The product requires proper substrate preparation, priming with PP 600, and careful mixing with water at specific ratios to achieve optimal performance and coverage." tags: "concrete-flooring, self-leveling-compound, industrial-coating, technical-specifications, construction-materials, surface-preparation, cm960" key_entities: "Combimix AB (organization), Bålsta (location), CM960 Industrial Super Top (technology), PP 600 primer (technology), self-leveling compound (concept), calcium aluminate (concept)" classification: "reference" content_hash: "sha256:104c83c885457cdff70232999f518b71a6a8c6d16fca96494608fb8d99579bb3" acp_version: "0.2" token_counts_approximate: 1930 visibility: public agent_accessible: true status: "final" --- # Combimix_CM960_PDB_US Combimix datasheet Combimix AB • Verkstadsvägen 6 • SE - 746 40 Bålsta • Tel. +46 (0)171-46 65 90 • info@combimix.com Technical information Compressive Strength (ASTM C-349-02) 4,350 psi Flexural Strength (ASTM C-348) 1,087 psi Fire standard (EN 13813) A1 fl RWA – Tensile Bond Strength > 217 psi Surface Tensile Bond Strength (7 days) > 217 psi Surface Concrete Pour depths 3/8”–3/4” (10-20 mm) Weight (dry state) 118 lbs/ft 3 Weight (cured state) 148 lbs/ft 3 Ideal Slump max 4 1/2” Working time 15–20 min Final set 1–3 hrs pH (wet state) approx. 11 Water damage resistant yes Shrinkage (ASTMC-426-99) 0.03–0.05 % Emissions (ISO 16000-10 [indoor air quality part 10]) < 10 μg/(m² h) Coverage per 44 lb (20 kg) bag 1/4 ” thickness (approx. 6 mm) approx. 18,5 sq ft (1.8 m²) 1/2 ” thickness (approx. 12 mm) approx. 9,75 sq ft (0.9 m²) Area of use CM 960 Industrial Super Top is a premium quality pumpable, highly abrasion resistant,industrial self-leveling compound. The product is intended for both interior and exterior use on substra - tes of concrete. Top coating is recommended for aesthetics and stain reduction, however, is not necessary where aesthetics are not important, such as warehouse applications. CM 960 Industrial Super Top accepts direct application of most professional coatings, such as acrylic, polyurethane, polyurea, fluorosurfactant penetrating sealers, and epoxy-based systems as well as Terrazzo. CM 960 may also be grinded, polished and pigmented both topically and integrally. Pre-treatment The substrate should be clean and free of dust, cement skin, grease and other impurities that can prevent adhesion. Adhesion and surface resistance of the substrate should be no less than 217 psi (1.5 MPa). Control joints, construction joints and cracks in the substrate which may be subject to movement after installation of CM 960 Industrial Super Top must be honored and maintained as joints in the new surface. If Calcium Chloride moisture testing of the substrate is to be performed, it must be done prior to the application of CM 940 as a false high reading will occur due to the tests being inaccurate on calcium aluminate leveling compounds. Always prime the substrate with PP 600 and allow to dry before pouring (see PP 600 datasheet for proper dilution and installation directions). In terms of the primer forming a film, the temperature of the substrate must not be below 50 °F. For best results, the ambient temperature in the work area should be between 50 and 77 °F. At higher or lower temperatures, the time for curing will shorten or extend. Protect the product from excessive heat, excessive cold and draft conditions during and after the installation. It is recommended that the installation should be done with a proper air ventilation from an HVAC system. With the risk for cracks due to shrinkage or settings in the subfloor, a concrete surface should not be leveled within the first 28 days after casting. As a recommendation the RH in the concrete should have reached RH 90 % as the upper limit for pouring the CM 960. Use the Combimix form foam for edging. In order to avoid drainage pipes from getting clogged, always make sure the drains are properly sealed before pouring. Mixing Mix the dry powder with max 3.2 qt (3.0 l) of water, max 15 %, per 44 lb (20 kg) bag. Manual mix: Mix with a heavy duty ½” (13 mm), 650 rpm minimum drill and a whisk to obtain a lump free consistency. Mixing pump: Mixing pump intended for this purpose. Start pump at minimum of 120 gallons of water per hour and adjust as necessary to yield a self-leveling consistency. Please note that the production capacity and speed of the pump will dictate the gallons of water ratio per hour. The Combimix slump test must always be carried out to ensure the product performance and that the mixture is homogenized and free from separation. The correct water mixture can be tested using a slump test with a cylinder with Ø 1.18” and a height of 1.97” (Ø 30 mm and a height of 50 mm) on 11.8” x 11.8” (300 x 300 mm) plexiglas plate. With the correct water mixture, the spread should be max 4 1/2” (115 mm) for application thickness 3/8”–3/4” (10–20 mm). The slump test also checks that the material is well blended and that there is no separation. Application The mixed material is applied by hand, or pumped out onto the substrate in lengths. Each new ribbon is added to the old one as soon as possible so that the material can blend together and create an even surface. The width of the ribbons can be adjusted to the capacity of the mixing pump and the thickness of the covering. Set thickness using a Gauge Rake and smooth the mixed material using a spike roller or a toothed trowel. Working time of the product is appx. 15 to 20 minutes. Application thickness 3/8”–3/4” (10–20 mm). Post-treatment and curing You can easily shape or cut the semi-hardened self-leveling underlayment material before it fully dries. Protect the surface for up to 24 hours after installation. Material can be walked on after 1–3 hours. The product is paintable with epoxi or similar after 3–5 days depending on the thickness. Sealers should be applied to reduce topical staining and must be used for applications where aesthetics are important. The guiding value assumes a curing temperature of approximately 68 °F, 40 % RH and proper air flow.
