APPLICATION  

Pre-application: ​

  • The strength of subtracting must be greater than or equal to 20 Mpa. It should be saturated but not contain water
  • Free from dust, contamination, all impurities, and grease.

Mixing:

  • Mixing slowly in the freshwater tank with a water mixing ratio is 12% (03 liters of fresh water for 25 kg) with a maximum speed of 400 rounds/mins for a duration of 05 minutes or until the mixture gets homogeneous. Stand by in one minute, then mix again before construction.

Application:

  • Use a brush or roller to apply BestBond EP759 (see technical data sheet of product) on the prepared surface above. The waiting time for applying the mortar of BestFloor PC302 is after 24h (depending on conditional temperature) when the layer of BestBond EP759 is dry. Pour continuously furrow and the width about 200 ÷ 300mm, distribute and level the material with a notched trowel of the following specified notch size. Use a specific roller to help the leveling and escape air.

Note:

  • The maximum application time is 30 minutes after mixing. The maximum thickness is 5mm/ layer. Do not mix material by hand.

Safety:

  • BestFloor PC302 has alkalinity and skin allergy. Do not contact it for a long time. Should wear gloves, masks, and glasses. In case of accidental eye contact, wash with fresh water and seek medical advice immediately.
