Ready-to-use, one-component grout designed for porcelain, ceramic, glass, quarry tile, and most moisture-insensitive natural stone. Stain-resistant, water-repellent, and highly flexible, it delivers easy application and long-lasting performance for interior floor and wall installations.
Ardex DG 1 One-Component Grout is a premium ready-to-use grout designed for convenient, high-performance tile installations in both residential and commercial environments. Eliminating the need for mixing or adding water, it simplifies installation while delivering consistent color and reliable performance.
Formulated to be stain resistant, water repellent, and highly flexible, Ardex DG 1 provides durable grout joints that resist cracking, efflorescence, mold, and mildew. Its thicker consistency makes it especially suitable for vertical surfaces, allowing for smooth application directly from the pail.
Ideal for interior dry and intermittently wet areas such as shower walls and floors (non-submerged), this grout works with porcelain, ceramic, glass, quarry tile, and most moisture-insensitive natural stone. It cures naturally through evaporation and requires no sealer, helping streamline project timelines while ensuring long-term performance.

Applications
Interior floor and wall tile installations
Shower walls and floors (non-submerged)
Residential and commercial projects
Dry or intermittently wet areas
Grout joints from 1/16" to 1/2"
Not Recommended For:
Moisture-sensitive stone
Distressed or tumbled travertine
Pebble-stone or river-rock tile
Irregularly shaped tile or stone
Steam rooms or saunas
Submerged installations
High chemical resistance or heavy industrial applications
Grout joints from 1/16" to 1/2" (1.5 mm to 12.7 mm)
Dry or damp substrates (no standing water)
Interior areas dry or intermittently wet, such as shower floors and walls (not submerged)
Use with most common tile types (Not for moisture-sensitive tiles / stone, distressed or tumbled travertine tiles, pebble-stone or river-rock tile or irregularly shaped tile or stone)
Not for high chemical resistance or specialized applications, commercial kitchens or other heavy industrial applications where fatty acids are present and/or where no-rinse enzymatic cleaners will be used, steam rooms or saunas or areas exposed to continuous high surface temperatures (greater than 140°F / 60°C, such as near fireplaces or wood stoves)
All dry times are calculated at 70°F (21°C). Drying time is a function of jobsite temperature and humidity conditions. Low substrate temperatures and/or high ambient humidity will extend the drying time. Adequate ventilation and heat will aid drying. Grout dry times are also affected by tile porosity and grout joint depth.
