Glue for mineral wool
Used and to glue mineral wool boards to stable, mineral bases and to submerge fibreglass meshes (reinforcement layer). 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 ATâs) and Greinplast MW (according to ETA).
Packaged in 25kg containers.
Preparation of dry set mortar: Empty the package (25 kg) into 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.
Mesh sinking: The placement of a layer reinforced with a mesh on the surface of wool panels may take place only after 2 days have elapsed after gluing, and when the entire area has been previously floated and cleaned of loose fibres. Glue should be applied with a steel trowel at a thickness of ca. 2 mm, beginning from top, in belts at a width equal to that of the reinforcement mesh. Then, immediately sink the reinforcement mesh, pressing it into the mass with the trowel. At the next stage, apply a glue layer at a thickness up to 1 mm, until the mesh is fully covered. The entire thickness of the reinforced layer should be between 3 and 5 mm. Remember to retain 10-centimetre mesh margins where joints are located.
