Product Description
LEVEL TOPPING is a premium, cement-based, nonshrink, self-leveling interior floor topping designed as a wearing surface. It only requires the addition of water to produce a flowable mixture that can be poured or pumped onto the floor. It can be used to level or create a solid surface on interior industrial type concrete floors. This product can also be used on new construction projects to correct rough or unfinished concrete and to level out uneven floors. On restoration projects, LEVEL TOPPING can be used to produce a hard, even finish over old concrete.

Directions for Use
Surface Preparation: To prepare surface, follow all standard ACI and ICRI recommendations. Remove all dirt, gas, oil, grease, carpet, adhesives, asphalt, paint, curing compounds and all loose surface materials. All cracks must be repaired and filled. Cracks that exhibit movement must be either left open through the topping or repaired in such a way as to stop the movement. Any and all control, expansion or other joints must not be filled with this product. Do not use this product on painted or sealed surfaces.
Water Requirements: 4 quarts of water per 50-pound bag. DO NOT overwater, as that can cause segregation and a weak surface.
Mixing: Pour 4 qt of water into a mixing container, then add one 50-pound bag of LEVEL TOPPING. Never use more than 4 qt of water for mixing per bag. With a blending paddle attached to a heavy-duty electric drill (650 rpm), mix for 2-3 minutes until mixture is smooth and free of lumps. For pumping applications, mix for 1-2 minutes in the pump’s mixing tank. Do not overwater or retemper. It can be extended by adding 15 lbs. of 3/8 in. pea gravel for each 50 pounds of product. this is required in layer areas over 1 1/2 in. thick. First, mix LEVEL TOPPING as per earlier instructions, then during the last minute of mixing, add the required aggregate. Should a finish coat then be required, apply a nonextended layer of LEVEL TOPPING after the first pour becomes walkable. Reprime the first pour with another application of the bonding agent.
Priming: Prime concrete surface with Level Primer J42 using a brush or broom. Allow the primer to dry completely to the touch before proceeding (2-3 hours at 70°F and 50% relative humidity). Do not wait longer than 72 hours. Refer to the primer data sheets for complete instructions.
Placement: Pour LEVEL TOPPING over the substrate spreading the material with a long-handled spreader. The product can be pumped using an appropriately sized grout pump. No troweling is necessary. The product will level itself during the first 15 minutes at 70°F (21°C) and will accept foot traffic approximately 4 hours after installation. Do not install LEVEL TOPPING when the surface and ambient temperature is less than 40°F (4°C). During hot weather, reduce the size of the work area, keep bags of material cool prior to mixing and use cold water for mixing. Not recommended for application if air, substrate or material temperatures are above 90°F (32°C) as work time, flow and leveling properties will be diminished. Protect from winds until material has reached final set.
Clean Up: Use water prior to material hardening. After material has hardened, abrasive methods are required.
