Here are examples of the application of the Re-Fleet method "RF specification." Concrete that has suffered from freeze damage has a weakened surface layer, so it is necessary to apply "RF-100" for alkalinity enhancement and surface strengthening. As a measure to prevent the recurrence of freeze damage in the future, we will fill in the damaged areas with polymer cement mortar "RF Mortar" and "RF Thick Mortar," which excel in waterproofing, freeze-thaw resistance, adhesion durability, and abrasion resistance, and perform surface finishing to ensure the repair effect is even more reliable. Additionally, for fire repair, the amount of "RF-100" to be applied is approximately 1000-1200g/m2, which is 3 to 4 times the usual amount, so please confirm the application quantity in advance. *For more details, please refer to the PDF materials or feel free to contact us.

By combining a specially formulated pre-mixed mortar powder with a dedicated admixture (polymer dispersion), we create repair polymer cement products that have physical properties such as strength, thermal expansion coefficient, and elastic modulus similar to concrete, while also excelling in durability, waterproofing, and long-term adhesion. The standard mixing time is set at 2 minutes after adding the pre-mixed powder. Please use a high-speed hand mixer (900-1300 RPM) for mixing. 【Mixing Method】 1. Measure the required amount of the dedicated admixture. 2. First, add about 80% of the measured dedicated admixture into the mixing container. 3. Gradually add the pre-mixed mortar powder while mixing. 4. After mixing evenly to avoid lumps, add the remaining approximately 20% of the dedicated admixture to adjust to a workable consistency. *For more details, please refer to the PDF document or feel free to contact us.
