• BestPrimer EP601 is low viscosity compound, high permeability. Used to make a primer layer between the surfaces to be protected and the coating BestCoat layer, epoxy based to improve the bonding strength.
• BestPrimer EP601 can be applied to floors of concrete, cement plaster, fiber cement panels, epoxy mortar ... workshops, warehouses, parking garages, ...

• High permeability should be able to link inside the material deeply.
• Linking well with all material surfaces, including metal surfaces. 
• Improve the aesthetic and materials savings for next coating. 
• Alkali resistance and high corrosion resistance. 
• Easy to apply by popular tools such as brush, roller, nozzle ...
• Easy to apply and materials saving because of allowing time application is long.
• Level of consumption density is very low, so it should be economic and efficient.
• Can be diluted with solvent to adjust the viscosity appropriate for each specific application cases.

Substrate requirement:

• For strong absorption and soft surfaces: Apply at least 02 primer layers before coating BestCoat lines. 
• For flat surface, solid and average roughness: Apply 01 primer layer. 
• For hardener surface: Dilute BestPrimer EP601 with 10-15% of BestThinner SC01 before application. 
• To achieve higher aesthetic and mechanical properties as required, the surface should be applied at least 01 layer of BestPrimer and 02 layers of coating paint or self-leveling paint of BestCoat lines.
  

Substrate preparation:

• The concrete floor shall be cured for minimum 28 days, compressive strength: ≥ 20 MPa, and tensile strength:  ≥ 1.5 MPa.
• The concrete floor shall be waterproofed against ground moisture and hydrostatic pressure, with moisture content ≤ 4%. The concrete floor shall be steel trowel (or power floats) to specific levels and falls.
  

Mixing:

• Two components A and B should be mixed thoroughly with mixer speed 300÷400 rpm.
• The mixing time at least is about 03 minutes or longer untill materials is homogeneous as required. Keep materials is about 10-15 minutes and mixing again before application.
  

Application:

• Applied by a roller, a short brush or high-pressure nozzle.
• Note: Do not use materials that timed out applying and begin curing. The application area should be cool and application instruction should be downwind. Do not smoke during applying.
  

Cleaning:

• Clean tools, and equipments with clean BestThinner SC01 before product hardening. 

Safety:

• Both of two components are hazardous, and flammable, therefore, they are required to be placed distant from heat or fire during the execution or preservation. This product can cause allergic to skin, therefore should be prevented from directly skin contact. Should wear gloves, masks and glasses while handling the product. In case of accidental eye contact, wash with fresh water and seek medical advice immediately. Keep away from fire, spark and heat sources when application.
