Finnseco Kuitulaasti

Polymer-modified fiber-reinforced cement-based thin render with a maximum grain size of 0.6 mm.

Used in insulating rendering systems as adhesive, reinforcing and leveling mortar and as leveling mortar for concrete, block, board and brick structures.

Residential, commercial, industrial and storage buildings and others.

1,5 kg/m²/mm. For gluing insulation approx. 4 kg/m², for reinforcement approx. 9 kg/m² (layer of thickness 6 mm)

The temperature of air, mortar and substrate must be at least +5 °C. Working in hot air, strong winds, direct sunlight, rain or before rain should be avoided.

The surface to be treated is cleaned of dirt, dust and salts with for example water pressure wash. Surfaces with mold, moss etc. are cleaned with Tikkurila Mold Removal in accordance with the instructions. The outer uneven spots are removed mechanically, and the big cracks are filled with Finnseco KL+ Repair Mortar or another suitable mortar for the block. Surfaces on which additional insulation will be attached are corrected and reinforced in accordance with the specifications. Smooth, glassy concrete surfaces must always be treated mechanically to create a sufficient surface profile and remove the laitance. PREPARING THE MORTAR: Finnseco Fiber Mortar is added to clean water and mechanically mixed to an even mass, after which it is let to water for about 10 minutes before re-mixing and beginning to work.

First coat:

Gluing Liimalaasti (adhesive plaster) is spread out thoroughly with a trowel to the insulation boards. After this the boards are pressed to the substrate and pressed tightly together. There must be no mortar or open areas left in the joints. Netting Kuitulaasti (fiber plaster) is spread on top of the insulation or plaster boards, a layer of 3-4 mm with a mortar spray or with a steel trowel by hand. Finngard Fiberglass Mesh is embedded in the fresh mortar. The nets are interlaced at least the length of 100mm. A second mortar rendering is spread and finished at the earliest the next day after the spread of the lower layer. Filling The mineral substrate filling is done twice so that a protective and structure covering plaster is achieved. Finnseco Fiber Mortar is spread with a mortar spray or with a steel trowel by hand. If necessary, the plaster is fortified with Finnseco fiberglass net. The mortar must be let to harden one day per mm before other treatments.
