Fields of application
weber.fug 870 is used as multi-use grout for walls and floors in domestic living rooms, bathrooms and showers, wet-duty areas and areas permanently underwater (for ex. fountains). For grouting mosaic, stoneware and earthenware.
weber.fug 870 is characterized by its smooth and easy workability, whereby the number of different joint colours offers gives the tile surface a perfect overall appearance. For use indoors and outdoors.
Main features

- class CG 1: CG: cement-based grout – 1: all characteristics comply with the minimum requirements
- for joint width up to 6 mm
- frost-resistant
- light-fast colours
- high filling grade
- strong adhesion to joint sides
- for walls and floors
- for use indoors and outdoors
General information
- Limits of use: do not use weber.fug 870 in drinking water tanks and in swimming pools; in these cases, use the high-strength cement-based grout (CG2 WA) weber.fug 873 or the epoxy resin binder mixed with sand weber.fug 878.
- Do not use for grouting natural stones, resin-bound slabs (“engineered stones”) and materials with sensitive surface; in these cases, use the ceramic and natural stone grout with crystal effect weber.fug 875 F.
- 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 materials 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, 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.
- 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 materials to be laid might have an influence on the final colouring of the grout; if necessary, carry out a test on a trial area.
- Due to several factors related to substrate and atmosphere, we cannot give a warranty for a uniform colour throughout all joints; if in doubt, carry out a test on a trial area.
- Do not use materials that have 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.
- In case of use in areas permanently underwater, a corrosion on the cement-based grout should be anticipated if the water is too soft. Therefore, the water must contain a minimum content of calcium carbonate per liter. Comply with the national standards and/or guidelines relating to the grade of local water hardness (for ex. hardness scale in Germany ˃ 5°); if not issued, request technical advice.
