Use the following formulation to calculate the quantity of Weber.Acid-resistant Grout 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  

Ensure that the joints are free from tile adhesive and any other foreign matter. Allow 6 hours before grouting with Weber.grout Tile Grout.

Allow 48 hours for sealed or non-porous surfaces.

In wet or permanently wet conditions, replace the water in the mix with Weber.ad Bond-it.

• Tylon Acid-resistant Grout should be mixed with 1.35 litres of clean water per 5kg bag to produce a thick creamy paste.

• Allow the mixture to stand for 5 minutes.

• Remix thoroughly before use.

If Tylon Acid-resistant Grout is used in permanently wet areas, the water in the mix should be replaced with Tylon Bond-It. Mix as above. 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.

Using a squeegee or rubber float, apply Tylon Acid-resistant Grout liberally to a small area. Completely fill the joints leaving no voids. Excess grout should be removed immediately using the grout squeegee held at 90 degrees 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 45 minutes. 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 2 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 before grouting. 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.

When stored, unopened in a dry place at temperatures above 5^oC, shelf life is 6 to 9 months from date of manufacture.

Contains cement, which is alkaline when wet and can cause skin irritation. Use eye protection and gloves and avoid prolonged skin contact. Avoid inhalation of dust. Wash skin contamination away with warm soapy water. Remove splashes to the eyes by prolonged irrigation and consult a doctor. Do not ingest.
