DESCRIPTION: Rapid Set® LEVELFLOR® is an advanced hydraulic cement-based self-leveling underlayment that can be used both indoors and outdoors. LEVELFLOR rapidly levels, maintains workability for 20 minutes and produces a flat, strong surface with high bond strength. LEVELFLOR is designed for fast track leveling applications and can be covered with finished flooring in 4 to 16 hours at 70˚F (21˚C), depending on the flooring type. This advanced underlayment can be applied from featheredge to 2" (5.1 cm) thick and up to 5" (12.7 cm) thick when extended with aggregate. Contractors and engineers specify LEVELFLOR for self-leveling floor underlayment applications when a fast, durable and economical solution is required.
USES: Use LEVELFLOR when a high quality, fast-setting, self-leveling underlayment is needed. LEVELFLOR is ideal for all floor projects that need long flow life and working time while achieving high 24-hour strength. LEVELFLOR is an excellent choice for new floor projects and repair projects.
ENVIRONMENTAL ADVANTAGES: Use LEVELFLOR to reduce your carbon footprint and lower your environmental impact. Production of Rapid Set cement emits far less CO2 than portland cement. Contact your Rapid Set representative for LEED values and more environmental information.
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. Concrete vapor emission rates must comply with the finished flooring manufacturer’s requirements. Smooth concrete and hard-troweled surfaces must be prepared to achieve a surface profile similar to ICRI CSP 3. Mechanical methods of surface preparation, such as shot blasting, are preferred. Acid etching is not recommended. Surface must be dry and be between 50˚F and 90˚F (10˚C and 32˚C), and be properly primed. Honor all moving joints and cracks.
PRIMING: Apply Rapid Set® Acrylic Primer to all substrate surfaces prior to placement. Follow the application instructions stated on the primer product packaging.
APPLICATION: Apply LEVELFLOR with a minimum thickness of 1/8” (3 mm) over the highest point and a maximum thickness of 2" (5.1 cm). 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. When extended with aggregate, LEVELFLOR may be placed up to 5" (12.7 cm) thick.MIXING: Add one 50-lb (22.7 kg) bag of LEVELFLOR to 4.5 to 5 quarts (4.3 L to 4.7 L) of clean, potable water. Do not exceed 5 quarts (4.7 L) of water. LEVELFLOR may be mixed using a 1/2" drill mounted paddle mixer or by using an appropriate mixer and pump. Mix 3 to 5 minutes until the mixture is smooth and lump-free. Avoid mixers that entrap large amounts of air. Mixed LEVELFLOR should be placed within 20 minutes at 70˚F (21˚C). Maintain material temperature between 60˚F and 80˚F (16˚C and 27˚C). PLACEMENT:
PLACEMENT: When primer is completely dry, pour or pump LEVELFLOR. Use a gauge rake to place the material. Use a Rapid Set® Spiked Roller to remove any entrapped air if necessary. A smoother trowel may be used to smooth the material. LEVELFLOR can be troweled to a featheredge to match existing elevations.
CURING: No curing is required under moderate conditions of 70˚F (21˚C). If used in exterior applications, apply a fine water mist to the newly hardened surface of Rapid Set® LEVELFLOR® as soon as it can be done without marring the surface and continue until one hour after final set. Avoid excessively dry, windy, hot or sunny conditions.
FLOOR COVERINGS: Ceramic tile may be placed in as little as 4 hours and other moisture insensitive flooring may be placed in 6 hours. Allow LEVELFLOR to cure for 16 hours prior to installing moisture sensitive flooring. Always follow the flooring manufacturer’s recommendations for Moisture Vapor Emission Rate and retained moisture. LEVELFLOR is not designed to function as a vapor barrier. To determine if LEVELFLOR is suitable for your specific application, install and evaluate jobsite test sections using the prepared substrate and the specified finished floor.
LEVELFLOR 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˚F (21˚C). LEVELFLOR is not designed to be a permanent finished floor surface. LEVELFLOR may be used as an underlayment in moisture control systems.
YIELD & PACKAGING: LEVELFLOR is available in 50-lb (22.7 kg) polyethylene-lined bags. Coverage is 24 ft2 to 30 ft2 (2.2 m2 to 2.8 m2) at 1/4" (0.6 cm) thickness and 12 ft2 to 15 ft2 (1.1 m2 to 1.4 m2) at 1/2" (1.3 cm) thickness for flat surfaces.
SHELF LIFE: LEVELFLOR has a shelf life of 12 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged package.
USER RESPONSIBILITY: Before using CTS products, read current technical data sheets, bulletins, product labels and safety data sheets at www.CTScement.com. It is the user’s responsibility to review instructions and warnings for any CTS products prior to use.WARNING: DO NOT BREATHE DUST. AVOID CONTACT WITH SKIN AND EYES. Use material in well-ventilated areas only. Exposure to cement dust may irritate eyes, nose, throat, and the upper respiratory system/lungs. Silica exposure by inhalation may result in the development of lung injuries and pulmonary diseases, including silicosis and lung cancer. Seek medical treatment if you experience difficulty breathing while using this product. The use of a NIOSH/MSHA-approved respirator (P-, N- or R-95) is recommended to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid ingesting cement dust. Skin contact with dry material or wet mixtures may result in bodily injury ranging from moderate irritation and thickening/cracking of skin to severe skin damage from chemical burns. If irritation or burning occurs, seek medical treatment. Protect eyes with goggles or safety glasses with side shields. Cover skin with protective clothing. Use chemical resistant gloves and waterproof boots. In case of skin contact with cement dust, immediately wash off dust with soap and water to avoid skin damage. In case of skin contact with wet concrete, wash exposed skin areas with cold running water as soon as possible. In case of eye contact with cement dust, flush immediately and repeatedly with clean water, and consult a physician. If wet concrete splashes into eyes, rinse eyes with clean water for at least 15 minutes and go to the hospital for further treatment. Please refer to the SDS and
