BestPrimer EP602

• BestPrimer EP602 has low viscosity and high penetration, making it suitable for use as a primer between surfaces requiring protection and epoxy-based protective coatings to enhance adhesion.

• BestPrimer EP602 can be applied to concrete floors, cementitious screeds, fiber cement panels, epoxy mortars, etc., for use in factories, warehouses, parking garages, and more.

• High permeability ensures strong bonding.

  Excellent adhesion to common building surfaces, including metal.

  Suitable for surfaces with high moisture content (relative humidity up to 8%).

  Allows surface moisture to escape during curing.

  High resistance to alkalis, corrosive agents, and chemicals.

  Easy to apply using tools such as brushes, rollers, and pressure sprayers.

  Long working time, easy application, and material savings. Environmentally friendly.

SURFACE PREPARATION:

Substrate conditions:

• The substrate must meet the minimum strength requirements (compressive strength ≥ 20 MPa, tensile strength ≥ 1.5 MPa).

• The surface must be level, sound, and not water-saturated. All contaminants, debris, and dust must be properly removed.

APPLICATION PROCEDURE:

Coating system:

• For highly absorbent or weak substrates, dilute the first coat with 10% clean water (by weight) and apply at least 2 primer coats before applying epoxy coatings from the BestCoat range.

• For smooth, dense substrates with moderate roughness, apply 1 coat of BestPrimer EP602 after proper surface preparation.

• For surfaces treated with polished hardeners, prepare the surface using BestCorros before applying BestPrimer EP602.

Mixing:

• Start the mixer or stirring paddle, then slowly add component A into component B (in the correct ratio) while mixing at a speed of 300–400 rpm.

• The minimum mixing time is 3 minutes, or longer until a homogeneous mixture is achieved. Allow the material to stand for approximately 5 minutes, then remix before application.

Application:

• Apply BestPrimer EP602 evenly over the entire surface using a brush, short-nap roller, or spray equipment at a coverage rate of 0.10–0.25 kg/m² per coat.

• Before applying the second coat or subsequent topcoats, ensure the previous coat is completely dry (non-tacky).

Notes:

• Do not exceed a consumption rate of 0.4 kg/m² under any circumstances.

• Ensure proper ventilation during application. Avoid rain and direct sunlight before the material has fully cured.

• Do not use material that has exceeded its pot life.

CLEANING:

• Clean tools with water and soap before the material cures.

SAFETY:

• Both components are non-hazardous and non-flammable but may cause irritation to sensitive skin. Wear protective gloves, masks and safety goggles during application.

• In case of contact with eyes, nose, mouth, etc., rinse immediately with plenty of clean water and seek medical care at the nearest healthcare facility.
