  • Solvent-free.

  • Applicable as coating primer for highly humid concrete surfaces.

  • Multipurpose concrete primer.

  • Resistant to general cleaning chemicals.

  • Provides appropriate mixture ratio (2/1).

  • Ensures shiny film.

Areas of Use
  • Indoor and outdoor spaces

  • Shopping malls and supermarkets

  • On industrial surface systems as protective coating

  • Sewage and waste plants

  • Parking lots, walking trails

  • Pulp and paper factories

  • Warehouses and factories

  • PU and epoxy ground systems

Method of Application

Can be applied by roller, brush or squeegee. Continuous, non-porous layer of application should be ensured. If the surface of the primer is going to be covered with an epoxy or polyurethan coating; approximately 1 kg/m² of silica sand (0,1- 0,3 mm) should be spread on the surface while it is still tacky.

Do not keep the equipments in use for more than 30 minutes in the mixture; in case of delay, wash equipments with epoxy thinner. Even though YAPIFINE BASE EPOXY PRIME H is solvent-free, proper ambient ventilation will help protecting the operator, prevent condensation on paint film and ensure optimum coating performance. Ventilation should continue during curing as well.

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. 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 surface should be cleaned of all residual materials such as dust, oil, dirt, paint, curing materials, bitumen and other foreign substances.

The damaged sections of the concrete, the fractures and static cracks on the concrete surface should be repaired with the YAPIFINE MEND EPOXY 2C repair mortar.

After the surface preparation applications the surface’s pull strength should be min. 1,5 N/mm².

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. Avoid application under strong wind or 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

Both of the components are stirred inside their respective containers with a low speed mixer first.

Afterwards they are added to each other and are then stirred for a few more minutes until a homogeneous mixture is obtained. The mixture’s pot life at +25°C is 30 minutes.

Higher temperatures will reduce the mixture’s pot life and lower temperatures will increase it. Should not be mixed by hand.


Total theoretical consumption is 0.20 – 0.50 kg/m²
