K OttO
White adhesive for exterior insulation boards and skim coat for panels and plaster.
Special white adhesive and skim coat with high bond strength, elasticity and impact resistance, compliant with ETAG 004, very low in volatile organic compounds, breathable, based on lime and special hydraulic binders, pure selected aggregates with a maximum grain size of 0.8 mm and additives, fully recyclable at end of life, suitable for:
- bonding and skim coating insulation boards (EPS, XPS, polyurethane foam, cork, rock wool, wood fiber, calcium silicate, etc.);
- skim coating new or existing plasters, outdoors or indoors;
- skim coating plasterboard, fiber cement and wood fiber panels;
- skim coating concrete.
As energy-saving regulations have steadily raised the thermal performance required of building envelopes, ever more efficient and thicker insulation materials have come into use in recent years. As a direct consequence, both the reinforced base coat and the finish on the boards are subjected to higher tensile stresses, caused by the temperature gradient between the board and the outside air.
K OttO is the adhesive and skim coat that keeps pace with the evolution of insulation systems, thanks to its high elasticity, workability, impact resistance, breathability, hygroscopicity and hygrothermal regulation.
K OttO is particularly suitable for bonding EPS, XPS, polyurethane foam, rock wool, cork, wood fiber or calcium silicate insulation boards to brick, porous brick, solid brick, concrete or concrete block walls or existing plaster, and for the subsequent skim coat with embedded glass fiber mesh of more than 150 g/m2, as a base for any kind of mineral finish (acrylic, siloxane, silicate, lime) or paint.
K OttO is suitable for skim coats with or without reinforcing mesh on new (provided fully cured) or existing plaster. It is suitable for skim coating plasterboard and fiber cement panels used in lightweight construction, after applying an acrylic primer and embedding a glass fiber mesh of suitable weight.
