Ressi Insufix 200 is a general-purpose adhesive mortar for fixing expanded polystyrene (EPS) insulation boards to cementitious substrates. Ressi Insufix 200 is also used for the creation of reinforcing layers incorporating glass-fiber mesh applied onto Ressi Insufix 200 or Standard expanded Polystyrene insulation sheets. Ressi Insufix 200 is used as an adhesive over mineral based cementitious substrates such as concrete, blocks, bricks, plasters and renders etc.

PROPERTIES

Dual-purpose fixing & reinforcing mortar
Excellent adhesion to EPS and mineral substrates
Compatible with glass-fiber reinforcing mesh
Good workability and easy application
Uniform load distribution on insulation boards
Reduced risk of debonding and cracking
Suitable for interior and exterior applications
Cementitious, breathable system
Reliable performance on sound cementitious surfaces

MIXING

It is important that water is premeasured in accordance with the amount of material used. The amount of water required for the mixing of Ressi Insufix 200 is mentioned in the technical Table of this Technical Data sheet. The mortar powder should be added over the water to avoid the settlement of the material at the bottom of the mixing container. The mixing container should be uncontaminated, non-corrosive and clean. Only potable water should be used for mixing. It is also recommended that material should be mechanically mixed with a mortar mixer or other mechanical mixing methods to obtain a consistent lump free mix.

APPLICATION

Ressi Insufix 200 shall be applied onto a sound, clean, and properly levelled cementitious substrate, such as external cement-based plasters. The receiving surface intended for bonding expanded polystyrene (EPS) insulation boards should preferably have a slightly rough texture to ensure optimal mechanical adhesion.

It is recommended that Ressi Insufix 200 be applied over a levelled premix plaster conforming to BS EN 998-1, CS III or above, such as Ressi PlastoRend 120 or other Ressichem-recommended premix plaster systems. The plastered surface must be adequately cured, free from surface laitance, and exhibit controlled residual moisture with sufficient surface absorption.

In hot climatic conditions, particularly when ambient temperatures exceed 40°C, light water dabbing of the dry plaster surface may be carried out prior to application to reduce substrate temperature and enhance adhesive performance.

After proper mixing, Ressi Insufix 200 shall be applied uniformly to the EPS insulation boards as well as to the receiving substrate. The boards are then fixed onto the cementitious surface, including concrete, masonry, or plastered backgrounds. Care must be taken to ensure full adhesive coverage, avoiding voids or unbonded areas between the insulation board and substrate.

Once the EPS insulation boards are correctly installed and aligned, Ressi Insufix 200 is also used for embedding the fiberglass reinforcing mesh over the insulation surface. The mesh is subsequently rendered and levelled as part of the insulation build-up.

For detailed system configurations and application procedures, please refer to the Ressichem Insulation Systems Brochure and the EIFS solutions recommended by Ressichem.

SHELF LIFE

Expiration of Ressi Insufix 200 is at 12 months after production date under dry and sheltered conditions. Keep Away from Humid Environment to avoid lump formation.
