Notes

  • The construction environment temperature should be 0-35℃, and the relative humidity should be 20%-80%.

  • When the temperature is too low, the drying process slows down; when it is too high, it causes difficulties in construction.

  • If the humidity is too low, it may cause incomplete drying, poor adhesion and other defects. If the humidity is too high, it is easy to have bubbles and heat rash.

  • For severely sandy and dusty floors, the amount of primer used will increase. It is recommended to use the primer to fully penetrate and reinforce until the overall color of the concrete is uniform without whitening, which can prevent the floor from peeling and hollowing.

  • When applying the topcoat by roller, it is necessary to ensure that the overall amount is uniform. There should be no flowing or piling of materials, otherwise the problem of mottling will occur.

  • After the colored paint is applied, the topcoat must be completed within the specified time; otherwise, it will affect the adhesion of the topcoat layer.

  • When applying topcoat containing red pigment, there will be a problem of floating color and mottling. It is recommended to switch to epoxy topcoat for construction.

  • This material has a strong odor. It is recommended to wear protective equipment during construction and avoid continuous construction for a long time.

  • The construction site should have good ventilation. Construction should be stopped when feeling unwell and ventilation and air exchange should be carried out in time.

Construction Process
Process Name Specific Methods & Requirements Single Coat Consumption (kg/m²)
Substrate Treatment 1. Substrate strength: Not less than C20 /
2. Substrate flatness: ≤5mm when measured with a 2m ruler
3. Substrate dryness: Moisture content of substrate surface < 8%
4. Repair hollowing and cracks on the ground in advance
5. Fully grind the concrete substrate
Primer Coat 1. Use single-component polyurethane paint: Roll evenly with a roller 0.1-0.15
2. Use a wool brush for edges, corners and machine corners
Mid-Coat Mortar Layer 1. Use OVG-0101/OVG-0102: Mix main paint and curing agent in proportion, stir evenly; add quartz sand in proportion and mix uniformly 0.3
2. Scrape overall with a trowel; adjust the number of coats as needed
3. After curing, grind and remove dust
Putty Layer 1. Use OVG-0101/OVG-0102: Mix main paint and curing agent in proportion, stir evenly; add appropriate fillers (quartz powder, talc powder) in proportion and mix uniformly 0.1
2. Scrape evenly with a trowel; focus on filling defects like pinholes and air holes; adjust coats as needed
3. After curing, fully grind and remove dust
Topcoat Layer 1. Use OVG-0101/OVG-0102: Mix main paint and curing agent in proportion, stir evenly 0.15
2. Dip the roller into the topcoat and roll evenly; require uniform coating with no missed areas
Finish Coat Use OVG-0101 (high-gloss): Stir evenly, then dip and roll uniformly 0.1-0.15


Construction section


Construction conditions

  • Air temperature: 0℃ - 35℃

  • Relative humidity: 20%-80%

  • Moisture content of the base material surface: < 8%

  • The construction site should have good ventilation

  • Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating

  • For specific details, please refer to the construction plan.
