BestBond EP750 Confix

• Permanent bonding for cracked or fractured concrete structures such as floors, foundations, tie beams, load-bearing girders, and basement walls.

  The product is also used to repair hairline cracks and as a protective layer for steel structural components such as anchor bases.

BestBond EP750 creates a bonding layer with significantly higher tensile strength than concrete. In addition, the product offers the following advantages:

• Easy and simple application, allowing for application at low temperatures.

• Easily fills small cracks, maximizing the restoration of original strength.

• Rapid strength development, shortening the time required for the structure to be put into use.

• Very high adhesion and tensile strength compared to concrete.

• Solvent-free, non-toxic, and environmentally friendly.

SURFACE PREPARATION:

• The crack surfaces must be clean, dry (surface moisture not exceeding 4%), and free from loose contaminants. Dust and weak particles must be removed by suitable mechanical preparation methods.

APPLICATION PROCEDURE:

Mixing:

• Before application, Components A and B must be thoroughly mixed in the correct ratio using an electric mixer or pneumatic mixing paddle operating at 300 – 400 rpm.

• Mixing time should be approximately 2 minutes or longer until a completely homogeneous mixture is achieved.

Application:

• Use a concrete drill to drill a hole (minimum depth 30mm) to insert the injection nozzle (one-way valve) at the lowest point of the crack.

• Use BestBond EP750 to seal the injection nozzle and the remaining surface of the crack.

• Use a self-propelled pump or a specialized high-pressure pump to pump the material until the crack is completely filled (material overflows at the highest point of the crack).

• BestBond EP750 will fully cure after 7 days from the date of application.

• In addition, other appropriate application methods may be used depending on the specific case.

Note:

• Do not use any mixture that has exceeded its allowable application time.

• To increase the application time, the two components can be cooled before mixing.

CLEANING:

• Use BestThinner SC01 to clean tools immediately after use and before the mixture begins to harden.

• Then wash again with clean water and soap.

SAFETY INSTRUCTIONS:

• The product is flammable; keep away from heat sources and open flames, and ensure good ventilation during application.

• The product may cause allergic reactions to sensitive skin after prolonged contact. Protective gloves, masks, and safety goggles should be worn during use.

• If the product splashes into eyes, nose, or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for prompt and proper treatment.
