DCP Cemflow Topping Pigmented

DCP Cemflow 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.
DCP 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.


A 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

Surface 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.

Application Instructions


Concrete and sand / cement screeds must be sound, dry and fully cured (not subject to shrinkage) and any laitance or 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.


It is not usually necessary to prime absorbent surfaces. However, to ensure satisfactory bonding, the prepared surface should be dampened down to minimise pinholing. Ensure that the surface is in a saturated surface dry condition i.e. no visible surface water, prior to application of Cemflow Exterior Topping.



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 105mm using a 35cc flow ring.


Use a power-whisk fitted in a heavy-duty slow speed electric drill. Mix in the proportion of 25kg of powder to 4.0 – 4.5 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.

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 of 5mm to 15mm in one pass only.

Maintaining a “wet edge” as you work will help to minimise natural colour variations that can occur between sections.

Extra water should not be added to the mix. If the material thickens before it is applied it should be discarded.

For thicker applications it is advisable to use the lowest recommended water addition level, to reduce the potential of surface laitance.

To lay Cemflow Exterior Topping to falls add sufficient water to reach a trowellable consistency.


Isolated areas up to 50mm in depth can be repaired by adding 12.5 kg of clean, dry, 3 – 6mm aggregate to a 25 kg bag of Cemflow Exterior Topping.


Cemflow Exterior Topping does not need to be sealed. However if extra protection is required, we recommend the use of Setseal 6.


Ensure that all joints subject to movement, i.e. expansion and isolation joints, are carried up through the Cemflow Exterior Topping and filled with a suitable joint sealant.

Once mixing and laying are complete, tools should be cleaned immediately after use with cold water.


Do not place when the substrate temperature is below 5°C or when the ambient temperature is 10°C and falling.

Do not apply in temperatures over 25°C. Protect from direct sun whilst applying and curing.

Do not apply in excessively windy conditions. Do not apply in rain or when rain is forecast.

Protect from frost.

Do not exceed the maximum recommended water content and only use clean potable water.

Do not apply to Tarmacadam or asphalt surfaces. Avoid cleaning with acidic cleaning solutions.
