Glue for wool

Used to glue mineral wool boards to stable, mineral bases. The product is classified as mineral gluing ground, with very good gluing properties and very good initial adhesion. The addition of anti-shrinking fibres improves workability, provides a micro-reinforcement effect and significantly increases the durability of plaster. It is an integral element of product ranges in Greinplast W, WS and WX insulation systems (according to applicable AT’s) and Greinplast MW (according to ETA).A).

Packaged in 25kg containers.


Preparation of dry set mortar: Empty the package (25 kg) into ca. 6,2-6.7 l of clean water and stir well until a smooth mass is obtained. The volume of added water depends on the weather conditions and base absorbability. The mortar achieves its full working properties in 5 minutes, after which it should be stirred again. The usability time of mortar mixed with water is not longer than 2 hours.
Gluing mineral wool panels: Places in which glue will be laid on mineral wool panels should previously be luted with it. Glue on a mineral wool panel with lamellar fibre arrangement should be applied onto the entire surface, with a trowel with teeth sized at least 10 mm. On panels with chaotic fibre arrangement, glue should be applied along the edges, in belts at a minimum width of 3-4 cm, and on the remaining surface in several circles at diameters 8-12 cm. Panels thus prepared should be put on the wall immediately and pressed until even surface with the neighbouring panels is achieved. After placement, the overall surface of the applied gluing mass should cover at least 40% of the panel. Gluing wool panels with the application of only glue circles is not allowed.



Recommendations and remarks

The façade surface should be shielded against rain, wind and excess sunlight until it is completely dry. Do not carry out any works when the base temperature is lower than +5°C. The building thermal insulation design specifies the necessity for carrier pins and their type (usually, when mineral wool is used with a load-bearing base up to 12 meters, they are not required). When wool with chaotic fibre arrangement is used, carrier pins must be used in every situation. Glue in its autumn-spring version (as described on the unit package) should not be used in temperatures higher than +15°C. The product contains pigment. Do not use to sink reinforcement meshes. Any attempts to change the composition of the product are not allowed, as they may considerably reduce its quality. Information contained in the manual help ensure the optimal use of the product, however, it does not create any legal liability of the Manufacturer, due to the fact that the conditions of use remain outside of its control. Glue consumption depends on the evenness degree at the base.
