Application
In corners, expansion joints, butt joints and movement joints, first insert all the necessary components of the sealing system weber.tec 828 (such as sealing tape as well as inner and outer corners) into the freshly applied layer of the highly flexible 2-comp. waterproofing and tile adhesive weber.xerm 844.

4. The second layer of the flexible slurry weber.xerm 844 can be applied with a flat trowel in a rich and uniform layer. The minimal dry layer thickness of both waterproofing layers must be ≥ 2.0 mm.
-
5. After drying of the waterproofing, the tile adhesive for ex. weber.xerm 844 is applied. Before a skin starts to form (check the tackiness of combed down tile adhesive with the finger) slide the tiles into the fresh mortar bed and press down. Scrape the joints before the tile adhesive hardens.

7. Connection and movement joints must be closed with the elastic silicone joint sealant weber.fug 880 or weber.fug 881. In 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).
