ReArm Bond 4031

Surface Preparation:

The surface must be sound, clean, and free from dust, laitance, grease, rust, and other adhesion-inhibiting contaminants. Depending on the substrate condition, prepare the surface using scrabbling, grit blasting, water blasting, or shot blasting.

• Substrate Requirements:

Cement-Based Surfaces (Concrete):

• • Minimum concrete grade: C20/25
  • Minimum substrate age: 14 days
  • Tensile adhesion strength: > 1.5 N/mm²

Iron & Steel Surfaces:

• Abrade to a bright white metal finish in accordance with Swedish Standard SA 2½

Priming :

ReArm Bond 4031 does not require priming and can be applied directly to the prepared substrate.

Mixing :

ReArm Bond 4031 is supplied in a pre-measured mixing ratio.
Pour Component B (hardener) completely into Component A (resin) and mix mechanically using a slow-speed drill (300–400 RPM) until a uniform, lump-free mixture is obtained.
Scrape the sides and bottom, transfer to a clean container, and re-mix for 3 minutes. Ensure the material temperature does not exceed 25°C during mixing.

Method of Application :

Apply ReArm Bond 4031 evenly on the prepared substrate using a trowel, steel float, or notched trowel, maintaining a minimum adhesive thickness of 2.0 mm.
For anchoring applications, fill the prepared hole completely, compacting the material to avoid air pockets. Insert the reinforcement bar with a gentle twisting motion until fully embedded.

Curing :

Protect the uncured product from rain and running water. Once fully hardened, no curing is required.
