Rapid Set® CONCRETE LEVELER® is an advanced hydraulic cement-based self leveling underlayment that can be used both indoors and outdoors. This concrete self leveler has a flow life of 15 minutes, maintains workability for 20 minutes and produces a flat, strong concrete surface with high bond strength. The product features a compressive strength of 3000psi within 24 hours and 5,000 psi within a 28 day timeframe.


This self leveling concrete product is designed for fast-track leveling applications on almost any concrete slab 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 up to 2″ (5.1 cm) thick and up to 5″ (12.7 cm) thick when extended with aggregate. Professionals choose CONCRETE LEVELER for self-leveling floor underlayment applications when a fast, durable and economical solution is required.

This product is ideal for when you need an underlayment that is high quality and sets quickly. CONCRETE LEVELER is ideal for all floor projects that need long flow life and working time while achieving high 24-hour strength. The product is an excellent choice for new floor projects and when performing repair projects on old concrete floors.

Floor Coverings

You may cover the entire floor with a floor covering after using CONCRETE LEVELER. Ceramic tile may be placed in as little as 4 hours and other moisture insensitive flooring may be placed in 6 hours. Please be sure to allow the product to cure for at least 16 hours before installing flooring that is sensitive to moisture. Always be sure to abide by flooring manufacturer requirements for Moisture Vapor Emission Rate and retained moisture. CONCRETE 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°F (21°C). CONCRETE LEVELER is not designed to be a permanent finished floor surface. CONCRETE LEVELER may be used as an underlayment in moisture control systems


Use CONCRETE LEVELER to reduce your carbon footprint and lower your environmental impact. Production of Rapid Set cement emits far less CO2 than Portland cement. For more information, contact our friendly staff at Pantheon Surface Prep for LEED data.

Surface Preparation Details

When doing surface prep, the 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 should 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 prep, 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 Details

Apply Rapid Set® Concrete Leveler™ Primer to all substrate surfaces prior to placement. Follow the application instructions stated on the primer product packaging.

Product Application

Apply CONCRETE LEVELER up to 2″ (5.1 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. When extended with aggregate, CONCRETE LEVELER may be placed up to 5″ (12.7 cm) thick.

Mixing the Product

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. Do not exceed 5 quarts (4.7 L) of water. CONCRETE LEVELER may be mixed using a 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 CONCRETE LEVELER 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).
