LIGHT

SELF-LEVELLING FLOOR TOPPING
 

Advantages:

  • Fast Drying Technology:                                                   Foot Traffic in 3 hours

  • Low Odour & Protein Free:                                                      Suitable for Use in Biologically Sensitive Areas

  • Very Good Abrasion Resistance:                                              AR 1,0 / BS EN 13892-4

Description:

Cemflow Light is designed as a light duty floor topping for upgrading and renovating new and existing internal floors.

Usage

Cemflow Light is supplied as a pre-blended dry powder designed for application between 3mm to 6mm or can be filled to 10mm (in one application) to provide a finished floor for foot traffic.

Cemflow Light is self-smoothing, dimensionally stable, and fast drying. It is suitable for use in a wide range of applications. It is also protein free so may be used in biologically sensitive areas.

We would recommend that Cemflow Light be sealed in areas where water may come into direct contact with the cured material. Cemflow Light may be sealed with Strongcoat WD water based epoxy coating, or if a matt finish is required, apply a first coat of clear Strongcoat WD followed by a coat of Strongcoat Matt Clear. Cemflow Sealer can also be used to seal the product in a commercial environment. (Further information is available from our Technical Department or the Product Data Sheets).

Materials Supplied 

25Kg paper sacks.

Coverage

A 25kg bag using 5 litres of clean water will yield approx. 14.4 litres.

A 25kg pack of Cemflow Light will cover approximately 4.8m² at 3mm thickness.

Storage

Protect from frost and store under dry warehouse conditions at a temperature between 10°C and 30°C.

Shelf Life

6 months in unopened bags and stored under good conditions.

Application Instructions

SURFACE PREPARATION

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

For uneven surfaces, apply Cemflow Base to a minimum 5mm to provide a smooth level surface, prior to the application of Cemflow Topping (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.

Prior to application on to impervious surfaces the area should be thorougly cleaned and lightly scarified. Any existing surfaces should be well bonded (>1.5N/mm²).

The perimeter of the room and any columns should be isolated using a compressible strip.

For application over underfloor heating please contact DCP Technical Department for specific advice.

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.

MIXING - HAND APPLICATION

Use a power-whisk fitted in a heavy-duty slow speed electric drill. Mix in the proportion of 25kg of powder to 4.5 – 5.0 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 of 5mm to 15mm in one pass only.For the application of any seal coats, please refer to relevant Technical Data Sheets.

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 10ºC 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.
