Mapei Flexible Wall & Floor Grout - Grey

Info needed: [The specific mixing ratio (grout powder to water) is not provided in the product description. Please refer to the product packaging or technical data sheet for precise instructions.]

Yes, this grout is suitable for both interior and exterior use, which generally includes areas exposed to moisture, such as showers. However, for continuous water immersion or very high moisture areas, ensure proper waterproofing of the substrate and consult specific Mapei technical data for wet room suitability.

The grout typically sets in approximately 24 hours. It is recommended to wait the full 24 hours before subjecting the tiled area to foot traffic or heavy items to allow for proper curing and strength development.

While suitable for interior and exterior use, which implies resistance to moisture, the product description does not explicitly state 'waterproof' or specific waterproofing ratings. For areas requiring full waterproofing, ensure the underlying substrate is properly sealed or waterproofed before tiling.

Clean tools immediately after use with clean water while the grout is still fresh. Once the grout hardens, it becomes very difficult to remove from tools.

Based on the provided product information, this specific variant of Mapei Flexible Wall & Floor Grout is offered in 'Cement Grey'. Other colors may be available within Mapei's broader grout range, but are not specified for this product.

This grout is suitable for joint widths up to 6mm. While it can be used with some large format tiles if they have narrow joint requirements, many large format tiles often require wider joints (e.g., 5mm or more) or specific flexible grouts designed for larger joints. Always ensure your chosen joint width is within the 6mm limit.

Ensure the substrate is stable and properly prepared before tiling. Verify that the grout was mixed with the correct water ratio (avoid too much water) and applied uniformly, allowing for full curing without premature traffic.

Check the ambient temperature and humidity; extreme cold or high humidity can slow curing. Ensure the correct water-to-powder ratio was used during mixing and that the product was within its pot life when applied. Avoid exceeding the recommended pot life.

Ensure consistent mixing of each batch of grout. Use the same batch numbers for a continuous area if possible. Clean tools thoroughly between batches. Avoid adding extra water to 're-mix' partially set grout, as this can affect color and strength. Ensure consistent moisture during initial clean-up.
