De-coupled and impact sound-absorbing laying of ceramic tiles and natural stones on floorsverlegen
A solid installation of ceramic floor coverings and natural stones is not possible on critical substrates (e.g. on cracked substrates, mixed substrates, old coverings, wooden substrates and young concretes) in a direct bond. On these substrates, ceramic coverings have a tendency to crack or joints may break out and hollow layers may occur. To avoid this, the surface covering should be de-coupled from the substrate. In addition, measures for impact sound reduction (e.g. in the case of concrete, screeds) are often required, both for new construction and renovation. Depending on the specific application, Weber offers functionally reliable solutions on all vibration-free floors and stairs in interior areas.
Simple & safe to the goal
-
3. First use the primer for absorbent substrates weber.prim 801, diluted with water in a ratio of 1 : 1 part by volume or the bonding primer weber.tec 803 for non-absorbent substrates and timber.
-
Application with weber.sys 832
1. For high-load surfaces 5 KN/m2 use the impact sound insulation and de-coupling boards weber.sys 832.
-
2. Comb the quick-setting and flexible flow-grade tile adhesive weber.xerm 860 F or the dispersion-based tile adhesive in powder form weber.xerm 843 F with a notched trowel (notch size 6 x 6 mm).
-
Application with weber.sys 830
1. The impact sound insulation and de-coupling mat are pressed with a flat trowel or a wooden float on the freshly applied and combed 2-comp. tile adhesive weber.xerm 844.
-
3. The butt joints between the mats can be closed during installation in one step with weber.xerm 844, by using a flat or smoothing trowel. This avoids sound bridges. Masking the joints with adhesive tape is then no longer necessary.
-
Fixing of ceramic tiles
The functionally reliable installation of ceramic tiles or natural stones should then be carried out on the de-coupling system weber.xerm 844 with the quick-setting and flexible flow-grade tile adhesive weber.xerm 860 F.
-
Grouting
After hardening the tile adhesive, use the premium grout weber.fug 875 BlueComfort for grouting ceramic tiles or the ceramic and natural stone grout with crystal effect weber.fug 875 F for grouting natural stones.
-
2. Connection and movement joints must be closed with the elastic silicone joint sealant weber.fug 880 or weber.fug 881. In the case of natural stones, use the specific sealant weber.fug 883. For better bonding, use the primer weber.fug 884 (absorbent joint sides) or weber.fug 885 (non-absorbent joint sides).
