ and 32☌), and be properly primed. Mechanical methods of surface preparation, such as shot blasting, are preferred. Smooth concrete and hard-troweled surfaces must be prepared to achieve a surface profile similar to ICRI CSP 3. ![]() Concrete vapor emission rates should comply with the finished flooring manufacturer’s requirements. SURFACE PREPARATION: Substrate must be clean, sound concrete that is free of gypsum compounds and all materials that may inhibit bond such as: oil, curing compound, dust, mastic, bond breakers, and other surface contaminants. Contact your Rapid Set representative for LEED values and further environmental information. Production of Rapid Set cement emits far less CO2 than portland cement. CONCRETE LEVELER is an excellent choice for new floor projects and repair projects.ĮNVIRONMENTAL ADVANTAGES: Use CONCRETE LEVELER to reduce your carbon footprint and lower your environmental impact. Use to level or change the elevation of your substrate prior to installing carpet, tile, hardwood, or resinous flooring. CONCRETE LEVELER is ideal for all floor projects that need long flow life and working time while achieving high 24-hour strength. USES: Use CONCRETE LEVELER when a high quality, fast-setting, self-leveling underlayment is needed. Professionals choose CONCRETE LEVELER for self-leveling floor underlayment applications when a fast, durable and economical solution is required. This advanced underlayment can be applied up to 2" (5.1 cm) thick and up to 5" (12.7 cm) thick when extended with aggregate. CONCRETE LEVELER is designed for fast-track leveling applications and can be covered with finished flooring in 4 to 16 hours at 70☏ (21☌), depending on the flooring type. CONCRETE LEVELER has a flow life of 15 minutes, maintains workability for 20 minutes and produces a flat, strong surface with high bond strength. DESCRIPTION: Rapid Set® CONCRETE LEVELER® is an advanced hydraulic cement-based self-leveling underlayment that can be used both indoors and outdoors. ![]()
