UsageCemflow
Topping Pigmented is supplied as a pre-blended dry powder designed for
application between 5mm to 15mm (in one application) to provide a
finished hardwearing floor surface. Cemflow
Topping Pigmented is self-smoothing, dimensionally stable, and fast
drying. It is suitable for use in a wide range of industrial and
commercial environments such as schools, showrooms, galleries,
hospitals, factories, warehouses etc. subjected to medium to heavy
traffic. It is also protein free so may be used in biologically
sensitive areas. Cemflow
Topping Pigmented is suitable for application on to a wide range of
subfloor types, including; sand and cement screeds, concrete, terazzo,
granolithic, epoxy and polyurethane resins and waterproof membranes. Typically
Cemflow Topping Pigmented can be pumped up to 1500m² per day. Coverage
of 600m² can be achieved when hand applied, dependent upon manpower and
equipment used. We
would recommend that Cemflow Topping Pigmented is always sealed with
Cemflow Sealer. (Further information is available from our Technical
Department or the Product Data Sheets). Materials Supplied20 kg and 25 kg paper sacks CoverageA 20kg bag using 4.00 litres of clean water will yield approx. 12.0 litres. A 20kg pack of Cemflow Topping Pigmented will cover approximately 2.4m² at 5mm thickness. A 25 kg bag using 5.0 litres of clean water will yield approx. 15.0 litres. A 25 kg pack of Cemflow Topping Pigmented will cover approximately 3.0m² at 5mm thickness StorageProtect from frost and store under dry warehouse conditions at a temperature between 10°C and 30°C. Shelf Life6 months in unopened bags and stored under good conditions. Technical Information

Application InstructionsSURFACE PREPARATION Concrete and sand / cement screeds must be sound, dry and fully cured (not subject to shrinkage). Any laitance, contamination and surface treatments must be removed by mechanical means such as grit blasting. The surface tensile strength of the substrate should be a minimum 1.5 N/mm². For uneven surfaces, apply
Cemflow Base to a minimum 5mm to provide a smooth level surface, prior
to the application of Cemflow Topping Pigmented. (Please refer to
relevant product Technical Data Sheets). The
concrete substrate should be below 75% RH alternatively Strongcoat DPM
should be applied. The temperature of the floor must be maintained above
10°C throughout the application and drying of the Cemflow Topping
Pigmented. PRIMING TO CONCRETE AND CEMENT SCREEDS For
application on to sand / cement screeds, concrete and other porous
substrates, first seal the prepared surface by applying one diluted coat
of Neoprene Primer, diluted one part Neoprene Primer with 4 parts
potable water by soft broom or brush, and allow to thoroughly dry. Apply
a second coat of primer diluted 3:1 by the same method and allow
thoroughly to dry. Depending on the porosity of the substrate a further
coat may be required. To confirm if this is necessary a small
application area should be undertaken to ascertain the correct priming
requirements. As an alternative, Strongcoat Primer may be used. PRIMING WITH STRONGCOAT PRIMER Apply one coat Strongcoat Primer and allow to cure. Apply 2nd coat and whilst still tacky fully blind with DCP Coarse Aggregate at approximately 3kg/m² until the surface is covered and no resin spots remain. The rate of application is approximately 3kg/m². Allow to dry fully overnight and remove excess aggregate before applying the Cemflow Topping. TO CURED CEMFLOW BASE For application over Cemflow Base apply Neoprene Primer diluted 3 parts water to 1 part Neoprene Primer by brush or soft broom and allow to dry thoroughly. Apply a further application of Neoprene Primer diluted 3:1 with water and again allow to dry thoroughly. TO IMPERVIOUS SURFACES For
application on to impervious surfaces, such as tiles, coatings or onto
Strongcoat DPM (please read relevant product technical data sheet).
Apply Strongcoat Primer and whilst it is still tacky fully blind with
DCP Coarse Aggregate at approximately 3kg/m², until the surface is
covered and no resin spots remain. Allow to dry fully overnight and
remove excess aggregate before applying the Cemflow Topping.MIXING PUMP APPLICATION Mix the powder and water according to the method recommended by the pump manufacturers. In the case of pumps having a continuous water feed adjust the rate of water flow until the mix is a smooth fluid, uniform grey liquid with no surface separation, producing a flow of approximately 130mm using a 35cc flow ring. HAND APPLICATION Use a power-whisk fitted in a heavy-duty slow speed electric drill. Mix in the proportion of 20kg of powder to 3.8 – 4.2 litres of potable water. Pour the water into a suitably sized bucket and gradually add the powder while stirring, until a smooth, lump free consistency is achieved. The material should be mixed for a minimum of 3 minutes. Leave to stand for 2-3 minutes and mix briefly for 1 minute before applying. APPLICATION Pour or pump the mixed material onto the prepared surface and allow to attain a smooth finish. The use of a spiked roller will help eliminate entrapped air and smooth out flow lines. Apply at a thickness between 5mm to 15mm in one pass only. We would recommend the first coat of Cemflow Sealer should be applied over the Cemflow Topping Pigmented a minimum of 6 hours after application. (Please refer to Cemflow Sealer Technical Data Sheet). CLEANING Wash tools with water immediately after use. PRECAUTIONS Do not place when the substrate temperature is below 10°C or when the ambient temperature is 10°C and falling. Protect from frost. Do not exceed the maximum recommended water content and only use potable cold water. This product is not recommended for external use or situations where water may come into direct contact with the cured material. This product should not be applied to ashpalt or bituminous surfaces. HEALTH AND SAFETY Refer to the product Material Safety Data Sheets before using Cemflow Topping Pigmented.
