Epo Inject MV3

Overview Details Application Documents

Product Description

Epo Inject MV3 is a solvent-free epoxy adhesive consisting of two pre-measured components, component A resin, and component B hardener that have to be mixed before use. Epo Inject MV3 has the liquid consistency that can be applied by brush on both horizontal and vertical surfaces. Epo Inject MV3 polymerizes without shrinkage and, after curing, is waterproof, possesses excellent dielectric properties and high mechanical characteristics in addition to its ability to bond concrete and steel. Epo Inject MV3 meets the requirements defined by EN 1504-9 “Products and systems for the protection and repair of concrete structures.

Field of Application

• Monolithic construction joints between fresh and hardened concrete.

• Bonding precast concrete elements.

• Bonding steel to concrete.

• Filling cracks in concrete.

• Construction joints for the structural reinforcement of beams and pillars.

• Construction joints on decayed industrial flooring.

• Rigid, waterproof construction joints.

• Reinforcement of beams by means of the béton plaqué technique.

• Sealing cracks in cement screeds

COVERAGE / CONSUMPTION

Consumption varies, depending on irregularities in the substrate and the method used in application.

Generally:

• Construction joints with a rough substrate: 0.5-0.7 kg/m²

• Construction joints with a very uneven substrate: 1.0-2.0 kg/m²

• Sealing cracks: 1.35 kg/l per liter of cavity

• Bonding precast elements in concrete, or steel-and-concrete: 1.35 kg/m² per mm thickness

Application Procedure

Preparation of the support

Before the application, the substrate must be perfectly clean, solid and strong. All loose and crumbling parts, dust, cement laitance and traces of form-release oils and paint must be eliminated by careful sandblasting or brushing. When applying the product to metal, remove any rust and grease residues beforehand, preferably by means of sandblasting to white metal.

Preparing the product

The two components have to be mixed. Pour component B into component A and mix with a trowel for small quantities or with a drill fitted with a low speed stirrer for large batches until the mix is perfectly smooth and even. Do not use partial amounts to avoid the risk of accidental ratio errors that could prevent from curing.

Applying the product

Epo Inject MV3 can be applied with a flat trowel or a brush on dry or slightly damp concrete. It is advisable to let the product penetrate well into particularly uneven and porous areas so as to ensure perfect adhesion to the whole surface being treated. The subsequent layer of fresh concrete must be placed within the open times according to the temperature indicated in the technical data table. When Epo Inject MV3 is used to seal cracks wider than 0.5 mm, simply placing is sufficient. In this case it is recommended to spread sand over the Epo Inject MV3 surface in order to favor bonding of product that may be applied subsequently. If the cracks are narrower than 0.5 mm, they have to be widened and then dusted well before repair work with Epo Inject MV3. Do not use Epo Inject MV3 when the outside temperature of the substrate is lower than +5°C.
