PREPARATION

CEMIX PRE-MIXED GROUT is ready to use. Before grouting, check the ease of cleaning from the face of the tile being used. The surface should be clean and free of loose and friable material and the tile adhesive well cured before applying the grout.

MIXING

No mixing required.

APPLICATION

To start, shake the bottle well and cut the tapered nozzle of the squeezy grout so that the opening of the nozzle matches the width of the desired grout. Apply the grout into the joints by holding and applying the grout at a 900 angle to the surface being grouted. Using a grout float or squeegee, ensure that the grout is compacted firmly into the joints. To minimise any excess grout from the surface, scrape the tiles with a grout float or squeegee. Allow the grout 15 minutes to firm in the joints. Using a small-pored sponge, remove any excess grout from the surface of the tiles by working diagonally across the joints. Ensure the sponge is frequently rinsed in clean water. When cleaning the tile surface, use a minimum amount of water. This will minimise water float shade variation and shrinkage. Once the CEMIX PRE-MIXED GROUT has hardened in the joints or is “touch dry” (approx. 6 – 24 hours), buff and polish the tile surface with a clean dry cloth. When grouting in external areas, ensure the grouted area is protected from all extremes of climate until full cure is reached after seven days.

DRYING TIME

The initial set is after 24 hours at 23°C and 50% relative humidity. Aftet this, shower walls can be exposed to water. Shower floors should be left to cure for 3 days before being exposed to water. The grout will reach full cure after 7 days. Allow longer for lower temperatures, dense tiles or high relative humidity.

LIMITATIONS

• Do not use in expansion or movement joints, use a coloured silicone in this instance
• Not suitable for use in immersed situations such as swimming pools
• Depending on the application some concavity may occur in wider joints
• Shade variation and efflorescence are caused by factors beyond the manufacturer’s control. This can include nature of cement, job site conditions, finishing techniques and uneven drying conditions
