Flowdur Cove Grade

Flowdur Cove Grade is a lightweight trowel applied material based upon a liquid polyurethane resin system. It creates a seamless hygienic skirting and is designed specifically for use with Flowdur polyurethane flooring in order to maintain the same standards of resistance to abrasion and chemical contact.

Appearance

Lightly textured matt finish.

Thickness

Typically 2-9mm thickness with a maximum height of 300mm.

Coverage

100mm x 50mm x 6mm cove (2" radius) - 4.86 linear metres per pack. Approximately 2kg/m2 per mm thickness when applied flat.

Chemical Resistance

Flowdur CG is resistant to a wide range of commonly used chemicals in the food, dairy and pharmaceutical industries such as concentrated citric acid (fruits), spirit vinegar (50% acetic acid), lactic acid (food & dairy products) and common alcohols (methanol & ethanol). Flowdur CG is also resistant to a wide range of inorganic acids, fuels, hydraulic oils, mineral oils and solvents. For maximum chemical resistance, Flowdur CG should be fully sealed with an appropriate Virtus product such as Flowdur TF. Good housekeeping practices should be employed. Please consult our Technical Department for further advice. Some staining or discolouration may occur with some chemicals, depending on dwell time, temperature, type of chemical and degree of housekeeping employed. This does not affect the product service integrity or durability.

Temperature Resistance

Flowdur CG is resistant to cleaning temperatures up to 60°C when applied at a minimum of 4 mm thickness.

Typical Properties, 28 days at 20 ºC

Adhesion to concrete (BS EN 1504-2) > 1.5 MPa

(concrete failure)

The typical physical properties given above are derived from testing in a controlled laboratory environment. Results derived from testing field applied samples may vary dependent upon site conditions. The slip resistance figure given above are affected by application techniques and prevailing site conditions. Slip resistance can reduce over time due to poor maintenance, general wear or surface contaminants. Good housekeeping practices should be observed.

Cure Schedule at 20 ºC

Working life of full packs: 15 minutes * (Usable working life of material following mixing and immediate spreading as per the application instructions)

Overcoating with Flowdur TF: 24 hours*

Cure time to light pedestrian traffic 12 hours*

Cure time to light wheeled traffic: 24 hours*

Cure time to heavy duty traffic: 48 hours*

Full chemical resistance 7 days*

*The above cure times are approximate and given as a guide only. These times can vary due to prevailing site conditions.

Pack Size: 16.30 kg

Application Conditions

Ideal ambient and substrate temperature range is 15 - 25 ºC. Localised heating or cooling equipment may be required outside this range to achieve ideal temperature conditions. The aggregate can be stored in a cool area (or warm area in the case of low ambient temperature) in order to control product temperature and working life. The substrate and uncured floor must be kept at least 3 ºC above the dew point to reduce the risk of condensation or blooming on the surface, from before priming to at least 48 hours after application.

Surface Preparation

Inadequate preparation will lead to loss of adhesion and failure. Substrates should be clean, dry, sound and free of surface laitance. See the Virtus Guide to Surface Preparation for further information.

Priming

Flowdur CG should be applied into tacky Flowprime TC (typically 45 - 60 minutes after application). If, prior to application of Flowdur CG, there are dry patches, a further coat of Flowprime TC primer is required. If the primer has been left to cure for >48 hours then the primer surface should be mechanically abraded and the area re-primed.

Application of Flowdur CG

Prior to mixing, the temperature of the three components must be between 15 and 25 oC. Pre-mix the coloured resin component before use. Add the hardener component to the coloured resin component and mix using a low speed electric mixer (300 - 400 rpm) for 1 - 2 minutes until homogeneous. Decant the mixture into a rotary drum mixer and add the aggregate component in stages, mixing for a minimum of 3 minutes until a uniform coloured, lump-free mix is obtained. Apply the mixture immediately onto pre-primed areas using a coving trowel to form skirting if required. Avoid excessive tooling which may lead to ‘trowel burn’.

Sealing

Due to the dry nature required of a product designed to be applied vertically, Flowdur CG shows a lower colour strength than flooring materials and colour density may vary throughout an installation. Where a closer colour match is required or where Flowdur CG requires sealing, for example, in wet areas or where chemical spillages are likely, Flowdur TF should be applied within 24 hours of application. See separate technical datasheet.

Cleaning

Regular cleaning is essential to enhance and maintain the life expectancy and appearance of the product. Flowdur CG can be easily cleaned using industry standard cleaning chemicals and techniques, especially where sealed using Flowdur TF. Consult your cleaning chemical and equipment supplier for more information.

EU Directive 2004/42/EC : Complies with category j type SB (< 500 g/l). The VOC content of Pumadur CG is approx. 6 g/l (theoretical).

Storage

Store off the ground in un-opened packs in a dry store, under cover between 10ºC and 30ºC out of direct sunlight. Protect from frost.

Shelf Life

Resin and hardener components 12 months Aggregate component 6 months. If stored in accordance with the above recommendations

Limitations

Do not proceed with application if atmospheric relative humidity is, or is anticipated to be, >90% or if the surface temperature is <3 ºC above the dew point. Application should not commence when the substrate temperature or the ambient temperature is, or is anticipated to be <5 ºC during the application or within the curing period. The design strength of concrete surfaces must be a minimum of 25 MPa compressive strength at 28 days. The manufacture of Flowdur CG is a batch process and despite close manufacturing tolerances, colour variation may occur between batches. Products from different batches should not be used on the same surface or surfaces close together. If mixed batches are unavoidable, it is best practice to use the different batches only in areas where the colour cannot be directly compared. Touching up should only be attempted using product from the same batch using the same application methods. Product should be reserved specially for this purpose. It is recommended that touching up is carried out up to a break in the floor or surface.
