Safety, Health and Environmental Information:

  1. Flammable liquid. Do not leave it near high temperatures, sparks or flames.
  2. On skin contact: May cause moderate skin irritation. Avoid prolonged contact with skin. Use gloves made from materials that are resistant to solvents. Use soap and water to wash away paint stains on the skin.
  3. When inhaled: Causes irritation to the respiratory system. Use only in well-ventilated area. Avoid inhaling paint dust. Use a respirator with a filter that can filter out organic solvents.
  4. On eye contact: Causes serious eye irritation and reduced vision. Use goggles that cover both eyes. If paint splashes into your eyes, wash with plenty of water and consult a doctor.
  5. When swallowed: Very dangerous if swallowed. Keep away from food, drinks and reach of children. If swallowed, see a doctor immediately and bring the paint container or paint label with you.
  6. In case of spillage, collect with soil or sand or suitable absorbent material. Do not pour paint into drains, ditches or water sources.
  7. Waste and empty containers should be treated and disposed of in accordance with national and local regulations. Empty containers and other packaging should be remanufactured, recycled or disposed of by appropriate authorities.

Preservation and Storage:

Maximum 24 months. Store in a cool, dry place away from sparks and heat sources.

Do not remove the lid when not in use, place the paint can in an upright position.

Use immediately after removing the lid.

NOTE: The above information applies to products under specified test conditions. Because the conditions and situations in which the product is used are beyond our control, for specific instructions, please contact Colori paint company customer support. We may edit the technical documentation for the product without prior notice.

Surface preparation:

Remove surface, contaminants, coatings, curing compounds and all weak and loose materials. Prepare the concrete surface by diamond grinding, scratching or roughening the surface to provide a suitable surface for optimal adhesion.

Cut grooves 3mm wide and at least 5mm deep just inside the perimeter of the area and around drains, columns and overhangs where the Colori PU paint product will be applied.

Recommended paint scheme:

Paint products used Number of classes Dry paint film thickness
Solvent-based Epoxy Colori primer 1 - 2 50 microns/layer
Apply 1 layer of Epoxy Colori coating mixed with aggregate 1 1 - 2 mm/layer
PU (Polyurethane) coating in various colors 1 - 3 2 - 3 mm/layer

Theoretical coverage for recommended film thickness:1.9 kg/m2 for 1 mm thickness
5.7 – 7.6 kg/m² for a thickness of 3 – 4 mm

Depending on the temperature requirements of the project, PU paint is applied in different paint thicknesses.

Note: Theoretical coverage is calculated based on the solid content by volume of the material and is related to the thickness of the paint film applied on the standard surface and does not include loss. Due to environmental conditions, flatness of the surface, geometric structure of the object being painted, skill of the installer, construction method... the actual coverage will be calculated approximately for each case. specifically.

Construction data:

- A:B mixing ratio                                                   1: 1 calculated by weight (kg) )

- Mixing ratio A : B : C : CP                                    3 : 3 : 14 : 0.175 (kg )

- Additional accelerator for use at low temperatures:

1. ≤ 20°C                 0.1 % (3 g in 3 kg A)
2. ≤ 15°C                  0.2 % (6 g in 3 kg A)
3. ≤ 10°C                   0.3 % (9 g in 3 kg A)

- Working time (25°C) Approx. 20-25 minutes

- Application temperature 10 – 30°C (minimum 3°C above the settling point)

Diluent: Epoxy Colori solvent

Cleaning solvent: Epoxy Colori solvent

Note: All equipment must be cleaned immediately with solvent after use. Alternative solvents not specified or supplied by Colori Paint Company but used for dilution may seriously affect the product and are automatically not guaranteed or warranted.

Drying Time:

Temperature              10°C          20 °C            30 °C
Dry to the touch        16 hours     10 hours       6 hours
Hard dry                    24 hours     20 hours      16 hours

Transition time between 2 coats of paint: Minimum 8 - 12 hours

Environmental conditions during construction:

  1. Do not construct when humidity is greater than 85%. The temperature of the surface to be painted must be at least 3oC higher than the dew point.
  2. Do not apply when the ambient temperature is lower than 7°C. Because if applied, the drying time and transition time between coats of paint will be longer.
  3. Must ensure ventilation during construction, do not use near fire sources and do not smoke.
