Product Description
ARDEX FLEX FL is a high-performance, rapid-setting flexible grout, engineered to provide durable, professional results for both internal and external applications. Perfect for outdoor projects, it excels in environments exposed to water, dirt, and temperature fluctuations, such as patios, balconies, and swimming pools.
With rapid-setting properties, tiles can be trafficked in just 90 minutes, minimizing downtime and ensuring fast project completion. The grout is formulated to provide a uniform, streak-free appearance every time, delivering a consistent and pristine finish. Its water-repellent and dirt-resistant properties ensure long-lasting, easy-to-maintain surfaces, even in wet or dirty conditions.
ARDEX FLEX FL is suitable for joints between 3-15mm wide and is compatible with almost all tile types, including non-moisture sensitive natural stone. It offers flexible performance, making it ideal for areas subject to movement, such as external floors and walls, providing a secure bond even under stress. The grout is also perfect for high-demand areas like swimming pools, patios, outdoor kitchens, and more, ensuring durability in any setting.
Designed for both commercial and domestic environments, ARDEX FLEX FL is the go-to solution for creating durable, attractive, and low-maintenance tiled surfaces, even in the most challenging conditions.
Key Features
Rapid Setting: Foot traffic can occur just 90 minutes after application at 20ºC, reducing downtime and enabling quicker project completion.
Waterproof & Durable: The hardened grout is unaffected by water, making it ideal for external tiling, including swimming pools in non-aggressive water conditions.
Consistent, Professional Finish: Delivers uniform, streak-free results for a flawless appearance every time.
Flexible & Versatile Performance: Perfect for areas with movement, such as external floors and walls, and ideal for high-demand areas like swimming pools, patios, and outdoor kitchens.
Preparation & Application
Ensure the tiles are securely fixed, and that the joints are free from dust, excess adhesive, bedding mortar, or other debris.
Mix Proportions:
The recommended mix ratio by volume is approximately 1 part water to 4 parts ARDEX FLEX FL powder. For a 10kg bag of ARDEX FLEX FL, approximately 2 liters of water is needed.
Mixing:
Add the ARDEX-FLEX FL powder to the appropriate amount of clean water in a clean container, stirring thoroughly until a creamy, workable mortar is achieved. For wall tiles with joints wider than 10mm, the mortar can be adjusted to a thicker consistency. The mixed grout has a working time of about 30 minutes at 20°C; higher temperatures will shorten, and lower temperatures will extend this working time.
Application:
Using a rubber squeegee or a rubber-backed trowel, press the grout firmly into the joints to ensure they are fully filled. Remove excess grout as you go, and wipe away any residue on the tile surface with a damp sponge within 30 minutes of application. If grout residues remain after 30 minutes, dampen the area with a fine mist from a suitable spray bottle to ease cleaning. Once the grout has hardened, any remaining dry film on the tile surface can be polished off with a dry cloth. Apply at temperatures above 5°C.
Note:
Coverage
The grout coverage depends on tile size, joint width, depth, and the Grout Coverage Figure. For ARDEX FLEX FL, the coverage figure is 1.75. To estimate the grout requirements for square or rectangular tiles, follow these steps (all measurements in mm):
1. Add the length and width of the tile.
6. Divide the result by the tile width.
This will give the material requirement in kg per square meter.
Example:
(1500 x 5 x 20 x 1.75) ÷ 900 ÷ 600 = 0.49kg/m².
This means one 10kg bag of ARDEX FLEX FL will cover up to 20m² of tiling. These calculations will vary depending on the joint dimensions.
