  • Elastic structure.

  • Ensures joint-free, monolithic surface.

  • Easy to clean.

  • Hygienic.

  • Does not require maintenance for a long time.

  • Easy to apply.

Areas of Use

  • Factories

  • Storage areas

  • Parking lots

  • Concrete floors requiring chemical and mechanical strength

  • Floors requiring high abrasive resistance and strength

  • Stores and offices

  • Cold storages

  • Schools and hospitals

Method of Application

Before beginning the application the relative humidity and the dewpoint should be checked, and then begin the application only if the appropriate conditions are met. YAPIFINE BASE PU is poured onto the primed surface. The product is then spread onto the surface with a notched trowel. Afterwards a spiked roller is used in order to remove the trapped air from the material. The prepared mixture should be used within 40 minutes.

Packaging
  • Tin drum set of 20 kg + 5 kg
Storage and Shelf Life

The shelf life of the product is 12 months when it is stored on wooden pallets in a cool, dry and moisture free environment with an ambient temperature between +10°C and +25°C. The opened material should be used as soon as possible.

Safety Measures

No smoking should take place during application. The work environment should be well ventilated and should not include any open flames. Ensure well ventilation in enclosed spaces. Since the solvents are heavier than air it should be remembered that they will be in circulation over the floor. The operator should be wearing proper work attire, goggles, mask and protective gloves appropriate to work and worker safety regulations. In case of contact with the eyes, rinse with plenty of water before seeking immediate medical attention. For further information on the safe handling of this product please read the Safety Data Sheet (SDS).

Surface Preparation

The concrete floor should be clean, strong and at a minimum standard of C25 and preferably on a C30 - C35 standard. Concrete surfaces should be prepared so as to ensure porous surface upon removing cement grout. Surface moisture should not exceed 4% pbw. Do not apply on concrete surfaces with rising humidity conditions. Application surfaces should be sound, clean, dust-free, and free from molding oils, curing material, bitumen and other foreign substances. Such materials as mortar and cement residues should be peeled off. If possible the surface should be cleaned by washing it down with pressurized water and drying afterwards.

Application Conditions

Should not be applied to surfaces that were exposed to sunlight for too long or to surfaces that are too hot or frozen. Should not be applied when the ambient temperature is not within the values of +5°C and +30°C. The application area should be protected from the effects of wind and direct sunlight. Do not step on the surface during first 24 hours after application. Surface should be protected against direct water contact for 48 hours. The final consumption amount might vary depending on application conditions and surface characteristics.

Mixture Preparation

Component A is stirred in its own container with a low speed mixer (300-400 rpm) until it becomes homogeneous. Afterwards Component B is added into A and the mixture is stirred for 2 more minutes for it to become homogeneous as well. Avoid overmixing in order to lessen the effects of air entrainment.

Consumption

2.4 kg/m² for 1.5 mm thickness (without sand)

Lining

Prefer YAPIFINE BASE EPOXY PRIME for lining. Lining agent is applied on surface in an even manner with appropriate brush,
without allowing ponding. Once the primer dries, proceed to application. In case surface humidity is found to be beyond
standards, prefer YAPIFINE BASE EPOXY PRIME H Humidity-Tolerant Primer.
