TENALUX 131 M is a ready-to-use one-component sealant, developed on the basis of MS polymer (silane modified polymer) in the form of a gray thixotropic mass. It is used for sealing joints, seams and cracks on horizontal, vertical and inclined building surfaces with a maximum deformation of ± 25% under increased regular and irregular mechanical loads. It has a high level of adhesion to various surfaces of building materials, as well as good strength and deformation characteristics after polymerization.

How to apply the sealant correctly?
The surface must be solid, clean and dry. Therefore, before applying the sealant, the treated surface must be cleaned of all impurities that reduce adhesion. If necessary, all surface defects, cracks and chips should be leveled using TEKNO repair compounds.
The sealing compound is applied manually using special syringes (pistols). The sealant cures as a result of a chemical reaction with air moisture. To prevent the sealant from coming into contact with the structural elements of the joints, it is necessary to use a polyethylene foam tourniquet or anti-adhesive compounds.
How does the deformation seam work?
To prevent the formation of a third plane of contact between the sealant and the structural elements of the seam, it is always necessary to use anti-adhesive compounds or sealing gaskets, such as, for example, a bundle of foamed polyethylene. To limit the depth of the sealant layer, achieve the recommended ratio of width and depth of the sealant, as well as to reduce material consumption, it is recommended to select the size of the sealing gasket taking into account the actual width of the seam. In addition, the use of cellular sealing materials reduces heat loss and improves sound insulation performance. It is necessary to follow the recommendations for the optimal width and depth of the seam for this sealant. Applying a sealant layer with a thickness less than the minimum recommended leads to a decrease in the durability of sealing the seam. Exceeding the maximum recommended thickness of the sealant layer causes high internal stresses that contribute to the appearance of cracks. Narrow seams must be enlarged with special tools to achieve the recommended width and depth. Seams that are too wide, as well as seams with a porous, fragile surface, should be treated with appropriate repair compounds.
