Fields of application
weber.fug 875 F specially developed for narrow joints of 1 - 6 mm, also in case of natural stone slabs. It is a high-quality grout for grouting wall and floor ceramic tiles, porcelain stoneware, stoneware, mosaic, glass and metal tiles, concrete stone slabs (for ex. terrazzo), natural stone slabs, artificial stones and cement-based tiles. This flexible grout stands out by a high abrasion resistance and a reduced water absorption (class CG2).
Furthermore, it is characterized by a smooth processing and easy washability, which enable fast and efficient grouting works for optically demanding coverings. For use indoors and outdoors.

General notes
- Limits of use: do not use weber.fug 875 F in areas permanently under water, like swimming pools, hydrotherapy baths, water tanks, fountains etc.; in these cases, use the high-strength cement-based grout (CG2 WA) for areas subject to high loads weber.fug 873 or the epoxy resin adhesive and grout weber.xerm 848. Furthermore, the product cannot be used for earthenware, terracotta and split tiles; in these cases, use a specific Weber grout, depending on material to be laid and joint width. Request technical advice.
- All characteristics mentioned in this data sheet are based on a temperature of +23 °C without draught and a relative humidity rate of 50%.
- High temperatures and low humidity rates accelerate, low temperatures and high humidity rates delay the setting process.
- Substrates with different porosity, type of material to be laid and joint sides can lead to colour differences once the grout has completely set.
- Mortar residues can accumulate on tiles with microporous (for ex. Lappato), porous, textured (rough) or matt glazed surfaces; if in doubt, carry out a test on a trial area to ascertain if discoloration is likely. If necessary, pre-wet the surfaces in order to prevent discoloration.
- For grouting natural stones and resin-bound slabs (“engineered stones”) follow the supplier’s recommendations; if in doubt, carry out a test on a trial area.
- Corner joints, connection joints to installed components and pipe ducts must be closed with an elastomeric silicone-based joint sealant, like weber.fug 880, 881 or 883 in accordance with the job site requirements.
- Type and appearance of material to be laid might have an influence on the final colouring of the grout; if necessary, carry out a test on a trial area.
- Do not use material that has already stiffened.
Special notes
- Do not use highly-acid cleaning agents or high-pressure/steam jet cleaners on the grouted surfaces.
- Wait for 14 days before using conventional household cleaners.
- In outdoor areas discoloration, washout and efflorescence due to environmental factors cannot be ruled out.
- The grouting of cement-based tiles is only possible on impregnated surfaces.
