ARDEX X 7 S1 and ARDEX X 7 R S1 W are rapid-setting, flexible adhesives designed for wall and floor tiling applications. These adhesives are highly polymer-modified and feature S1 deformability, utilizing advanced fiber technology to enhance adhesion strength, grab, and non-slip properties. They offer an extended open and working time, accommodating larger mixes and application areas compared to standard rapid set adhesives. Notably, grouting can begin just three hours after installation. Classified to BS EN 12004 C2FES1 as “Improved fast-setting deformable cementitious adhesive with extended open time,” these products are suitable for both internal and external tiling.
Key Points:
- Rapid-Setting and Flexible: ARDEX X 7 S1 and ARDEX X 7 R S1 W provide quick-setting capabilities while maintaining flexibility, making them ideal for a variety of tiling projects.
- Extended Working Time: With a longer open time than standard adhesives, these products allow for larger application areas and the ability to grout after just three hours.
- High Adhesion Strengths: The adhesives exhibit impressive tensile adhesion strengths, meeting or exceeding 0.5 N/mm² early adhesion and 1 N/mm² after various stress tests, ensuring durability for both internal and external applications, including swimming pools.
- Wide Compatibility: These adhesives bond effectively to a range of materials such as concrete, cement/sand renders, and tile backer boards, making them suitable for installations subject to limited movement and vibration.
Coverage
A 20kg bag of ARDEX X 7 R S1 or ARDEX X 7 R S1 W will produce approximately 14.3 liters of mortar, which covers around 4.7m² at a bed thickness of 3mm. The material requirement is roughly 1.4kg of powder per m² for each mm of thickness. Please note that actual coverage may vary based on the surface texture and flatness, as well as the trowel used.
Storage and Shelf Life
To ensure optimal performance, ARDEX X 7 R S1 and ARDEX X 7 R S1 W should be stored in unopened packaging, elevated off the ground, in a cool, dry environment, and protected from excessive drafts. When stored properly, the shelf life is 12 months from the date indicated on the packaging.

ARDEX X 7 R S1 and ARDEX X 7 R S1 W are perfect for installing fully vitrified or porcelain tiles, along with other low porosity tiles such as glass mosaics, porcelain mosaics, terrazzo, ceramics, and natural stone (excluding translucent types) and brick slips. For moisture-sensitive natural stone and agglomerated stone tiles, it is advisable to use an ARDEX ‘RAPIDRY FORMULA’ adhesive, such as ARDEX S 27 W MICROTEC or ARDEX S 28 W Natural Stone Wall and Floor Tile Adhesives. These adhesives bond effectively to a variety of construction materials, including concrete, cement/sand renders, screeds, heated subfloors, brickwork, blockwork, properly primed calcium sulphate screeds, tile backer board, and plasterboard. They are suitable for installations that may experience limited movement and vibration, making them ideal for both internal and external applications, including swimming pools.
APPLICATION
Apply the mixed mortar to the prepared surface using a trowel, then comb through it with a suitably sized notched trowel to create a straight ribbed adhesive bed. The size of the notched trowel should be selected based on the tile size, the surface being tiled, the profile on the back of the tile, and the required coverage. Tiles should be installed within the open time of the adhesive and pressed into place with a twisting and sliding action to ensure proper contact, as recommended in BS 5385. For wall tiling in dry internal locations, current British Standard Codes of Practice recommend maximizing the contact between the tile and adhesive. Tiles with a surface area less than 0.1 m² that exceed 70% of the background’s weight capacity should be solidly bedded. In wet areas such as showers and swimming pools, solid bed fixing is essential. For semi-pourable mixes, press the tile into place using a twisting and sliding motion, while with slump-free mixes, tiles typically need to be buttered immediately. ARDEX X 7 R S1 and ARDEX X 7 R S1 W have an open time of 30 minutes according to BS EN 12004: 2007 + A1: 2012, but for optimal performance, tiles should be fixed within 20 minutes. The mortar should be applied when temperatures are above 5°C.
GROUTING
Grouting can commence once the tile bed has sufficiently hardened to prevent dislodging the tiles, usually about 3 hours after application at 20°C. At this point, floor tiles can also tolerate light foot traffic. Note that higher temperatures will shorten this timeframe, while lower temperatures will extend it. For grouting tile joints, use the appropriate ARDEX-FLEX Tile Grout: ARDEX-FLEX FL Rapid Setting Tile Grout for joints between 3-15mm wide and ARDEX-FLEX FS Flexible Tile Grout for joints up to 4mm wide. In areas requiring enhanced chemical resistance, superior hygiene, or reduced maintenance, ARDEX EG 18 PLUS Epoxide Tile Grout is recommended.
