FK 202

ΗIGH PERFORMANCE, FIBER-REINFORCED ADHESIVE & BASE COAT FOR THERMAL INSULATION BOARDS, WITH GEL PROPERTIES

High performance, fiber-reinforced adhesive & base coat for thermal insulation boards, with gel properties. Ideal for the adhesion of expanded polystyrene (EPS), extruded polystyrene (XPS) as well as mineral wool (MW) boards on surfaces of concrete, plaster or brick masonry. Reinforced with suitable fiberglass mesh, is used for the coating of thermal insulation boards, on external and internal surfaces of buildings. With Eurofins Indoor Air Comfort Gold certification ensuring that FK 202 complies with the strictest European regulations on VOC emissions.

Uses

Use it for coating of thermal insulation boards made of expanded or extruded polystyrene or mineral wool, in combination with appropriate MARMOLINE fibreglass mesh, on exterior and interior surfaces of buildings, before applying decorative plasters /renders. You can also use it as adhesive of thermal insulation boards, on surfaces such as concrete, bricks, plaster, cement blocks, aerated concrete, stone, etc., on exterior and interior surfaces of buildings. It is part of certified MARMOLINE MONOSIS external thermal insulation systems – ETICS.

Advantages

Excellent workability
High resistance to changes in temperatures (between heat and cold)
High bonding strength between substrate and insulation materials
High mechanical strength

Method of Application
Storage

The substrate must be stable, dry and free from dust, loosely attached particles and all kinds of dirt. In addition, the surface must be clean, without dust, salts or oil. For application on new plastered surfaces, at least 2 weeks must have passed since plastering. Highly absorbent surfaces are recommended to be primed with MARMOLINE MST 11.
Mix the content of a 25 kg bag, with 6,5 – 7 lt of water, using a low-rev electric mixer until a homogeneous, lump-free mixture is obtained. Leave the mixture to set for five to ten minutes and stir again.
As an adhesive for thermal insulation plates:
For smooth substrates: The adhesive is evenly spread and combed over the entire surface using a notched trowel at a thickness of 2 – 3
For uneven substrates: The adhesive is applied in stripes around the edges of the board and in 3 – 4 selected dabs in the center using a notched trowel.
The adhesive must cover 40% of the board surface.
As a reinforced base coat:
The installed insulation boards, on which the coating will be applied, must be “built” in the form of masonry and leveled.
Be sure to cover any gaps between the insulation boards with polyurethane foam.
Apply the mix all over the surface of the insulation board to a thickness of 2 – 3 mm.
Place the appropriate MARMOLINE MONOSIS 160 fibreglass mesh to the prepared surface and press with a spatula or trowel until the mesh is fully embedded in the adhesive. The strips of the mesh should overlap by 10 cm approx. Finally, smooth the surface, while simultaneously removing excess mortar.
