Application Instructions

SURFACE PREPARATION
Surfaces must be free of oil, dust, and dirt. Paint flakes, oil residues, frost, dust, and debris that may prevent adhesion should be cleaned.
 
MIXING PREPARATION
Components A and B must be mixed at specified ratios and stirred homogenously with a low-speed mixer for at least 3-4 minutes. After mixing, the product is ready to apply.
 
COATING SYSTEM
The surface to be coated should be primed with DFC-100. For moist surfaces, DFC-108 is preferred. Coating can be applied 24 hours after priming. Depending on the desired thickness, a notched trowel (with 1 mm or 2 mm notch spacing) is used to spread the product evenly on the surface. Air bubbles are removed using a spiked roller.
 
APPLICATION CONDITIONS
Concrete surfaces to be primed with epoxy must have a compressive strength of at least 25 N/mm² and tensile strength of at least 1.5 N/mm². On highly absorbent surfaces, continue applying primer layers until the surface reaches sufficient saturation. Even after curing, if pressurized moisture or water comes from the substrate, damage to the epoxy primer and polyurethane coating may occur. Avoid application below 10°C, above 40°C, and in environments with relative humidity over 70%.
 
SAFETY
This product is for professional use. Pay attention to the safety warnings on the packaging before use, and consult the Material Safety Data Sheet if necessary. Avoid inhalation, skin and eye contact, and ingestion. Use appropriate safety equipment. Take necessary precautions to prevent fire, explosion, and environmental pollution. Apply in well-ventilated areas.
 
TRANSPORT AND STORAGE
* Store the product between 5-35°C.
* Protect from direct sunlight.
* Keep opened product tightly sealed in its original packaging.
