Product Description: OBP Self Leveler - U16 & U24 - are water resistant, state of the art, cement based underlayments for interior and exterior applications. Both are designed to provide a durable, level floor surface with a minimum of labor and installation time. OBP Self Leveler will not shrink, crack or spall. Floor covering can usually be installed within 3-6 hours. Uses: New or Old Concrete Wood Terrazzo Ceramic Tile Cutback Adhesive Tile

Advantages:

• Not Gypsum Based
• Interior or Exterior
• Fast Setting System
• Trowelable or Self Leveling
• Water Resistant
• Non Shrinking
• Pumpable

Typical Test Results:

Compressive Strength: typically exceeds 5000 psi.

Coverage: 1 50# bag of OBP Self Leveler will cover approximately 50 sq. ft. at 1/8" thickness. 1 gallon OBP FL Primers diluted 1:1 will cover approximately 300-sq. ft. over smooth concrete.

Packaging: OBP Self Leveler is packaged in 50# paper sacks. OBP FL40 & FL50 Primers are available in 1 gallon and 5 gallon containers.

Surface Preparation: Gypsum, asphalt, coal tar and most lightweight concrete are not suitable substrates. If there is any doubt about the suitability of the subfloor a OBP Technician should be contacted. All subfloors must be cleaned, dried, and properly primed for a successful application. Substrate temperature must be a minimum of 50 F. Always install a test area to determine suitability of the system.

Priming: Interior applications require OBP FL40 Primer - Exterior applications require OBP FL50 Primer. Apply primer in a thin even coat using a brush or broom. Extremely porous concrete may require two coats. Do not use paint rollers, mops or spray equipment. If multiple layers of leveler are installed, each layer should receive primer.

Applications: Concrete - Floors must be sound, fully cured, free of moisture, efflorescence, oil, curing agents, sealers, and any contaminant which could act as a bond breaker. Unsound surfaces requiring cleaning should be done by mechanical methods - shotblasting, scarifying or similar. Acid etching is not an acceptable means of cleaning the substrate.

Non-porous Floors: Marble, terrazzo and ceramic tile must be solid and well bonded to the floor. These surfaces must be cleaned of any waxes or contaminants and primed with OBP FL50 Primer.
Plywood and Wood - Substrates shall be of exterior grade and shall provide a clean, rigid, secure base. Spacing between plywood sheets should be 3/16" to ¼". For floors receiving a tile finish, nail or staple thin galvanized metal lath to the wood before applying OBP Self Leveler.

Thickness of Application: OBP Self Leveler may be installed from a feather edge to 1" neat and up to 5" with the addition of a clean and well graded aggregate. When adding aggregate add 1/3 to 1 part by volume. DO NOT USE SAND. If aggregates are wet, the amount of water must be reduced. The addition of aggregate will diminish workability and may require the installation of a finishing layer.

Mixing: For hand applications, mix no more than two bags at a time. 1 50# bag of OBP Self Leveler requires 5 quarts of potable water. DO NOT OVERWATER. Put all of the mixing water into the mixing container first. Add the Floor Leveler and mix thoroughly with a heavy-duty drill and non-air entraining mixing paddle. OBP Self Leveler may be mixed and pumped using Chemgrout or Airplaco Pumps.

Placing Always install several test areas to ensure suitability. Pour the thoroughly mixed material on the floor and spread using a spreader. Immediately smooth the material using a finishing blade. Sufficient material should be used to cover all high points. Wear spiked shoes when walking in the wet material. Protect the poured floor from extreme weather conditions just as you would any concrete placement. The finished floor should be ready for foot traffic in 1 hour and floor covering in 3 - 6 hours. Weather conditions and substrate temperatures can affect these cure times.
