Applications
BestPrimer EP601 has low viscosity and high penetration, making it suitable for use as a primer between surfaces requiring protection and BestCoat epoxy-based protective coatings to enhance adhesion.
BestPrimer EP601 can be applied to concrete floors, cementitious screeds, fiber cement panels, epoxy mortars, etc., in factories, warehouses, parking garages, and more.

Application instruction
SURFACE PREPARATION:
The substrate must meet the minimum strength requirements (compressive strength ≥ 20 MPa, tensile strength ≥ 1.5 MPa).
The surface must be level, sound, and dry (maximum moisture content of 4%). All contaminants, debris, and dust must be properly removed.
APPLICATION PROCEDURE:
Floor coating system:
For highly absorbent or weak substrates, apply at least 2 coats of primer before applying BestCoat systems.
For smooth, dense substrates with moderate roughness, apply 1 coat of BestPrimer EP601 after proper surface preparation.
For surfaces treated with hardeners, dilute BestPrimer EP601 with 10–15% BestThinner SC01 before application.
To achieve high aesthetics and required mechanical properties, the surface should be coated with at least 1 coat of BestPrimer EP601 and 2 topcoats or one self-leveling coating from the BestCoat range.
Mixing:
Before application, components A and B must be thoroughly mixed in the correct ratio using a mixer 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 at least 10–15 minutes, then remix before application.
Application:
Can be applied using a brush, short-nap roller, or spray equipment.
Notes:
Do not use material that has exceeded its pot life.
Ensure adequate ventilation during application and work in the direction of airflow.
Do not smoke during application.
CLEANING:
Use BestThinner SC01 to clean tools immediately after use and before the coating begins to cure.
SAFETY:
Both components are classified as hazardous and flammable and may cause allergic reactions on sensitive skin. Wear protective gloves, masks, and safety goggles during application. Avoid direct skin contact.
In case of contact with eyes, nose, mouth, etc, rinse immediately with plenty of clean water and seek medical attention at the nearest healthcare facility.
Keep away from fire, sparks, and heat sources during application.
