VFlowdur Primer TC is a three-component solvent free polyurethane resin adhesive primer for use as a bonding aid for polyurethane resin based screed compositions including Flowdur WR, CG, SC and Flowbulk. Flowdur Primer TC is designed to be tacky to enable trowel applied resin screeds to be applied wet on wet giving a monolithic bond.
Resin products should not be mixed or applied outside of the range of 10 - 25 °C. The substrate and uncured floor must be kept at least 3°C to reduce the risk of condensation or blooming on the surface, from before priming to at least 48 hours after application.

Pack Size

2.10 kg units comprising of: Polyurethane Resin, Hardener and Aggregate components.

Coverage*

Coverage varies widely due to the porosity and profile of different substrates. As a guide, a coverage rate of 2.5 - 4 m2/kg should be estimated per coat depending on substrate quality.
*Coverage figures given are theoretical. Practical coverage rates may vary due to wastage factors and the type, condition, profile and porosity of the substrate.

Typical Properties, 28 days at 20 °C

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

Pot Life

2.10 kg units comprising of: Polyurethane Resin, Hardener and Aggregate components.

Cure Schedule @ 20 °C*

Working life of full packs* - 15 minutes
Finished floor*

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


Application Conditions:

Resin products should not be mixed and laid outside of the range 10 °C to 25 °C. Localised heating or cooling equipment may be required outside this range to achieve ideal temperature conditions. To reduce the risk of “blooming” caused by condensation, the climate above the uncured floor should be maintained at least 3°C above the dew point until subsequent toppings are applied.

Mixing:

Prior to mixing, the temperature of the three components must be between 15 and 25 °C. Pre-mix the 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. Add the full contents of the filler bag slowly and mix for a further 1-2 minutes until a lump free consistency is obtained. Care should be taken to ensure that any material adhering to the sides and bottom of the mixing vessel is thoroughly mixed in otherwise uncured patches may result.

Important: All components are pre-weighed and designed to be mixed together in their entirety. It is essential that the full amounts are mixed together and until homogenous to ensure the product cures correctly and to the desired finish.

Application:

Once mixed the primer should be applied immediately in a continuous film. Work the primer into the surface using a stiff brush, roller or trowel avoiding pooling. On porous surfaces Flowdur Primer TC will be absorbed leaving dry patches. A second coat should be applied to these dry areas to ensure good adhesion and reduce the possibility of air release from the substrate causing bubbles or pin holing in the final topping.
