It offers exceptional stain resistance, color consistency, and ease of application, making it a popular choice for both residential and commercial projects.
Before You Begin
- Surface Preparation: Ensure the tile surface is clean, dry, and free of debris.
- Grout Joint Width: Check that the grout joint width is within the recommended range (1/16" to 1/8").
- Mixing: Use clean, cold water for mixing. Do not use hot water.
Mixing Instructions
- Mix Ratio: Use a 2:1 ratio of powder to water (by weight).
- Mixing Method: Use a slow-speed drill mixer with a paddle attachment. Start by adding half of the required water to the container, then slowly add the powder while mixing continuously.
- Mixing Time: Mix for 2-3 minutes until you obtain a smooth, creamy consistency.
Application Instructions
- Apply Grout: Using a rubber float, apply grout to the tile joints, ensuring complete filling.
- Remove Excess Grout: Wipe off excess grout from the tile surface within 10-15 minutes of application, using a damp sponge and clean water.
- Grout Removal: For stubborn grout stains, use a grout removal solution designed for unsanded grouts.
- Drying Time: Allow the grout to dry completely before applying sealant.
Tips for a Professional Finish
- Clean Tiles: Keep the tiles clean during the grouting process by wiping frequently with a damp sponge.
- Grout Consistency: The grout should be smooth and creamy. Avoid over-mixing, as this can lead to air bubbles.
- Work in Small Areas: Apply grout to small sections at a time to ensure even coverage and timely removal of excess.
Sealing
- When to Seal: Seal the grout after it has completely dried, typically 24-48 hours.
- Sealing Recommendations: Use a high-quality grout sealer specifically designed for unsanded grouts.
Cleanup
- Tools: Clean all tools and mixing equipment immediately after use with clean water.
- Spills: Clean up any spills immediately to avoid staining.
Safety Precautions
- Eye Protection: Wear safety goggles when mixing and applying grout.
- Gloves: Wear gloves to protect your hands from irritation.
- Ventilation: Work in a well-ventilated area.
Important Notes
- Color Consistency: While Mapei Keracolor U offers exceptional color consistency, slight variations may occur.
- Shade Variations: Always order enough grout to complete the entire project at one time to ensure uniform color.
