MAPEI Flexcolor CQ is a professional-grade, ready-to-use grout designed for both commercial and residential tile installations. Formulated with a color-coated quartz aggregate, it offers features such as stain resistance, ease of cleanability, and improved workability. The grout is suitable for use with porcelain, ceramic, and natural stone tiles in both interior and exterior applications. It eliminates the need for sealing and cures through natural evaporation, offering a cost-efficient and time-saving alternative to traditional Portland-cement grouts.
Key Features and Benefits
MAPEI Flexcolor CQ distinguishes itself through several key features. It is formulated to be stain and chemical resistant, negating the need for additional sealing. The grout’s composition ensures easy cleanability and consistent color throughout the installation. Workability is also improved due to the quartz aggregate formulation. The product is designed to dry to a hard, uniform color surface within 24 hours and will not stain surfaces.
The grout also exhibits crack resistance and shrinkage control, and is formulated to prevent efflorescence. BioBlock® technology is incorporated to provide resistance to mold and mildew. A specialized pail design with a flip-top hinged lid is included for ease of use. Comparative testing indicates that MAPEI Flexcolor CQ is 30% more cost-efficient and requires 65% less installation time compared to traditional Portland-cement grout.
Tile Compatibility and Testing
MAPEI Flexcolor CQ is generally suitable for use with a variety of tile types, including porcelain, ceramic, and natural stone. However, specific considerations apply when working with certain materials. When installing glossy wall tile, it is a suitable choice for most applications. For antique or handmade wall tile, a mockup or testing in an inconspicuous area is recommended prior to full application.
Similarly, when used with natural stone, particularly polished stone, testing is advised to ensure compatibility and prevent scratching. The grout is also appropriate for use with glass tile, but caution is recommended with delicate glass tiles, again suggesting a test panel be used. It is also a suitable choice for filling voids in travertine and limestone tile.
Application and Preparation
Proper surface preparation is crucial for successful grout application. The grout is designed to be used straight from the pail, eliminating the need for water addition. Essential tools for application include a grout float, a mixing bucket, a sponge, and a trowel. A National Tile Contractors Association survey indicated that using quality tools can reduce grouting time by up to 30%.
The grout spreads smoothly, simplifying the application process. It is suitable for all types of grout joints, ranging from very narrow gaps to wider spaces. For joints wider than 1/8 inch (3 mm), MAPEI Flexcolor CQ is recommended over alternatives like Keracolor S, which may result in hairline cracks and lower grout levels. For joints less than 1/8 inch (3 mm) wide, MAPEI Flexcolor CQ is preferred over Keracolor S, which contains sand that can cause difficulties in fully packing the joint.
Sealing Considerations
While MAPEI Flexcolor CQ does not require sealing, it can be sealed if desired. If a sealer is used, it should be a high-quality, water-based product. Testing the sealer in a small, inconspicuous area is essential to confirm compatibility. Solvent-based sealers are not recommended for use with MAPEI Flexcolor CQ grout.
Compatibility with Other MAPEI Products
MAPEI Flexcolor CQ is compatible with other MAPEI products. For example, MAPEI’s UltraCare Grout Refresh can be applied over the grout, provided the surface is thoroughly cleaned beforehand. An alkaline-based, stone-safe cleaner is recommended for cleaning MAPEI Flexcolor CQ prior to applying UltraCare Grout Refresh. When grouting unfilled travertine and limestone tile, MAPEI Flexcolor CQ is a recommended alternative to Kerapoxy CQ.
Addressing Specific Tile Types
The documentation clarifies specific recommendations for various tile types. Keracolor S is not recommended for use with travertine and limestone tile; MAPEI Flexcolor CQ or Keracolor U are preferred. Keracolor S should also not be used with glass tile due to the potential for scratching; Keracolor U or Flexcolor CQ are better choices, with testing recommended for delicate glass tiles. Similarly, Keracolor S may scratch glossy wall tile, making Keracolor U or Flexcolor CQ more suitable options, again with a test panel recommended.
Joint Width Considerations
The documentation highlights the importance of selecting the appropriate grout based on joint width. Keracolor S is not ideal for joints 1/8 inch (3 mm) or smaller, as it can lead to voids and eventual grout loss. Keracolor U, Ultracolor Plus FA, or MAPEI Flexcolor CQ are recommended for narrower joints. Conversely, Keracolor S may not be suitable for joints wider than 1/8 inch (3 mm), potentially resulting in hairline cracks and uneven grout levels. MAPEI Flexcolor CQ, along with Keracolor S and Ultracolor Plus FA, are recommended for wider joints.
Drying Time and Performance
MAPEI Flexcolor CQ is designed to dry to a hard, uniform color surface within 24 hours. The grout’s formulation provides flexibility, making it suitable for areas prone to temperature fluctuations, as it can accommodate movement without cracking. The advanced formula repels stains, contributing to the long-term aesthetic appeal of the tiled surface.
Conclusion
MAPEI Flexcolor CQ presents a professional-grade grouting solution offering ease of use, durability, and aesthetic benefits. Its ready-to-use formulation, stain resistance, and compatibility with various tile types make it a versatile choice for both DIY enthusiasts and professional installers. Careful consideration of tile type and joint width, along with appropriate surface preparation and testing, will ensure optimal results. The grout’s features, including BioBlock® technology and crack resistance, contribute to a long-lasting and visually appealing tile installation.
