About this product

weber.joint color is a fibre-enhanced, polymer-modified grout for interior and exterior use. It can be used for grouting ceramic, porcelain, mosaic, quarry, natural stone, terrazzo and terracotta tiles and is available in 25 colours (see pages 62 – 63 for colour chart).

Constraints

Not suitable if grout is required to be chemically-resistant or completely impermeable.

Features and Benefits

Manufactured under BSI Quality Assurance Scheme ISO 9001
Suitable for areas that will be dry or intermittently wet
Suitable for joint widths up to 15mm
Very fine texture
Available in 25 colours
Can be used in conjunction with under-tile heating/warming
Limited flexibility, to accommodate some movement
Improved water resistance

Preparation

Ensure that the adhesive has set and dried, and that the tiles are firm.

Adhesive should normally be left for at least 24 hours before grouting, unless using a rapid set adhesive, when it should normally be left for 2 – 3 hours. Longer 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 completely impervious to water, or chemically resistant, use weber.joint epoxy.

Mixing

Mixing should be carried out using a slowspeed mechanical mixer.

Gradually add 2.5 parts of grout to 1 part (by volume) of clean water and mix to a smooth, stiff, workable paste. After mixing, allow the mix to stand for 5 minutes and add more powder if necessary. Re-mix thoroughly. 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

Do not use at temperatures below 5°C.
Using a squeegee or a rubber float, apply the grout to a small area at a time. Completely fill the joints leaving no voids. Excess grout should be removed immediately using a rubber float held at 90° to the tiles. This should be moved diagonally across the tiles to prevent removal of grout within the joints.

When the grout has started to dry, after 5 – 10 minutes (less at temperatures above 20°C) the tiles should be cleaned with an emulsifying pad. This should be used in a circular motion to loosen the grout residue. The tiles should now be wiped with a clean damp sponge until all residue is removed.

When dry, polish the tiles with a clean, dry cloth.

Tools and equipment should be washed in water immediately after use.

Warning

Some tiles may have a soft surface which can be scratched during grouting.
Some 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.
Certain 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 in these instances the tiles should be treated with an appropriate protective sealer that helps to stop grout sticking to the tile face.

You are advised to test the grout on a spare tile before proceeding.

Allowance for movement

Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS 5385:
a) where the tiling meets other materials (e.g. floor perimeters)
b) along all internal corners – vertically and horizontally
c) over existing movement joints or changes in background material
d) dividing large tiled areas into bays (every 3 – 4.5 m on walls)

Health and Safety

Contains cement.
