Preparation & Application

Surface Preparation

The minimum joint width is 2 mm for walls and 3 mm for floors. Do not butt-joint tiles. Adhesive should be left to dry for at least 24 hours before grouting. If a rapid-set adhesive is used, kindly follow the manufacturer’s instructions. Longer drying times may be required on sealed or impervious surfaces.

Ensure that the tiles and joints are clean and free from grease or any other contamination. If the grout is required to be chemically resistant, use weber.grout Acid-resistant Grout WB235.

Mixing

  • weber.grout Tile Grout WB33 should be mixed with 1.35 litres of clean water per 5 kg bag to produce a thick creamy paste.
  • Allow the mixture to stand for 5 minutes.
  • Remix thoroughly before use.

If weber.grout Tile Grout WB33 is used in permanently wet areas, areas where food or cosmetic staining may occur, e.g. kitchens and bathrooms or if increased flexibility is required, the water in the mix should be replaced with weber.ad Bond-it WB183. Mix as above. Note that the grout will dry a shade darker.

Do not add too much water or attempt to extend the working time by adding more water as this will cause the set grout to be weak with a tendency to crumble. It may also cause surface discolouration and variation, especially with darker colours.

Application

Using a squeegee or rubber float, apply weber.grout Tile Grout WB33 liberally to a small area. Completely fill the joints leaving no voids. Excess grout should be removed immediately using the grout squeegee held at 90º to the tiles.

Move the squeegee diagonally across the tiles to prevent removal of the grout within the joints. Leave the grouted joints to harden for approximately 2 hours. The excess grout can then be cleaned off with a damp (not wet) sponge. Do not leave excess moisture on grout joints. The joints can be finished off by pointing along the joint lines. Allow the joints to dry for 24 hours before polishing with a clean, dry cloth.

Please note :

Some tiles may have a soft surface which can be scratched during grouting. Tiles with a matt or porous texture are prone to surface staining when coloured grouts are used. The use of an appropriate protective sealer is recommended. Natural stones such as limestone, marble, slate, sandstone and terracotta, will require sealing prior to grouting. Some tile faces have shallow depressions that can fill with grout.

This grout must be removed before it hardens. When using a grout that is a similar colour to the tiles, it can be difficult to see any residue that is left in these shallow depressions. It is recommended that these tiles be treated with an appropriate protective sealer that helps to stop the grout sticking to the tile face. It is advisable to test the grout on a spare tile before proceeding.

Coverage

Coverage Use the following formulation to calculate the quantity of weber.grout Tile Grout WB33 required per square metre of tiling:

kg/m2  = (A + B / A x B) x C x D x 1.7 

A = length of tile; B = width of tile; C = thickness of tile; D = average joint width
