Rapid Set LevelFlor is an advanced hydraulic cement-based self-leveling underlayment (SLU) that can be used both indoors and outdoors in wet and dry environments. LevelFlor rapidly levels, maintains workability for 30 minutes, and produces a flat, strong surface with high bond strength (3,000 PSI in 24 hours and 3,500 PSI in 7 days).
LevelFlor is quick setting, which minimizes downtime. Treated surfaces are ready for foot traffic in at little as 3-4 hours. Designed for fast track leveling applications, LevelFlor may be used for a temporary wear surface prior to installation of finished flooring. Treated floors can be covered with finished flooring in 6 to 16 hours at 70˚F (21˚C) depending on the flooring type.
This advanced underlayment can be applied from feather-edge to 1” (25 cm) thick and up to 5” (127 cm) thick when extended with aggregate.
LevelFlor is an excellent choice for new floor projects and repair projects. It's easy to use—just add water, mix, and place!
DO NOT BREATH DUST. AVOID CONTACT WITH SKIN AND EYES. Use product in well ventilated areas. Exposure to dust from this product may irritate eyes, nose, throat and lungs. Use a NIOSH/MSHA-approved (under 30 CFR 11) or NIOSH-approved (under 42 CFR 84) respirator. Contact with dry material or wet mixtures may cause severe chemical burns to skin and eyes.
Protect eyes with goggles or safety glasses with side shields. Cover skin with protective clothing. Use chemical resistant gloves. Do not allow dry material or wet mixture to get inside boots or gloves. Exposure by inhalation over an extended period or repeated periods of time may result in the development of pulmonary diseases including silicosis, and lung cancer. Seek medical treatment if you experience difficulty breathing while using this product.
In case of skin contact, immediately wash with soap and water. In case of eye contact, flush immediately and repeatedly with large quantities of water. If irritation or burn occurs, seek medical treatment. Proposition 65: One or more of the components contained in this product may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
Concrete substrates must be clean, sound, and free of oil, curing compound, dust, mastic, bond-breaker and any other material that prevents good bonding. Concrete should be free of hydrostatic pressure, and vapor emission rates should comply with the finished flooring manufacturer’s requirements.
Smooth concrete and hard troweled surfaces should 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 the substrate is not recommended. Surface must be dry, have a minimum temperature of 50˚F (10˚C), and be properly primed. Honor all moving joints and cracks.
Apply Rapid Set® Acrylic Primer to all substrate surfaces prior to placement. Following the application instructions stated on the primer product packaging.
Add one 50 lb (23 kg) bag of LevelFlor® to 4.5 - 5 quarts (4.2 - 4.7 L) of potable water. Do not exceed 5 quarts (4.7 L) of water. LevelFlor® may be mixed using a paddle mixer with a ½″ heavy duty drill with a minimum 650 rpm or by using an appropriate mixer and pump. Mix 3-5 minutes until the mixture is smooth and lump free. Avoid mixers that entrap large amounts of air. Mixed LevelFlor® should be used within 30 minutes at 70˚F (21˚C). Maintain material temperature above 50˚F (10˚C).
Prior to placement, confirm that the primer is completely dry, Pour or pump LevelFlor® onto the substrate up to a maximum thickness of 1″ (25 cm). Use a gauge rake, spreader or other tools to place the material. Use a 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 feather-edge to match existing elevations.
For thicknesses greater than 1″ (25 cm), extend each 50 lb (23 kg) bag of Rapid Set® LevelFlor® with 25 lb (11.4 kg) of clean, dry 3/8″ (9.5 cm) pea gravel. Place the extended material to ½″ (13 cm) below desired floor level and then place neat LevelFlor® or Rapid Set® TRU™ Self Leveling for the final ½″ (13 cm) within 24 hours. When extended with aggregate, LevelFlor® may be placed up to 5″ (127 cm) thick.
No curing is required under normal conditions of 70˚F (21˚C). If used in exterior applications apply a fine water mist to the newly hardened surface of 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.
Moisture insensitive flooring such as tile may be placed in as little as 6 hours. Moisture sensitive flooring may be placed after 16 hours. 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 wear surface for foot traffic in 3 to 4 hours and rubber wheel traffic in 24 hours at 70° room temperature. LevelFlor® is not designed to be a permanent finished floor surface. LevelFlor® may be used as a temporary wear surface over a moisture control system. Contact CTS Cement before using LevelFlor® as a wear surface over a moisture control system application.
