Construction reference
Surface treatment
● For all new and old concrete floors, the concrete strength must reach C25 or above. The surface stains, loose soil, moisture, loose old paint film and other attachments must be completely removed until the solid concrete is exposed. For concrete contaminated by chemicals or other substances, they should be removed until the solid concrete is exposed. Make the surface clean, dry and flat.

● Old floors with paint
Completely grind away loose or incompatible old coatings to expose the concrete surface. Clean, dry and intact compatible coatings do not need to be removed.

● Oily floors
Oil stains will seriously affect the adhesion of floor coatings to the base surface. Oily floors must be completely cleaned and polished.

● New concrete floors
Make sure the floor has exceeded the maintenance period and the moisture content of the floor is less than 6%. It is critical to use mobile sandblasting tools and grinding equipment to treat the concrete surface to achieve the correct surface roughness.

Paint mixing method
Apply directly within the service life.
Construction conditions
Painting environment temperature range: 5~35℃. The base surface temperature is at least 3℃ higher than the air dew point temperature.
Painting environment humidity range: Relative humidity <85%
Ventilation conditions: Ensure that the construction site is ventilated and dust-free. However, there should be no strong wind to avoid bringing in dust and affecting the appearance.
Construction data
● Mixing period:
4 hours after opening the can
● Construction method

Airless spray, air spray, brush and roller
Roller coating Large area construction use
Spraying Can be applied using conventional air spray or airless spray
Brush It is recommended to use a soft-bristled brush for small areas.

● Thinner —

● Drying time and coating interval
It is related to the temperature and humidity of the coating environment. Usually, the coating interval is 12 hours under standard conditions (25℃, relative humidity 60%)

● Coating matching
Applicable substrate Cement or concrete floor
Applicable coating Epoxy primer
Solvent-free polyurethane midcoat, epoxy midcoat

Shelf life
From the date of production, if stored according to the storage conditions, the shelf life of the product is 12 months.
Storage and transportation
The paint should be sealed and stored in a dry, cool and well-ventilated place, avoiding high temperature and fire.
During transportation, the environment of the carriage should be dry and closed, the materials should be stacked stably, and the relevant regulations should be met.
Safety measures
Product safety and health data are available upon request. The following measures should be ensured during any paint application:

● Avoid contact with skin and eyes.

● If paint comes into contact with skin, wash with warm water and/or an appropriate detergent. If paint comes into contact with eyes, rinse with plenty of water and seek medical attention immediately.

● Ensure good ventilation.

● Paint contains flammable substances. Please keep away from sparks and prohibit smoking in the vicinity.

● Comply with all health and safety regulations on site.
