Adhesive for Wool TO-KW

TO-KW adhesive for wool is part of the Termo Organika® thermal insulation system for affixing wool to mineral base surfaces, e.g. reinforced concrete prefabricates, concrete, ceramic, Lightweight Expanded Clay Aggregate (LECA), and aerated concrete elements, natural stone, cement, lime and cement/lime plasters, and similar surfaces. It can be applied in thermal insulation of both new and renovated buildings.

^*)At a temperature of +20°C and relative humidity of 60%. Low temperature and high humidity make the above durations longer up by several times.

 Preparation of the Surface

Every surface must be compact, smooth, loadbearing, dry, clean and without any film (grease, dust, etc.) which would reduce adhesiveness. Remove old “loose” plaster, peeling paint and other dirt. Minor uneven spots and cavities may be repaired with TO-KW adhesive. Repairs of the surface should be complete at least 1 day before the wool is affixed; the thicker the mortar layer the longer the time needed for the wool to be affixed (following the rule of: about 1 day for each 1 mm of the mortar thickness). Absorbent surfaces (e.g. aerated concrete) should be treated with TO-GU universal primer, and smooth and/or non-absorbent surfaces (e.g. concrete, reinforced concrete) with TO-GS contact primer.

 Implementation

Pour the bag content into a vessel with the recommended quantity of water and mix for 3-5 minutes with a low-speed electrical mixer until smooth paste-like consistency is achieved. Put aside the adhesive for approx. 2-3 minutes and mix again. The mortar is suitable for mixing in concrete mixPour the bag content into a vessel with the recommended quantity of water and mix for 3-5 minutes with a low-speed electrical mixer until smooth paste-like consistency is achieved. Put aside the adhesive for approx. 2-3 minutes and mix again. The mortar is suitable for mixing in concrete mixers. In such a case, the mixing duration should be extended to approx. 10 minutes. The consistency of the material can be adjusted by adding water, but in a quantity which does not exceed the upper limit. Prepare portions of the mortar which will be used within approx. 2 hours. Stir the mortar which has thickened in the meantime without adding water. Before affixing a panel of wool, apply a thin priming film of TO-KW adhesive. If the surface is smooth, apply a thin film of TO-KW adhesive on the wool panel and spread evenly with a toothed trowel with 10-12 mm teeth. Otherwise, spread the mortar circumferentially at a distance of approx. 3 cm from the panel edges, and additionally apply between 3 to 6 splashes evenly onto its surface. As a result, the mortar should be covering at least 60% of the panel. Then, affix the wool panel onto the wall, pressing it gently, and adjust it so that it fits tightly to the neighbouring panels. The subsequent rows of panels should be off-set in relation to the previous ones so that the panel joints are in a staggered arrangement. Affix the panels beginning with the baseboard at the bottom of the external wall. After the mortar is bound (after approx. 3 days), fix them additionally with expansion stud anchors with a metal pin. Start the studding, grinding of the panels and affixing the reinforcing mesh no earlier than two days after the affixing of the wool to the surface. The mechanical connectors must be appropriately chosen to match the surface type and in compliance with the thermal insulation technical design. Do not use rusted or dirty tools. Rinse off fresh smudges with water. After it hardens, the mortar can only be removed mechanically. The adhesive may not be mixed with cement, lime, sand, other adhesives, mortars and chemical additives. During the work, the temperature of the surface and the environment should be between +5°C and +30°C.

 Caution

The product contains cement and, after mixing with water, it creates an alkaline reaction. Do not inhale the dusts and avoid being splashed with the mortar. In case of contact of the product with eyes or skin, rinse them with plenty of water and consult a doctor, wash the skin with water and soap. Keep away from children. During work, wear protective clothing and eye protectors.

 User safety

In addition to the above recommendations, follow good building practice and work-safety rules. The manufacturer warrants the quality of the product but has no influence on the manner, place and conditions of its storage and application. Building work should be done by professionally qualified contractors.
