TDS For Polyscreed PU
- Step by Step
Surface preparation
The concrete surface should thoroughly be cleaned of all loosely adhering particles, laitance, dust, oil, grease, paint, etc. Remove localized weak or deteriorated concrete and replace by sound concrete and structural repair materials. After surface preparation, all loose debris and dirt should be removed by vacuum equipment.
Priming
For weak and critical substrates, use our primer- POLYPRIME W in place of scratch coat so as to get better bonding. Leave the primer to be completely dry. If the primer is left for more than 24 hours before application of POLYSCREED PU, an additional coat of primer should be applied
Mixing
Pour the entire contents of Part A and Part D (colour pigment) in a mixing pot and mix it for 15 seconds, then add Part B to this mix and keep mixing it with a heavy duty paddle mixer fitted to a high torque slow speed (300-400/rpm) drill for a minute to get a homogenous mix. Then add Part C (powder) slowly into the mixture and further mix until a uniform consistency is achieved. Part mixing is not recommended.
Application
Pour the mixture of POLYSCREED PU on the floor. Spread the mix with a notch trowel uniformly to achieve the desired thickness of 4 to 6 mm. The material is to be rolled with a spike roller to release the entrapped air from the mix. The subsequent kit should be poured on the floor within the pot life of the first kit and should be spread and joints should be matched. The floor should be spike rolled and joint should be matched by rolling on the joint. Care should be taken not to take the spike roller on the earlier kit as the setting of the earlier kit has already started and taking spike roller on it can leave roller marks on the surface
Curing & Protection
At 30ºC, foot traffic access in 8 hours, vehicular traffic in 16 hours. At 20ºC, foot traffic access in 12 hours, vehicular traffic in 24 hours. Full cure at 28 days. Please refer detailed method statement which can be requested to local sales team.
